Moderator note:
Some posts about Minolta RD-175 camera were moved from the http://www.dyxum.com/dforum/a-and-emount-camera-index_topic102992.html - A- and E-mount camera index thread to this new thread by http://www.dyxum.com/dforum/member_profile.asp?PF=5912 - rovhazman .
I find the information that was added about this historic camera very knowledgeable and useful and think it deserves a separate thread on its own


I see that the Minolta RD-175 is missing from A- and E-mount camera index. After all it is a digital SLR camera using the A-mount.

Unfortunately I can longer track down the thread where this was discussed previously, but it was decided not to include it because of its severe limitations in terms of the post-KM7D world, not the least of which was the lack of ability to review shots in the field, limitations with the recording medium and a minimum aperture of f5.6.

FYI I tracked some posts down which mention some of these handicaps.

If you do an "Any date" search on "RD-175", you will see one name in many of the results, that of ffrolvaag who has resolutely stuck with his own RD-175 and both posted many shots and also used it in Dyxum competitions.

I am sorry that I have not read the forum carefully enough. I thought this listing should cover all digital SLR/T cameras from Sony and Minolta using the A-mount regardless limitations in handling. A kind of retrospective complete overview of the development of Minolta and Sony digital cameras with exchangeable lenses if you like. I should have known better.

Please forgive my ignorance.

It's not a matter of ignorance or otherwise. It's a matter of a decision by the administrators of Dyxum as to where the start point for digital a-mount bodies should be.

As ffrolvaag points out the original price was in the vicinity of USD$10,000 and "features" were
- The max aperture (meaning widest open) is f6.7 due to light loss of the 2x crop factor
- Static ISO800
- Fully compatible with xi series flashes (3500xi and 5400xi) including wireless control, and ratio functions.
- Recording media is a PCMCIA hard drive
- Full resolution is 1.75 mp
- Raw files are a unique since camera raw didn't exist when the camera was produced. Through the Minolta legacy software, the raw can be converted to TIFF or JPEG. At one point, Adobe supported the raw files, but that functionality has been lost for a long time in ACR.
- x-synch speed is 1/90 sec.
- it had a 0.5 fps shooting rate (that is one frame per two seconds)

They were, as I understand, primarily used tethered as studio cameras for product photography. (I saw one in use for that by a catalog photographer.) Production was very limited.

Added later: http://www.epi-centre.com/reports/9605cs.html - This article points out that the RD-175 was based on the Dynax 500Si rather than being a from-the-ground-up digital design.

If you look over at http://www.mhohner.de/sony-minolta/bodies.php - Michael Hohner's site you will see two earlier attempts at digital - one based on the SPxi and one a digital back for the 7000/9000 AF.

These were also x2 crop - I've never heard of anyone actually using any of them though, I would imagine they were pretty expensive.

I've recently purchased an RD-175 in fully working order and I think this camera IS the ancient of ALL A-mount DSLR's, so It's a sort of "shame" that it is not included in Dixum's A-mount DSLR's cameras data-base.

This is only my opinion, not a complaint....

to Brettania (and to everyone is interested in the RD-175):

- 3 CCDs are green, green and red/blue (the third one has a twin filter)
- the camera needs three different batteries: one CR2025 for internal
clock, one 2CR5 for the ex-500Si camera section (shutter,exposimeter,
built-in flash) and one BIG NP-500H rechargeable lithium battery for
the digital back. Please remember that the PCMCIA original hard drive
(Maxtor Mobile Max - 131 Mb) is rated 5V/700mA, so the most of
"digital" power drain is due to HDD spin motor...
- first version of the Minolta legacy software was released for Windows
3.1 & DOS: the second version of that software is still downloadable
here: http://www.konicaminoltasupport.com/Older-Minolta-C.249.0.html?&L=0 - RD-175 Sw-ver2
I've tried it and surely works on Windows 2000, XP and Vista.
- there is an undocumented function in camera manual: you can release
shutter without lens attached ( or with an adapted lens with no chip
in the adapter )following these steps:
DISABLING THE LENS MOUNT CHECK
Press and hold DRIVE/SELFTIMER and AV buttons
and move power switch from LOCK to ON. (ON appears
in LCD panel)to re-enable lens check, re-do the same thing (OFF
appears on LCD panel).
- the RD-175 requires to be connected to computer to set Date/Time to be
included in EXIF; the hardware requested is nowadays weird & obsolete:
USB was not invented at the release of the RD-175, so SCSI-2 interface
was employed (faster than serial or parallel...), but a very uncommon
connector has been choosen for the camera:50 ways Half-Pitch    
Centronics.
I've made a cable with one of these connectors on a side and a
standard SCSI-2 50 ways high-density pin male connector on the other
side: the good info I can give you is that the 5o ways Half-Pitch
Centronics connector is pin-to-pin connected as its more common "big-
brother" 50 ways normal-pitch Centronics, that is the old, standard,
SCSI-1 connector. Remember that most of the recent SCSI boards have a
68 ways connector: to ensure compatibility to the old 50 ways, nine
signal lines (upper byte and its parity) must be active-terminated
into adapter. If your SCSI board is able to supply TERMPOWER to camera
trough cables and adapter, disable TERMPOWER on camera in order to
allow extended NP-500H battery lasting life ( with terminators
activated on camera, max. 2 hours, so Minolta's indication "connect
the camera to mains adapter when in use with computer" is near to be
mandatory...).

If one wants to revive an RD-175, please remember these things:

- you can use a standard CF card in conjuction with a PCMCIA to CF
adapter to substitute the PCMCIA hard drive: it works !
The CF card can be inserted into an USB card reader and the
propertary RAW files can be readed from CF with the "DISK" option
of the software linked above and converted into TIFF or JPEG.
The TIFFs are around 5 Mb each, while original RAWs are 1,2 Mb.
An hidden file is written by the camera on CF when formatting.
I've tried to format a CF off-camera (without SCSI connection ),
but it seems impossible. The good thing is that it is possible to
"prepare" a CF to be formatted out from every non-UDMA CF.
On my personal experience,the CF must be prepared using a partitioning
software utility ( EaseUS Partition Master 9.2.2 - Free Edition is
the one I've used ): on your CF erase all existing partitions and
create a new partition FAT ( DOS FAT-16)of maximum 256 Mb, with
unit letter "A" and make this partition active. DON'T FORMAT IT !
A value around 240 -250 Mb is prudential, over thed camera
displays "E8" as error on its LCD. Note that frame counter on the
RD-175 is a 2 1/2 digit one, so the maximum value it cans display
is "199". When the CF is ready, it must be putted into PCMCIA
adapter, the two things into the Rd-175, the camera connected to
the PC and the CF formatted. Note that this procedure permits you
to use any CF you want, but only 256 Mb of it will be used.
I think every "native" CF with nominal capacity below 256 Mb can
be formatted directly into camera, connected to PC, but I've
don't tried. I'm sure that my 1 Gb Sandisk ULTRA II cannot be
directly formatted in camera (error code E8), but one partition
on it of 250 Mb cans (199 free ...).
A very good workaround to format a CF without SCSI connection is
(as suggested       http://thecameracollectors.blogspot.it/2011/05/how-to-clone-minolta-rd-175-cards.html - Here ).
   The procedure is "restore a disk image" on a CF: the image is from
   a right formatted CF, destination is YOUR CF, so you can have
   easily a fully functional CF without connecting camera to PC via
   SCSI ! Note that the link give a 160 Mb image, if necessary I can
   supply a 256 Mb backup image or create a less capacity one (e.g.:
   128 Mb ). Every CF with free space over the one the image is
   suitable for use into the RD-175 (except UDMA ones....).
   I'm currently searching for a PCMCIA to Cf adapter suitable for
   CF Type II ( 5 mm. CF-II thickness, against 3.3 mm. type I CF ),
   to try to insert into the RD-175 both an IBM CF-Microdrive and
   an SD to Cf adapter, with a normal SD or... an EYE-fi one for
   wireless connection, but I suppose the last one will not work
   because its firmware probably search a "DCIM" folder with "JPEG"
   files....).

Last note for the braves who want to use an RD-175: the only issue due to SCSI connection unavailability is the missing of Time/Date setting
possibility (it will be recorded "randomly"): I've found that the old Sony NP-500H battery is replaceable with the much more common NP-F550.
The replacement is Info-Lithium, while the original not, but this is not an issue, the RD-175 simply don't care. You must only find a separate main adapter/charger for the NP-F550 ( I use an old Sony Mavica FD-200 to charge the battery, then I put it into the RD-175).
The 2CR5 6 Volts non-rechargeable Lithium battery is a bit expensive, so think twice before using built-in flash... ( a rechargeable 2CR5 does exist, but one must buy the relative chargher too...).
If this helps, Minolta states that "the external flashes guide number @ ISO 100 must be multiplied by a factor of 2.8" and this because both camera ISO is fixed at 800 and the camera crop factor of 2X is obtained
concentrating light by a lens group before splitting it on the 3 CCDs to rise ISO with optical amplification instead electrical one ( and thus reduce high-iso noise ): somethingh to similar to use an optical zoom instead of digital one.
I've not verified if the RD-175 requires full-frame coverage from lenses, despite its 2x crop factor, but the mirror seems to be the same of the film camera used as body and there is the real probably that the optical concentrator requires full-frame equivalent lighting coverage to avoid vignetting: there is not a Micro 4/3 sensor behind the mirror...


Finally, if there is one that owns a Minolta Vectis S1 or S100, one of the really few APS film cameras with detacheable lenses, a look around for a RD-3000 may be interesting..... ( and this is another DSLR that is unknow in Dyxum's data base, it's not an A-mount, none an E-mount, but the one-of-a-kind DSLR in V-mount...).


Please excuse me for this sort of "RD-175 review", but it is a my personal tribute to Minolta's engineers that in 1995 were capable to create a DSLR capable of results like this (JPEG converted by Minolta software, straight out the camera).

Thank´s for a very informative posting!

I whish it had been published a few years earlier when I did own a RD-175 that I got in a bundle with some lenses I wanted. At that time I could not find much info about the camera or any software so I eventually sold the camera and kept the lenses. Today, with your info and links, it would have been nice to use it as an oldfashion curiosity.

Hi Michael,

I own a RD-175 by only one month. Few years ago I didn't know absolutely nothing about it.
This is the first time I try to attach a file into a post instead of an image, but if works, you can download from the bottom of this post a backup image (made with the EaseUS software I talk above ) you can use to create a CF card ready to use into your RD-175 via a PCMCIA to CF adapter, without connect the camera via SCSI to a PC.
You have only to make a "Recover" of "Disk or partition" with the option "Sector by sector" of this 4,81 Mb file on a CF of almost 256 Mb.
Please be sure to do the recover ON THE CF, NOT ON YOUR SYSTEM DISK !
ALL DATA ON DESTINATION DISK WILL BE OVERWRITED !
If the procedure is done correctly, the RD-175 recognignes the CF as formatted by itself, 199 pictures to take (that is the maximum storage capacity allowed by the firmware/hardware of the camera).
Please refer to the tutorial linked in my previous post and..... tell us if works for your camera too !

Since I find the discussion about Minolta RD-175 very interesting, informative and knowledgeable, I think it deserves a thread of its own.
Therefore I moved the posts about it from the cameras index to a new specific thread.

Thank you Luca for all the info!

I recently bought an RD-175, which looks to be in near-perfect condition but I am having trouble getting the digital side of the camera to work.

I wonder if anyone can help?

I don't have a SCSI cable or card in my PC so I have gone down the route of formatting a CF card and placing it in a PCMCIA adapter. I have copied, using the Easus Todo Backup software, an image of the formatted Minolta PCMCIA card (linked to at the Camera Collector's blog referenced by Velocina above) to the CF card, sector by sector. I did this on a Windows 10 machine, but the disk is formatted as FAT (not FAT-32). The CF card is a Sandisk Extreme III 2.0GB. There is no mention of UDMA on the label.

When I put this card into the camera and switch it on, the LCD shows two charged batteries and then stops, displaying '- -' and P (for Program mode). The camera will autofocus, set exposure and set the WB when the shutter button is half-pressed, but it does not fire when fully pressed.

So near yet so far!

I will try Velocina's other card image, but is there anything else I should try in the absence of SCSI connectors etc?

(BTW, the camera came with a 130MB PCMCIA card, and when that is used after switching on it shows a rotating 'o' symbol and then stops with the message 'Er'.)

This little Minolta saved me on a job once. I'd rented the camera to play around and enter the digital age. Job was shot on film but I recorded everything twice to make comparisons.

As it turned out, the photo lab botched the film. Ruined everything, and I was in deep trouble because the job could not be done again... Yearly Corporate Policy Seminar for AT&T. We needed a 5x7 head shot for everyone attending from all over the country. Impossible to bring them back for a photo shoot.

Freaking out, I discovered that the RD-175 could produce a very decent 5x7 print from Kodak Dye Sublimation.

I delivered to client without saying a word about the lost film. They were thrilled and never knew the difference.

I turned to digital photography as soon as I could after that, incorporating it into any job that it could satisfy.

Long live film, long live digital!

I think I diagnosed what I did wrong with the CF card. It seems that it can be inserted either way up in the adapter I have and one way round it fails to work properly.

This is something that will vary from card to card and adaptor to adaptor I'm sure, but it is worth checking if future readers experience a problem.

If you're going to need to insert & remove something from a CF slot with any sort of frequency, be careful, because it's possible to bend the pins at the bottom of the slot, and this will usually spell the end of whatever device those pins are part of.

To add to the knowledge base here, I have tried the v2 software mentioned in Velocina's earlier post and it works on a Windows 10 PC, 2016 vintage. I can't even open the Mac software of a similar age. Who'd have thought that Windows would be the winner after 21 years?

The Minolta software does the best job of converting the files to TIFF format - GraphicsConverter v9 and Picasa also read these files but don't achieve the same tonality and more importantly, get the aspect ratio wrong. Something to do with the pixels not being square, I guess, but the file dimensions are slightly different too.

I have decided to start adding as much detail as I can to the database beyond the links. After not having touched my camera in a while, I pulled it out recently, and plan to start working with it some more. However, here are two common items that are easy fixes for very common issues I have seen with units sold on ebay. Pictures forthcoming.

1. Batteries - The original is a Minolta NP-500H, which is a 7.2v 1200mAh Li-ion battery. Although it is virtually impossible to find a functioning Minolta version, it is a the same size and shape as common camcorder batterys of the era. I have confirmed that Sony NP-F330, NP-530, NP-550 are all of identical size and will work in the camera with no issues. I have purchased several generic replacements of that type that also work. Replacements are cheap (5 USD + shipping) and plentiful, so fret not if your battery dies. See below for a photo of all of these various batteries. As you can see, there a couple of extra contacts for some of the Sony batteries, but the only important contacts for the camera is the two +/- pins on the sides (two small holes on either side of the bottom (on the picture) of the battery)



2. Battery Charger - Any Sony charger that will charge the above batteries will work. The main difference is that the Minolta charger has the ability to direct power the camera. The connector appears to be proprietary (off the charger, but not to the camera). If you want to find a charger that will work to charge batteries, I found that early Sony Mavica cameras that stored images on 3.5" floppy drives (MVC-FD92 etc) used NP-F330 and NP-F530 batteries. You can pick them up for cheap if you can't find a compatible generic charger. Just a small note, that if you buy a used Sony Mavica with charger and battery, buy it for the charger, and don't count on the battery being good as they are 15-20 years old by now.

As I get through more of my notes, I will continue to add details.

edit - Photo of batteries added.

Thanks for the update and good to know.
I think the last time I went to put my batteries on charge only a few were accepting any power .
The chargers were refusing to start for the others .

Lens Compatibility:

Non-chipped lenses do not work. The LCD will display the following, but will not allow activation of the shutter or focus confirmation in the viewfinder. Up until you try to activate the shutter, the camera seems to work normally.

(attached is a non-chipped 58mm f1.2 Rokkor)

Chipped MF lenses do work. The camera will try to AF these lenses if you leave it in AF mode. Focus confirmation does work as well. I have both a Pentax 50mm f1.2 and Nikkor 50mm f1.2 ais, both of which are chipped and do work.

SSM lenses will not auto-focus, but otherwise works normally. (Oddly enough, the the camera balances a 70-400G better than an a900 w/grip )

Otherwise, it appears that any other chipped AF lens I have tried works as intended.

A friend of mine who recently moved out of state gave me another RD-175. Along with all of the accessories, there were two marketing inserts he had from when he purchased the camera back in the mid-90s. I am uploading scans of the spec sheets and optional accessories lists from these inserts. Higher resolution color scans of the full Spec Sheet (6 pages) or Marketing Sheet (4 pages) are available upon request. The remainder of the documents is basically marketing fluff and camera layout photos.

Optional Accessories as listed on Spec sheet dated August 1996 (page 1 of 6)


If I have more time, I may end up breaking these into two separate posts and add the missing pages. For the time being, I want there to be a formal record of the technical specifications and accessories, as none truly exists in this post.

Today I am happy to report that I have future proofed (or at least greatly extended) the life of my RD-175. After a couple weeks of playing around, I have created a workflow to repeatedly to format a number of Compactflash (CF) cards in my RD-175's using windows XP laptop. The materials I used were:
1. Windows XP laptop with PCMCIA port
2. Adaptec 1460D SlimSCSI PCMCIA card with 50 pin centronics cable supplied with the card ($11 USD including shipping on Ebay). No drivers are necessary for this card with windows XP.
3. 50 pin centronics female to 50 pin centronics half pitch male adapter ($8 USD on Ebay)
4. PCMCIA CF adapter was plugged into the camera along with a 256MB or smaller CF card.
5. Minolta RD175 ver. 2.0 software along with the camera drivers previously installed on the computer (that was somewhat of an ordeal in itself).

Assuming you have these things, you can follow the exact sequence listed here on a XP laptop PC. If you deviate from this order in any way, the camera and computer will not recognize each other, so the order is critical.
1. Connect all the cables to both the camera and SCSI card. The camera and computer should be powered off.
2. Hold the "mode" button down on the camera for 3 seconds and then slide the the power button on from lock to on (still holding mode). "SCSI" and "ID-X" (where X is the ID #) will be displayed on the camera's display if done correctly.
3. Then you turn on your computer.
4. Open the Minolta RD-175 control software.
5. Select the "Settings" option on the menu.
6. Select the "Format" option.
7. Turn of the camera, close the software, and remove the CF card (or PCMCIA harddrive).
8. If you want to format another media, start at #1, and will need to restart the computer at step 3.

I think every "native" CF with nominal capacity below 256 Mb can be formatted directly into camera, connected to PC, but I've don't tried. I'm sure that my 1 Gb Sandisk ULTRA II cannot be directly formatted in camera (error code E8), but one partition on it of 250 Mb cans (199 free ...).


I can confirm that 256mb is the maximum native size. This is because I was repeatedly able to format multiple 256 mb CF cards using the process above, but was not able to format a 260MB PCMCIA harddrive (double the capacity of the 131 MB Maxtor drive that came with the camera). Apparently those 4 MB pushed it above the limit you noted.

As a general service announcement, I can provide anyone with the Minolta RD-175 drivers and control software free of charge (PC only). I do have the disks for Mac as well, but I am not sure how to copy them since I only have a PC, but don't want to part with them since they came with the camera. However, if you can't obtain all of the items I noted above (none of which came with the Minolta RD-175 except for the camera itself), I can either sell pre-formatted media, or format your 256MB or smaller media for you. You just need to send me a PM, and we can work out the details.

@ffrolvag - great work! Thanks for documenting this.

A quick search on eBay suggests you got a bargain in that adapter!

Yes, it does appear I did well. In my searching this was by far the least expensive SCSI adapter route at the time of this post. Adaptec made 1460A-D versions as well as a 1480 UltraSCSI version (more expensive). I see that the earlier versions are pretty cheap, but may not be fully XP compatible. Perhaps it was luck, but I happened to purchase two D versions for that price in separate auctions. All that being said, I strongly suspect any PCMCIA to SCSI or USB to SCSI cable will work as long as they are XP compatible. I would just urge anyone to search google for compatibility information on whatever card that they are considering to verify XP compatibility. Most of the SCSI PCMCIA cards are made for windows 98 an earlier computers and may have XP compatibility issues.

My next goal is to see if I can get this to work on my Windows 10 PC. The RD-175 software works, so it is just a matter of loading drivers and finding a compatible SCSI adapter for the computer. The newer computers have a smaller form factor for expansion cards than the previous generation of PCMCIA cards, so I will have to purchase another component to test this. At least I can now retire my windows 98 laptop, which I had maintained exclusively for the RD175.
