@ albnok, if it ever stops raining here!!!!!!!!!

I did do this with the 55-200, but I've not had the 70-300 all that long.

Cheers MIKE,

OK results for Tamron 70-300/4-5.6

f4   70-135
f4.5 135-210
f5   210-280
f5.6 280-300

These values do not change when Macro is selected (between 180-300)

Also interesting is that the EXIF reader I was using (Photome) changed its mind about the lens, depending on the focal length set
at 70 & 135 it suggested either 18-250 55-200 or 70-300
at 210      it suggested 18-250 70-300 or 200-500
at 280      it suggested 70-300 or 200-500

From that I assume that the Photome looks at the lens ID (in this case 255) and is also inteligent enough to take the FL set into account, it also must have some way of determining Tamron as IIRC there are other lenses with ID of 255.

The Tokina 80-400, at 80mm was shown as either the Min 28-85 or Tok 80-400, above 90mm only as itself,
Max aperture change points f4.5 80-150, f5 150-280, 5.6 280-400

The Sigma 600 mirror is not correctly recognised at all being shown as Min 300/2.8 Sig 50-500, Sig 170-500 or Sig 500/4.5 although the focal length is shown correctly elsewhere!

For what it's worth a couple of chipped M42 adapters, one from Hongkong showed as a Min 50/1.7, the Haoda showed as Min 50/1.4.
Cheers MIKE,

I see there is no activity on this post in the last four years....
but I think this is the right place for a technical question:

I have a Microchip "Pickit2" USB programmer for PICs, that can also be used to read/program 25LC0xx SPI serial EEPROMs. Can I use it to read data (EEPROM dump) from Minolta/Sony lenses's ROMs ?

Here some hints from Pickit2 ver.2.61 software release readme:

   Connections for 25LC devices
        ---------------------------------------
        PICkit 2 Pin             25LC Device Pin (DIP)

        (1) VPP                  1 nCS
        (2) Vdd                  8 Vcc
        (3) GND                  4 Vss
        (4) PGD                  2 SO
        (5) PGC                  6 SCK
        (6) AUX                  5 SI
                                 7 nHOLD - disabled (Vdd)
                                 3 nWP - disabled (Vdd)

( I think that nCS means negate CS, as !SS in Minolta pinout means negate Slave Select )

I'm planning to try to make an universal Adaptall-2 lens to Sony A mount universal adapter with embedded lens data base and mechanical diaphgram coupling using a metal eight contacts bayonet from an old Xi zoom and an original Olympus Adaptall-2 coupler ( that have a nice lever, close to the Sony-Minolta one )...

Bye.

This depends on the programmer. The Minolta lenses use a variation of the SPI protocol (with a somewhat non-standard timing), but different protocols and timings are used for extended data formats available in more modern lenses. Therefore, we have switched to use data loggers to trace the raw signals and then process these raw trace files and extract the binary information from them using some scripts. Nevertheless, the "core data" (32 or 45 bytes) can be read out using many SPI programmers as well.

Here are a few more threads (in German) which provide more in-deep information on the electrical interface, lens protocols, lens data and emulators:

Yes.

Hi Matthias,

I've made a lens contact connector, using a female bayonet from a low-priced macro tube kit , then I've wired the serial interface circuit for PonyProg (with SS to transistor and pull-up on transistor collector to positive supply ) and then I made some ROM dumps from Minolta lenses.
As described in this forum (the old thread), I've used PonyProg with settings for Serial EEprom, type 25080: done calibration and choosed to reverse data input to have "00" instead of "FF" in memory dump file.
I've first used my Sony Vaio notebook with an USB to serial adapter, but, while PonyProg correctly works with windows API I/O selected, data reading is slow, slow, frustrating slow (exactly as described in PonyProg manual), so I've resumed an old '486DX2-50 notebook with Windows 95 and a "real" RS232 port and all has gone better.
I've switched to IcProg instead of PonyProg because with IcProg 1.06 you can copy and past data directly from data window, while with PonyProg not and you have to save to a file first, resulting in time wasting. JDM prog is right hardware setting to use the same interface as PonyProg.
Choosing 25080 as device in IcProg results in double-byte displayng of data content location (that is "0000" or "FFFF" for each addressable location , instead of "00" or "FF" for PonyProg), but data on the same dump are identical if you suppress the most significative two zeroes.
Checksum of the entire dump do not correspond betweem the two softwares, but this is probabilly due to a diverse computing algorithm.
Sice here all ok, but now the bad news: I've tried to dump data from some Minolta lenses and I cannot compare them to forum's ones because of structure is not the same and I don't know where I'm going wrong.
A leading "FF" followed by a "80" or a "81" is what I hope to see, but this data don't comes out from lenses.....
Again I can see a 32 Bytes pattern refrain from first chip addressable location until all locations are filled, but in one test I've seen a 64 bytes pattern. Bytes count includes the locations filled with "00" until pattern repetition occurs.
Furthermore data extraction is possible from an eight-contact 28-80/4-5.6 Xi zoom, but from eight contacts "D" lenses I obtain all "00" (tried 28-80 and 28-100 "D" kit lenses and 17-35/2.8-4 (D)).

Here the dump from my 35-105/3.5-4.5 old (Beercan-like with Macro switch):

Bytes changing are the ones in positions 2,6,10,11 and 14 , starting from the leading "0A" as position 1.
Byte in position 9 changes only entering "Macro" mode, last four bytes are unchanged across all zoom range.

Note that focal lenght indicated as 35_105_55mm   is extimated by me, the (e.g.) E240 is IcProg checksum and 50f4.00 is from Exif.
I've first made a dump everytime the data changed, then I've mounted the lens on the camera (Dynax 7D) and taken a picture at every step.
I've also reported when maximum aperture reduces with focal lenght.

Can you explain me why I don't see the leading "FF" and the subsequential "80" or "81" bytes in my dump ?
A special data formatting is required ?

Here is the dump of my 24-85/3.5-4.5 RS zoom:

This time the pattern is composed of 64 Bytes, then refrains.
Bytes that changes are in position 2,6,21,22,32,34,35,36.
No leading "FF" too.

This is the dump from my Minolta 50/1.4 old (no RS):

50mm   (1.4)   D4C0

0A 00 90 FF 0C 9C 28 00 DF 02 7F 00 00 E2 0F 95
00 00 00 00 00 00 00 00 00 00 00 00 A8 26 01 88

For all lens I see "0A" as leading byte instead of "FF": can you suggest me how to make data format compatible with forum's one ?
I've see PERL script, but I don't know that programming language: please
tell me how I can do, if necessary, a manual data reformatting.
If you have an aperture table (aperture vs. Hex) and a focal lenght one (mm. vs. Hex), please post it.

PS: I'm Italian, I know a little English, but not German, so I must translate from the others forums with Bing or other translators, with some cryptic results....

Bye.

Hi to all Sony/Minolta lens data hackers....

After a long reading of the "dark side" of this thread ( that is the german discussion about this argument ) and some tries to understand what the decoding Perl script does over lens data dump, I'm finally aligned with forum's data streams.

For those who want to try recover data from lenses, I suggest to build a different hardware interface between serial pc RS232 port and the lens under investigation, to avoid possible damage to the elctronics inside the lens itself: RS232 signals range is between -3 and -20 volts for the logic "1" and between +3 and +20 volts for logic "0", but usually voltage don't exceed -12/+12 volts por desktops pc ports and -9/+9 volts for portable devices. Lense's signals range is 0 volts for the logic "0" and +5 volts for the "1" logic, but 3,3 volts are supplied to the lens when camera enters stand-by mode.
Using the interface suggested by "PonyProg" help and in this forum brings to work with lens MISO directly connected to a RS232 pin, that may have pull-ups or pull-downs supplied to pc port from/to -12/+12 volts sources, and this may be dangerous for lens electronics that is intended to work between 0 and +5 volts. !SS and SCK are protected by 5,1 Volts zeners and 4,7 kOmhs resistors, but voltage limitation is efective only for positive RS232 signals, but when they go into negative field (e.g.: -12 Volts) zeners are no long working and the only protection is the resistor.

I suggest an other HW RS232 to lens interface, bitly more complex, but electically safe, derived by me from the original, that is this one:










I've done lens data dump with PonyProg (or ICPROG )from "D" lenses and from an adaptor's (chinese) chip, where the previous (PonyProg) hardware failed (no data, all 00's or FF's). The only thing to remember is that interface settings require to invert signals to work.

Bye.

....

with the updated hardware, now lens data dump is more easy and reliable:
looking at 25LC080 EEPROM datasheet, one can see that memory serial chip requires three bytes of configuration before been clocked for data read: first byte is a configuration one ( that presets chip for reading, writing, erasing, etc. ), second and third one are a 16-bit adress to start reading or writing operation from.
Emulate lens as this kind of EEPROM make first 3 bytes invisible, because PonyProg (or IcProg) masks them (not display them) as pure protocol data, but for lens are valid data... So one must apply an offset of 30 bytes to a 32 bytes data stream and add a leading "FF" to have a pure lens data stream.

During data serialization/deserialization to obtain parallel Bytes grouping (e.g.: data in octets of bits, that is "byte" organized) single bits from EEPROM's data out have to be inverted, so if you read

0A 00 78 88 F8 4C 34 00 DF 96 6F 00 00 66 00 63     Memory dump 25080
00 00 00 00 00 00 00 00 00 00 00 00 A3 C6 01 64     mode

0A 00 78 88 F8 4C 34 00 DF 96 6F 00 00 66 00 63      
00 00 00 00 00 00 00 00 00 00 00 00 A3 C6 01 64     

......... (and so on to 1024 Bytes of the 1024x8 EEPROM )

01 64 0A 00 78 88 F8 4C 34 00 DF 96 6F 00 00 66     Reading from 1F
00 63 00 00 00 00 00 00 00 00 00 00 00 00 A3 C6     (offset 30 dec)


10 46 A0 00 87 88 8F C4 43 00 FD 69 F6 00 00 66    Inverting nibbles
00 36 00 00 00 00 00 00 00 00 00 00 00 00 3A 6C

80 26 50 00 17 11 1F 32 2C 00 FB 69 F6 00 00 66    Inverting bits
00 C6 00 00 00 00 00 00 00 00 00 00 00 00 C5 63    (D0_D7 to D7_D0)

.... and you have obtain the right data stream to work on, as the Perl script can do for you. Remember to add a leading "FF" to complete lens to camera communication protocol.

So, if you want to compare data of the lens I've posted a bit of time ago, these are the correct dumps:
