Anyone else shooting Mamiya 645 lenses on the Sony?
I've found the 80mm f1.9 to be absolutely amazing!
Focus peaking means it's not a problem shooting manual either.
It comes out a little flat in Raw but a tad play about in lightroom the images comes up trumps.

Yes, the 80/1.9 is quite amazing... better 1/2 stop closed though. Right there the with Mino 85. The 55/2.8 is good for tilt/shift too, but not necessarily anything better than Mino 50/1.4 at 2.8. Astonishingly, the 150/2.8 APO is every bit as notable as the Mino 200/2.8 APO. I was very surprised to see that... and it works for T/S adapter too. Well made lenses that have the same styling as Minolta second generation MD... with the Yellow and White lettering, instead of Green and White. Actually feel as though they are part of the same system. I've not been too impressed with the Mammy wides though. But I've heard others rave about them. Could be some wild sample variations. I stick with the N's.

The OOFA is very mature on the 80 and 150. Nice shots by the way.

Oh and BTW... the 80/1.9, being 67mm filter ring, works perfectly with Sunpack DX12R ring flash. Much better than the Minolta 85. Although the Minolta can fit, the Mammy focus ring is way better to work a ringflash with.

Yeah they look really nice. I've been wondering about this myself. Wouldn't mind an 80 for my NEX-5.

Yes, I find the Mamiya 645 150mm f2.8 A is superb.

With my A77 and focus peaking, using its smooth focus ring is a pleasure.

The Mamiya 645 300mm f5.6 ULD is also very good but in my tests not quite up there with the 150mm f2.8

I recommend the Fotodiox Pro 645 to Sony Alpha adapter.

Beware that the newer Mamiya 645 "AF" lenses usually do not have an aperture ring, so you have no practical way of stopping the aperture down.

P.S. I have just started exploring the Mamiya RB67 / RZ67 APO lenses
which do not have a built-in focusing helicoid - but that is another thread another day....

All the best,
Terry

Hi,
In principle and in test use, yes!

This is still a work in progress and I haven't deployed the epoxy glue yet,
but I am in the process of constructing an adapter using:
+ the shell of an RB67 Extension Tube #1 45mm
+ a 25-55mm Chinese focusing helicoid from *bay
(which has M52 female thread at front and M42 male thread at rear;
+ an M42 to Sony Alpha adapter.

Hint #1: With a focusing helicoid starting at 25mm you have to position the helicoid a few mm into the back of the Extension Tube #1 shell to have infinity focus.

Hint #2: If I started again I would probably look at using the shorter SB (Short Barrel) Lens Spacer (nominally RZ67 only??) at the front of the adapter rather than the Extension Tube #1.

I have also noticed very recently on Amazon a new Fotodiox Pro Mamiya RB67 Adapter/Focusing Barrel listed for some of the dSLR brands (not Sony Alpha yet, AFAIK).

All the best,
Terry

P.S. For me the two factors that make this effort really worthwhile are:
+ the high quality/reasonable price of the Mamiya RB67/RZ67 APO lenses;
+ focus peaking on the A77 and its relatives.

All the best,
Terry

acemclynch: both your portraits are excellent!

photosopher/terryg: would you mind posting somewhere a few pictures using the mamiya 150 APO please? I'm quite curious as to know how it looks for portraits on a FF camera.

Hi,
Not FF, but here are two sample pics I took handheld with the A77 and Mamiya 645 150mm f2.8 A at a local church Christmas Carols event.

This was a twilight event, so the lighting in the first one was a mixture of the twilight and floodlights from the building.

The second pic was nearly all from the floodlights.

No flash used in either.
Both photos are slightly cropped and lightly processed in Lightroom from Raw.

In these conditions this is NOT a sharpness test for the lens,
however I thought the lens' rendering appealing, the skin tonings good and realistic and the out of focus areas very smooth.

I used this lens for nearly the whole event and enjoyed the results.


#1 Mamiya 645 150mm f2.8 A on A77 at 400ISO f4 1/80 sec


#2 Mamiya 645 150mm f2.8 A on A77 at 2000ISO f2.8 1/100 sec


All the best,
Terry

Which is exactly what we'd want from a portrait lens I think!

Thanks for the input!

(now... how long till I put one on order )

keh.com in the US has a Mamiya 645 150mm f2.8 A in "EX" condition at a reasonable price at the moment!

Was curious about thoughts about Mamiya "C" vs. "N" lenses.
The "N" 150s I've seen are 3.5 and the "C" 150s I've seen are 2.8.
Web browsing revealed N lenses supposedly have better coatings but are plastic.
Since its on the Internet it must be true right?






Practice makes more frustration

Hi,

Mamiya sometimes indulged in a bit of alphabet soup.

I don't claim to be a Mamiya 645 expert but will give you a summary of my understanding of things.

Talking about the Mamiya 645 manual-focus lenses,
which are the ones easily adaptable to Sony Alpha
with the Fotodiox Pro adapter or equivalent adapter:

+ 645 N's are newer than 645 C's;

+ N's are reported to have better coatings for more contrast;
Most people prefer N's for the better coatings;
some people may prefer the lower contrast of C's for portrait work etc;

+ For some focal lengths, especially at the wide angle end,
the N's are reported to have a revised/better optical formulation than the C's.
The extent of these changes is debated.

+ N's will often still have a C on them as well,
for example markings such as "MAMIYA-SEKOR C N"

+ N's are still mainly glass and metal and very solid ,although they do usually have some plastic for aperture ring and focus ring cover.
N's are definitely not "plastic" overall.

+ Some of the relatively newer lenses do not have either N or C on them,
for example my 150mm f2.8 is marked "Mamiya A"
The A indicates the use of special glass such as anomalous dispersion glass and maybe that the lens is Apo-ish.

+ My personal 2 cents worth is that I have N's except where I have bought/want A's or APO's.
In the case of the 300mm f5.6 I bought the best-rated version, which is labelled "C ULD N".

+ On your specific question, AFAIK in the Mamiya 645 150mm f3.5 there are both "C" and "N" versions.
For the 645 mount I doubt that you saw a true 645 150mm f2.8 C
- that may have been for one of the other Mamiya mounts.
In Mamiya 645 mount I believe the 150mm f2.8 was normally labelled "Mamiya A" like mine.
That is the lens which photosopher and I were raving about earlier.

+ This summary does not cover all the variations of the Mamiya 645 alphabet soup.

Apologies in advance if my summary has offended any Mamiya 645 gurus out there.

All the best,
Terry
