I am thinking whether I should move away from Hasselblad to Mamiya because of the AF issue.  Based on your experience, are Mamiya lenses (not the latest AFD ones, the older zooms) up to the task of dealing with a 39mp back?

Thanks and happy holidays to all.

He  probably meant the opposite. That the Mamiya AF is slower or something.

I'm pretty sure he means moving from the manual focus V-series to auto focus Mamiya 645.

Hi
Just did a shoot with the Aptus 75/AFDII/55-110 Zoom @ f 11-16 in the studio & the quality was excellent. BTW the Aptus 75 is a 33 mp back & competes with the Phase 39 back. If you are going to Mamiya get the AFDIII body.

AFDIII still has some firmware issues.  Prime lens freeze up but with current firmware the metering and dials seem to work much better.

Make sure you have firmware 1.4 it is a lot better . To check go to custom function 36 and it should be there. You have to send your body in for this firmware update , takes a couple days. Actually mine was done the day it arrived and shipped back same day. Major improvement in shutter lag, flash syncing , mirror up functions and several other improvements. It is a free update also

Thank you all for the replies.  I am sorry I was not clear.  I meant moving from a manual focus V-body to something with AF.  An H system would be my first choice but there are cost issues.

Yes both the 55-110 AF and 105-210 AF zooms are more than adequate for 39 MP capture, but you need to stop them down to f8 through f16 to get the best out of them.  Note also that the zooms are a bit slower to AF than the primes.

well mamiya is alive today, kind of,  because of the huge user base and used market  but the only mf system which has the potential to survive in the long run is probably hasselblad.

considering that the next generation of backs are above 50MP, a good question would be are the Mamiya lenses (non-D lenses) able to resolve that much?
I'm considering switching to a Hassy H, and if the older mamiya lenses don't benefit from the added resolution and their D lenses cost as much as a hassy, makes more sense to get a Hassy

May want to take a look at this test with the P65 Plus Jack and i tested a couple weeks ago. The D lenses did amazingly well but we did not shoot much with anything else but I know the 55mm AF is just as good as as my 80 D and 150 D and even the 28D posted did very well. http://forum.getdpi.com/forum/showthread.php?t=4333

Merry Christmas to everyone, Enjoy the day

Let me get this straight;  you have Mamiya equipment already and are considering a switch to hassy because the new glass is the same money?

The way I understand it, he is considering switching because the Hasselblad glass is better, and about the same money.

And the Phase One body focal plane shutter does 1/4000th . Pick your poison. The high sync is what some may need and the higher shutter is what others may need. Rather have the faster shutter myself. I have gotten around the high sync shutter for years and have much more need for the higher shutter speed. Horses for courses, pick what systems works best for you.

I personally would not switch systems because of the glass. I would switch or chose a system because of features , ergonomics, ISO limits, different types of lenses, T/S, software and stuff like that. Obviously if you need something one system has over the other than that would come into play and price of course. Each system does a nice job of producing results , just find one that clearly gives you as the shooter more advantages over another on how you work and what you shoot.

Hmm, I have exactly the opposite opinion. I would really have to feel forced to switch system over ISO etc., by being completely unable to get my shots done in a system, but I *would* switch systems if a different one had much better glass. I am not saying that Hasselblad has better glass than Mamiya, just that *if* it did, and I felt limited by my current system, then better glass would make me switch faster than any other factor.

Carsten in 35mm system I would feel that way but in MF i feel less inclined because of glass only. I see much more of a glass swing in 35mm than I do in MF. Interesting turnabout there

Thank you all for your replies...

Speaking of glass...I am not particularly impressed by the color produced by the phase backs on Mamiya cameras.  It could be the glass, it could be the backs, I don't know.  The color on those P65+ pics, as well on raw files given to me by a dealer for evaluation is not something to write home about.  The images are high resolution but lifeless... it could be just me.  My old Zeiss glass with a V96C back is producing much more pleasing color.  Phocus also made things better as well.  The images look as if they came out of my Canon but the resolution is 3-4 higher.  I am not as hot as using Mamiya as my AF camera...
The good lenses cost as much as Hasselblad H lenses do.
