    diffirent MFDB or Sony

    Dear all;

    I'm faced with issues about my ZD back, great image quality at low ISO, but with a few operational issues. I shoot mainly fine art nudes in a studio setting. Some glamor, and if I need to go outside, I use my D300.

    The ZD issues ....

    1) Top real ISO is 100, 200 in a pinch with noise reduction, but then why bother
    2) The camera is easy to out shoot, slow frame rate, and small buffer
    3) It will lock up at least once a shoot, requiring a few minutes of mucking about to fix it.

    All that said, the image quality under studio strobes ( my application ) is exceptional, and just putting up with the problems is an option. That said, I'm still looking into three alternatives:

    1) Get a Sony A850 + CZ 24-70 + CZ 135 .... This nets out to about zero additional cost assuming I sell all the Mamiya stuff at a reasonable price, and buy used for the body and lenses.

    2) Get a used P30+, fixes all the issues at around a 5-6K upgrade price. IQ will be better, but curve is so flat, and I shoot the sweet spot of the ZD that IQ would become a pixel peeping issue. Could print a bit bigger/crop a bit more, but again, the extra 8 mpix are not a slam dunk in advantages.

    3) Get a used P45+ fixes all the issues at a 10-12K upgrade price. IQ and cropping become a slam dunk.

    With that extra money not spent on a back, I could take the trip of a lifetime to West Africa (P30+), and with the money not spent on the P45+ I could bring the wife! I don't have enough cash laying around to do both.

    Any thoughts from out there in forum land? There is a thread out in this forum really praising the Sony's in terms of IQ, and that is what led me down this bunny trial.

    Thanks for the input.

    Dave

    I've owned both a ZD camera and an A900. Assuming optimal working conditions in a studio setting, is the Sony an effective substitute for the ZD?

    I don't think so. A capture made with longer lenses on a big sensor with no AA filter just has a different look-and-feel. It's a different animal. It might help to think of it as a difference in character, or a difference in "qualities", rather than a difference in "quality".

    That doesn't mean moving to the Sony would be the wrong choice for you, only that it's going to have to be a subjective judgment on your part as to how much that different look-and-feel matters to you.

    It may be worth your while to go to lensrentals.com and rent an a900 and the two lenses. I just checked and it would be about $265 for the minimum 4-day rental, including shipping. Then at least you would know exactly what to expect from going that route.
    α900+VG|F20|2xF58|16-35,24-70,135Z|STF|70-400G|50,85 1.4|16,20,28,100M,80-200APO f/2.8|28-135|500f/8|1x-3xMacro|2xMFC-1000|Tiltall+RRS, Bellows, etc.

    I think I would go the P30+ route.

    Dave,

    If you like the quality of ZD files (when it performs and produce well), I recommend you looking at Leaf Aptus 22 and Aptus 65. Leaf Aptus 22 uses the same Dalsa sensor as ZD but it was well implemented and not plaiged by the problems of ZD. Three years ago when I upgraded ZD due to the problems encountered I looked at both P30 and Aptus 22. The P30 being a Kodak sensor has a different quality. I much preferred the characater of the Dalsa sensors in Leaf (so does Phase One in newer backs ). I went with Aptus 65 because it was sligh less price than Aptus 22 at the time. Actually a used Aptus 22 was more than a new Aptus 65! Why? Aptus 65 is a 44x33mm crop sensor instead of a 48x36mm sensor. Makes much difference? Both are crops. What did make difference to me was that Aptus 65 was a newer generation sensor and same as Aptus 75, except for the sligh lesser crop factor. That meant slight higher ISO capability than Aptus 22 and slight better noise characteristics. You could also look at Aptus 75 of course. Those are nothing like ZD, they rock in image quality.

    MFDB vs. travel? Personal decisions... and what is good for business???

    Hello,

    This nets out to about zero additional cost assuming. Three years ago when I upgraded ZD due to the problems encountered I looked at both P30 and Aptus 22. The P30 being a Kodak sensor has a different quality.
