I have not yet tested a ZD myself (though I expect to get one for testing in the next few weeks, as there is now a Canadian distributor). So, I can't comment about its image quality, yet.

Michael,

When you test the ZD, be sure to convert the RAW files with either Raw Developper or Silkypix.

Other options like the Mamiya software of Lightroom are OK, but don't do fully justice to the potential of the sensor.

Bernard

I'm using a 1DsmkII and Pentax 67. Mostly the 1DsmkII. I'm thinink of moving to MF, not that I've had any problems with the Canon, it's very versatile and handles very well.

Hi Kevin,

thanks for the info

I made today some helicopter shots with the 5D and 24-70L. I'm not so satisfied you need 1/500 - 8 otherwise the edges are not sharp. better would be 11 but for that it was not enough light.

Thomas,

This is why I am considering MF, the wide angle situation often requires stopping down a lot. The Canon 17-40mm does not get sharp across the frame until f10. I'm also using a Sigma 12-24, much better than the 17-40mm  for distortion but it still needs f8. The good think about the Canon is you can shoot at 400iso, the digital noise is nothing like film grain would of been at 400iso. The problem is with MF I can't shoot wide at 12mm or have stabilised lenses at 200mm plus. So even if I do jump for a Phaseone etc the Canon will be far from retired.
The 70-200 f2.8 stopped down a little is very sharp, the 50mm f1.4 needs about f4.
On a different note, I use Aperture mostly and Bibble also Photoshop but for sharpness Canon's own DPP gives me something I can't get with any other converters.
I also use a program called Focusfixer [a href=\"http://www.fixerlabs.com/New_Website/pages/focusfixer.htm]http://www.fixerlabs.com/New_Website/pages/focusfixer.htm[/url] I find it adds a natural bite to images.
Here's a sample of the range of images I do, everything from 17 -200mm http://homepage.mac.com/kevin_allen/Test%20Album/index.html

Hope this might help,
Regards,

Kevin.

The big negative for me is the fact that you can only use Mamiya lenses with it
[a href=\"index.php?act=findpost&pid=105045\"][{POST_SNAPBACK}][/a]


On my ZD I also use (the very nice) schneider kreuznach and zeiss jena lenses (both p6 mount). For 100mm and up you can get a zörk adapter with tilt and shift that uses the schneider and rodenstock LF and enlagerlenses, wich are very good too.
To bad that there is no wider shiftlens - or any wider lens at all of good quality. I have not seen the promised 28mm mamiya lens appear (and one dealer told me that he doesnt expect to see it this year).  
I think for some types of work, the ZD is very good to perfect (but certainly not for fast-shooters). For my work I find the ZD very suitable, shooting interiors and mostly using the lenses  nearly wide open. the focus-confirmation light in the ZD  helps a lot to nail the focus even with the 1.9/80mm. Any of the alpha, cambo-wide et al would be of no use here.
The dynamic range and the ability to retain highlight-detail are phantastic - and so are the colors.

the mamiya software is useless for converting images - but fine for thethered-shooting, as it always get´s the white balance right, which is important if clients look over your shoulder ( and I dont like to explain to the client that  "yes, the pic is green, but it wont be like that in the final picture" all the time).

the only thing about the ZD  that realy bothers me, is the fragil firewire-connection.
another plus: I have never seen an error-message on the ZD.

Stefan, thanks for valuable information!
An off-topic question: have you tried using 8GB CF card on ZD? I was planing to buy Sandisk IV, but am not sure it ZD will recognise 8GB. Thanks,

I am afraid, I don´t know. I have only used the ZD tethered so far. If you find out, could you post your results?

I have tested Mamiya ZD with 8GB CF card. ZD will save 229 RAW images on 8GB.
