I am a commercial photographer specializing in food advertising. I shoot national and international campaigns for well known companies. I am working with Canon, but every few months the MF bug bites me. I got burned quite heftily with the Leaf AFi, which lost me a lot of money and a few pissed off clients, still i can't get me hands off those huge cameras.

This time I did a test  comparing the Canon 1DS mk3 & 90mmTS-E with the Hasselblad H3D-50 with the HTS1,5 and the 80mm.

both lenses were tilted at their max, no shift.

The subject matter is just my groceries, but I tried to duplicate a couple of problems I am facing in daily shooting.

I am not telling how I postprocessed them, not do I care that people will moan that one cannot compare resized sRGB jpgs. I am happily and comfortably supporting me and my family with my work which nearly all end up either in CMYK on billboards or in magazines or on the web, so no one sees them in 100% on calibrateded Eizos, usually not even my clients who pay for them.

I had big troubles focussing the H. Live view is the joke we all know from MF, and with food one cannot run the model lights too high, so I got out a hotlight and lit the ceilling of my studio when I tried to focus that thing. Still the plane of focus is not equal in these shots, so beware when you compare sharpness.

Phocus is nice to work with, I just could get going without any delay, very well done. much nicer than that shitty EOS capture I am stuck with.

My server is seeing a lot of traffic recently, so I put those files (27MB) on rapidshare.

please let me know what you think, I will post the solution in a couple of days

cool, now on my large monitor it's BDF for me.
It's the monitor that matters, not the camera :-)

I voted ADE, looking at the out of focus areas, noise characteristics, and detail in the focused areas did not look like Canon files to me. All at 100% of course...

If everything is shot the same.

A = mfd, better highlight detail and out of focus area is cleaner

D = mfd better overal detail

E = mfd, This was the hardest image to see any difference. I thought the highlights looked better.

For this to be a meaningful test it would have to contain fine detail that could only be resolved by MF.

For this to be a meaningful test it would have to contain fine detail that could only be resolved by MF.

Those three setups were chosen to tackle common problems i encounter when doing my work:

A/B shows a lot of fine detail in the dirt of the mushrooms, the pepper, the wood and the napkin. certain elements in the picture need to be in focus, while others don't. how much more fine detail do you need? surface structure is extremely important in my kind of work.

C/D is aiming  shadow details and chromatic aberations

E/F goes for colors and focus, when the subject doesn't have hard edges like I encounter with fruits or soup. 


attached you see the setup

ADE for me. The colors seem more clean, the bokeh sharply more in compliance with the idea than I make of one MF. But I have maybe any forgery. I like the photo of the table-top in your last message.

My guess BDE

To me they all look very noisy and oversharpened and the levels are probably adjusted. If this quality is fine for your clients I guess you can go with either system.

IMO most of the IQ advantages are lost because of the settings/processing.

Ok, I think the main point has been made : identifying at those sizes, a 21 MP DSRL and a 50 MP MF is far from being an obvious affair, for this particular kind of subject . A good lens, good light, DOF placement possibilities and postprocessing are far more important than your choice of system (for these type of shots, at those sizes).
Anyway I would have been curious to see a comparison between the "best" of each system, for a "fuller picture" Smiley : a Hartblei 120 Makro-Planar Super-Rotator on the 1ds3 and the 100 HC with the tilt-shift adapter (it doesn't work with the 120 Macro) on the Hassy, would have (probably) made an even more interesting comparison. Oh , well Smiley ...
Anyway, hopefully the OP will now reveal the answers .... Smiley

B C E - for me. More noise, harsh bokeh, hot pixels, all attributes of digital back Grin
