Thought I'd do a little test. Same subject, same lens, same time and light conditions, both post processed in Silver Efex Pro 2, but one image was shot with the M8 and the other with the M Monochrom. Can you tell which is which?

 

Note: The MM image has been downsized to match the M8 and exif data has been removed, so this will have to be a visual.

Assuming focus accuracy, image one would me the MM. There is shallower depth of field on a full frame sensor. The flower that is in focus is sharper. I have found that the most significant differences between the MM and the M9 converted to black and white is in the actual print. The down resolution images on the computer do not make the differences as evident. Anything printed at or above 17 x 22 inches would be immediately obvious.

When you say 'processed', did you try and match contrast and black point?

 

To help me; can you post the same test, but shot at ISO 2500... thanks. :p

 

Yes, I did try to match contrast and black point. I forgot to mention, both were shot at ISO 320. I think 2500 might be a bit easier to tell apart. :)

Nope. I can't tell which is which. Perhaps, as in tasting fine wines, my palate just isn't developed enough. ;)

 

+1

 

The plane of best focus is very slightly different. Looking at the pictures again and again, looking for higher resolution (what else should we look for?), I'd also plumb for the first, but without much confidence.

The first image also has more dynamic range. But the variables in processing will result in some bias with regard to outcome. You definitely will see differences in sharpness and DR with the monochrom when processing in Lightroom and when printing.

Both images were RAW captures, converted using ACR, then taken straight into Silver Efex pro II for final adjustments.

Not going to play this game because with this picture the light and composition is not challenging enough for it to matter which is which. You would have to push the envelope of dynamic range or difficulty of light more for it to matter whether it's an M8 and a M-Monochrom.

... or our sight is more developed than a PC screen image : I have always thought that to fully appreciate a fine taking with the MM you must look at a well processed print... :cool:

Anyway, just to join the game, I tend to identify the first one as MM

The difference is infinitesimal. Absolutely no idea. As always, it really depends on your screen. Both look good side by side on the 27" iMac. Blown up to 16 x 20 prints might be different. My instant preference, marginally, was for the one on the right.

Two images taken with different crop factors, then cropped more to look similar, then post-processed differently to look similar... What kind of a test is that?

 

If you want a comparison you need to process the images identically.

 

And anywya, "tests" like this with small images posted to a website is useless.

 

I could have made a same comparison between an MM and Canon Rebel with the 1.4/50 USM and made the images look extremely identical as long as I processed them differently so that they match in look. One can even emulate the look of bokeh characteristics in Photoshop if you want...
