We've had these MFD vs 35mm arguments for far too long.
Hi Sandeep,
You are suggesting that the differences are static, non-changing, but new sensor generations in general improve over older ones. So, yesterday's opinion may differ from today's, and today's may differ from tomorrow's. Therefore the discussion will not stop, as long as technology develops.
To be honest, I have no illusions that either camp will change their opinion ever.
That's an odd position. I for one, am not in a camp, but will judge based on the presented evidence and on how well the equipment is suited for the purpose.
But if we are to debate endlessly, might as well do it based on some images and not yet another graph.
As long as the images are somewhat comparable. Graphs and charts will allow a more objective judgment with fewer variables to consider.
Below are three images shot on the same day. Same studio, same lights, same model. Two are with 35mm full frame cameras. One is with an MFDB.
They are reasonably close, close enough for comparison, but the Raw conversion process will always benefit one over the other, depending on what one is looking at. Some camera profiles are better than others for certain subjects (which is why a number of people say they prefer Leaf backs for portraits / skin color). Both Leaf and PhaseOne backs use the same basic (CCD) sensor technology, yet some prefer Leaf for one type of subject, and PhaseOne for another type.
With that out of the way, A = MFDB, B and C are 35mm FF cameras (B is possibly a Canon, C is possibly a Nikon).
That is based on the aliasing character of A, and the sharpening Halo on B and C.
There is some difference in the color rendering, but that may (besides camera profile) also be caused by moving colored objects/surfaces/clothing close to the camera that seems to reflect some green on the subject. We have to assume that the flash emitted a constant color temperature, because changing the output power could introduce a slight shift in colorbalance, which could require a different correction in the Raw conversion process.
The highlights of A are a bit too desaturated for my taste, and the overall bias is more orange than yellow, which is apparently considered more pleasing with Asian types of skin color, or so I'm told.
The colors of B are slightly greener in the shadows, and the skintone in C looks desaturated (maybe Raw compression and noise reduction also caused a bit more smoothing, although that may also be due to CaptureOne's Detail settings for the specific camera model).
So for me the differences are mostly color mapping related, B needing a bit less green, and the others needing less desaturation. Of course, this is only going to jump out in a direct side by side comparision. The highlight roll-off is a function of tonecurve, and can be adjusted to taste.
Cheers,
Bart
