Anyway, thanks for dong this comparison as it confirms what I thought that they are all very close with the Z* winning by a very slight amount.
If you're talking about the last comparison, which one is that according to you? Lotusm50 said the lenses are not necessarily in the order that he mentioned them.
I don't see a significant difference in these last 3 shots (except the 3rd one being a bit darker). It's really splitting hairs...
Lotus, in both cases, I have a clear preference for N°2. In the fist set, I find N°3 almost as good as 2 and much better than 1. In the second set, I find the differences slighter, and 3 and 1 are comparable, with 2 slightly ahead.
Thanks for taking the time and trouble to do these. It is much appreciated!
What strikes me about the responses here is that we don't get a reason for a preference, if one is expressed. Wayne and Aham both indicated that they are all very close. I could not agree more. Outside of perhaps a slight exposure difference ("a bit darker"), they are virtually identical. I think anyone would be hard pressed to give a defensible reason for preferring one over the other - not in terms of sharpness, contrast, rendering, or "pop" (the claimed difference in "pop" being the reason for the comparison) that could possibly be perceived in these samples. Philber, kindred spirit that you are, I just don't understand how you could "clearly" prefer one of these samples over the others.
I am referring here mostly to the second set of the images. The slightly different focus point in the first set makes a difference in how the images appear. Even though the focus distance in them is off my a few millimeters, and then stopped down 3 stops, the differences in focus is apparent (even in the reduced jpg) and now covered by DOF. It makes them look different for reasons unrelated to lens performance. So, we have disregarded them for this comparison. Knowing how difficult it is to manually focus even bright f1.4 lenses with a AF-oriented DSLR (even with the EE-s screen), so many of the comparisons we see (unless done with live-view to confirm focus and the accurate focus achieved is demonstrated in the comparison) most of the home-brew tests trumpeted here and elsewhere are just unreliable and untrustworthy.
There is one clear difference between the 3 images and I am surprised no one mentioned it. It's apparent in both sets of images. The first image in each set is noticeably warmer in tone than the other 2. I think this small difference can be compensated for in post processing. Thinking out loud, I am wondering if this makes a difference in the perception of contrast and sharpness between the samples. Colder colors are often perceived as crisper, which could lead to a judgment about contrast/sharpness.
If I get time and a dose of motivation, I'll re-do a closer focus sample set -- this time ensuring I get the same focus point on each, and perhaps adding some color objects. We'll see.
