Corner smear seems evident, what are the odds that ALL his lenses are not resolving the corners well, on a crop sensor? None, I\'d say.
I think there is a fairly good chance that user error/ inexperience is to blame. If that is the case, then it would make sense that ALL lenses are showing soft focus. This user did not even know how to magnify the EVF view early on to focus the adapted lenses. Who knows what other errors he might be making. The fact that there is no color vignetting is encouraging. I would think that detail smearing would be accompanied with major vignetting and or color issues in the corners and I don\'t see that in these shots. I think we need more examples from more users.
I am sorry Tariq, but I think that is just wishful thinking.
Both the CV15 and the CV12 are near impossible to miss focus with at those kind of shots.
I have the CV15, so I know that racking focus between just short of 3m and infinity makes very little difference IRL on both the GXR and NEX5N and the lens simply does not perform like that.
Racking the lens out to infinity or 3m on the GXR gives much better results even at f4.5. Especially the stopped down shots show no substantial improvement on the X Pro 1 shots. One does not even have to resort to magnified view focusing with that lens for that type of shot.
One recent afternoon I brought the GXR and 15mm in lieu of my AF A12/18 (28) to work for job site documentation and being very tired I forgot to adjust focus on the first three/four shots which were at wide open and infinity, subject was around 4m away, all looked good in spite of that. I adjusted focus to around 2.5m for some shots and actually forgot to refocus for some more distant shots and shot at wide open (colleague was at the door wanting to call it a day) and even those shots turned out just fine. So, I bracketed very amateurishly by placing focus all over the place and all shots were in the range of very good to excellent with better corners than what I have seen so far with the same lens in plain day and stopped down. A 15mm lens is that easy to make do with. With a 12mm f5.6? Haven\'t tried but it can\'t be worse.
If he has focused by simply racking out to infinity, the shots should look better. If he has racked the lens out to 2m the shots would look better. I am sure he did not focus at 1m, at which point some of the shots would still look better / more uniform stopped down that much.
Again, not nailing any of those shots, and not even the stopped down ones, points to the sensor not adequate for that lens and sensor combination. (If he could not focus the 35/1.2 at such an object, he needs an AF camera.) The more samples I see the easier it is to see the real deal with the X Pro 1, which is; excellent camera within its own lens range, possibly excellent with normal and telephoto M lenses.
