I second the request for a comparison with the 50 1.4. If someone has both and can help with this, I for one would appreciate it. I'm making a buying decision and at four or five times the price, that would be valuable information. Thanks.
I was looking at madmax200s box shots for sharpness in another thread, and while I did see some similar variation like what he saw earlier...I also think that the variation may come from AF error...either by lens design or calibration of a particular lens or sample variation.
What I found with my particular copy of the lens is that it seems to focus more consistently using multi-point AF, rather than trying to use single center point AF.
PLEASE understand, I am not refuting or challenging Madmax200s results....only showing what I came up with doing a similar process. We are all in a learning and exploration process here.
I also own an 85L, and took a reference photo with it at f/1.2. My 85L and my 50L are much closer to being the same than Madmax200s..
OK, here's the new gallery....
Photos are the 50L from f/1.2 to f/4, and then an 85L reference shot at f/1.2.
As you can see my results are slightly different than madmax200s...but I am at a loss to know why.
By the way, I sharpen my RAW shots during processing using C1 with a threshold of 1 and level of 90.
Gary, I highly appreciate your efforts but I think your earlier test shot subjects were more useful than these box shots, because of the diversity of details in the earlier ones. Were the bottles actually from your living room?
Gary, I just took a look at your gallery and your images do look much sharper then madmax's (of course you applied sharpening. BTW, do you have any shots without any sharpening? Also, your copy seems to control CA much better. Maybe it was just the way the boxes or light sources were placed.
Thanks for posting those BTW. It's a good way to make comparisons!

The first pictures were very good but the pictures of the box are extremely important for sharpness and focus assessment. This is especially in the light of previous box pictures tests. Everyone knows how the letters on the box should look like (we all have those boxes)

I saw both sets of box pictures, and of course Gary's were much better. But anything with more detail makes the evaluation easier, i.e. instead of tiny differences of almost perfect, relatively large letters, images with smaller details are easier to interprete - well, to me at least.
More great test shots Gary, thanks. I have been excited as others obviously have for the distribution of this lens. As a noob I cannot justify the 1.5k for this lens, I am hoping that the lens performance justifys the upgrade for others on this site so I may be able to find a good used f1.4. It appears it does. Again thanks. Tom
