Maybe it's time to switch to Nikon or Sony...
No maybe about it. Canon sucks. As we all know, the sensor is of paramount importance - the other aspects of camera performance, not to mention the lenses, are irrelevant. TonyY, sell your piece-o-crap 5DII and your eight L lenses and switch. Please. Your repeated posts about Canon's exceptional inferiority will be sorely missed, but we'll all manage to get through, somehow.
Too late for me to switch as a hobbyist, but ppl has not heavily invested in Canon needs to know some of the facts. You don't know how it felt when my friend's Sony Nex 5N + 30yr old Carl Zeiss outperformed my 5DII + TSE24II.
I'd like to see the methodology and numbers for that test! The TS-E 24mm L II is one of the sharpest lenses on earth, and even pitted against a Carl Zeiss lens, I'd expect it to outperform. No more anecdotes when you make a claim like that. You need to produce some actual results, and the methodology used to achieve those results.
Subjective "Well he liked the results more with the Nex/Zeiss combo." a scientific analysis makes not. ;P
So here it is: 5DII + TSE 24II (IMG_6396.jpg) vs. Sony Nex 5N + Contax 28/2.8 + adapter (DSC06395.jpg) -- see attached images I took mins ago.
Not a scientific test, it is not a fair test due to the sensor format, focal length (I have to walk half way closer to include the same scene/view)... So, just take look at the center resolution of the image. Don't get me wrong, TSE 24II is a terrific lens, just the 5DII sensor can't handle it.
Setup: tripod, not filter, f/5.6, iso 100, picture style "standard", manual focus using live view and in camera jpg (don't want to involve desktop software, but need to reduce the attachment size under 2 mb)
