EOS Bodies / Re: 46mp sensor useless for landscape?

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)
SUBJECTIVE!! "Just take a look at the center resolution of the image"?!? What the hell kind of comparison is that!?! That's exactly what I said NOT to do!
BTW, something is seriously up with those photos. The Nex seems to have captured trees in the background that simply don't exist in the Canon shot. Unless your trying to tell me the Sony NEX is capable of generating content that isn't there, an that that is its strength, I find this "test" 100% bogus. All your doing is saying:
"Well, the NEX image looks better to me!"
Sorry, you can't objectively determine if either of those photos is "better", too many variables (pixel size, focal length, camera settings, etc. etc.), not the least of which is the fact that you manually focused, which adds a huge human element of non-deterministic subjectivity to the test right from the get-go. If you were using contrast-detection AF in live view, or had a proper test chart to help you gauge when the image was well and truly focused, that's a different thing...but this....
BO-GUS.
Calm down, this is just a simple test, comparing the combo/image not the camera itself, I think I did the best I can. 100% live view manual focus is more accurate than auto focus, what you see is what sensor captures. Focus are both on the tile above the house at center. Since Nex sensor is 1.5 crop and focal length is 28 vs. 24 =>(1.75) the 5D II shot took is half way closer, that's why perspective changed, some of the tree appeared/disappeared.
Maybe it's the in camera software (standard jpg style in both), to me the Nex image looks has better contrast and bit sharper even it is 1/3 overexposed than 5DII.
