Got from a friend of mine on facebook.
Friend: "Wat to buy....EOS 50D or EOS 5D....???"
Stranger: "Check out the 550D bro, I have one."
Friend: "i still think the 50D is a lot better...although the 550D is 18MP it falls short of 50D in terms of many features....ex: shutter speed, chromatic abrasions, continuous shooting frames, integrated cleaning system..the noise reduction level...i considered the 5D coz is sensor is full frame..n the mkII is 23.6MP"
Me: "Is it chromatic aberration you're talking about?"
Friend: "Yup, wrong spelling hah.. the lower end models are more prone to it. Thats wat the experiments show lol"
Me: " huh? is it?? 550D and 7D shares the same sensor.. so with that come in mind, you're saying that 7D has more CA?? AFAIK high MP can make CA worse but the main reason is still on the lens.. coz they dun have fluorite elements in it (fluorite is expensive in good lenses)......"
..........
Isn't chromatic aberration has something to do with the lens? As far as I know, sensor has nothing to do with CA, but MP is an exception as it will magnifies the horrible CA and thats it.
Err, no comment.
