After four months of frustration, I finally figured out why my images off 24-70L was soft. I made a bad assumption awhile ago, thinking that full-resolution @ fine quality would yield "pretty good" images. I thought the overhead of shooting RAW (i.e. post processing) is probably not worthwhile.
In addition, I opted to use the "Faithful" picture style mode, as the manual indicated that it will result in images closest to the actual (RAW?) image. (said "0" sharpening)
Well, I was wrong!
I took some "battery test" shots a few weeks back, in both RAW and JPEG fine. Looking at the JPEG images, I was quite displeased about the 100% crops. Texts were blurred and things were just soft all over. But this time, for whatever the reason, I decided to take a peep at the RAW versions, and voila - those same images were VERY SHARP!
I feel pretty silly to have been blaming my lens for the poor image quality; I just didn't expect that the quality of 30D's RAW->JPEG conversion would ever be that low. I then switched to "Standard" (i.e. some sharpening), then JPEGs looked better, but still no comparison to the RAW versions.
Lesson learned: When Canon says Picture _STYLE_, something else must be going on aside from Faithful not having any sharpening. If you look at 100% crops, they're definitely more blurry. Always shoot in RAW!
I thought I was being all smart by changing the Picture Style setting, and also "saving time" by shooting in JPEG. This will go down as one of the dumbest things that I've ever done in my life. I thought I'd share my experience with you all, in case there are others out there wondering why their images are so soft!
