I have read here:

The 70-200 f2.8L zoom is not as sharp at the corners than the 75-300 IS at 75-170mm? Can this be true? Look at the conclusion at the end of the article to see what I mean.

I am in the process of buying a 70-200 f4L, after selling my 75-300 IS, as the 75-300 IS was not sharp enough for me.

Any advice would be appreciated!

The 70-200 F4L will blow the 75-300 IS out of the water in terms of sharpness (camera shake aside). You won't be disappointed.

i've read the conclusion, and nowhere does it say what you're saying...

as to advice? i think you should sell all your gear and go nikon!

The 70-200/4L is a beautifully sharp lens. Yes, it will blow the socks of the 75-300 IS. I absolutely love my 4L. It is super sharp, light, compact, has excellent build quality, with fast and silent autofocus.

I bought the EF70-200 4L USM last Fall because I was disappointed with the performance of the EF75-300 4.0-5.6 IS USM (I still own them both). The IS feature if the 75-300 is wonderful, but it's a real bow-wow in all other ways compared to the 70-200. The build quality, ergonomics, AF speed, feel and optical quality of the 70-200 tower over the 75-300. I wrote a review of the EF70-200 4L USM if you're interested:

I'm not even going to read what was written at this site. Assuming there is a statement to the effect that the 75-300 is actually better at any point than the 70-200/2.8L, I will state without equivacation that there is a short between the brain and the keyboard of the poster. That is total BS!!!

I use my 70-200/2.8L lens with a Canon 1.4x Extender a lot. It beats the hell out of my 100-300/4.5-5.6 lens. I suppose there may be a substandard 70-200 out there and a 75-300 that is exceptional. Even considering this...it doesn't matter. Anyone who believes this is an idiot.
