100% crops.
Both lenses on 5D mark II, 200mm, manual focus on "15", tripod, MLU, default LR 2.6 sharpening.
The f/2.8 has been rotated a few degrees to match the f/4.

get back to us when you can get a shot taken with the 70-200 f4 ISL taken at f2.8

oh wait..it can't take a shot at f2.8

and THIS is the reason why people buy the f2.8 version of this lens.

the f4 IS lens is sharper?? give me a break...because at f4, the 70-200 f2.8 wipes the floor with it every time.

if you don't need f2.8 then the 70-200 f4 IS L is a great alternative.

yeah if if if... i thought i already addressed that :D?

But I keep reading posts, not from you, but others that seems to be clueless of the difference between f/4 and f/2.8 and think that sharpness is more important than aperture.

I have shot with the f2.8L for 3 yrs now and would love to be able to shot with the smaller, lighter f4L. However, 90% of my shots are in low light (ISO 1600, f2.8, 1/320s) indoor sports and I could go to the f4 lens at ISO 3200 but the slight (depending on who you talk to) increase in IQ cannot come close to offsetting the decrease due to the bump in ISO. The f2.8L is a great lens on the 50D... the 1.6x crop, 15Mp, and great ISO 1600 performance are perfact for indoor court sports and dance/cheer competitions.

Yeah, it seems that the f4 is a great lens for shooting charts.
Too bad I don't shoot charts ;)

Those who have the 2.8 versions should trade with those that have the 4.0 versions.
That way we all have reason to be really upset:p

thanks. does anyone else have some pics they can share to illustrate the DOF/bokeh differences between 2.8 and 4.0. I want to see how big a difference that 2.8 will make for some portrait shots... THat's the only reason I would want to upgrade to the 2.8. I've been using the 4.0 this weekend, and i love it so far.. a little long for indoors, but IQ is great.

I think i opened up a can of worms with this thread but i agree 110% with your comment. I'm buying one on thursday just not sure which one

rijndael wrote in post #9251060 (external link)
Thanks. I'm trying to decide between the two. I'm not overly concerned about the price of the f/2.8 if I can justify the need for f/2.8 over f/4 ..... I'm not convinced yet.

Another big advantage of the 2.8 (IMO) is the ability to use teleconverters and still have a fairly fast lens. A nice increase in versatility and value over the f4L.

:\ They both rock. I want the f4/L IS because it's a lot smaller and it'd be a lot more convenient to take with me. The 2.8 would be nice but I doubt I'd use it as much. I think it's just like...do you need f2.8? If so get that one. If not get the F4? The f2.8 version has a large advantage: f2.8. However the f4 has a large advantage too: size and weight.

Pick one. It's not a matter of better. It's what matters more to you.

How significant are the AF differences between the 4.0 and 2.8 70-200 families? I shoot enough sports for that to be a consideration.

Thanks.

In my opinion when you buy a Canon 70-200 don't worry about sharpness they are all VERY sharp at comparable apertures, just the 2.8 if you need that extra stop, and then add IS to the one you picked if you need it.
