    obviously the F2.8 is going to take sharper shots, but anyone have any comparison shots between the two lenses?

    i happen to be in some darker-light situations rather often, and wonder if i wouldn't be much better off with the F2.8.

    hmm

    so, would someone get the 2.8 just because of lower-light capability?

    i'm not even that great of a photographer, but if the 2.8 is 'leaps & bounds" better, i'd rather save up the extra coin & get that over the F4

    Actually, the f/4 non-IS is the sharpest of the range. Just because something is more expensive doesn't automatically mean it takes sharper images. :ugh:

    seriously, the differences between f/4 and f/2.8 are so marginal it comes down to this: do you need f2.8, or can you get away with f/4.

    so for that extra..what is it now, like $500, ---one stop--- or in other words, less DOP and lower light capability.

    buy whichever you can afford...unless you need that extra stop...then start saving

    I shot NCAA D1 sports for many years with both lenses. The only difference is the aperture and the 2.8 may focus quicker as it gets more light to the AF sensor. You will not be able to decipher between the two.

    I should have said that the f/4 is technically the sharpest, if what you like to photograph is bench test charts. The real world difference is negligible at best. :o

    i guess i realize that, but i suppose i need to figure out if having that extra stop for lower-light is worth the extra bling.

    been reading some reviews on b&h's site, and obviously they're saying "the 2.8 is the BEST LENS ALIIIIIIIIIIIIIVE", but how much "better" is it (for what i need), is what i need to figure out, i guess.

    i'll probably just scoop up the f4 and then upgrade later if necessary

    I have owned the 70-200mm f4L, the 70-200mm f2.8L, and now have the 70-200mm f2.8L IS and any time I upgraded I never lost money on selling the previous lens; that is the beauty of L glass. So I would not take your first L-telezoom purchase too seriously. If it doesn't work, get the 2.8.

    When do you really need the IS? I'm debating the same thing get the f4 or save up a little longer and get the f2.8

    I have a 70-200 f4. I want a 100-400. I would not consider anything else. :o

    yea, sharpness should definitely not be a concern when comparing the canon 70-200s

    low light with a big telephoto zoom? you'd probably want the 2.8 IS but you're better off with a smaller, lighter prime, something that is ~ 2 stops faster. f/2.8 isn't all that great for low light shots unless you like shooting at 1600 or 3200.

    buy the best thing you can afford. I always prefer faster lenses for several reasons 1) more background blur of out of focus area, 2) faster AF (generally speaking, all things being equal), generally sharper (ie a 2.8 will be sharper at 4.0 than a 4.0 lens at 4.0).

    Automotive; IS mode 2 is amazing. Who needs a $2k Kenyon gyro shooting exotics from a helicopter when you have IS. Well, the gyro helps too, but still...that is the ONLY reason I use it. I don't take pictures of stuff sitting still very often unless I am doing models with strobes so the tripod-substitute doesn't work for me.

    I highly doubt you can see a "no question" difference in sharpness between the two. You are probably mistaking a differing DOF. Shoot a page out of a book wide open and then compare.
