well ive been contiplating getting a new lens for about 3 months now it has come to the 100-400, 300 f/4is, and the 400 f/5.6. i already own a 70-200f/4 but would sell it to get the cash for the 100-400. i find that the 100-400 would be my best bet because it reaches every range i could ever want. i mainly shoot sports such as surfing, which i find a 300 does the job respectfully. although i would love to have the extra 100mm for the big days that roll around once in a million years. i have rented the 300 and am very happy with the rusults. i find that the quality is odly nicer than the 70-200(which is supossed to be the sharpest.) thanxs

I've shot with the 100-400 several times and been disapointed with its lack of sharpness every time. Also not being a super fast lens has its downsides. I shoot a lot of surfing myself and usually find myself in the 300-400mm range though, so yeah, tough call.

I had the 70-200 2.8L IS USM and sold that to get the 100-400 - and while it is a nice lens, it just was not as good as the 70-200 - and I used with with a 2x converter! If I could afford another, I would grab it in a NY minute!

I would never part with my 70-200 2.8L IS lens. It is the very sharp and extremely versatile (I use it for a LOT of different things).

But for shooting sports ... I now only use the 70-200 in low light.

For normal shooting, I was using the 70-200-plus-2x-extender and kept complaining about how soft the images were. I switched from that to the 100-400 4.5-5.6L lens and don't regret it one bit. I find the 100-400 lens to be very sharp. Not as sharp as the 70-200-minus-2x-extender, but definitely sharper than the 70-200-plus-2x-extender.

Take a look at these recent photos ... all shot with the 100-400 lens:

What about the 300mm + 1.4x? You'd get a 420mm f/5.6 with IS and can take of the extender when you don't need it.

I've been playing with my week and a half old 100-400mm and have been nothing but amazed in the sharpness and detail on both ends of the range. My 70-200mm 4L is going on a rebel body for the wife to use, I don't know if I'll ever use that one again.

I do have a learning curve with lighting with this thing how ever but it prolly just what I am shooting. I get into situations where I lose the subject and make this thing hunt a bit to get back on track. Again a lot of it is the way I've been shooting it and what I have been shooting.

I have thrown my Kenko Teleplus Pro 300 DG x1.4 TC on it (manual focus because it becomes a f/8) and the detail on the long end is amazing.

Now the extra 3 lbs takes a bit of getting used to in the first week.

ya, i have been thinking about getting the 70-200 and slapping a 2x's on it, but ive been hearing mixed reviews about the entire ordeal. i really would think the 70-200 would be my best bet cause i love my 70-200 f/4 and the 2.8 is amazing. i have tried it out at night and i just fell in love with it. i was shooting at like at 60th with mine and then i slamed that baby on and i was shooting mabey 160-200 varying on the location i was in. this was at a night football game at like 9pm. i was astonished. i find that, the 70-200, with the fast lower end would be my best bet as far as me shooting sports goes. well thanxs alot!!!

and dont quote me if im wrong, but if i slap and 1.4x or a 2.0x on the 70-200, it wont dissable the auto focus. correct? cause thats my biggest fear. but i think it allows af. thanxs

A 2.x on the 70-200 2.8L will cause the minimum aperture to become f/5.6 which is still within AF range.

Slapping a 2.x onto an f/4, however, makes it f/8 which won't auto focus.

Just coming from experience on this one, putting a 2x converter on the 70-200 f/2.8 degrades the quality quite a bit. You would have to stop down about f/8-f/10 before you start getting good results again. If you can go with one of the long primes, that's where I would suggest you go.

I saw the Canon EF 400mm f/2.8L IS USM for the first time "in person" today. There is a local shop pictureline.com which rents lenses. They had it on display. $80/day is the going rate. If only I had had a reason to take it with me ... it'd been rented in an instant! :-)

haha, ya, if i had 5grand, then i might consider getting that piece of glass. then again, i could just settle with a mark II, 400 f/5.6, 16-35 and heaven knows what else.

I have been thinking the same thing...sell my 70-200 f/4 and get the 100-400.

But I am very happy with image quality with the 1.4x plus the 70-200 f/4...are you guys saying that the 100-400 would not be as sharp as the combo I am using?

I have a 70-200 f4 and the 300 f4 available for rent and the 70-200 2.8 IS will be back eventually..
