70-200 f4 IS vs. 70-200 f2.8 Non-IS

[...]Again I hawk, but this video was shot completely hand held, with a little support from a bungee cord, from a helicopter traveling at almost 100 mph:

Really nice shots, there. At first read, I imagined you hanging at the end of a bungee cord. Shame about the dust; that sort of thing drives me nuts. Was it between the lens and the UV filter? It appeared to be moving and at first I thought it was the helicopter's shadow—until the shot of the large shadow appeared.

But yeah, definitely an IS endorsement.
 
not to start a huge poop storm, BUT, if you were so inclined to wait till canon releases the new IS system on these lenes (Vince Laforet demo'd it on the DSLR workshop he did, and man its amazing, you can shake it around like crazy and stays still)

you could always just get a vivitar 1 series 70-210 3.5 like this

Mine only cost me $65

Done plenty of tripod , and slider mounted shots that are all buttery smooth and im sure many of you have better fluid heads than mine. (fm18)

Ive always heard if your on a tripod you should turn the IS off, because it can try to correct for movement, and mess up a shot? (for video). Is this wrong?

Yeah... I think I'm just going to bite the bullet and spend a small fortune and get the 70-200 F2.8 IS 2.

I figure since I'm using it with the 2x Teleconverter, shooting at an f5.6 is doable but f8 may be pushing the line a bit.

I suggest reading up on the 2x extender. You'll lose 2 stops, AF speed, AF above f/5.6, sharpness, and IQ.

Why not simply buy the 100-400 f/4-5.6 IS? Perhaps that way you can smile now and later.
 
I just tested a Tokina 80-200 2.8 without IS on a 7D and 5D, and am posting a review shortly. You don't need the extra speed at all if you're shooting out doors; I never used 2.8 during the day on that lens; it made the shutter speed too high. For night shots, outdoors, it was handy.

Get the one with the IS, it's very useful. Without IS, there is too much jitter, you could only use the lens on the tripod. Even on the tripod, if it's gusty you can get jitter and jello especially out there at 200.

I know this is probably correct, but in the sample video of the horses that I posted earlier I used the 2x extender several times and I doubt anyone can see any perceptible quality difference.

I'm not suggesting using the extender with this lens all the time, but for me I could get some great close ups from 50 yards away without having to move my fatness closer. Its quick and easy to install and adds considerable flexibility when you need it.

I don't know about the AF speed, shooting video I never use AF. But this lens and extender are a dream to use. Now that I've used one I'm dreaming about getting one...

Want to see another video?? :banned:

Didn't make it through that one—the song annoyed me too much.
 
Just one additional comment...

For those reading the "f4 is sharper" comments, I am NOT disagreeing with that statement, so don't jump on me for this, but I sure wouldn't walk away reading those comments thinking the f2.8 isn't sharp (talking v1 IS here). That lens is still mind blowingly awesome. So take the sharp comments with a grain a salt, it's a relative thing, and for video, I doubt it would come into play at all (I wouldn't trade it for the f4 if you paid me).
