Is image stabilization all it's cracked up to be and do you really get a couple extra stops out of it? Does it degrade image quality at all?

For example, two similar lenses are about the same cost:
70-200 F/4 IS USM
70-200 F/2.8 USM

With IS, wouldn't you be able to theoretically go lower than 2/8?

The IS does nothing if your subject is moving.

Yes you can, but will you get the same depth of field that the 2.8 gives you? the same bokeh?

It really depends on the subject of your photography. IS is fine if the image you are photographing is not moving. Faster glass allows you to go to faster shutter speed and stop action more effectively.

Remember that IS doesn't help at all if the subject is moving. Nothing beats fast glass...

Faster, faster, faster. Faster WITH IS is great!

Exactly. I take bigger aperture over IS any day of the week. Of course both is better and I find the IS on the 70-200 sometimes very helpful but I would for example never exchange the 24-70 for the 24-105 IS lens.

Fast seems to be the way to go. Thanks.

How do you guys feel about IS for moving subjects?

Unless your in "mode 2" and panning I'd say its pretty useless.

Heh I was tracking an airplane with a 100-400L IS that i was borrowing. Each time you try to center the Aircraft in the shot (you physically moving) the lense compensated for my moving. It was like fighting the lense to center my subject.

Remember you can turn the IS off.

IS is useful if your subject is stationary or very slow and for some reason, you cannot use a fast prime and/or a tripod.

If you want to shoot in low light, I'd much rather have a f1.4 prime lens than IS on an f4 lens.

Don't forget that faster lenses give you other things as well that slower IS lenses won't. Things like a brighter finder image and better AF performance.

The lens was setup wrong then or has old IS.

When I shoot motorcycles (very fast moving) at slow shutterspeeds (and panning) I always use VR/IS. The lens knows I am panning, it is programmed to detect it and it will stop all compensation in my panning direction and only compensate for the movement at an angle to my panning. When I pick up my subject for the AF system I move the lens around a lot to get it where I want but the VR never obstructs the composition or AF.

IS eats camera batteries, faster lenses don't ;-)

I was using it on a 16 year old Canon EOS Elan though has nothing todo with it. The lens has two IS modes, and of course off. Wasnt my lens and i halfway dont know how to use it. But when i went to center the IS countered and for a second the plain was still hwere it was. Counter back it moves again. Very slight movements, very sliht counters it keeps the plane where it is in the view finder. First time using a lens liek that.

Had a similar experience with ragamuffingirls 28-135 IS, i do like that as a cary around though. But I cant buy lenses for my 35mm, cant jusstify the money.

Sounds like with the 100-400 the lens was in the wrong mode.

As for the 28-135, it has 1st generation IS, which does not have a panning mode.

I sold my VR Nikon 18-200mm b/c at the critical time I needed the VR to work (theater etc..) I got movement of the subjects! I now have the 80-200mm f2.8 and it is much better for me.

Seems like most people are in favor of faster glass, so I'll play the devil's advocate.

At 200mm or 400mm even, IS can be the difference between handheld and tripod. Recall that a safe handhold speed is 1/focal length or 1/200 to 1/400 (depending on which lens we are talking about). If you can get 2 stops out of the IS then you can shoot down to 1/50th-1/100th (with 2 stops). The 2.8 may not be able to compensate that much and you may find that handheld you are constrained to using the wide open apertures only. What happens if you want to shoot at f/8 or f/11? The IS helps this happen in handheld, the fast lens does nothing for you. f/8 is the same on a 2.8 as a 4.0.

Just pointing this out. I like fast glass too, but I also like IS. The argument always comes up because the answer is "yes". Both have their uses. The uses are different.

Indeed, Doc, and let's not forget that large apertures have their limitations/drawbacks as well, particularly:

- Most helpful in low light. Outside or in the studio, the difference between 2.8 and 4 probably won't be an issue.
- Larger, heavier, more expensive glass.

With a buying decision coming up, I'm leaning toward the 24-105 over the 24-70, for it's extra reach and IS.

I would prefer to have the both
07/25/2007 01:17:38 PM · #21
I agree with Jason. I have both F/2.8 without IS and F/4 with IS lens. Both have their place. I like the IS because I can shoot down to 1/15 in low light and don't need a tripod. I've been in situations where I was at max aperature with my 70-200 and I had to to start jacking the ISO up to get the shutter speeds that I needed. Depending on what camera you have, ISO 800 can be pretty useless because of noise.
Yes, nothing beats fast glass. But, most of my shooting is outdoors and I don't need it. If you're in to weddings or spend alot of your life in the dark for some odd reason, then yes I'd say you need it. As far as the average individual goes I'd say don't spend the extra money on F2.8 unless you have absolutly determined you need it.

If you're tripod challenged, as I was (in other words too lazy to use one - even though I often carried one), then IS is certainly a blessing for the hand-held photographer. But, IME, I make better photos when they are more considered and that means reliant only on the glass quality and tripod. I switched from the 28-135mm IS to the 24-70mm f/2.8 and use my tripod more often these days, even in NYC (despite the blasted mayor and his petty rules). I think, for me, this path is also leading away from zoom lenses to primes. But that's just my experience.

I'd say the same thing about IS.

And I would agree. I should've included that also.
