p.1 #1 · optical stabilization vs. large aperture


For poorly lit handheld indoor shots which is better - having only a larger aperture or having only optical stabilization. I am considering the Sigma 70-200 F/2.8 vs. the Sigma 80-400 OS F/4-5.6. Price and zoom range are not considerations.

IS should give you more than the one stop differences in aperture so from a camera shake point of view the IS is better.

But

focussing would be better with the 2.8 and a higher shitter speed stops action bettrer

horses for courses!

However if price is not a consideration - go for the Canon 70-200 IS - or even the 70-200 f/4.0 IS

well...I don't know about that, but wider aperture gives a faster SHUTTER speed, which stops action.

Personally, I prefer aperture over IS, but YMMV. Best is getting both (f2.8 + IS).

Damn - I thought you were querying better focussing with a larger aperture lens and wrote a 4 page thesis in reply - then noticed my original typo

If only everything were so simple. Sigh. One funky option seems to be using the f2.8 and external gyro. But I can't find any compact widely used gyro. Alternatively a pentax/olympus camera with in-body stabilization and the sigma 70-200 f/2.8 should probably help.

External stabilization can get pretty expensive..

Still want to go that route?

IMHO in this case it ought to be that simple. For stopping action in low light, f2.8 > f5.6+IS. Remember, photographers did just fine for years before Canon & Nikon introduced stabilization technology (ok, Sony started it with their camcorders).
