IMO, it depends on the lens and what you're shooting. I don't think it would make much of a difference for taking photos of people or other moving subjects (incl. trees on a breezy day) at the focal length you're using right now. By indoors or low light I'm going to assume that the available lighting is necessitating longer exposure times (for your set aperture and ISO) which is resulting in blur.

At 55mm on a crop sensor, you're at ~85mm. With good technique for a handheld shot, you're "wanting" at least 1/125th of a second (1/60th being too slow and going with full-stop adjustments). At 18mm you're "wanting" 1/30th of a second exposure.

Throw IS in there and sure, you might take photos up to 2-3 stops slower (1/15th sec at 55mm and 1/2 sec at 18mm), but unless your subject matter is very still you're going to get motion blur anyway.

Open up your aperture and/or jack up your ISO to compensate for the low-light. "Noisy" photos aren't as desirable but I'd rather have sharp and noisy than blurry and noise-free.

Oh, and on the other hand, IS can be nice (thought it does introduce a shutter lag).

I've shot photos of a friend of mine finishing Roadside Attraction in the shade from the anchors of C Sharp with the 70-200mm and a 1.4x extender, handheld, on a crop-sensor body. The IS made a huge difference there.

Shutter lag? Really? On a DSLR with an IS lens, the IS causes shutter lag? I never noticed. How much, and how?

And how do you do the quote thingy? I've never tried that before.

IS can be cool, but it does depend on your subject - it can't stop subject motion, just camera shake. I use it on longer lenses, but don't know how helpful it is for shorter lenses in general.

So, looks like Sunday the 22nd is the day, meet at Miguels at 3:00, and we can head somewhere else nearby to chat and shoot. Feel free to bring along a friend, etc.

Thanks much for the offer! I think we are going to just meet at Miguels for this class. Will be there around 3:00, so hope some of you all can make it!
