Default Canon 70-200 Help

I'm in the market for a good L Series Lens, but I want to know if it is worth getting IS. I can't really budget for the 70-200mm 2.8 IS so I thought about the non-IS. If IS is that important could I step down to the 4 IS?

I know it depends on what I'm shooting, but I want some honest feedback. Can I shoot sharp images within a Church (Low Light) without a tripod with a Non-IS lens?

The only time you need image stabilization is when you need to use relatively long shutter speeds.

The Rule of Thumb is that the shutter speed should be faster than the inverse of the focal length times the crop factor. On a 'Full Frame body, that's 1/70 to 1/200, and on an APS-C body, that's 1/112 to 1/320. (Of course, that's with reasonable precautions.)

So if you can keep the shutter speeds faster than that, you don't need image stabilization. If not, or you're not very steady at the best of times, you should get the stabilized version.
  • The lens is the thing.
  • 'Full Frame' is the new 'Medium Format'.

I would say that you would need tripod in side a church the ones in the uk usually dont have a lot of light.

most churches here in canada do not allow photography or even tripods.
on special days and with permission they may allow handheld.
so a big lens like a 2.8 might be too obvious esp. if your trying a 'quickie'.
ever think about a wide angle instead, way sharper and smaller.
