Rob - the 100-400 will be useless indoors without relying on external flash (and focus assist beam). But f2.8 isn't much good if you need more DOF for boats - in which case flash is the answer. What exactly are you shooting indoors that you want 400mm for?

Outdoors,no question the 100-400 will outperform the 70-200 with 2x. It will be sharper and focus much faster. Plus it has IS which can be a bonus on a 400mm lens.

Thanks for the reply.I would mainly use the 100-400 outside,probably really dont need 400 inside,I was thinking of if I zoomed in on people like inside a car show or other events,I dont believe a flash will reach out far enough and spoil a candid shot.

How will the 100-400 work in a low light or over cast day outside?

Thanks
Rob

Some of your shots look like the they can use some +EV of 1/3 or 2/3 as the iso is pretty low and you have good shutter speed with the dark shot with the second post, number 2,3 and 4. As it looks to me like the camera was fool by the lighting conditions and the white background.

And a bit of wb issues also on the indoor shot form the show, but it show most of them at f2.7. F2-f2.8 seems to be a good aperture for shooting shows without a flash. As a flash will cause a lot of flash wash and reflections when shooting a glossy object like polish boat hulls.

If you are saying it is $700 difference, I think you are referring to 70-200mm f/2.8 L IS II USM Lens - is that correct? If yes, it is a magnificent lens ... if budget permited, I would buy 70-200 f/2.8L IS II even though I'd loose the additional 200mm in the bargain.

Small question ... if I shoot at f/4.5 or higher (with 70-200 f/2.8 lens) wouldn't I be able to get the required DOF or match the DOF of 100-400L?
