A lot of people are maligning the low light AF capability of the 5D2, particularly relative to the 1Ds3.

I do not fine AF on the 5D2 to be a problem in low light, static objects. In fact, properly used...or at least use the way I do...I find that it will AF in light lower than I can expect resonable IQ (very high ISO) exposures.

I know the 1Ds3 has a lot of AF functionality, particularly with moving objects and off-center points. However, I believe I remember (pls correct if I am wrong) a past discussion of yours where the wider 5D (or xxD) AF point(s) were better at low light than the narrower 1D/1Ds points.

Could you comment on how each of these (5D2, 1Ds3) will do in low light using center point only and/or exterior points.

Thanks...John Schwaller

Good method. I think you would have even more control if masking was used on the layers rather than the eraser tool.

Hi, Chuck...

Can you explain the reason behind the precaution "...Camera-to-subject distance should be no less than 50 times the focal length of the lens..."

Thanks....John Schwaller
