Re: Interesting shots - but what about the maths?

Shouldn't it be 7x for the crop mode (or 7.2x according to cameralabs tests)
and also another 1.6x for the APS crop factor

(I believe the APS crop factor still applies? Cameralabs figures suggest it does. 300mm lens becomes 3456mm)

yep! i just looked and the manual and your right, it is 7x. wasnt aware of the cameralabs tests of 7x2x. i had it in my head from reading the manual awhile back that is was 6x. thanks for that correction.

does the 1.6x crop still factor in? i dont have a clue. if so what's the final equation?

thanks for the clarification!
