Default Aperture Comparison between Fixed lens & DSLR

Note sure wether this is the right forum - anyway here goes

Hi Gang,

Just found the answer to something I was searching for a long time , it’s a very interesting and useful information so being the nice guy I am, I thought I’ll share it with you guys just incase someone else ever requests the same.

I was looking for the comparison aperture value between a SLR & Fixed lens camera like my Sony DSC H2.

(Note : The values are approximate & may change based on camera specification.)

Wulf - as clarified by the discussion below, this chart explains why point and shoot cameras can't easily play with the blurred background effects enjoyed by DSLR owners. f/2.8 is f/2.8 - a big hole letting in lots of light -but other factors also come into play

Fixed Lens / DSLR (sorry the table formating is not holding)

f/2.8 = f/11

f/4 = f/16

f/5.6 = f/22

f/8 = f/32

f/11 = f/64 (yes a whooping f/64 which no DSLR can beat :-) ) That reflects into awesome DOF ability


Note : Everything which has a Up has a Down and that in this case sadly is the largest aperture which is only as big as f/11 :-( , That translates into a serious handicap for low DOF photography (read less blurring of background at large aperture )


Cheers and feel free to add, comment & provide feedback on the topic.
