Illidan said:hi guys. i don realli understand what u guys mean by 1.5 crop factor on a ccd chip. can explain in detail? if its a 1.5 crop factor + a 95% croping on d viewfinder, would d pic be enlarge alot more once its print out than looking through d LCD? thanks alot
Witness said:this is because the ccd sensor is smaller than a film plane...

everything else...properties of the lens...distortion level etc stay constant...
cheers..

The handhold 1/focal length is just a GENERAL rule, use whatever shutter speeds you are comfortable within your intented focal length.
cuxiaowang said:the most interesting thing is, my repeated question remains unanswered...hmm, do i smell more philosophical air than substance?...birds or otherwise. pardon the pun ok!
now seriously think about its, guys...did ANYONE ever did answer my question upfront...when you handhold a 18mm for a less than full frame DSLR, is it technically (not theoretically) superior to work out at 1/actual focal length or just simply 1/cropped factor length would do. if yes, why? if no, why?
at this point, believe anyone uninformed, or even as put, "generally" informed (thats including me course) would just play safe to hold at the larger value (FL). but this is still a geniune query nonetheless..not to dent any egos, is this too much to ask for here or is just a tat tuff to say "I dont know." ....cos i admit i dont
