IGNORE everything Crocodile Gena said ....

She? made it much too "complicated" .... and is inherently WRONG anyway.

IGNORE EVERYTHING she? said, (including where she suggest that higher ISO setting results in "lower" noise) ...

Most of the other people got it right ....

f/stop remains the same, thus exposure (ISO, shutter speed & f/stop setting) remains the same.

Only the effective focal-length changes, (as in cropping) ...

and effective DOF increases. (albeit, as you saw, you can get into a complicated discussion of DOF).

Thanks for reading .... JoePhoto
