Okay here it comes.
for example an aps-c sensor like the sony a58 has with an 8mm f 3.5 fisheye will cause heavy vignetting right?
in case full format is auto?!?!?!?! if i put aps-c size capture on it shouldnt show any vignetting, right?

man those dslr's/slt's are confusing :rofl:

ty in advance guys

If the 8mm f3.5 fisheye is designed for APS-C or for Full Frame, then it will not heavily vignette on an APS-C sensor camera.

If the 8mm f3.5 fisheye is designed for ONLY APS-C, it will function fine on APS-C, but it will heavily vignette on full frame.

Basically, if a lens is designed for a larger format, it will function fine on smaller formats. If a lens is designed for smaller formats, it will not function properly on larger formats. APS-C is a smaller format, so any lens that works on full frame will work great on APS-C... but anything made for APS-C only will likely not work as intended on full frame.

I've reiterated a few times to hopefully be clear. If a full frame camera is put into APS-C shooting mode, it will have reduced megapixels (ie. a 24 megapixel camera might only get 6 mega pixels, or somewhere around that in APS-C mode).

Also need to keep in mind that some Crop sensor lenses are Only for Crop sensors. Ie; EF-S lenses.

Yeah thanks i just thought anyhow that the a58 from Sony was a fullframe cause of a Video :wacko: didnt realize that the guy used an a99 ^^
