I feel it is incredibly relevant for the filmmakers of today because it discusses issues such as the possibility for everyone to be filmmakers with cheaper technology (and the problems with that), as well as dangers of adapting to either Hollywood or the snobbery of the European intelligentsia.

I wrote some more detailed account of my own thoughts on it here: “Art will not disappear into nothingness; it will disappear into everything”.

]]> 25mm lens on 2x crop sensor identical to a 50mm lens on FF? http://personal-view.com/talks/discussion/1449/25mm-lens-on-2x-crop-sensor-identical-to-a-50mm-lens-on-ff Mon, 14 Nov 2011 20:01:44 +0000 jimtreats 1449@/talks/discussions
I just thought i'd ask you guys that are smarter than me on these things.

I wondered as the title suggests if a 25mm lens on a 2x crop sensor, ie. micro 4/3. Was identical to a 50mm lens on a full frame sensor.

I kind of assumed they'd be very similar, with identical FOV, but i don't know quite how or why but i assumed that perspective would appear different for very close and very distant objects due to the 25mm lens vs the 50mm lens. Something that cropping alone doesn't perfectly imitate.

The reason i ask is a friend is trying to setup a 3D camera in a 3D package to be equivelant to my GH2. Forgetting movie shooting crop differences and assuming 2x crop, i'd told him 50mm lens equivelants. He started to question whether perspective looked right and i suggested that he actually used the 25mm lens and using camera aperture to simulate the 2x crop. Apparently doing so causes identical renders to be performed, something that I didn't expect if there were differences optically between the two scenarios.

If there is a difference between the two setups, what causes the difference?

Thanks a lot!!

Cheers]]>
