I've done a quick comparison of how various 35mm cine lenses render out-of-focus blur, quite fascinating if you're a lens geek like me.
I tried to include lenses from roughly each decade since the 1930s, by Ross of London, Meyer Gorlitz, Schneider Kreuznach, Bausch & Lomb (Super Baltars), Taylor Hobson (Cooke Speed Panchros), Cooke (S4s) and Zeiss (Super Speeds and Ultra Primes), with focal lengths as close to 32 or 35 as possible. I'd like to add some more frame grabs when I get time, and at least attempt to explain some of the variations. So it's a work in progress.
Any suggestions or feedback welcome!
