Hi, hi, 
good afternoon, 
 
sorry for that, but I'm looking since few days, and I can't find the exact answer. I'm building a camera set, seeking lenses, patches, follow focus... I'm already working with 550D, but I want to break 16/9 ratio, so I look by the gh2 and hack for artistic solutions. 
  
I'm not this time interested by anamorphic ratio. 4:3 ratio have better ratio framing for picture type I research. I want to know if that is possible to film in 4/3 ratio with and without crop... 
  
Lens I'm finding are prime lomo lenses, in oct 18, for 35mm cinema camera, I'm also looking for a angenieux zoom, for super 16 mm.  
 
what do you think about. can I film in 4:3? does the lens I'm looking for can match? wich patch would be the more interesting for me... 
 
Information are such multidirectional that I can't fixe surly my questions.... 
users advise will, i'm sure, help me a lot... 
best
