Thx Grimor and Rudolf ! Very very useful informations that finally summarize all what I heard : I have to stop down to be sharp (at least F4) and to keep my 12-35 at (approx) 18mm ! The only thing that I wonder now is : how can I record in low light if I am at F4 or F5.6....it's gonna be hard

Thx a lot Tito ! I'll have a look on it !

Hey guys, I just bought an OPTEX anamo lens + Tamron Diopter (28-200 A9F 72mm) to put on my GH4 and it looks nice, except that I think another diopter could be better (as it's very hard to focus close, even at 2m)... I use it on my Pana 12-35 F2,8 (I know it's better on prime lenses) so could you tell me : 1) which diopters would be better for it ? 2) which kind of lens (prime I assume) will be a killer with it ? 3) what % do I have to put in FCPX to fit : 77% tall ? 4) Is it a mandatory to be at F4 minimum to be sharp ? I saw Andrew's review but I couldn't find what I need. Thx a lot for your help
