non reflex cam quistions

[ecozyz]

Just got my a-cam (http://www.ikonoskop.com/] and thats great.

The problem is that its "born" with a very nice 9mm kinoptik optic. ( c mount)

The other day i needed the abillity to make a "head N Shoulder" shot.. ( difficult with a 9mm)

then I was thinking..:

 

are the Sidefinder optics worth enything!? ( compared to modern optics) ( some goes for $1200)

eg. like this one

Was considering going for a PL/ arri st. -> cmount ( the a-cam has a c mount) and then going for a 16mm.. maybe 20mm zeiss as the "beauty shot" optic, and the kinoptik as "see what you get" optic ( the paralel "finder" is fixed for 9mm)

Guess I would find the "limits" of another optic after a few pictures on eg. a wall from 2-5 distances... ( just to check the framing.. etc..( will paint the "frame" on my monitor)

finally

Anybody with experience with the century 3,5mm optic..

saw some shots done with it..

and i sunlight is doesnt entirely cower s16.. ( guess at f-stop 16-22) does it cover s16 at eg f8 ?!
