hello people! i have seen a lot of bolex h16 rx with angenieux primo lenses (10mm retrofocus, 25 ,50 ...)

this lens is not marked "FOR RX" do you now if this lens is really collimated under f/4??

It would cost you shipping to and from, but a reputable camera place would see if the lenses are RX collimated for free (but you better drop them a line first).

Hello Daniele,

Your best bet would be to take your three Angenieux primes and camera to a shop with an auto collimator and have them checked. These lenses are super easy to adjust, they have three set screws you loosen and reset the lens to infinity with what ever "C" mount camera your using. Any cine optical tech should be able to adjust each one in under five minutes each. I would have them adjusted with running film as it will show you if you have any breathing problem in the gate and will give you the best collimation possible. Also this will confirm that the ground glass is "seeing" the same as the film plane.

In other words - any of the marking on the lens may or may not be correct after folks have played with them for 40 years. A camera tech can adjust them fairly quickly, which means that the bill sould not be too big, unless they also can re-lubricate them, or they find that they need other work.
