Letus Flip Lens Question

I read somewhere on here that you can't stop down a canon fd lens when mounted on the Letus Flip adapter, which is one of the only two lens mounts for the adapter. The other mounting option is Nikon AI. My question is: can you stop it down when mounted on the adapter? I know you can with Nikon F's, but that is not an option, so far as I know and it is important to me to be able to stop down the lens.
 
I don't know, right now, but my Letus Flip was delivered today so as soon as I get home and get a chance to really play with it tonight I can let you know...

I have some Nikon and Canon lenses, so I will experiment with both and let you know what's up...

Hmm not sure entirely what you have read, I cant change the f stop on my fd lenses at all when mounted to the flip. They are always fully open, which is the way I want them to be.

When you stop down a lens, you are going to a larger number/smaller aperture and therefore less light.

You can do this in the dvx itself so I dont understand where there would be an issue?

this is not fixable. and yes somewhat of an issue, this is why ( me thinks ) one sees grain after a certain fstop on the camera. Some have said it to be passed 5 or 6, grain becomes visible. Now if you could change the fstop on the actual lens itself, would the result be the same or different?
 
you can use the f stop on fd lenses you just have to tap down the little lever that engages the exposure ring.

I will be filming miniatures, so will have to flood it with lots of light. adjusting the f stop will create LESS depth of field, yet still allowing me to use a superwide angle lens, so I need to adjust the f stop on the lens for dof reasons.

Grain on the dvx I have found to be proportional to the amount of light used not the fstop. i.e. at f8 with low light you may see some, f8 with blasting light I seriously doubt you would see any.

You can also keep a more open fstop and alter the shutter speed to reduce the exposure to each field. That would limit you style wise, but depends on how you want the output to look.
