I'm considering using the "Fotodiox Pro Lens Adapter, Miranda" on my Nikon D3300. Fotodiox advises that it is:

"-Not compatible with Nikon APS system- ".
"Because it has a corrective glass for a full frame camera".

Has anyone tried it on a DX? How about the removable corrective glass? Why is it even needed?

I intend to attach a bellows and/or extension tubes anyway. What can I expect? Use would be slide copying, but it would be fun to use some my Miranda lenses, even if in manual.

Thanks for any comments.

The lens in the adapter is needed to allow you to focus to infinity.

So it compensates for the lens extension (length of the adapter)? I can handle that for slide copy work. I'll need extension anyway. Too bad there isn't some calculations or a chart I could use to set up the copy stand (at least I haven't found any).

Why would the DX work any differently then FX with the adapter (other then crop)?

Thanks!

The miranda registration is 41.5 and nikon 46.5

http://www.graphics.cornell.edu/~westin/misc/mounts-by-register.html

so the point at which the miranda lens focuses is 5mm in front of the sensor with an infinitely thin adapter :) so the lens needs to sit in the mouth of the mount by 5mm where it will hit the mirror. So an optical adapter is needed in order to refocus the lens sort of a small teleconverter.

The converted lens will probably count as af af-d screw.
I think the issue is either metering or focusing. On the 3300 and similar there will likely be no focus confirmation or metering.

You perhaps could get away with an external meter but no focus confirmation will make life very difficult.

The cheaper nikons are not as adaptable as their higher end counterparts

Thanks, that explains a lot. And, I just looked up the adapter on Amazon, and they show it mounted on a D3000 DX camera body!

I was at first dismayed yesterday when I tried to simply hold my Miranda lens in front of a D3300 body. No image! I was in Aperture Priority. On a hunch today I tried again with the body in Manual, and of course it works!

Fotodiox SAYS they are removeable, although I haven't been able to remove them from the two adapters I have, they are screwed in very tight. Should you succeed in removing yours the lens will not focus to infinity, as already mentioned, and you will no longer have the roughly 1.4X magnification from the corrective lens. You may or may not have a slightly sharper image with it removed.

Do you use the adapter on a crop camera? They say no, but there picture is of a D3000 with their adapter!

That should work as well as my Fotodiox adapter for Exakta. With the corrective lens removed it adds 9.6mm extension (yours may be different). No problems with DX or FX.

I think someone at Fotodiox is confused.

There is no difference in the registration distance of Nikon FX and DX cameras. If there was you couldn't use an FX lens on a DX camera! So, if the Fotodiox adapter can be used with a full frame Nikon it can be used equally as well with a crop sensor Nikon.

I noticed some comments about reduced focusing ability due to the need of using the adapter in Manual Mode. This can be overcome by some experimentation using live view instead of the eye level viewfinder. Once you have the focus "locked in" for one slide you can use the same setup for all of your slides.

Good to know! Hopefully I can get the glass out, if I need it out.

Resgister of DX = FX That's what I wanted to hear! I couldn't understand why it would make a difference. I understand about the adapter being a little too tall for a direct fit.

Thanks for the comments.

Probably an easy mistake, what with all the adapters they make...
