I like to know if there is a adapter that will let me use Nikon lenses on my Sony A77? Thanks Redeye :roll: :roll:

Fotodiox has one on Amazon for $39.95 and shipping. It will be a manual focus lens as the electronics won't work on the lens.

Novoflex makes high quality adapters and one specifically for Nikon lenses on Sony E mount (NEX). But, they're currently on back order because of the high demand. BTW, if you're going to put good Nikon lenses on the Sony a7, why put a cheap adapter between them? It will likely affect the overall quality of the final image.

Oops, sorry...I went back and saw you were asking about the Sony A77; not the a7. I don't know about adapters for the A77.

Check B&H. Last time I looked it seemed that there was an adaptor to make anything work on anything.

I take it we're talking Nikon F mount.

The problem is that the registration distance is longer than that of Sony/Minolta A-mount and that means that to get infinity focus, you need a lens in the adapter and that inevitably degrades the image; how much will depend on the adapter but a cheap adapter will be just that.

An alternative is Leitax but this replaces the F-mount with an A-mount bayonet and may be unacceptable if you use both camera brands.

The adapter internal lenses are only needed if using a lens other than Nikon on a Nikon body as it has the largest setback from lens flange to sensor. In the case of my old macro Canon lens to my Nikon, the Fotodiox adapter works well for macro work without the adapter lens. It just doesn't focus to infinity, not an issue. With the internal lens my adapter is not sharp and crisp so I don't use it this way. Maybe another sample would be better. The adapter itself mounts to the camera and lens snugly. If it were a Nikkor lens mounted on a Canon body the adapter wouldn't have an internal lens and so wouldn't be an issue.

All lenses are designed to be placed at a certain distance from the sensor. Too far away and you won’t get infinity focus. In fact – if it’s off by just a few millimetres your lovely lens will become a macro optic only useful for taking snaps of insects and flowers.

So what DSLRs will your current lenses adapt to? The rule to follow is to see what your body’s flange size is. That isn’t innuendo it refers to something technical! Let me explain…

The flange size is the distance between the mount and the sensor. Essentially if your DSLR body’s flange is longer than that for which the lens is designed for the lens can’t be used. If it is shorter and you can fit an adapter in the gap then the lens will be at the right flange distance to focus so all’s good to go.

Actually what really matters is the distance between the rear lens element and the sensor, but the mount and the mirror have the biggest influence. The mirror can get in the way of the rear element and the mount’s flange distance can stop the rear element from being close enough to the sensor for infinity focus.

For example – Canon made sure to make the EF mount incompatible with the previous FD mount. EF is larger at 44mm whilst the old mount was 42mm. So lovely FD lenses cannot be used on Canon bodies without being rebuilt, or without degrading corrective optics in the adapter.

With the upcoming Sony A77 looking very promising for video, I am wondering which of my lenses will work and which won’t so have done some research. The A mount is based on the old Minolta SLR mount and is 44.5mm – even longer than the EF mount!

Nikon and Contax Zeiss

Nikon lenses have a 46.50mm flange – just 0.5mm shorter than Leica but that is enough to knock off infinity focus on a Sony DSLR, ditto for Contax Yashica (CY) Zeiss lenses, they are just 1mm over the Sony mount at 45.50mm. Adapters do exist on eBay but they have cheap and nasty corrective optics and won’t produce a sharp image unless you stop down significantly.

UPDATE: Dan Chung tells me there is a hardware mode that lets you use Nikon and Contax lenses on a Sony Alpha. Check this out here and here.

I take it you have some old Nikon glass, and the price of Sony glass is prohibitive. Whether I guessed right or not, did you know that Minolta Maxxum lenses (or the aftermarket equivalent from Sigma, et al,) will work just fine on your a77, and for a fraction of the cost of Sony lenses?

Thanks for all feedback.
