Is there an adapter to adapt Nikon FX mount lenses to Sony A mount full frame?

So my plan is to purchase the Laowa 25mm Macro lens to adapt to my MFT Camera, but it'd be nice if my partner could also adapt it to her Sony A Mount camera when I am not using it.

The long registration distance of A-mount cameras (44.5mm) compared to the much shorter distances of mirrorless cameras makes adaptation of any mirrorless lens very impractical. You would only be able to focus on nearby objects unless the adapter contains optical elements that degrade image quality and increase the focal length.

That might not be an issue for macro shooters, but it means the market for such an adapter is probably not large enough for a manufacturer to produce one.

Yes I know, but Canon EF, Pentax and Nikon FX should all also be DSLR mount cameras I think. I don't think I'd be able to adapt the mirrorless mount lenses to MFT either anyway.

I thought the Laowa was designed for mirrorless cameras, but I guess it's not - so I don't know why A-mount isn't natively supported.

I see the lens is available in Nikon F mount, so here's a Nikon F to A-mount adapter (for manual lenses only, of course):

Ah, thanks! So these do work, I wasn't sure if Nikon FX and Nikon F were the same.

Nikon F is a lens mount. FX is just Nikon's designation for the full frame sensor format.

I've used the F mount Nikon 500mm lens belonging to a friend on my Sony A mount gear without issue using a glassless adapter .

Manual focus only , no aperture control and without the glass corrector , the furthest it focussed is reduced .

Using it to get shots of Kingfishers relatively nearby , this isn't a problem .

If your using the lens for macro , infinity isn't needed anyway .

If the lens has manual controls for aperture and focus , then you should be good to go .

I wouldn't bother getting an adapter with the lens in as you take a knock on image quality at the expense of infinity focus .

But it's a macro anyway .

Thanks for sharing your experience! The lens only focusses from 2.5x-5x, would that mean there is no downsides to using a glassless adapter since it doesn't focus to infinity anway?

Because the adapter works as an extension tube , you might run into a problem with that lens .

As with any lens with an extension tube , your working distance is reduced .

At 5x the point of focus could already be inside the lens , rather than in front of it .

Meaning even if 1mm away from the lens , the subject will still be out of focus .

Do you know what the working distance from the front of the lens is at each magnification ?

Lower magnifications might work fine , as long as lighting isn't a problem.

It might mean you'd need to get an adapter with glass in .

With regular 1:1 macro lenses , the 5mm or so extension tube isn't an issue , it just gives a little less working distance at the maximum magnification.

Just seen this on their website ;

"This lens is optimized for macro shooting between 2.5X – 5X life-size. The lens is specially designed with an extended working distance (45mm at 2.5x & 40mm at 5x) and small lens barrel."

So with that working distance you might be o.k with a glassless adapter .

I'd certainly try a glassless one first , before getting one with the corrector in .

There cheep enough in eBay .
