Review: Have fun with old glass; no optical loss cheap portrait lens with APS sensor - Recently bought Nikon Z50 APS sized sensor; have some old M42 (Pentax Thread) some over 50 years old This very well built adapter lets us play at being photographers again! Very well built solid metal well machined. Do not loose or discard tiny Allen wrench in package; you may need to assure lens settings show up on top, could have better instructions. No optics, as opposed to Nikon F to M42 adapters so no distortions. Well dimensioned; focuses at infinity as it should Works well with most M42 lenses I have, must be fully manual; fixed not Auto ISO; you only set shutter speed in camera As in old time cameras you manually focus wide open then stop down to adjust exposure. On preset lenses and those with manual/auto switch just use switch to step down Exposure is the most fun, no match the needle, just follow histogram changing speed as needed Best results an old Pentax SuperTakumar 50 mm becomes a portrait lens. Only problem a Sun 24-40 Zoom that has f/ stop ring against back; it binds with adapter and difficult to use Cheap fun; M42 lenses are plentiful and some are excellent
Review: Perfect – works flawlessly and beautifully made - I had purchased a well known name brand adapter ($50+) to couple my SMC Takumar 50mm f/1.4 lens to my Nikon Z8 – wouldn't work properly. To the company's credit they did try via email to help me out but couldn't so it was returned. Took a chance on this "el cheapo" adapter – it fits the Nikon Z camera mount and the M42 thread mount perfectly – and the lens focuses to infinity as it should. More surprisingly, the fit and finish is far superior to the brand name adapter. It has a nice heft to it and looks like it was made by Nikon specifically for the Z8. I was astonished. You can loosen the three adjustment screws with the provided hex wench to align the lens's index mark properly with the camera. This worked well for me but you must be very careful to make sure the wrench is seated properly in the screws' sockets – they are very tiny.

### ⭐⭐⭐⭐⭐ Works just fine
*by L***G on August 16, 2025*

I didn't want to drop a lot of cash on an adaptor for some very old lenses that aren't going to get much use on my camera. Given the choice available I'm happy with this purchase. It certainly feels like a more expensive adaptor. It's a solid piece of metal, nicely machined. I didn't have any issues attaching the lens or the adaptor to the body of my Nikon. So, good value for money.
