JJC GSP-Z7 0.01" Ultra-Thin Optical Glass LCD Screen Protector for Z5 Z6 Z7 Z6II Z7II, Blocks UV, 2D, 9H Water Oil & Fingerprint Resistant, Compatible with Nikon Z6 II Z7 II Z6 Z7 Z5 Camera

I have two of these Leica M to Nikon Z adapters. The first one felt like it was built well and the lens clicked in firmly.The 2nd one, the lens feels loose and I'm noticing now that there is some rotational play in the mount both at the lens side as well as the body. This is NOT the case when using Nikon's own S lenses on the z mount as they are super firm.This is an issue because you will feel the lens move if you're turning a stiff focus ring.Another offender is the light leak. The example picture is 6 second exposure with the lens cap on at f16 (to rule out lens cap leak) so you wont see it this bad normal shooting. However, on a sunny day it will be creeping into your shots affecting it a little.The solution for the light leak is a rubber o ring 42mm inner diameter, 52mm outer diameter with 5cm width. It removes all light leak.The lens moving around in the adapter.. no fix there as the tolerances are just not as tight as they need to be.

Doesn't have any electronic capabilities, but it's a lot cheaper than the FTZ adapter. So, if you want to wait to get an FTZ adapter, this is a nice alternative.

I bought this thinking the Nikon FTZ adapter was too expensive. But this simply didn't work. All I got with it was an almost black image. I could not figure out how to get it to work on my Nikon Z50. I gave up and purchased the Nikon FTZ adapter instead, which works exactly as it should. This was a complete waste of money.

This was the perfect adapter for my needs. Since I shoot manual focus lenses, this is all I needed. The FTZ would be nice, but I have no AF Nikon lenses that aren’t D’s so this adapter is perfect. Fits nicely. Feels solid.

I suppose this adapter tube works fine for the Panasonic FZ18 camera for which it was designed, but the reason I purchased this is because the second half of this two-part adapter (the longer part) fits perfectly on the Pentax FA 31mm F1.8 Limited lens and prevents lens flare better than the built-in hood on that lens.If you own the FA 31mm lens then I highly, HIGHLY recommend purchasing this adapter tube so you can add a quality hood to your lens to block flare-inducing light and protect the expensive front element.

tl;dr this thing is heavy (165g, 5.82oz), sturdy when not using the helicoid, wobbly when using the helicoid, relatively crudely made, but still a lot of fun, and its appearance compliments vintage lenses and the Z7.The other day I came across an old friend, my "first good lens" a mid 1960s Pentax 50mm f1.4 Super Takumar that has been with me for about 40 years. There are a lot of 50mm f1.4 lenses out there, but the Super Tak has a certain something (20g of radioactive thorium, lol) that allow an optical design way ahead of the Zeiss Planar "clones" being pumped out by mid 60s Nikon, Canon, Olympaloopas, etc. A combination of critical sharpness and excellent bokeh.So, I wanted to break it out and have some fun. I took a quick look at M42 to Nikon Z adapters and found a ton: Kipon, Novoflex, FotodioX, Fotasy, Vello, etc. that basically looked interchangeable. They ranged from around $15 to over $200 (not mentioning who that was. Nope. You can't make me say Novoflex. Not gonna do it). They all had a similar awkwardness, like they had the needed large flange at the Z body, but tried to get down to a skinny tube ASAP, so a lens looks like the end of a Q-tip.But then I saw this thing. And I thought of how much time that Super Tak had spent on extension tubes and said "why not". Around 36 hours later it was sitting on my workbench. Not doing an unboxing video.First impression, the thing is a brute. It's heavy, 165g (5.82oz). Put 230g worth of Super Tak and you've got 395g (13.93oz). Looked the mount over, and it looked well enough made to entrust my Z7 to it. It felt right mounting up. Screwed on the Super Tak. The focusing line was about 5 degrees off center. Remembered my M42 etiquette, unscrewed the lens, cleaned the lens's back flange and the adapter's front flange, remounted it, and it was fairly well centered. Looking good, and I mean that literally. The adapter's helicoid ring has an interrupted ridge texture that nicely complimented the Pentax lens, the extra girth means you taper down toward the lens so you don't get the Q-tip effect, it feels nice against the palm of your hand, and from most angles you see the shiny chrome ring of the Z mount and the shiny chrome ring of the lens.Powered it up, played around a bit, then took it outside and checked infinity focus (about as good as any adapted lens). I need something wider to really check if infinity is off. Took some shots. Then I decided to give the helicoid a try. That was disappointing. You don't expect the smooth manual focusing of a vintage Nikon, Leica, or Zeiss lens. But this thing is rough. Fearing for the safety (or at least cleanliness) of my camera, I headed back in the house, dismounted everything, racked the helicoid all the way in and out a few times. Tapped the adapter over white paper, but didn't see any crud through a magnifier, so it's not throwing shredded metal around. It just doesn't feel smooth. And, with the helicoid extended even a little, it wobbles a bit. Fully retracted it feels as solid as you could want.So I gave it a try indoors. After all, it's an f1.4 lens, and I've got awesome stabilization, right? Wrong. Everything looked shakey. I thought "is that wobble a problem even with the helicoid fully retracted. It felt OK. Then it dawned on me, I had not set up a manual lens configuration for a 50mm f1.4. And looking at what I had last done, manual was set for 180mm. (I had a 100mm macro racked out to high magnification). At that setting, instead of reducing vibration, the camera was amplifying it by about 3x. Set it right, and things looked prety good. I won't say a Super Tak is sharp enough in the corners to impress at 46mp, but it looked pretty uniformly off in all four corners, so it wasn't screaming that the mount was out of alignment.Using the full helicoid plus focusing the Super Tak as closely as possible, I got to about 0.9x magnification, which puts the helicoid at about 32mm of extension. Not bad. Am I going to trust it for critical macro work? Not a chance, but then again I'm not going to trust a 40-year-old Super Tak with critical work, either. This is just for fun, and it totally delivers.p.s. I got another Fotasy adapter in this shipment: Leica M to Nikon Z. It is definitely higher build quality than this M42 helicoid, so the quality problems appear local to this adapter.

This adapter is well made and a great value for the money. Ideal for older manual Nikkor lenses and a small fraction of the cost of the FTZ. Well-pleased with this purchase.

Amazing deal! Works perfectly, much less expensive than Nikon’s alternative.

Look good

After I lost my lens cap I purchased this 67 mm pinch cap and they came fast, and fit perfectly. With a string that I’m able to attach to my camera this will keep those roving caps in plain view😁

QUEDARON SÚPER BIEN EN MI CÁMARA, UN POCO MÁS JUSTAS PERO MUY BIEN, LA CALIDAD ES BUENA Y LLEGARON SÚPER RÁPIDO

La entrega fue muy rápida, la calidad del material es igual al de los originales

They do work well and are a lot cheaper than the brand name ones.
