I got the filter for the 55mm Sony/Zeiss lens. The front lens is set back here... but you never know. In any case, the glass is high quality and well coated to allow for high transmission and few reflections. Even in poor lighting, I don't see any flares that wouldn't be there without the filter. I can definitely recommend it.

am the owner of a mirrorless Sony A7rii and for me the best thing is to revive old glories like the Zeiss 50mm f1.4 which, despite its age, always produces great photos, even on a digital level. This adapter from the K&F Concept Pro series is then really well finished, all metal, adapts perfectly to the camera body and lens, the interior is then matt black, essential for light spots and the result of a damaged photo.

This ring allows the prestigious Zeiss manual focus lenses with Contax/Yashica mount to be fitted to a Sony Alpha (E-mont) camera body. The connection on my Sony A7III and A7R4 is perfect with no play. The same applies to attachment with C/Y bayonet lenses. The ring is made entirely of metal, heavy but superbly finished. No reflection in the ring. I am really very satisfied and for this reason I rate the article with 5 stars.

It's easy to use...fits my Zeiss 16-35mm and my 24-70mm and gives me very nice results...allowing me to dial in the right amount of exposure for the effect I want!

In a nutshell, because a lot has already been described above. I compared the approximately 5 times as expensive (and heavy) Zeiss 85 f 1.4 on my SLT 99 with this mini lens on the Nex 6. Test scene: Roof front of the neighboring houses about 100m away, camera tilted by 45 degrees, so that the front goes from corner to corner. Workflow: Tripod, shutter release delay 2 seconds, stabilization switched off, aperture priority, ISO Auto, shots in RAW (internal corrections switched off), in Lightroom, default setting "developed", lossless downscaling of the 24MP image from the SLT 99 to 16MP in a TIFF file around the Comparison on the screen at 100% view for the 85 not to make it unfair. Shooting at f/1.4; 1.7; 2.4; 5.6;8 and 13 for the 85, 1.8; 2.5;5.6 ; 8 and 13 on the 50's Nex. Result in terms of sharpness: I didn't want to believe it, I repeated the test twice: There is a better lens than my 85, which was previously classified as superlative. Up to an aperture of 5.6, the 50 is clearly sharper in all comparable apertures, both in the center and in the corners. The 85 lags behind by about 1 to 2 f-stops and only achieves with an aperture of 5.6 what the 50 can already do with an aperture of 2.5. At aperture 8 and above, both lenses pull the same. So if you don't necessarily need the considerably larger exposure potential of the full format and the aperture 1.4, the 50 Nex is the best choice. PS: without downward scaling, the purely visual result is even more desolate for the 85.

I am impressed with the quality of the Starscope Monocular by VivReal. Zoomed images are very clear and it is easy to focus. It is nicely packaged with accessories; smartphone holder, remote control, carry bag, tripod and cloth. I have a couple of tripods I will be using with it since the accompanying tripod is small and limited in its use. The smartphone holder takes time to get comfortable with. I haven't had a chance yet to get really good focused pictures with my iPhone. I am hoping with time I will get better at it. I primarily use the monocular for looking at birds and other wildlife. I look forward to many hiking adventures and trips to the mountains using my new monocular.

Great filter . Using this on my Zeiss 16-35 f/4 on a Sony a6500 for film use. The picture and build quality of the filter is good value for money , made with quality glass . My only complaint and this is pretty big deal for me is my lens hood will not fit while using this filter . It’s one or the other for me now , which is a bummer.
