It worked great on my Sony lens.

Great polarizer filter for my Sony lens. Fast delivery.
Very satisfied

This filter fits perfectly on the Sony SEL-35F18 standard lens (fixed focal length, 35mm, F1.8). After buying the lens, I screwed on this filter to protect the lens from dust, scratches and other external influences. Recommendation.

I have had the same experience with the M42-Nex adapter.

use the SEL50f1.8 on my NEX-5N. The workmanship is very good and the materials appear to be of high quality. My motivation for buying this lens was primarily the high light intensity and, according to all tests, the very good imaging performance. I was not disappointed in either respect. Even with an open aperture, the edge sharpness is much better than with the (stopped down) 18-55mm kit zoom. From approx. aperture 2.8, the 50mm lens then produces excellent images over the entire range! As with the kit zoom, the built-in optical stabilizer enables relatively long exposure times, even without a tripod. 1/10s to 1/20s are handheld with no problem, or even less if you have a steady hand. Up to now it has practically never been necessary to set the ISO higher than 3200, which makes the NEX a very good "available light" camera. The exposure potential is also very good at an aperture of 1.8 and the bokeh is very pleasant. The focus motor works relatively quickly and quietly, but the aperture blades may be audible when focusing because the aperture is opened. In my opinion, the autofocus is a tiny bit slower than with the kit zoom, but it is fast enough for my needs and, above all, very precise. Manual focus (steer by wire) is also possible and works very well due to the smoothly running focus ring. For videos, however, I find the "crank travel" when focusing manually to be a bit too long. Very precise adjustment is possible for this. If you are looking for a sharp, fast fixed focal length with autofocus, you will have a lot of fun with the SEL50f1.8. In my opinion, value for money is very good.

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.

don't normally give 5 stars in these reviews but this lens almost made my old Nex 3 feel like a new camera. For taking pictures of people, it's head and shoulders above any other NEX lens I've tried (this is my fourth lens). Essentially, the f1.8 aperture lets in so much light that the camera (along with image stabilization) can use faster shutter speeds to get a specific shot, which means a lot less blur and, in practice, beautifully sharp images. The f1.8 aperture also defocuses the background of the shots, making for simpler compositions that emphasize the main subjects in the frame. Also unlike many fast Primes, this pen is sharp down to F1.8. Of course, the 75mm equivalent focal length makes this a single-purpose lens, but don't let that put you off - it's a purpose that most people will need plenty of, and there's nothing wrong with doing one thing well. Here is a real example: Last year I went to a wedding. A nice occasion but the ceremony was indoors and it was a dull gray day. I used the stock zoom lens that came with the Nex (the 18-55mm) and none of my images came out all day; they were all blurry because people were moving too fast and I couldn't react in time to catch fleeting moments and that was because the zoom lens can only do about f5 at its 55mm zoom end and in any case it is on this one Focal length not very sharp. Last weekend we celebrated my little son's christening. A nice occasion but the ceremony was indoors and it was a dull gray day. I used this lens and every single one of my photos came out perfect - beautiful. No need for flash, no need for high ISO. I was even happy to set the camera to the default settings and let my friends take photos for me because I trusted the lens to get a good picture. I've never done that before! One thing I've found is that I have to go a step further backwards than I'm used to because the lens can't focus close-up. You must be a few feet away from your subject. In every other respect, this is the best money I've invested in photography since buying the camera. I was nervous about buying this as it's more expensive than the entry-level lenses in the Nex range. It turns out there's a very good reason for the difference - it just has a much better "success rate" for getting the right photo first time than any other lens I've used; it complements the money I originally invested in the Nex camera and adds another dimension it didn't have before.
