Very useful bag that packs flat and can hold a sony a7rv and a lens or two

Works as described with my Sony camera.

I have a Sony A74 and a bevy of lenses. This camera bag has been a godsend. It is smaller than a full size 40L plus bag, but it has storage galore. It holds 4 lens and my camera body with ease. It's got a magnetic flap cover hiding the zippers for the top pouch which I love and it's got a well designed side opening that allows you to grab your camera fast and effortlessly. The design is pleasing, it's a square backpack, and the colors are nice. I got the black and leather accent bag and It looks really professional. Lastly, there's a tripod tie down and all the zippers are really strong. The stitching on the bag is excellent and the fabric is really strong. I say this is the perfect camera bag to get.

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.

Analogue lenses have character and charm - that's for sure. And they are often many times cheaper than their digital counterparts. So why not adapt the good "old glasses" to a new camera? I already own the Neewer adapter for my Minolta glasses and now I wanted to test this K&F lens adapter for my M42 lenses on my Sony a7III and a6300. Today I also added the Minolta(AF)-NEX adapter to continue using my old Sony A-mount lenses.

I placed particular value on the following two points: quality and function.
1. Quality:
At this price (Minolta AF or Sony A-Mount), you can expect a little more from a lens adapter. To get straight to the point - my expectations were fully met.
Packaging:
The adapter arrived very well packaged and, in contrast to the Neewer adapter, even has a resealable plastic box. In this you can transport or stow it very well when you don't need it. Because we definitely don't want too much dust getting into the adapter and then into the camera.
Adapter:
The K&F adapter is made entirely of metal (brass and aluminum + a few steel screws). It feels very high quality and you have the feeling of holding something solid in your hand. The thread is very clean and well made. My lenses could be screwed in and unscrewed again without jamming. That's the way it has to be!
The fit on my Sony a7III with E-mount connection was very snug and tight. There was no wobbling or sliding after the adapter snapped onto the camera. It was also easy to dismantle thanks to the grooves on the surface of the adapter. This was thought through and not just valued for the optics.
The aperture selection on the Minolta AF adapter works excellently and feels "full" and easy to use. The f-stops therefore sit correctly and are not accidentally adjusted.
2nd function:
The adapter actually only adjusts the back focus of the "old lenses" to the new camera. He does this job excellently! Focusing to infinity works perfectly and the images are not affected by any additional lenses. Of course it depends on the lenses what the end result looks like - in my case I have the Porst wide angle 35mm f/3.5, the Auto Exaktar 135mm f/2.8 and for the Minolta AF the Samyang 16mm T2.2 used (see sample images).
I'm really happy with the K&F adapter and I'm sure I'll still have a lot of fun with it and my old lenses. I would buy it again anytime.

Edit 03/04/2019: I've even bought the Minolta(AF)-NEX adapter because I've only had good experiences with the products from K&F so far and I wasn't disappointed this time either. Great product and thanks to the choice of aperture I can now continue to use my old Sony A-mount lenses.

I bought and paid for the K&F adapter as usual via Amazon, but I get the money refunded as a product tester. As always, my opinion remains independent and honest.
