The camera on this headset works surprisingly well. Since it is a Sony HD wide angle camera, you can be sure of its quality. Setting up the headphones and microphone was a breeze and music playback was excellent. Easy to connect to other Bluetooth intercoms and again surprisingly good quality.

have a Sony A7iii and I was looking for a good adapter for my 2 Canon lenses, 85mm f/1.2 and 11-24mm wide angle lens. This K&F Concept Adapter fits my Sony A7iii well and supports the lenses. I was skeptical about the sharpness of the photos. However, this adapter really nails the sharpness. It's better not to use the widest aperture, because lenses from other manufacturers work extremely poorly. Both sample photos were taken with this adapter. The shot in Florida was taken with the wide-angle lens. The mountains are recorded with 85mm. Autofocus is excellent on a 7iii body, so I didn't see any significant difference between using the adapter and the native lens. Eyefocus works very well even in low light conditions. The good thing is that I was expecting a lot of vignette, but I was surprised to find out that this lens doesn't produce a large amount of vignette. So the bottom line is that you should give this adapter a try. It fits well, not too tight like some cheap adapters. The build quality is really good. Happy clicking!

Made from high quality materials. Precision built. It offered the least amount of resistance I've had when screwing on a new filter. It's very thin so it doesn't interfere with wide-angle lenses (as much as possible).

Using a full-frame DSLR, I made side-by-side pixel-level comparisons between shots with and without a filter. One photo was a wide angle shot of the included sky on a high UV day.

Results: Well, I didn't see any difference in color or richness in the high-UV shot, so I wouldn't buy it just for that. Most of the time, people just buy these as lens protectors (and believe me, they've saved my bacon a number of times on high-end lenses now!). As a lens protector, you want it to be as unobtrusive as possible, and I'm happy to report that I can't tell a significant difference in any test shot - color balance, sharpness, contrast - they're all so close I've never been could definitely say that every tiny difference was due to the filter.

The filter works best if you have a lens that is greater than 35mm. When the lens is too wide angle is when you get the X looking area

This small lens is a very affordable, high-quality, wide-angle lens for Sony full-frame mirrorless cameras. While it's not a new lens, I have no hesitation in recommending it. I use it on an a7 IV and it's a delight! Bottom up!

Hi use the filter on my wide angle lens. Unfortunately, at the max setting, a lens flare forms, which unfortunately doesn't look so great. At min setting it is ok (no lens flare) Processing is super. Unfortunately only conditionally usable. ML

I bought this ND filter for my wide angle lens and am very satisfied with one thing. The filter is well processed and makes a high-quality impression. But when the filter is on the lens, unfortunately the lens hood no longer fits on it because the front ring is slightly larger than the lens diameter. So far I could not see any color cast in the pictures I have taken so far.

I needed a UV filter that would match the wide angle zoom lens I bought and make it an ideal complement.
