I took this bag to store my Sony A7C2 and two lenses and it fits well. I can therefore mount either my Sony 16-35mm GM2 or my Sony 70-350mmG. Several pockets are available, there is plenty of room for small accessories.

I also took a travel tripod that fits under the bag, it is rather practical for traveling light. But a plastic clip strap system would have been welcome.

The K&F quality is top, the gray camouflage print is stylish.

I use it on a Sony 16-35 f/4 works just great. No problems with image quality and glare.

Good ND Filter for the 18-135mm Sony E-Mount Lens

Excellently made filter, comes with rigid packaging. High value for money. Mounted on the Sony 16-35 Gm lens :) Perfect.

These are so easy to use and the quality is fantastic - both the build quality and the picture quality. I can't see any colour cast whatsoever from both the CPL & ND filter. I think you would really need to pixel peep to see any sharpness difference, and even then I'm not sure there is.
Being able to attach the filters to both the UV filter and filter ring is really clever - I keep the UV on my 24-70 F4 and the filter thread ring on 16-35 F4 so it makes it even faster to clip on the filters no matter what lens I use.
Since the ND isn't variable, there's no dark X. And no vignetting at 16mm, unlike when I use my square filter set.

The downsides that I see at the moment:
- You can't replace the filter thread on its own, so if you break or lose it, you have to buy a new set. I contacted support but was asked to pay $16 for delivery of a new thread....
- The range of NDs isn't as big as a square filter system (yet) and again I'm not sure if you can buy them as singles or whether it's just part of these kits

I bought this adapter to use Sony A-mount lenses from my Alpha 58 on the BlackMagic Cinema Micro. Am very happy with it. Nothing wobbles and there is no play. The wide-angle kit lens fits perfectly and the vignetting is not noticeable (logical! APS-C sensor of the Sony is larger than the 16 mm sensor of the BlackMagic). Lenses with a fixed focal length of 35 and 50 mm fit just as well. The only thing I haven't tried is the 50-200 zoom lens, but only because I don't plan on filming with it. Overall I am very satisfied and can recommend it. Of course, it has no electrical connection to the lens, so you can't use LANC to control the focus. But that should be obvious anyway given the low price. For such tasks you use active MFT lenses or a booster, but I haven't seen any speed boosters for A-mount yet.
