Fits the Sony VFA49R1 Filter Adapter with a filter inserted. I wish it had an option to connect some type of lanyard to attach to the extra lanyard hole on the camera, but unfortunately it does not. You can find ones on Amazon without the Sony name printed on it for cheaper, but if you want one with the name this seems to be sturdy and of good quality.

I was unsure if this would fit the Sony FE 50mm F1.8 lens… fits perfectly and appears to be the exact same lens cap model that lens comes with!

Works flawlessly - using a Minolta MD to Sony Nex adapter.Fit is perfect, and the adapter comes off the body with ease - same with removing lens from adapter.This adapter has allowed me to use all of my old MD/MC lenses instead of letting them sit around for the occasion when I haul out my X-700.

ネックストラップも所持していますが、本製品のみを常用しています。SONY α７Ⅲ+タムロン28-75mmを主に使っていますが、１ｋｇを超える組み合わせでも全く不都合なく使用できます。個人的意見かもしれませんが、腰につけたほうが圧倒的に疲れを感じにくいと思います。

Part 1 - Minolta MD to Sony NEX adapterTechnically, it slightly overshoots infinity but the issue is easily corrected by dialing back the focus ring just a tad --- Not exact but clearly better than not-at-all.Although very light due to extensive aluminum usage, the build quality and fit-and-finish of the adapter is superb. Connections on the lens and camera mount sides are tight and precise --- absolutely, zero slop. The top of the lens release button is flattened making the lens removal process very easy and comfortable.Other notes:- There are no electrical connections so focus and zoom must be done manually on the lens itself- When mounting the lens, turn the adapter clockwise till you hear a "click"- Tested with a Minolta 85mm f/1.7 Rokkor-X MD lens mounted to a Sony a6000 camera-----------------------Part 2 - Nikon Ai to Sony NEX adapterEdit: Based on my positive experience with the Minolta MD adapter, I also purchased the Nikon Ai adapter later.As with the Minolta MD adapter, the Nikon Ai version focuses beyond infinity a tiny bit. Fortunately, the same solution applies - dial back the focus ring and the horizon will become crystal clear. The build quality is impeccable and the finish is smooth and clean of burrs or machine marks. Connections on both sides are taut and precise with zero play.Additional notes for Nikon Ai adapter:- No electrical connections present so focus and zoom must be done manually on the lens.- Unlike the Minolta MD adapter, mounting the lens for Nikon adapter requires a counter-clockwise turn until you hear the "click" of the locking mechanism- Tested with a Nikon Micro Nikkor 55m f/2.8 Ai-S MF lens mounted to a Sony a6000 camera

I give this 3.5 stars. I use this with a number of Minolta MD's - 28 f/2.8, 28-85 f/3.5-4.5, 135 f/2.8 and 200 f/4. I've not noticed any light gap problem that I read about just now prior to writing this review. The only thing I find annoying is the infinity focus issue. I like to not spend much on these items but as I use more and more MD's it would be nice to have access to that very simple feature of manual focusing. Thus if not on a budget seek out an adapter that gives you infinity focus. Though I do have 4 lenses I use only one adapter, leave adapter on camera and just switch out lenses. Pic w/ MD 28 2.8.

They turn off by themselves after a fe minutes. They’re really bright though.

This is a great tool assuming you have the Sony FE 14mm F1.8 GM Lens. If you *do* have this wide angle Sony lens, this will allow you to use both 1.1mm thick and 2mm thick filters in the 100mm Kase system. This is just the filter holder kit for the aforementioned lens--you'll also need a magnetic 90mm CPL filter. Excellent product for the specific lens/use case.
