Not sure about this product, it looks good and seems well made but it is a very tight fit in the camera mount, a lot tighter than the Sony lens I bought with the camera. I haven't had the courage to turn it to the fully locked position but have tried a couple of legacy Pentax lenses with it and it works fine, albeit not properly locked in mount !!

You can`t go wrong with this adapter, especially considering it`s price. I`m using it on the Sony a7.+ Allows infinity focus+ Great build quality+ No wiggle, fits perfectly+ Cheap- You can`t use AF (I was aware of this, the automatic ones are at least 5 times more expensive)- Reflection on some photos: as the inside of the adapter reflects some light onto the sensor, causing ghosting (there are tips online how to prevent this)Overall I`m happy with the adapter. Get some cheap old lens and save yourself some £££.

great solid well engineered product, couldn't be better. im using it to fit pentax k prime mount lenses to a Sony nexfs700ek pre video camera.this works very well , of course there are no auto config you have to set iris and adjust yourself likewise focus but if your any sort of videographer or photographer that wont present a prob . works through infinity. does exactly what it says in the ad or on the box

After trying several different makes of adapters to fit a collection of legacy Pentax k-mount lenses to a Sony A7, Sony NEX 5N and Sony A7II have finally found one that works perfectly.The manufacturing quality and finish is first-rate, infinity focus works, and it can be attached and released with ease to all the E-mount cameras we have. Highly recommended.

The adapter I received has a big issue - the black paint they use on the inside of the adapter is shiny which causes reflections and lens flares and a subsequent loss of contrast. The paint should be a flat matt black to stop this. Such a pity as the adapter is well made and well priced.
