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 £££.

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.

Does the job, seems a bit bigger than it really needs to be IMHO, but doesn't affect performance so not complaining!

Like all the other K&F Concept adaptors this is beautifully constructed and a snug fit. I only buy this range now.
