Works fine now but originally my Helios 44-2 was mounted upside down. At front of the adapter three screws needed to be loosened to rotate the mount 180 degrees. I did that but had to find out what sort of screws they were. Not immediately apparent. Discovered it needed a T5 star pointed bit to do the job. Hope this helps any future buyers.

These adapters are amazing the the price, with my OM lenses it feels like part of the orig lens, at least as much as an adapter can do, I love them.

Does what it says on the tin. Don't particularly appreciate being hounded to leave reviews.

I bought this adapter to mount an OM lens on my OM-D E-M10 MkII micro 4/3 camera. The Olympus own-brand costs £199 so I tried this as there was no comparison in the prices. I am delighted with the adapter. It is of all-metal construction and both the lens-facing and camera body-facing surfaces are very well machined, so both attach smoothly. There is no rocking at the joints with this combination and the images are excellent. The only point to bear in mind is that focus and aperture must be adjusted manually, as there's no auto-linking across the adapter. This is, however, no chore at all. Why pay more when this unit should suit most users?
