This adapter works well, and has opened up a range of new lenses for my micro four thirds camera. The only knock I have against it is the aperture adjustment ring. Why does it have one? I prefer the one on the actual lense because it says what f stop I am using. Also, when removing the lens from the adapter, it is hard to grip and I am tempted to turn using the aperture ring. Which I don't think is good. It almost feels as though you would have 1 ring per lens, because removing the whole assembly is going to be easier that removing just the lens.

Worth its price, metal, good workmanship and fitty. The inner surface of the black paint semi-glossy, in the future should have a matte black. I recommend the product.

Works well with my G80 and G7 I can use all my Sony lens with manual focus only but very handy for the wide and the tele as Panasonic ones are mega bucks its a simple unit nothing can go wrong with it unless you drop it of a cliff.Sony lens on a Micro 4/3's

Extremely well engineered converter with good heft, a solid feel and a pleasing to use aperture ring. I can now use my old Nikkor lenses on my M43 camera, so I'm happy. My only slight criticism is it didn't fit on my camera initially. Close inspection revealed that the two tension springs were too strong but after a little fine tuning it now fits perfectly. I'd recommend this to anyone wanting to use their Nikon lenses.

Surpassed expectations.I bought this without much real belief it would work. Just obtained a tamron 150-600 G2 lens for my older Nikon D300s and started to wonder if I could use the lens with my Olympus Pen-F which has much higher pixel rating and a crop factor of x2. It also has inbody IS.This works absolutely brilliantly! Obviously needs manual focussing which is assisted by the Peak focus tech in the olympus but has now given me an equivalent of 1200mm reach.Very well made and an absolutely snug fit to both the lens and the camera body.

For less than 20 quid I can mount my Nikon lenses on my Lumix amazing. No electrical contact between lens and camera but for this money you won't get that. Nice fit no looseness. Really pleased.

Good quality, solid metal construction, smooth turning of aperture ring from OPEN position (widest aperture) to LOCK (smallest aperture). The only reason for not giving the fifth star in my rating is because the aperature ring does not close my lens completely to its smallest aperture f22 - the highest aperture setting appears to be about f16, therefore my f1.7 to f22 lens cannot be set at f22. The aperture control ring has a total of 5 stops: OPEN (largest aperture setting), LOCK (smallest aperture setting), and 3 click stops in between. Of course you can choose any setting between the click stops as well. There is a less expensive version of this type of adaptor that has stops marked from 0 to 7 (8 stops) which handles my f1.7 to f22 perfectly from largest aperture f1.7 to smallest f22. This lower priced product does the job nicely but the thing that I do not like about it is that the aperture control ring is not smooth at all (probably no ball bearing). The smooth aperture ring product of this review does work for all stops on my 28-80mm Maxxum zoom lens.

I am extremely impressed with the quality of these adapters. I have 5 now, and while they might be a couple of pound more expensive than some others found on ebay, when you hold them in your hand, you know you're getting good value. They are all precision machined metal, with high quality finishes, and the control rings on adapters that have them, have a very satisfying action to them.For dumb adapters (ones without electrical contacts for modern lenses), getting anything more expensive than these adapters is a waste of money. They do everything you need and couldn't possibly feel more sturdy or satisfying to use in my opinion.Note: if you want an adapter for a nikon ai lens, the nikon G adapter also works, the aperture ring just doesn't do anything. I use the one adapter for both ai and g lenses.

Have 4 of these k and f concept adapters for nikon lens and the following camera ends ... sony e, m43/mft and m42 screw. They all seem well made and are a good snug fit. No looseness. Excellent.
