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.

I used this to put the lens from my dad's old film OM System Camera onto my new OMD 10 Mark 2. It's a solid, quality feeling, product and worked just fine. The old lens are very valuable so it paid for itself very quickly. Only thing to consider is the mm length nearly doubles from the old system to the 4/3 camera....So your old 50mm lens becomes nearly 100mm. I don't know why, I'm an amateur but there you go.The adapter feel very good quality and does the trick beautifully.

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.

A well-manufactured bit of kit that fits snugly to both lens and the camera body, and allows me to use an old legacy lens (Oly 50mm) with my EM-1. It allows for manual setting of the lens, which is fine, and gives good results. Cannot really fault it for the price that was paid, and happy to be able to use old lenses with a modern body.

Bought this adapter to work with my Olympus EM5 m2 camera so I could use a old OM fit Olympus manual lens 300mm . It works great . Well built. Smart looking . Would recommend.

I've been using this for a month now. The fit to a GH4 is very good. I knew in advance that the automatic features on my lenses would be disabled but that said I have used DX, G, D, and AI(S) lenses with this adapter and they all work. Obviously the crop factor for the DX lenses is less noticeable, but noticeable none the less. My go to lenses with this are my AI-S lenses 26, 50 and 105. That leaves a hole at the wide end and I think a M43 12 or 14 prime should fill that gap. To be blunt the speed boosters with great lenses are less impressive than good primes. The throw on the aperture control is tiny, but once you are used to it, no problem. I found not have the aperture feedback scary at first, but now it's one of those challenges that focuses your thinking. On the GH4 you have to set the menu to "Shot With No Lens". I also disabled the shutter to be safe (set to electronic shutter). For lens hacking it's a little awkward (the Canon mount is better for this) but it is doable. This adapter is a very good deal.
