K&F Concept M42 Lens to Micro 4/3 Lens Adapter,M42 Screw Mount to Micro Four Thirds M43 MFT Fits for Olympus PE, Panasonic Lumix

I have a handful of old Pentax lens and wanted to try some out on my Panasonic G7. Had no issues with mounting and everything works great. Tried photos and video and the quality was still there.

Cheap and it does the job. Because this is for a crew mount lens, making sure that the holding screws are very tight is quite reevant, especially if your lens is a wide angle with a built in hood (like a Voigtlander 15mm). If not tight enough, the lens may rotate on the adaptor and give you unwanted, uneven vignettes. The manufacturers seem aware of this, as the adapter ships with a tiny Allen wrench tool to tighten the screws.

This is an excellent product, worth the slightly higher price compared to bargain adapters. It is solid and secure, rotating into place with a satisfying click. I can't comment on that auto focus aspect, because I use this adapter only with manual lenses. But in all respects that I'm familiar with, this adapter functions very well.

Excellent product! Shipping was a long wait, but it was worth it! Great craftsmanship, looks exactly as pictured in every detail, more than I can say about other adapters I ordered that only looked great on pictures. Pros: - Very good smooth paint finish - All metal construction - Durable (been using it over a year now) - The lens screwed in the correct way (not upside down) - Snug fit to my Lumix GH2, no jiggle. I cannot find any Cons...this is just a beautifully made M42 to micro four 3rd lens adapter. Even the product packaging looks good. Highly recommended for those looking for M42 Screw Mount Lens to Micro 4/3 adapter. Now I can finally use my Yashica Yashinon-DS 50mm f/1.9 on my GH2. (I'll add photos when I can) -Update: Over a year later & the adapter is still in very good shape! (04.24.2016)

Got some funky lenses recently through various camera acquisitions and I thought it'd be fun to try them on my Olympus EM1 Mk2, particularly the 400mm that steps up to 80mm on MFT cameras. The adapter works flawlessly! It;'s solidly built and I've had no issues or wobbling. I would not hesitate if you need to adapt some old glass to mft cameras!

Using this adapter for an old Helios 44-2 lens to GX1 and it works great. Construction feels solid, did not have any issues screwing in the lens. I've also tried another brand but they didn't attach very well to the lens. The only reason I didn't give it a full 5 stars is because as some others might have noticed, there's a very slight wiggle once everything is attached to the camera body for some reason. Otherwise this is a nice adapter without breaking your wallet, and a great way to revive older lenses. I'll probably buy a couple more different adapters from K&F.

I've really wanted to give this one five stars, but I can't. Yes, as others have mentioned - it feels solid, but it's not too heavy, and the build quality is good. My problem is this adapter's too short, so my lens focus beyond infinity. In fact - it's so short, to focus to infinity I need to turn the focus ring only a third of it's possible movement range. Which mean - my lens' focus is 3 times less sensitive. Yeah, with a very gentle touch it's usable. But it's very easy to get out of focus. I'm using an om-d EM10 ii, with a SMC Takumar 50mm 1.4

Works exactly as intended. Great for any old M42 lenses as long as you plan on using them manually. I have had no problems with the image quality out of my camera using lenses with this adapter so it gets 5 stars.

I used this to convert a Takumar 135-200mm on to my G85. I picked up the lens cheap and figured why not? The adpter fit perfectly on both the lens and the camera, picture quality is outstanding and the build is excellent. Since ordering this I've have ordered 3 more of varying sizes and have been more than satisfied.

Exactly as described, works perfectly with my omd-em10 and takumar 55mm f1.8

Adaptador robusto bien construido. Precio razonable segun mercado.

Le produit arrive rapidement parfaitement emballé, sous de multiples couches de protections. S'adapte parfaitement aux objectifs à vis M42 sur les montures 4/3 ( Blackmagic pour ma part ) Je suis ravi ! Matériel de bonne qualité, bien conçu et matériaux solides. Pas de jeu, ne force pas, très simple et efficace !

I've used various convertors over the years to fit M42 lenses to digital cameras. This one is the best made I've ever had. It's a great snug fit to the camera and the lens. No play at all in the fitments. The lens works perfectly on my Panasonic G9 - better than on the Sony A99ii which preceded it. Spot on.
