    • The good and the bad

1) All of my Zuiko lenses are sitting too far from the sensor - Infinity focus happens when their distance scales are at about 7 meters. This is not really an issue when manual focusing, but I can't rely on a lens barrel's Infinity stop. It's a good thing the Sony a6000 has Focus Peaking and Ficus Magnification - they are absolutely necessary for manual focusing at Infinity using these adapters. 2) All of my Zuiko lenses can be focused more closely than on an OM body. This somewhat compensates the Infinity-focus problem. :-) 3) All of my vintage zoom lenses lack the resolution that can be captured by the Sony a6000 24MP sensor. They are just soft, even in the center at f/8, even though they were mire than acceptable with film. 4) Only five of my Zuiko primes are up to the task: 50mm f/1.8, 50mm f/3.5 Macro, 55mm f/1.2, 200mm f/4 and 300mm f/4.5. The rest are too soft, wide open, but ridiculously better at f8. The 50mm f/3.5 Macro and the 200mm f/4 are spectacular with the Sony a6000 (at 77mm and 308mm equivalents). 5) The OM to E-mount adapter exacts about a 1/2-stop loss of speed from the vintage lenses, much as would any extension tube. It's not a problem, thanks to good high-ISO performance. 6) Many lenses made for digital sensors are designed to deliver the light as perpendicularly as possible - to avoid the CA (chromatic aberration) "purple fringing" seen with lenses that were designed for film. I'm getting a lot of CA in the corners of the frame, but it's easily fixed in Photoshop. Note: There's no CA by shooting at f/8 instead of wide open. Lastly: I later bought a Fotodiox adapter and a Fotodiox Pro adapter for comparison and find them to be essentially identical in quality and function, so far, except the blades that engage the adapter to the camera body are about twice as thick with this K&F Concepts adapter and the Fotodiox Pro adapter, where the blades for this Fotodiox adapter are quite thin - which leads me to believe this K&F Concepts adapter (or the Fotodiox Pro adapter) would be the better choices when mounting a heavy lens (or perhaps any lens). Otherwise, the most significant difference is their weights. The aluminum and brass K&F Concepts adapter weighs 3.5 oz. The aluminum Fotodiox adapter weighs 3.2 oz. and the Fotodiox Pro weighs 3.1 oz. See photos... All three adapters have a length of 33mm, from the body mount to the lens mount, and again, they all focus well short of Ininfity. Again, the blades that engage the adapter to the Sony camera body are the same thickness for the Fotodiox Pro and the K&F Concepts, but are much thinner (for some reason) with the Fotodiox adapter. Oddly, they all feel the same when attaching lenses or when attaching to the camera body. If I had to do it all over again and money were no object, I would get the Fotodiox Pro, due to its being the lightest of the three at 3.1 oz. vs. 3.2 and 3.5 oz and having thick blades, rather than skinny blades. But the K&F Concepts comes out on top for having the best price, the thick blades similar to the Fotodiox Pro, but weighing 3.5 oz. instead of 3.1 oz. I would avoid the Fotodiox adapter due to its thin blades, where attached to the camera body - they do not inspire confidence. Again, the blades are thicker with the Fotodiox Pro and this K&F Concepts adapter. ... show more

By no means am I a pro photographer so take this with a grain of salt. I’ve been using it to adapt Yashica ML lens onto the Sony A6000. my initial thoughts after using it for the first 2 weeks are overall good but do have some criticisms. The adapter it self is solid, holding it you can tell it’s an all aluminum construction. Installing the adapter onto the camera was easy and adding the lens was a breeze. Its a basic adapter so no auto focus, no image stabilization, and no additional adjustment rings. This is not my criticism but adding that in for good measure. My criticism lies in that there is a bit of a gap between the adapter and the camera body. It’s a small gap, and I mean small, between the camera body and adapter. It’s not too big of a deal and haven’t noticed light leaks but it does cause a slight wiggle. For reference the gap between the lens and adapter is about the thickness of a sheet of printer paper. Image quality will depend on the lens itself but it does take some time to learn to use a manual focus lens. The test photo was taken to see accuracy. Toy was set 4ft away and shot at f3.5 using 75mm lens at 4ft focus marker on lens. Overall I would buy this adapter again I think it’s a great deal if u want to give new life to an old lens. ... show more

    • Built-in mechanical stop prevents DoF preview button (but can be removed)
Size: OM-NEX
Review Image by Nathan Frick Nathan Frick
If you hold the Depth of Field preview button (the button opposite the unlock button on the lens), that will manually stop down the aperture. Meaning, you are not just stuck at wide-open aperture. The only minor caveat is that you must hold this button down while you snap the photo. For some reason, the manufacturers of this adapter chose to include a stop that prevents the slider on the back of the lens from moving and thus stopping down the lens. This makes no sense to me why they'd go out of their way to prevent this very useful function. Even more confusing is why it's so easily removed. You just need some precision screwdrivers and half a brain. Remove the four screws on the silver plate, lift the plate off the adapter, and then you will find one small screw holding the stop in place. Unscrew the screw and remove the stop. Then just reassemble the back plate with the orientation shown in the image (the notched blade is closest to where the text "OM" is printed). You should be good to go! Now, if you hold the DoF preview button down while snapping your picture, the lens will stop down to whatever aperture you have the ring set to and you will be able to use the lens to its fullest potential. In auto mode, the camera will automatically adjust exposure once the aperture is stopped down. ... show more

    • Adapter fits perfectly on my Sony a6000

Adapter fits perfectly on my Sony a6000. Looks and feels very well made. For a low investMent it allows you to use your legacy Minolta Rokkor lens. You can expand your lens collection inexplicably with those legacy SLR lens. I currently have a Minolta Rokkor MC 50mm and a Vivitar 85-205mm zoom; both fit perfectly to the adapter and the adapter to camera base. You just have go back to your roots and manually adjust all settings. Focusing was easy. I did notice a lag in the viewfinder when adjusting the f stop using the Vivitar zoom, but not difficult to get true view before shooting pics. Rokkor 50mm works great. Just took a couple early morning pics with my Minolta 50mm. 1/320, ISO 3200, and f 1.7 (manual settings) Pic as shot and I didn’t do any editing/corrections. Enjoy! ... show more
