[0.465 lb] First of all, here is the equipment I'm using to test it: Nikon D7000 (16MP), Nikon 18-200mm VR (not VRII), a Konica 80-200mm f/4.0, tripod, and Vello wireless release. Summary: Definitely worth the money if you have a Konica AR lense you want to use. Test Technique - I mounted the D7000 on a tripod and used a Vello wireless shutter release to reduce any shake. I focused the camera manually using a loupe on the display with the display zoomed to maximum. The subject was a tree about 100 yards away. I focused on the leaves. I set the Konica lense to 140mm to give an equivalent zoom length of 200mm (taking into account the adater's lense) and compared this shot to the same shot using Nikon lense set to 200mm. I then opened the raw images in Photoshop and zoomed to 400% where I could see individual pixels. After careful examination, I could see no noticeable difference in the two shots. I looked at the sharpness of the leaf edges and chromatic aberations about 1/3 out from the center of the images. I realize that chromatic aberations and sharpness issues will be more obvious at the image edges, but the best spot to examine the leaves was not at an edge. Also, the D7000 is only 16 megaixels which limits how far you can take my test results, but in you have an AR lense you want to use, the cost of this adapter is a whole lot cheaer than buying a new lense! Two grips I have are the the adapter came with a front cap but camera body cap. That makes no sense since either side on the adapter lense can be damaged! Also the pouch could be made out of better feeling material, especially considering it ships with only one side capped. However, I have an extra body cap so I'm using it on the adapter. But I'm buying it for the adapter, not two caps and a bag so I'll keep it. It just gives a sense of cheapness that isn't really deserved.

[0.465 lb] Adapter is very smooth and fits all my grandfathers old Konica glass on my Fuji XT-20. So psyched about using all this old glass!

[0.465 lb] I have previously owned and used many adapters, including a number from Fotasy. Most of them worked perfectly well, but in particular my Fotasy Konica AR-Nikon Z adapter would not click into place on the lens end. That meant with heavier lenses, I always felt at risk of the lens falling off; if the lens had a stiff aperture or focusing ring, there was an even greater danger of it detaching, and other old adapter ended up unscrewing a lens from its helicoid, a total disaster in the field.

No such problems with this Kipon. It is solidly constructed, the mechanics feel springy and everything is well machined. There is very minor rotational play, but the lenses click in securely and the release button is nicely sized and easy to press (cheap adapters often have sharp and nasty levers that you have to impale yourself with to release the lens).

If you want an adapter for Konica to Nikon Z, this is the one to get, and it is absolutely worth it for the quality of the design and build. I would definitely look closer at Kipon's other offerings for future purchases.

[0.465 lb] No play at all between the lens and the adapter like you can get on some cheaper options. The adapter also feels and looks high quality, and doesn’t draw attention to itself.

[0.465 lb] It's solid, lightweight, cheap and it can focus to infinity.

[0.465 lb] All metal with very good finish. Easily used with excellent focal range to infinity as designed. Don't let those sharp, Konica AR lenses sit on a shelf....

[0.465 lb] This item, adapting my manual AR (Konica/Adaptall2-K/R) lenses to my Nikon D5100, is a perfect and secure fit. I was surprised that it even came in its own soft case (really saves stuff from damage in a full camera case!). Since I am using it for long distance terrestrial and astronomy application it couldn't be better! (Well, that being said, I wouldn't mind it being a little larger in outside diameter and knurled, but those would only help cosmetically because my lenses are so large).

[0.465 lb] WELL BUILT WITH ALL METAL CONSTRUCTION INCLUDING A COATED LENS (FOR FOCUS TO INFINITY); EASILY DEPLOYED, WITH EXCELLENT RESULTS. BRING THE LEGACY LENSES OFF THE SHELF AND INTO USE WITH CONFIDENCE.

[0.465 lb] With the help from B&H online chat, I was able to get my questions answered which helped me purchase the adapter. This meant I now have the use of several great lenses I otherwise could no longer use. I'm very happy!
