have a few of these K&F adapters for mounting various vintage lenses on my cameras - I use Canon and Fuji ASP-C and M4/3 cameras and they are brilliant on all 3. Great price, well made and they work really well.

Very good value for money Tamron Makro 90mm f2.8 Nikon mount on Fuji x-t20. Loss of autofocus, difficult but achievable focusing, see photos. Don't deprive yourself of this with quality goals

Since I can use old Tamron and Konica lenses I have to admit that it works on the Fuji xt30, of course it depends a lot on the type of lens used. In my case, the Konica lens works better than the Tamron lens, but I must also say that the second is a zoom while the other is fixed and with the latter I take sharper and more contrasting photos.

Looks just like the disposable fuji cameras. Lightweight with a screen on the front and back. Okay clarity, but not great pixels. Works well for my niece to record videos.

ordered the adapter to use a vintage Tamron mirror lens (5.6/350 mm) on my two Canon bodies EOS 5D mkIV and EOS 1Ds. Since both cameras are not listed in the compatibility list of the item description and one often hears (with other adapters) that the camera mirror can no longer move freely and therefore error messages or damage to the camera occur, I was curious whether that would also be the case my two cameras would work. It works out. The adapter is also seated without play, attaching and detaching is easy. It was clear to me beforehand that the focus and the time setting had to be made manually. Unfortunately, the invoice must first be requested from the seller, but it came within 24 hours as a PDF by email. However, it is an import invoice without deductible VAT and in the "worst case" the tax office will still have import sales tax when it is submitted. At the price of the adapter, however, that can probably be gotten over.

The lens is great. For my type of photography (I mainly photograph people, see also Instagram 'uwe2756') it replaces all other lenses, with a really great imaging performance (open aperture). However, it has its price. And it's big and quite heavy. When I'm shooting and concentrating on the model, it's not that important anymore. So far I've had three lenses in my bag, the Tamron 28-75 f2.8; the Tamron 70-180 f2.8 and the Sony 85 f1.8. Now I only have this lens (on my A7 III with battery grip) with me. I am absolutely delighted and can recommend it unreservedly.

I bought this part to be able to use my Lensbaby composer on my Fuji cameras as well. The adapter makes a valuable and well-made impression. It looks stable and works as expected. Since everything is set manually on the Composer anyway, I'm not interested in the lack of the autofocus story. Very useful for me at this price.

I have a Sony A7III with some of the Tamron lenses they recently released, 67mm thread on the dUKx. I first used the ND on a daylight midday shoot and was amazed by the results. The best part is that I can choose the number of stops I need to make the zebras disappear with ease. Ease of movement and robust construction. Only negative is that the sun visors don't fit after turning on the ND. Not a deal breaker but be aware.

EDIT: I also took it on a trip to Lake Tahoe and it came in really handy for longer exposures and more sky contrast. Awesome and so easy to use!
