FotodioxLens Mount Adapter - Pentax K Af Mount (Pkaf) Dslr Lens To Sony Alpha E-Mount Mirrorless Camera Body With Built-In Aperture Control Dial

hey actually i would like inform about this product fotodiox pro IRIS lens mount adapter this is not giving me full view with canon lens because i have canon lens 24-105mm and my camera is sony a7c so is there any option can i exchange with the right adapter plz let me know

Used this to attach my grandpa's Canon 50mm F1.4 to a Sony A7iii. The image is softer than a newer lens but has a smooth filmy look. Love it!

This was bought to allow me to experiment with Canon FD lenses on my Sony a6000. The mount fits both camera and lenses very accurately and smoothly. Highly recommended!Incidentally, using these lenses has been really interesting. Obviously there is no electrical connection between camera and lens, so that aperture and focus need to be set manually. Focus peaking helps with the latter and it's hardly a chore anyway. Viewed on 13.5" retina computer screen my impression is that the legacy lenses are noticeably sharper than the 16-50 kit lens that came with the camera. Whether they are better than Sony high-end lenses I have no idea; but I have them and they work! I have a 50mm (35mm film value) macro lens that allows sharp focus on the stamen of a crocus while throwing out of focus the petals in the foreground and background! Amazing!

Do not buy this adapter. I bought this lens the other day, the Carl Zeiss 35-70mm G Contax lens. As can be expected I was excited to fit this onto my Sony A7. After doing some (quick) research I settled upon this product and all I can say is, WORST DECISION EVER. I have literally had this lens about 3 and a half hours, and in that time I have not been able to get one clean shot.I own a few Zeiss lenses, and I know of there LEGENDARY build quality, and optics but paired with this adapter I have already put the lens up for sale. The adapter is hard to get on,the focusing ring is stiff and wonky, the lens feels like its crooked and going to fall off, and to make matters worse, it now seems to be stuck onto the adapter and can't come off. I don't know what to do as I want to sell the lens, return the adapter, but don't want to break anything. All I can honestly say is STAY AWAY from this product. There are way better adapters that cost more money, and are probably worth the extra money, but as for this, this has been a DISASTER purchase. I just hope i can get this removed and sell and return both products.Again i repeat. DO NOT BUY THIS PRODUCT!

I also own a few alternatives to this adapter and I can say that, while expensive, it's about as well made as it can be.After a few thousand photos the aperture open/close ring (I use this for every photo) still works perfectly with no slop and the mounting surfaces show no wear either.The tripod foot is very strong and can be completely removed (in two parts) if it's getting in your way.If I you just need a tube to mount a megazoom (not a canon FD) onto your camera I would say get the cheapest you can find, but if you have big money invested in a Sony camera and a lot of FD lenses then spend the extra and get this.

This has allowed me to use 40 YEAR OLD lenses from my old Mamiya Film camera on my Sony a6000. Not perfect as there is tiny movement but not really an issue so far. Saved a lot of money adapting old lenses although for my particular needs I can only use Manual Focus as there are no electrical contacts. Having a great time with the old glass which I have kept immaculate and are all metal construction and well made. For the price this is a great buy.

Fast delivery from US, well packaged and competitively priced at £32.96. I have ordered 2 of these adaptors with an intent to buy 2 more at the later stage. These adaptors are the latest offering from Fotodiox and they seem to be very well made, nice weight and a quality finish. The aperture lock ring [intended for use with Nikkor G range of A/F lenses] works smoothly across the full aperture range. both interfaces fit smoothly and without play when locked in. The lens lock has that nice positive click, when the lens is locked.I use 3 NEX 5N / 5R cameras with 13 of my old Nikkor manual and A/F lenses, some purchased way back in 1975 .... and unlike the cheaper adapters supplied from Chinese or Hong Kong outlets ... this adapter actually does allow Nikkor lenses to focus at infinity. A friend of mine has the latest NEX to Nikkor Novoflex adapter, that costs 5x as much as the Fotodiox adapter and I would be a liar if I said that Novoflex adapter is not better made. But the difference in weight and in workmanship is very subtle and it is definitely not worth the ridiculous price hike.
