Has anyone tried this K to Q adapter?

Hello,

Has anyone tried this generic looking k to q adapter?

Amazon.com : Camera Adapter Ring Tube Lens Adapter Ring for Pentax K Pk Mount Lens Adapter to Pentax Q Camera with Tripod Mount : Camera & Photo

I'm looking to get one and what caught me eye was the tripod mount that is included. So of my k mount lenses are somewhat heavy and was trying to find a way to distribute the load. I saw a post here that said the Fotodiox adapter with aperture ring had a tripod mount but didn't see it in the pictures on Amazon. Any suggestions on adapters and/or tripod mount setups are appreciated.

Thanks,
Brad

Hi, I tried one similar, it could be the same but I don't see a brand on the Amazon page. If you want my advice, avoid it for 2 reasons. Firstly it doesn't have an aperture control ring meaning you will be taking every single pic at the smallest aperture setting - spend an extra 10 bucks and get one with even a rudimentary aperture ring. Secondly mine didn't focus to infinity, which I believe means it is not holding the lens far enough away from the sensor.
Basically you get what you pay for, and with this one you aren't paying for much.

Unfortunately it hasn't arrived yet. The FD adapter I bought the next day did arrive already

It looks like the Fotodiox brand that I have. It works fine if you have a lens with an aperture ring. It shows a tripod foot, but there is no foot on the adaptor when it arrives.

I have one that looks very similar to this. And I too would recommend not getting it and putting a few more $ and get one with an aperture ring. With this one you'll only be able to use lenses with manual aperture control. I never had any issues with infinity focus and beside the missing aperture control and a slight looseness, it works good, it does its job.


Yeah I just checked my adapter and it has 4 screws on the K mount side where the picture from yours only have 3... it's probably not the same then

Correction--- If you intend to use DA lenses you need the aperture adjuster.

Which ones are well-regarded?

What's the difference?

The adapter I linked to sold by jinfinance works well and has the aperture adjuster, it also has a tripod socket.

Lenses that have an aperture ring don't need the aperture adjuster. So if you are going to use any DA, D FA, or FA J lenses (or modern third-party lenses) you need the aperture adjuster.

The bottom line is if you are really going to get into adapting K-mount lenses you will end up buying the Pentax adapter for the shutter anyway.

I bought the authentic pentax adaptor because I wanted the built in shutter, but made my own tripod mount. I bought a Chinese copy canon 100mm macro tripod mount, and lined the inside with 1/4 inch thick leather. This reduced the inner diameter to match the adaptor. Total cost was $10 for the mount plus about 20 minutes to modify it.

I have that exact one. I got it from Ebay. It was labelled as a fotodiox adapter. It has a tripod foot.

It cost me only $20 or $25 dollars, and it works wonderfully with lenses that have aperture rings. In particular, any of the zillions of manual K-mount 50mm lenses out there work wonderfully hand-held. The Tamron 90mm Macro also performs really well with it.

It depends on how serious you want to get with using adapted lenses on your Q. For casual fun use, and for a fraction of the price of an adapter with a built-in aperture ring, you can't go wrong with it.

I thought the shutter was mainly useful for fast flash photography? What others uses do you put it too?

For the record, I don't have a Q (yet?) but if I do get one at some point, it would mainly be to adapt longer lenses like the DFA 100 macro WR and the 60-250.

The link still returns an error, maybe because I'm in Canada? If I use the keywords to search I only get the Cirrus, is it the same?
