are you sure it will with Pentx K-3?

I have the Pentax K-5 IIs and it works fine. So I'm not positive it will work with the K-3 I'm pretty sure it will. As far as the remote itself it works great.

I don't know if it will work with the K-3, but it works with my K-30. And you have to change your settings in the camera to get the remote to autofocus. I believe it's under the drive mode settings

I suspect that it will. It is the standard pentax K mount for all of its cameras. I have used mine and it works well with them. I'm so old that I have to use a Mono-pod to help stabilize.

I do not know if this is compatible with the K50. I have used it on a K10D and my current K30. Are you aware of the Pentax Forum?

AA batteries are everywhere and chargers for the proprietary Pentax battery are not. John Blair

Hi Harry - I have a Pentax K2000 and a K5, but I use it on the K2000, I think it should be compatible with any pentax. Hope this helps!

I own the lens it works perfectly on my pentax k30 and should work perfectly on the pentax k50. I am not sure what compatibility check would claim it does not work on the k50. The lens at f1.8 is fast, it is inexpensive, it is sharp and is a my favorite lens for portraits.

I know it will probably work with the K50 since it is the upgrade for my K30. I would suggest you Google pentax.com with this question. I have a feeling it probably will work but I don't want to lead you astray!

I purchased it for my K30 and have no problem. There is a little white tab to pull forward that pops it up.

I tried to find an answer for you but I just don't know if it will. I read that they K5 is not the same voltage so I'm guessing no.

It works perfectly with my Pentax K30, so it must also work with no problems with the K50 which is practically the same camera.

Yes it will. Just make sure you get the Pentax mount version (K-mount). Note that there is no auto focus with Rokinon lenses, manual focus only. Good lens though. I get some pretty good images with with the lens on my K-5II.

Yes it will. The *istDS has a KAF2 mount just as all Pentax DSLR's up to the Pentax K5.

It fits in a standard hot shoe mount, so I'm thinking yes (I haven't personally ever inspected the hot shoe mount on a K-r... but I think Pentax uses a standard hot shoe on that model)

If it's a K mount , yes. Mine came with the correct mount for Pentax. I have a K20D and a K5.

Yes. The beauty of Pentax DSLR's is that they will accept all K-mount Pentax lenses ever produced. I myself have a 25 year old manual focus 50mm M f/1.4 lens I use on this camera.

I would think so, it fits directly on both my Pentax iST DSLR and my Pentax KX DSLR cameras and works great for the price.

I believe this will work with your K-1. All pentax DSLR lenses should be universal.
