Telephoto adapter: Has anyone used a telephoto adapter with the Pentax DA 55-300mm lens?

Hi, i used this lens with a Promaster 1.7x and a Tamron 1.4x Teleconverter, both let the camera (K7 and k5) focus with the lens, but i would only recommend it in occasions with a lot of light, the TCs cut down light and AF can get pretty sluggish.

Dear Gentle Giant,Check if your lens can attach to a newer Pentax camera first. You can do that in a local shop. As Pentax uses PKA type mount and this adapter accepts that. I think some old Asahi lenses had screw or different mounts.Keep in mind though, that you will only be able to use the camera in Aperture priority or manual modes. And that focusing and f-stop selection is done manually.

The bundle I purchased did not have a telephoto, but it did have a wide angle/macro lens and there is an additional adapter ring 9labeled 49-58mm0 that needs to be placed on the bottom of the lens before attaching it to the mounted 18-55mm lens that came with the camera. It is the same with the telephoto lens adapter that came in my package. By the appearance of your package in the email, I believe that you received these adapter rings.best wishes

I have used it with my Nikon d5100 and up to a 55mm-300mm lens. It worked decently well for a compact tripod to take on the hike in my camera bag. I would suggest a remote release with it though.

Try attaching the lens adapter to the lens before attaching it to the camera. I have kept mine on my Pentax 50mm lens to be apart of the lens itself.

With the proper adapter there should be no problem but I have no experience adapting Pentax k lenses to Canon bodies.

Not Recommended. The image formed by the lens does not cover the full 24x36 frame resulting in vigneting (dark corners). Exceptions: Some users report that the DA 40mm does cover the full frame and that some DA zooms at least at some focal lengths also cover the full frame. i find this site extremely helpful explaining which lens can be used for which systems...good luck The Pentax Camera Lens Compatibility Chart Read more at: http://www.pentaxforums.com/forums/10-pentax-slr-lens-discussion/186379-compatability-modern-pentax-lenses-old-35mm-film-pentax-bodies.html#ixzz2sARZbYXF

I have this lens, it's very nice. I bought it for my Pentax K3 and recently started researching how to adapt it to a Pentax Q7 so I purchased a Pentax adapter K for Q. From what I read the adapters work but you will have to manually focus since there are no auto focus contact points on the adapters. I believe the same is true with all the less expensive adapters.

Yes. It looks like this lens:Pentax DA 18-55mm f/3.5-5.6 AL II Lens for Pentax and Samsung Digital SLR Cameras

No, this is for Samsung DSLR which were re-branded Pentax DSLR. Or from the joint venture that was mostly Pentax design. That being said this would work with an adapter but you would lose autofocus etc and can only use in Aperture or manual mode

Hello, kkiriluk. I'm sorry to say that I can't verify that the Sigma lens works with Pentax cameras. I have a Nikon D40x and it works splendidly. It is the best lens I have purchased for it. Best of luck finding a fellow Pentax owner who has used it.

I have the same lens & teleconverter and it works perfectly. Good luck hope you enjoy this setup. Wayne

I have tested the Canon 1.4x teleconverter and it works well. AF is also listed as possible even for the Canon 2x teleconverter. Listed here: http://www.bhphotovideo.com/FrameWork/charts/canon1_4xExtender.html http://www.bhphotovideo.com/FrameWork/charts/canon2xExtender.html Here is the list for the Kenko Pro 300 teleconverter which is a highly rated teleconverter and it is compatible with the the lens as well for both the 1.4 and 2.0: http://www.kenkoglobal.com/pdf/TELEPLUS_DGX_series_CompatibilityList.pdf. Obviously, things will be more challenging with a 2.0 teleconverter but not impossible. It will all depend on how steady you are with the camera(tripod), you ability to focus manually, and the amount of available light etc.

Generally the answer is yes. However today i discovered that I have a Sigma 28mm lens that mounts on every pentax film camera I own, but that lens will NOT mount on my Pentax K-x DSLR. I am trying to find out why, and if that can be fixed, and I am close to ordering a K-30 myself, and am curious if it will mount to that Sigma lens!

Some of the old lenses will not focus to infinity on the Pentax DSLR's. I was disappointed in that. My 135 mm, the 105mm and my 200 mm Super Takumar lenses would not focus at infinity. You will definitely need the modern D, DA or DAL lens to fully use of all the camera functions.

Not without the LA-EA1 or LA-EA2 Adapter. The 55-300 is an "alpha" mount lens and the A3000 has an E-mount. The closest you will get to a "native" e-mount zoom telephoto for this camera is the 55-210 zoom, which I have found to be a very good lens used with an NEX-5n camera. The 55-300 is an excellent, reasonably priced alpha mount lens, but it does not have "optical steady shot" built-in like the 55-210 E-mount zoom telephoto, so in addition to the cost of the adapter, you would need to use higher shutter speeds / higher ISO settings to minimize image blur when hand-held, particularly with lower ambient light levels.

I have both the 150-500 and 50-500 Sigma lenses (A-mount) and it works with both of them. I use them on Sony E-mount cameras with a Sony A-mount to E-mount adapter. IS works with the teleconverter but AF does not. All other function work. This converter works especially well with these lenses for wildlife subjects.
