My pentax lens is all manual. Does the aperture control, mess with the function of a manual lens?

Your question does not quite make sense but if you have a rotating ring to change the aperture with the adapter you can fit the adapter and use another brand body. Your lens will be fully manual, both focus and aperture. Your camera aperture control becomes disabled.

I have used the Fotodiox adapter to connect an all manual Pentax K mount lens to my Sony Nex-6 with no problem. Be sure to set your camera to manual mode. It works great. If you keep your camera on aperture control it won't work (at least with the Sony). Also be sure to enable the release w/o lens setting.

Yes. You will get all working functions from this lens except auto-focus. The throw is long and with the focal length it should be easy to use with manual focus.

I use manual mode only with my Pentax K-5. That solves my flash problem. That also limits my versatility. I have used Pentax cameras since the K1000. This is probably my last Pentax. The K-5 is just too much to tolerate.

If a lens works on a previous analog or digital Pentax (K-mount), it will also work on the K-3. With adapters, you can use even screw-mount lenses and other formats and manufacturers lenses too. Some restrictions regarding manual apertures apply, but the camera still works with them perfectly. As your lenses are digital ones, you'll have no problem at all.

Ben - I don't think this is part of the kit lens - it does have a switch for auto and manual focus, not aperture. If you have mounted it on a Nikon DX SLR camera back, you can switch the camera to manual mode or aperture priority mode and adjust the aperture with the dial on the back of the camera. I hope that helps!

I used this with a Canon dslr, k-mount to eos adapter, and pentax m 50mm 1.7. This macro extension tubes doesn't have electronic connections so I hope your dfa macro lens has manual aperture control on the lens. Since I don't own a pentax dlsr I am not sure, but if your lens does not have the manual aperture control on the lens you may have to do a work around like I would do with my regular canon lenses when I do freelensing. (while the camera is on, set aperture and while pushing depth of field button dismount the lens thereby locking in the aperture needed - it works for Canon dslr, but not as convenient as manual aperture control) I used this with a Canon dslr, k-mount to eos adapter, and pentax m 50mm 1.7.

Hello, the lens is manual, works manually only. Please put your camera into "no lens attached" mode and continue to shoot manually on in Aperture priority mode.Thank you.

by chip do you mean autofocus, or being able to control the aperture from the camera? If so, it does not, you have an aperture ring and everything is done manually on the lens.

You'll be able to use all your old Pentax lenses. If they're screw mount you'll need to get an adapter. Good ones (Original Pentax) run about $20 on ebay or you get one from the Pentax Online Store for $30.95.I suspect the metering will work but you may have to change some camera settings. You'll have to stop the lens down, then the camera will set the shutter speed. At least that's how it works with my Pentax *istD and screw mount lenses. If you're using K-mount lenses the same applies. With my camera I do get an "in focus" indicator in the viewfinder when I use manual K-mount lenses.

No, you will have to manually set the aperture on the lens via the aperture ring.

I bought and returned lens years ago and moved on to a Nkion system. I had problems with the lens back-focusing on the K10 which had no way of adjusting the focus in camera, so be aware of this issue depending on which body you have. As I recall, the lens was new in Pentax box with warranty. I would check the return policy just in case.

The issue isn't manual focus but manual aperture. With an "autoaperture" lens, no matter what the aperture setting the aperture actually stays wide open until the shot, letting the full amount of light into the body for focusing. With a manual aperture lens, when you set the aperture, the aperture goes to that setting - reducing the light entering the body and making the image on the view finder grainy. You can avoid this by focusing and then setting the aperture, or by relying on the wide depth of field of the lens and just estimating the focus distance with the dial on the lens.

The only lens I use with this adapter is fully manual, and has its own aperture ring which functions as it would on any Pentax K-Mount camera.

No, not in auto-mode. But you can fine tune the focus when you switch to manual focus on the lens, and you leave the camera set for auto focus.This is different than other Pentax lenses that don't have the switch on the lens, this may be due to the fact that this lens was built by Tamron. I don't find this to be a big deal though, and enjoy the lens a lot!
