Question about Pentax 1.4xL SMC-A Rear Lens (30943) Lens Converter
Projecting front element may be an issue ?
Consider a few points. Most camera's (The Pentax is no exception here) can only use AF till f/1:5,6. With a tele convertor 1.4 times, your aperture will be twice as small. So it will become 8.
So yes you can use the converter on your Pentax, but the camera can't work with autofocus. If there is enough light, you could be able to manual focus the lens and still make a shot.
