Worth buying an adapter for this lens?

I found this camera and lens in an old box. I am wondering if it would be worth it to buy an adapter to use it on my K20D? Also, does an adapter affect it's speed?

Thanks gang.

Stock photo below, but the lens I found is spotless and the blades are crisp and clean.

It will end up costing you a few hundred dollars. Oh, the adapter is only about thirty bucks....but it will lead to purchasing more M42 lenses. They're like Lay's potato chips.

You may send the lens to me if you wish to save yourself from this horrible fate.

Nice lens, make sure there are no issues with the mirror clearing the back of it. (Some Fuji M42 lenses interfer...)

The Fuji lenses do have a following. Not sure if that's one of the more highly regarded ones though...

This is the entry level fujinon, does not come with famous EBC coating. There is also no pin poped out too, kinda sweet. So it can be easily adapt to PK mount.

This lens does not have problem with mirror. As far as I know, only 16mm fisheye could have problem with full frame Canon and Kodak.

It's very personal opinion on IQ.

The lens itself may not worth the adapter. If you like to play old manual focus m42 lenses, it's a good start.

You know, the more I looked into it, it was purchased in the late 70's from K-Mart no less. Not understanding how this lens's numbers convert over to a digital camera makes me wonder if I should go ahead.

If this will truely operate at 2.2 55mm, I might give it a whirl. $30 for an adapter isn't that much especially if it makes it possible for future screw mounts.

By the way, this lense has a pin sticking ut the back for aperature control. Not sure if that will be a problem.

Please, if anyone can tell me if it remains a 2.2 55mm when mounted to my K10/20D let me know. This thing is clean!

Thanks,
Tom

The aperture actuation pin is normal and won't cause a problem. The maximum aperture will still be 2.2 on digital, but the crop factor will apply to this lens just as to any Pentax lens. The 55mm will be 55 x 1.5.

The stick-out pin is no problem if it can be pushed back. The pin I mentioned on most of the Fujinon EBC lens is on the edge of the aperture ring to transfer the aperture reading to the camera. That will cause problem.

The lens will become 75mm F/2.2 on pentax DSLR. Perfect for portrait. So go have a try and I can ensure you better results than the kits lens.

A small thing is the photo taken by this lens MIGHT be a bit warmer due to the some element in the coating. There are enough discussion on how to reverse it. All my Fujinon EBC lens are ok but I have a 50/1.4 without EBC coating is a bit yellowish.

In terms of adapter ring, go find a original Pentax one. The most common version comes with blueish plastic bag. Maybe someone on the forum have a spare to share.

Yes, it definitely operates at f/2.2 - which is to say, slower than the Pentax 50/2 or 50/1.7, neither of which cost any more than the $30 adapter you are considering. And yes, it truly operates at 55mm, which is to say, the field of view *any* 55mm lens - including the kit 18-55 at its longest - provides on digital (on the wide side of what might be considered useful for portraiture, on the long side of what is otherwise useful for most indoor use). Neither f-stop nor focal length change just because the lens came from a film camera. A 55mm lens is always a 55mm lens on your camera no matter where it camera from (even though 5mm on your camera might be different form 55mm on a film camera), and f/2.2 is always f/2.2 on your camera.
