BELL and Howell 28mm Lens on K-x

Hi All,

I'm new to the DSLR scene so any help would be appreciated. I've had a K-x for about 3 months now and have been getting on great with the standard 18-55mm and a Sigma 70-300mm Zoom that I bought shortly afterwards.

I wanted to try an experiment with a f2.8 lens and bought a cheapy on EBay which is a Bell and Howell 28mm that will do f2.8. However, although the lens fits fine and I can see through the viewfinder okay, the camera refuses to take any photos when I press the shutter release it does nothing. The lens manually focuses okay and seems to work otherwise.

I'm sure that this is just me being thick but can anyone help?

Cheers,

Stephen

This link should help you as well including stop-down-metering (Green Button)

or

Page 284 of your K-x manual.

Cheers!

Thanks a million guys, I knew it had to be me. I assumed that because it fitted and I could focus then the camera should be able to take the picture. That'll teach me.

Thanks again.

I'm curious: All the B&H lenses I've seen are for 16mm or 8mm cine cams, and won't focus to infinity on a Pentax SLR. Can you describe or post a photo of yours? Does it have a Pentax PK bayonet mount, or an M42 screwmount with adapter, or what? Can you focus to infinity or are you limited to closeups? Thanks!

I'm away for a couple of days but I'll let you know the outcome when I get back to my camera at the weekend.

Cheers,

Stephen

Hi, Here are a couple of pics of the lens. It has a bayonet connection. Tried it out earlier on today and no problems focussing to infinity.

Hope that helps.

Hmmm, looks like on of those generic Chinon- or Cosina-made primes, sometimes seen badged as Sears or whatever. Usually pretty decent optics. Enjoy!

Hi, I actually got shot of the lens months ago, I just wasn't using it (in fact, I've got a K-r now too instead of the K-x). There was nothing wrong with the quality of image with that lens though pretty sharp for an old boy but I spend most of my time with either wildlife or astrophotography so the longer lenses get all the use. If you can get one cheap then I'd say go for it.
