Just one other question, is the dust in it or on it? If it's only on the surface of the rear element it's easily cleaned.

Eddy, the kit lens is V. good, but the 50mm F1.7 should be sharper at wide apertures (try testing both at F4). 18-55mm is very contrasty though, so may display more contrast than the 50mm F1.7. The best comparison would be another 50mm F1.7, there may be some PU members near to you who could help?

The Pentax-A 50mm F1.7 is a fine lens, pictures with it should be sharp and fairly contrasty. If i were you I would take some with the lens then some with another lens to provide a comparison. It should be immediately apparent if the dust is having a significant impact. I'm puzzled as to how this much dust would get into this lens as it is normally only a problem on zooms.

What do you think of the 16-45?

I think we need a few more details:

How old is it?

What lens is it?

Have you taken any pics with it, if so does the dust affect it?

How much did it cost?

Bottom line is whether or not it was accurately described and whether or not you are happy with the images it provides.

Hi Harvey, another welcome from Sheffield England and another K-x user! Fantastic camera, hope you post some pictures taken with yours.

Sounds like a bargain for someone Dave. If I didn't already have two 18-55's I would snap off your hand. I'm interested to know why you haven't used the lens? I really like mine and they take cracking images.

K-x works brilliantly with old lenses, not just the 'M' lenses, but also Takumar M42 screw fit lenses with adaptors fitted. I don't have any issues with metering as long as the eyepiece is covered. I've seen loads of posts of people complaining about the metering of these lenses, but my guess is that Pentax improved this significantly from the K-x onwards. I find I get as many (if not more) keepers with the old lenses as I do with the modern ones and the images have a different quality which works very well on certain types of shots.

Hi Charlotte, regarding the Dioptre, best way to adjust this is to look at the grid lines in your viewfinder and move the Dioptre left and right until the lines are perfectly sharp. If you can't get them sharp this indicates that your close vision is outside the range of the Dioptre adjustment and you may need other assistance as mentioned above.

I agree with you on the AF if you're shooting macro, but on other shots the AF should be sharp. If it isn't, you may need your AF fine-tuning on the camera; not sure where in the menu this is on the K-r, but I'm sure some of the other members could assist.

Best wishes, David

Any offers? The lenses will go up on ebay if there's no interest - I would much rather sell to a PU member.
