Pentax smc 1.7 focus problems
on start up set your focal length to 50mm. that is for your shake reduction (which you can turn off if you don't need it). at f1.7 you will not get as sharp an image from that lens as you will when you stop it down a couple stops. (where it will blow away the kit lens). at f 1.7 you will have ...

I have just been trying out a smc 1.7/ 50mm which I bought a few months ago. My problem is the photos dont seem as sharp as photos taken with the kit lens auto focus which I thought would be the oposite. Should be at least as sharp at F4 (and maybe a bit wider as well) if the lens is clean and in go...

Pentax smc 1.7 focus problems
The window you refer to comes on at start up right? If so this is the camera asking for confirmation of the focal length of the lens in this case 50 (setting can be changed using the left & right keys on the ring around the OK button). This is for updating the camera as to which lens is in use a...

The rule of thumb is that lenses perform best two stops down from open aperture. In reality, with the 50mm you will have superb performance at most apertures apart from the two extremes. Just select the aperture you need for DOF considerations.

Random Cleaning mode
After seeing Duncan knifton's problems in another thread it reminded me of a bit of a funny I have with my K10D. Very rarely, it will randomly put itself into sensor cleaning mode. I'm not touching the camera at the time, it's switched on, but has put itself to sleep and in P mode on the dial. Wi...

Random Cleaning mode
Thanks for the feedback guys. Given the rarity of it happening, I doubt if it would be worth sending back. The chances of it happening whilst it's away being examined are slim indeed. I'll just live with it. Duncan
