I think you can set the AF button on the back of the camera to do this.

Thanks for your comments. i am concerned because I have had my camera lens checked by Pentax and after backfucusing adjustments and the second time front focusing adjustments and thirdly told it's ok. The focusing is inconsistant - sometimes it's incredibly sharp and others soft and not centered. Settings the same of course. f2.4,iso 100 ,good day light, center point. Could excessive play cause this inconsistency?

I get this all the time with my DS, inconsistent focusing with various lenses. I think it's the camera. What camera do you have.Thanks for your comments. i am concerned because I have had my camera lens checked by Pentax and after backfucusing adjustments and the second time front focusing adjustments and thirdly told it's ok.

I don't have this lens, but I used to have the excellent 24-90 zoom. It is normal for that lens to exhibit alarming wobbliness and yet the pictures were always fine.
Perhaps both had the same lens designer.

I have the same lens George (24-90). Great pictures from it, though it can be a bit disconcerting when you point the camera at the ground and the lens "auto-zooms" by itself at alarming speed !!I don't have this lens, but I used to have the excellent 24-90 zoom.

You are certainly right that digital enables us to examine our photos in a lot more detail than we ever did with film.
If I ever get round to scanning all my old negatives i am sure a huge amount of "good" pictures will be dismissed by me as out of focus !

Chris I totally agree with your point about the MF screen. I was very surprised when I had focus issues when I first got my 10-20 zoom which were resolved by using the multiple focus points. Personally I don't find them any hassle to use as I can use the thingy on the back of the K100D to set the point to use.
Sad individual that I am I took shots of a brick wall at about 12-15 feet and could just about detect a difference in focus depending on where the focus point was set. The tell tale is often revealed when you hear the focus resset as you change focus point.

Are you talking about the Sigma 10-20mm which has a maximum aperture of f4 ? If you are 12 feet from the brick wall, at 20mm focal length you have a DOF that extends from 6 feet to 44 feet! How were you able to tell the difference in focus ?Chris I totally agree with your point about the MF screen.

To add to what Chris has said regarding using autofocus. I use the method he describes of centrepoint focus and then re-frame. With the Pentax lens you have (18-55), after the auto-focus has locked on(in single AF mode) you are still able to turn the focus ring to "fine tune" the focus if needed.
It might be worthwhile doing some experiments to see which is better , the AF or your eyes !

The viewfinder magnifier O-ME53 will give a 1.2x magnification. This is useful if you do a lot of close up work, but you will have to shift your eye around slightly to see all sides of the frame and wiewfinder displays.
The split prism screen is a much better option in my opinion, and I have used both.

Hi
I love number 1 !! The angle, the subject, the look in her eye..... great shot.
I am afraid it goes downhill for me from then on. Number 2 is holiday snap-ish in my opinion. Not sharp and the Leaning tower of Pisa on the left doesn't add to the scene.
Number 3 is also unsharp (perhaps 1/90 was not fast enough at your focal length) and the cut off chimney and lamp ? at the bottom dont help either. I always find old Abbeys wonderful places to visit but find my photos of them always lacking something, dont know why.
ps. did i mention how much i liked number 1. ?
