Lens creep on 18-250mm
There seems to be some confusion here. Are we talking zoom or focus creep?

Help! K7 Auto ISO - how to turn off?
Thanks, that appears to have done it. I really think some of the other brand cameras have it nice where you can save your settings on the card. Its been a week with the darned thing back and I'm still playing with menu items when I find the camera behaving differently than I remembered. Thank...

Photomatix + GX-20
Hi, I am not sure if I can ask this question here but I am having trouble with photomatix 3.2.9. All of a sudden when I choose process the final processed image is coming out nothing like I had it in tonemapping. Has anyone else had this problem and found a fix? I am going to try going back to ...

Sensor dirt, DA 12-24, and Kx
This came up a . I thought it was just sloppy lens-changing technique and my incompotence. But I've just returned from a week walking in Herefordshire/Mid-Wales, and almost EVERY SINGLE photograph I took with the DA 12-24 had sensor dirt on it. I cleaned the sensor every morning and evening with...

Sensor dirt, DA 12-24, and Kx
well there was definatly "stuff" on the sensor that I removed each time (could just about see with naked eye) - and test shots with different lenses had dirt until cleaned. I don't know if the zoom action of the (12-24) lens was blowing it back onto the sensor each day though. The higher the F...

Pentax K7 Unsharpness
For what its worth: Just come back from Safari - Last year took the K20 and caught some good images (11 made it to the PPG!) This year, took the K7 and must agree, the results were nowhere as good - quite disappointing in fact. Deliberating about keeping the K7 and maybe buy a second K20? :(

Now you know why I sold my K7, I have had some good photos with it but is was so inconsistent with focus and and exposure issues I got fed up with it, I prefer the K20, but I have moved on and not looking back, Jack.

hi is this using afs or afc mode, i find the k7 struggles using afc, it just doesnt seem to snap in to focus like the k20.

For goodness sake, do the AF adjustment. It's the first thing you should do. You can't possibly make it worse (unless you are unusually inept, and I very much doubt that you are). :lol: G hi is this using afs or afc mode, i find the k7 struggles using afc, it just doesnt seem to snap in to fo...

I had the same problem with my K20 when I bought it!...terrible back focussing.....a friend of mine in the photo trade corrected it for me!..I think the same ,when you buy an expensive camera,it should be "right!"......Ken

As I found with the K-7 it is different from the GX20/K20D. The number one difference (for me) being when you have the dial set to green mode. The K-7 will vary the ISO to 800 automatically with no user input. The GX20 didn't. I was surprised when the shots I took on green with the K-7 were not ...

To the point of sounding "DIM" could someone explain this back focus/front focus and the ways of ajusting to correct the problem. I had a look - but thought don't go there unless you know what you are doing! (Apologies if this is covered in another thread on the forum...:oops:) As stated earlier i...

Do "Other Makes" have similar focus ajustment features? Interestingly yes, they are starting to, Nikon I think in particular. Clearly there is a potential issue, although I have yet to find a lens that needs the focus adjusting. In the days of film there was an issue there as well. When film was ...

Just a thought, but as Jack stated, for the money, the camera should work right out of the box. Just wonder why Pentax included the ajustment feature - unless they know the cameras have the focus probs. Do "Other Makes" have similar focus ajustment features? Yes, they all have it... at least the 'p...

The lens adjust feature is an example of where Pentax gives you extra value - a feature that professionals would expect on their cameras, but which is mostly absent from affordable enthusiast models. It should not be taken to imply that Pentax are aware that their camera bodies are somehow inaccura...

The people who have produced these focus charts give you the impression that they have invented the wheel:shock:. Pentax Service Manuals have always contained a focus chart right back to the *istD :lol: From the Service Manuals it would seem that the 50mm FA f/2.8 Macro lens is used for initial s...
