K20D AF and Zoom
Ahhhh....OK. I did a lot of SLR work in film, but all my stuff was totally manual. However I just tried my old Tokina 50-250 on my old film camera, and it definitely needs re-focusing. Is it later (D?)SLR stuff that is as you say? Sorry. Not just arguing. Technology moves so fast....I went from S...

K20D AF and Zoom
A word of caution here. Just like some lenses are more apochromatic than others, even if labelled Apo, then some zooms are more true zooms than others. In other words, many "zooms" do in fact wander slightly in their focus when they are zoomed. It's not a perfect world.

K20D AF and Zoom
There are two separate issues here. One is whether refocusing is required after zooming. It is in some cases, not in others in practice. The other question is whether the AF works while you are zooming. The answer to that is yes, but zooming doesn't make AF-S refocus once it has already focused. ...

K20D AF and Zoom
I mean the AF works whilst zooming if you happen to manually activate AF at the same as turning the zoom ring. This is true for AF-S as well as AF-C. Note. Power Zoom lenses (which you are unlikely to use because there aren't many of them, and none are particularly good) are excepted from some of...

K20D AF and Zoom
OK. Thanks Pete. I took most of the above as read (same as my camera). The explanation of the first question is clear now. As I said, I assume that my camera at present "presses" the shutter to maintain focus. Interestingly, the reason I do not use AF-C on the one I have now is that it is genuine...

RAW+
When I look on the camera screen at the photo I have taken do I see the RAW image or the JPG image?? You see a highly compressed JPEG that is stored inside the RAW file along with the proper RAW data. If you zoom in a lot, it looks worse than an ordinary JPEG (you'll see compression artifacts), but ...

RAW+
I've just downloaded a 60 day demo of Nikon CaptureNX2 . It's supposed to be separate from Nikon cameras and I already have Nikon scanner software on my computer. Very impressive piece of software, but sadly it won't read DNG... so much for a universal negative format. It can still do a hell of a l...

White Balance Lens Cap
LOL @ Shim. I've badgered Pentax to change the "RAW" button to work like the *ist-D, but they haven't done anything :roll:. I NEVER use the Raw button. The *ist-D you could just hold down the button (where the RAW button is) and press the shutter release to get a manual WB. It was blindingly sim...

Pentax K20D cheaper, USA only?
Well yes but it's quite new this news 26 febuary but I've no idea how the system works. If the advice price goes down does that also mean that the camera is sold cheaper to the shops if so we should see that back in a lowering of the price right??? But like I said, I've no idea how the system work...

Pentax K20D cheaper, USA only?
people purchase what they think is the BEST and not always the BEST for them. this because I remember going into a camera store to look at glass and everyone first camera they wanted to see was either the CANON or the NIKON but once upon it was NIKON and the sales lady at Henry's in Ancaster said h...

Pentax K20D cheaper, USA only?
Well they got in quick but not with a good design (the 35-70mm on the ME-F). Not sure what happened after that. The P-series was a bit tacky, the SF and Z series were pug ugly, the MZ series seem back on track to me and get the best comments of the AF models. I am sure some of our more knowledge...

Poor Image Quality with My K20D
I can hear the groans just from the title.:D Don't get me wrong, I'm not slating the K20D as I know a majority of owners are more than happy with theirs. I just want to be one them. I've had my K20D for 3 months now, having previously owned an istDL2, and have taken just over 600 photos. And o...

Poor Image Quality with My K20D
Have you checked the focus with a focus chart:shock: Yes sort of. One of the first thins I did when I got it back from Pentax was put a ruler on the floor and took several shots at about 45 degrees from as close as I could get and it just about spot on.A bit heath robinson but... And I can not se...

Poor Image Quality with My K20D
Thanks for the suggestions so far. If it comes back as nothing wrong I shell give them a try. I can't see you last photo, but what were you focussed on for the first photo? Not sure why some can't see the last image, it appears everytime I refresh the page.Maybe your just lucky, its kind of scary...

Poor Image Quality with My K20D
Everyone is talking about the focus but are you sure that is it, what if you try manually focus and without the shake reduction?

Poor Image Quality with My K20D
It may well be something other than focus, but I reckon AF is the thing to check first, especially as Pothers has experience of getting sharp shots on another camera (and with the same lens). Adjustment was needed with my two K20Ds. I can believe that many other K20Ds also need adjustment. Fortun...

Poor Image Quality with My K20D
AF might very well be the problem, I was only thinking of taken it step by step. If you turn the SR off and manual focus the only thing that can cause the softness then is the sensor and/or the processing of the image. If the image is sharp you can turn on AF or SR and see what then happends. I...

Poor Image Quality with My K20D
Got my K20D back from Pentax service last week and they have replace the main board assembly and adjusted the focus, and the image quality is no better than before I sent it of. I was absolutely gutted. I called Pentax and got to speak to the technican who worked on my camera to see what they had...
