K10D focus

So, is that a digital tweak (hack the firmware) or a mechanical tweak (adjust the focussing mirror)? Whichever, does it void the warranty? Mechanical tweaks are a seriously bad idea. AFAIK there is a complex AF table that has to be initialised on a special test-bed. Trip back to Japan for that I ...

K10D focus

Ken, My K10D focus was off. All my lenses backfocussed. Everything was only really in focus if I used a small aperture. The tweak was to bring the camera's AF system more into line with reality ;) As I said, it was more noticeable with the 50mm at f/1.4 (and for a long time I thought it was me ...

K10D focus

So are you saying you reverted back too firmware 1.10 or just hacked 1.30? From what I've read on the Internet, you need version 1.10. And I've also read that the K10D needs a little encouragement to get version 1.10 in there. Should i be asking this here? I'm merely relating what I've read elsew...

Shadow on close image

Received my pentax 50mm 1.7 A lens today and have noticed a shadow on some pics in the top left corner.Wondered if this was due to my closeness with the subject since the pic from slightly further back was ok. [/list]

K100D banding problem

Hello everyone, I've been reading this board for a while now and very helpful it's been too, so I decided to take the plunge and register. Now then, I have a problem with my K100D which, despite extensive searching, I can't seem to see any answer to. Occasionally I get "banding" on my i...

K100D banding problem

Thanks for the speedy reply Matt. I have to be honest here and admit I've not used RAW mode at all and I use Photoshop CS2 to process the pics and yes, the problem occurs at all ISO ratings. The most frustrating thing is, when I took the camera back to the shop today, the assistant took about 2...

K100D banding problem

Thanks again ammonyte. I've used a different SD card and then formatted both within the camera. I've not tried the different PC yet, so that's my next stop. The strangest thing was, that the assistant in the shop yesterday, took about 30 random pics and when I got back and transferred them to PC, n...

K100D banding problem

Once again, thanks for the reply ammonyte. The lines in other pics stay pretty central but sometimes there are less lines. I've sent the camera back to Pentax now, so let's see what they say :) Thanks again, for all your responses.

K100D banding problem

just an update. I sent the camera back to pentax and they have just returned it after carrying out a repair. However, the problem still exists :( I'm going to inquire about getting my money back. I'm afraid I'm a bit disillusioned with them now.

K100D banding problem

You're saying the USB computer connection on your camera is broken - and you don't know if it was broken before it went away? Or are you saying it doesn't work with your computer which is different. How old is your computer and does it fully support USB? Why on earth would you use a reader to get ...

K100D banding problem

Just winding back to my question to John - of course you're right that a reader is vastly more convenient for multiple cards, I never take that many photographs in one hit so that hadn't occurred to me. My thoughts on drivers go back to the oiriginal question - if for example he's using NT or win...

K100D banding problem

Well, thanks for all your helpful replies folks. I did speak to Pentax and like mikew said, they just suggested sending it back. I'm sure my PC is up to the job, I'm running win xp pro with 4 USB2 connections. Johnriley, I'm going to try your suggestion of swapping card readers before sending it ...

Tried a hish-speed usb 2 card reader, with the same results. I've sent the camera back to pentax now, let's see what they come up with. Once again, thanks for all your suggestions and help

K100D banding problem

sorry to but into the thread... I would be interested to know what the outcome was to this problem. I have just got my K100D back from Pentax, as the USB port was broken (it pushed into the camera body when I went to download pics... although under warranty Pentax said there was evidence of impact,...

K100D banding problem

Ok so I sent the camera back to Pentax, and YEY they were speedy in repairing, and only had the camera for 6 days. But BOOOOOO they haven't actually solved the problem :x It says that there has been a standard PCB repair, but I have taken a few quick snaps this morning and although a couple of ...

51mm Filters

I have a very nice Cosinon 135mm manual focus lens which is I use for macro when used with extension tubes. It has 51mm thread size and I cannot get a protective filter anywhere in this size. I have also looked for a step up ring but no luck there either! Does anyone know if this odd size is still ...

51mm Filters

Are you absolutely sure it is 51mm? This tends to be a push-on size for lens caps. It is almost unheard of for a manual focus 135mm lens to be anything other than a 49mm or 52mm fuilter thread. 51mm is sometimes the outside diameter and the inside filter thread would be 49mm.

51mm Filters

Cheap soft focus filter. :lol: :lol: My only other thought is that it might be a Series thread, probably Series VII. Kim 49mm is too small and 52mm too big! I could try clingfilm????????

K10D Spot on some images. Help Please.

Help Please. I shot around 100 images today and during processing noticed a pretty large spot almost in the center of some images. Was shooting for our Fire Dep't in temp of around 28-30F for about 2 hours using various apertures, which I know can affect how much a dust spot shows up, or maybe n...
