Got the green line problem on your K-7?
My K7 has the green line and firmware v1.11 I've updated to v1.12 and haven't had the green line come back. But as the summer temps will be up in the high 30s-low 40s deg C, if it is temperature related, it should become obvious pretty quickly. I tried leaving the camera out in the sun to warm up ...

Got the green line problem on your K-7?
I was wrong. It's still there. I took some moon pics tonight and it's quite clear against the black sky. It's 20 deg C so it doesn't seem temperature related. It's off to the importer for repair I suspect. I never got back to tell you what happened. I sent it off to Pentax Australia and they di...

Returning to the Scene
Hi everybody, been browsing the forum and now decided to join you guys. Just turned 64 and coming up to retiring next July and have decided to get back in to photography. Previously owned a Contax 139, Zeiss 50mm 1.7, Tamron 70-210mm and Sunagor 15-35mm ( I think). Sold them due to cost of film p...

Returning to the Scene
Welcome to the forum. My brother-in-law bought a 50D to compliment his 20D. He had it a couple of days and sent it back for a full refund because the image quality was not as good as his 20D. He now has a 40D and is very pleased with it. K20D is my choice. I'd probably like the few improvements o...

O-ME53 Magnifying Eyecup
I've just changed from a K100D to a K20D. I'm finding I'm having to look twice through the view finder for each picture - once to compose and focus and then again to check the viewfinder symbols down the bottom. I don't seem to be able to see the whole lot in one 'eyefull'. I don't recall having ...

O-ME53 Magnifying Eyecup
Malcolm, I have the K20D and am pretty shortsighted (obviously wear specs!). When I use the O-ME53 I find I can see the whole viewfinder by moving my eye fractionally higher - so it's a physical movement of the camera or head. Generally it's not too much bother, but I've recently gone back to no...

K20D Help
I've just about got my K20D set up to my likeing but i've a couple of questions. When pixel mapping is activated is it on permanently. what is catch in focus. Thanks

K20D Help
When pixel mapping the camera identifies and compensates for faulty pixels, so once you've mapped I presume the camera knows from then onwards not to see those pixels but to fill in the blanks by some form of sampling from neighbouring ones. Catch in focus works when a manual focus lens is on the...

K20D Help
I tried catch in focus at Goodwood. I was standing at a corner of the track and focused at a point on the corner then waited for the cars to come. Results not great. Possibly better with slower subjects.

K20D Help
An interesting question Richard, perhaps it could in the engineering menus, but why would we want to reveal faulty pixels? I know it's not quite the same but it would be a bit like having a faulty shutter repaired and then asking if the fault could be put back. Are you concerned that by pixel map...

K20D Help
It took over 4 months and over 2500 shots before I spotted a dead pixel on my K20D and I then went back and checked the first shots taken with the camera and found it there too. Once I had seen the dead pixel it got really annoying. I could see it on most of my shots. However pixel mapping sorted it...

K20D Help
I agree with George I think there has to be a balance made between absolute perfection and cost. Don't do this unless you are prepared to be disappointed but I have found the best way to check for hot pixels is to turn off slow speed shutter noise reduction (custom 17 on the K20D or 18 on the K-7...

K20D Help
Thinking about it slow shutter noise reduction probably makes no difference to this test. SSNR is looking for low level noise differences between the actual shot and a shutter closed shot. A hot pixel, having such a large change in brightness, probably will not be classed as noise and not be removed...

Who has, will have a K-7?
Was next to "Greytop" when I picked mine up at SRS. Love it. No regrets and would find it difficult to move back. K-7 is perfect size and handling for what I want. But the single biggest issue that would make it hard to go back to earlier bodies for me is low light focussing - it nails this quic...

Who has, will have a K-7?
I am actually quite tempted by the new Canon 7D, if the 18mp sensor is any good at high ISO I can see my self having a good hard look .. mainly for the MP-e 65 macro lens as no one else does anything remotely like it. If that were to happen (a big IF) then I would still keep my K10D and Sigma len...

Who has, will have a K-7?
I purchsed mine back in July and for my main type of photography which is aviation it was a step up from the K20 (the other half uses one now) but not quite the leap I thought it would be in terms of FPS. Having said that it is quicker than the K20 and I have got some images which I might not have ...

Who has, will have a K-7?
But at the moment it is back at Pentax UK courtesy of SRS with a damaged sensor. I used it for a week in August with no problems and a couple of weeks ago noticed some "dust spots" on my images at the same place with different lenses. I took it back to SRS and they confirmed it was damaged so they...

Who has, will have a K-7?
The shutter is closed and the sensor covered when changing lenses, so damage at that point does seem rather unlikely. Just to go back to this, I was using a 17-70 for my first image of the day with no problems. I changed the lens in a dust free enviroment to the 60-250mm and from the second image t...
