K7 auto setting/green mode
Your best bet is get the hell away from green mode altogether and start to use the camera. I am a K-7 user and can assure you that you will get much better results by not using green the K-7 almost always over exposes simply because it will always try to use the widest aperture it can thereby lettin...

Focus Areas with K5/ 150-500
Some advice, please. I use "spot" focus area for photographing birds. This afternoon I was out taking snaps of a pied wagtail. The closer ones are quite a lot sharper than others, the focus point having missed the target. Could it be the case, do you think, that for quite a small target, it's ...

Specks in viewfinder
In recent weeks I've been getting an increasing number of small specks/blobs in the K-5 viewfinder, possiblying because I've been changing lenses quite a lot. Fortunately the sensor is still clean. Are the specks likely to be on the mirror or the focusing screen? How should I set about cleaning...

Specks in viewfinder
An arctic butterfly is unlikely to help you. If it is the mirror these are very easy to clean with a sensor swab and cleaning fluid - you just need to be careful and do not apply pressure otherwise you may move it out of alignment. It is entirely possible that the dust is behind the focus scre...

Specks in viewfinder
Can the specks on the mirror/focus screen affect the operation of the autofocus? What horrible devices DSLRs with exchangeable lenses are! Would a glass window to protect and seal the internals affect the optical performance that much? After all, a lot of people attach a bit of extra glass to p...

Specks in viewfinder
When using a Rocket Blower (or similar) I always give several hard blasts first into the air to dislodge any internal dust ;) When I'm sure it's clean, then I use it on the camera. (And have often used fairly gentle blows onto the focus screen to dislodge annoying dust particles) Matt

Canon Pixma ix6550 printer magenta cast
Thanks for your help - I have just returned the printer back to the shop and am now looking for another. Can anybody recommend a decent A3 printer for between £200 - 300 which wont cause colour cast problems with B&W prints?

Canon Pixma ix6550 printer magenta cast
I thought about what I actually do (in some cases almost on autopilot). Open the .jpg image (PSE10), go to Enhance > adjust lighting > shadows and highlights. This atomatically lightens most any image. Save as a .psd file (non-lossy), then open it again and repeat. Now it is a lot lighter. Go...

Charger Accident
Off post: Lost a mobile phone in October and thought it had been stolen. My wife found it in the garden after Xmas - very wet with a lot of evidence of water having got inside and behind the screen. Left it on a radiator for a couple of days, and it seemed to have dried out a bit but there was s...

Manual focus with 2 Pentax cameras
Hi all, a conundrum. Firstly I have been taking photographs since the 60's so I have learnt a little bit. I own a Pentax K100D also a K5, with a wide variety of lens both manual and AF. On the K100D I have used for many years with good success a SMC PK Manual 300mm f.4, it works very well. On the K5...

Manual focus with 2 Pentax cameras
Puzzling. A manual focus lens will look sharp in the viewfinder when it is correctly focused, so why would it be in focus on one body and not on the other? I think I'd start with ther dioptre correction on the viewfinder eyepiece. Point the camera at a plain out of focus wall and sdjust until the...

Manual focus with 2 Pentax cameras
I'd also double check the SR settings too... Probably try with 2s timer or mirror lockup on a tripod (which disables SR). You could also try using the Live View on the K5 to see whether you can achieve a better focus - since the LCD is a view off the sensor it represents the image captured (whic...

Manual focus with 2 Pentax cameras
Hi again, update on my focusing question. A very senior moment may have occured, I have been focusing through a conservatory window (DOUBLE GLAZED) would this have upset the K5 focus? Expecting replies along the lines of "of course it would you idiot" !

Manual focus with 2 Pentax cameras
If you had been using AF I could see the camera picking up on the glass surface but if you used MF I assume your eye would tell you when the target is in focus. Unless it's some sort of diffraction happening through the double glazing. Or were you using the Green hex for focus confirmation and would...

Manual focus with 2 Pentax cameras
Thanks for further ideas, I agree in that I think it is diffraction causing the problem. The camera was mounted on tripod, in focus according to my eye and the green hexagon, mirror up using remote. When weather/light conditions improve I will do an outdoor set-up and see what the results are. Don't...

Have a look here, this explains how to remove/install the focusing screen. Maybe from these pictures you can figure it out?
