KR Stain
I've found rocket blowers to cause more problems than improvements and now only use it to blow dust from the front/rear of lenses and dusting my slides/negatives off before scanning them. More often than not, the rocket blower moves the dust, usually to an even less accessible place like behind t...

Tempted to try a household vacum cleaner, from a long distance... I wouldn't, as the temptation is to get closer and closer until..... I tried this method to clean the dust and crumbs? out of my keyboard and managed to suck up one of the keys. Not quite a disaster in the same league as sucki...

Where does all that dust go. Does it just build up until the camera is useless. I wouldn't worry too much about it if I were you. A while back I bought a second hand K-m from ebay and although it was in good external nick, on arrival the sensor was covered in dust and debris, as was the focussing s...

LCD screens ...
In the last few months I have noticed that i am finding it a little more difficult to see the green focus icon in the viewfinder, although I am still managing to take a few decent pictures [please see my grey 'squiggel'in my gallery]. The problem has set me thinking about using the LCD screen for...

The K-01 screen has enough resolution to make it useful. After that, the limitation will be our own eyesight. Fortunately, I'm short-sighted, which means that viewing a screen up close is no problem. To view in daylight I simply shield the screen with one hand, so again, no problem. Hoods can be ...

Just as an aside, 'Hoodman' had a stand at Focus (although they weren't actually selling anything!)and they were showing a version of the loupe with a fitting that fixed it via the flash bracket for shooting video - and I have to say I was extremely impressed - an amazing difference!! It's a bit ...

The K-01 only has the rear screen for viewing. So does it not, in effect, have live view and show the information that you would normally be given in an optical view finder e.g. focus confirmation?

All cameras using the rear screens have focus indicators on the screen - usually red squares that turn to green. It's different from Live View also in that there's no need for the mirror to be locked up before it works. It should therefore be considerably quicker to employ.

And the winner is
You don't have to use only £5 Tesco clubcard vouchers either. I used £5 + £5 + £4 + £2.50 to order £30 worth of Jessops tokens. £16.50 total clubcard vouchers became £15 used to buy £30 worth of Jessops tokens and the remaining £1.50 credited back to my clubcard account.

Possible K-5 WR problem
Hallo PU I've had my K-5 for service to repair a damaged Viewfinder LCD and Top LCD. When I got it back, I discovered that the rear wheel, sounded noisier than the front wheel. It is also noisier than the shutter sound. Now I have discovered that when I zoom my 18-135 WR from 135 to 18mm, s...

Possible K-5 WR problem
I would send it back, it certainly doesn't sound right,

Possible K-5 WR problem
+1. If air can be forced out, it can be sucked back in (with dust, water, etc), unless, of course , it's a one-way valve, which leads to the question, anyone know how WR bodies and lenses handle 'pumping'? Any (non fixed) lens will act as a piston, so air is being pumped in and out as the focus o...

Firmware update side effects?
Whilst browsing around found some comments on the Pentax Forum.com website that some are finding that the latest update has improved focus sensitivity. Although it seems unclear if this is purely on the mechanical drive with the later models, however I didn't notice any reference to the SDM drive. ...

Firmware update side effects?
Early morning misty conditions with a distant subject sounds like a lack of contrast; the life blood of the autofocus system! If you've got the focus right manually, just disable the autofocus in these conditions. John

Firmware update side effects?
The containers were red and white, sun was up at 08.30 and I expected it to hold. Really grey mist would be zero contrast which I've had with still water on grey horizon. As with all long lenses once focus slips off target hunting begins, and the longer the more critical. I've chased the kites w...

Eat My Greens! - Colour calibration Jpg/ Raw/ Tif
Right - quite a bit to try there. I'll go through things in stages, but first, I'll try changing back from Argb to Srgb to see if that is a simple fix - though I suspect I've opened a can of worms for myself :wink: Interesting about Silkypix, I had originally used that when I started out a few y...

How to check K-5 for usual defects?
Find a blank wall, set it to F22 and take a shot with the flash up to check your sensor is clean as a whistle. Mine is back in at Johnsons yet again. The lens release button having fallen off, I'd noticed some tiny black specks on the edges and asked them to clean the CCD at the same time. It ret...

Yep, legitimate retailer, got receipt and the warranty slip (+ extended warranty)... Not hell bent on finding anything... But, hell bent on finding anything that IS there... Stuff like sensor stain ain't really a problem in most cases, but it can be if one shoots uniform surfaces (shape and colour ...

K-5 Where to buy
Thanks Barrie. I got in touch earlier on today with SRS. Problem is there based in Watford, no way my lady could get there and back in time. Pity they don't have a place more central really. Regards D
