Preventing condensation
Just had a thought about this - shoot me down if I'm wrong please. Gwyn wondered about a filter Oh and I don't normally use a protective filter on my lenses - would one be a good idea given the maritime climate, or will cleaning the lens thoroughly suffice? wouldn't this actually give more pro...

Preventing condensation
Ziplock bag added to my packing list :D: I shan't bother getting a filter, just rely on my cleaning skills. If it is blowing up a storm I doubt very much I'll be out on deck getting wet and frozen :shock: :lol:.

K20 Auto Focus appears to have stopped working
No - never had any trouble with mine. I was just trying to work out where the problem is. If the switch was duff, you probably wouldn't get the AF-S. As it is, the fault is probably with the autofocus system itself. The only thing I can suggest is cleaning the contacts on the lens mount on your c...

K-X Bulb problem
When you take a long exposure (say 5 minutes for example) when the shutter closes the camera will take a second exposure of the same duration (5 minutes again) with the shutter closed - this is to allow it to work out how much of the image is sensor generated noise and is called "Dark Frame Subtract...

Kr IQ
I am finding that there is some inconsistency in the shots that I am getting from the KR, I have found that I am getting much better (sharper results) using a tripod than hand held. As I said in a previous post this camera has to be "worked" IMO, compared to my K200D,perhaps it is the nature of the...

I think the output from CMOS sensors tends to look softer than that from CCD sensors "straight from the camera" so I'm not surprised it doesn't compare that well to the K10 and K100. As JR says, you'll just have to start using a bit more software sharpening to bring the detail out. Unfortunately...

Just a thought I did have a Samsung gx 20 for a year or so and I think it has a cmos sensor but I did not notice any softness in the j pegs from that camera. Ian If I remember rightly (and I'm happy to stand corrected) from the reviews at the time, Samsung used a higher default sharpening level in ...

Kx Menu button won't work :(
I've got a Kx, had it for maybe 5 months with no problems, however it's been off for a week or so and now I'm having some trouble with it... It turns on, goes through it's usual boot procedures (shakes sensor and checks focus) then, nothing. It doesn't matter which buttons I press, I get no resp...

is this sensor stain?
Hi all Just uploaded the image below onto my gallery taken with the 55-300 and 1.4 convertor,but then i noticed marks which i first thought were dust bunnies on the middle lhs (and only f5.6) but am afraid they resemble those sensor stains..what do fellow members think

You won't see the stains at f5.6. You will need to be shooting at at least f11 or more. To test for it set for a 1 sec exposure at f16 and point the camera at a white wall ... the stain should be obvious if it's there. I'd guess that is dust you see on yours - blow your sensor ! Really nice shot...

I've seen dust at F4 :shock:. Do a proper test on it. Clean the sensor, then do as Frogfish says.

o.k cleaned sensor with my arctic visible dust sensor cleaner still marks and look even more like sensor staining to me:( have also just done a dust alert test via the camera where it shows a white screen so you can see dust specks and there aren't any so does this mean it is definitely sen...

Looks too big to be sensor stains IMHO. I'm not surprised to see it at f5.6. I regularly notice dust at f2.8, more so with WA lenses though. It looks like dust to me.

Looks like it to me .. whats the serial number? i am afraid it starts with a 39 and had the 0 on the box bought from srs i will purchase a wet sensor cleaner and try that before contacting chris though as i used my arctic buttery to clean it (usually works)
