How easy is it to remove fungus?
Does anyone know if fungus grows on the metal insides as well as on the glass? Just trying to get my head around which bits may need cleaning. I like a challenge, and may give this a go. I have access to hydrogen peroxide where I work, so that is helpful

How easy is it to remove fungus?
Fungus can grow anywhere inside the lens. What you should not do is keep an affected lens with any others. Fungus propagates using microscopic spores and when conditions are right, they flourish and can easily spread to other equipment. When they grow on the glass, their excretions can corrode the c...

How easy is it to remove fungus?
If you don't know what you are doing, I'd leave well alone. I have to say that I fundamentally disagree with this statement - sorry! Nobody knows what they're doing the first time they try something - we all make mistakes and we learn from them, for many (like me) that's actually the fun part! ...

So Confused by Various Cameras...
The K-m is aimed at the beginner to Single lens Reflex (SLR) photography, perhaps moving up from a bridge camera (where the wide zoom lens cannot be interchanged) to the Digital SLR with its interchangeable lenses. It is compact and its operation is simple. The K200D is a very fine camera indeed ...

K100D Super Problem
Hi and welcome to the forum. Firstly, the obvious question, has the camera been set to auto focus and not inadvertently been bumped into manual :?: There is also a setting in the custom settings to disable the AF function when you half press the shutter button, have you made any settings chan...

K100D Super Problem
Having read this, I'll ammend my suggestion to that you replace this with the K200D if you need to, and the camera will be almost identical, but with better resolution. The dust spots are on the CCD, so you need to activate the menu item Sensor Cleaning, which opens the shutter so you can see the...

Something to Try (Only for the Brave)
Hi All, I think I've discovered a sure-fire way to see all the crud on your sensor. Not for the faint of heart - like moi - I'm still depressed.. Wait for a blue sky - or use a well-lit, clean sheet of blue paper. Set your lens for its absolute minimum aperture, completely de-focus and s...

Why do the little beggars show up most at minimum aperture? The dirt is actually on the glass cover of the sensor, so a little in front of the sensor itself. Wider apertures mean the light can 'go around' the dirt, a small aperture means the light is coming from more of a point source, so the dirt ...

Gotcha Dan! Great explanation, and I didn't realize there was a glass cover on the sensor either. Good to know. See, this is something us old film dawgs ain't used to. We used to get 36 brand new, clean sensors per roll:lol: Looks like I'll be tracking down an Artic Butterfly as the nex...

Still kinda chicken to use the wet swabs. Don't be, sensors are tougher than we're led to believe I reckon. See my comment on . As I say there, not something I'd recommend doing, but it did at least prove that the sensor is not some fragile, delicate thing never to be touched. The arctic but...

If I can put my 3p into the 'discovering sensor dust' fun ;). I have possibly better way, manual focus (and whatever focus setting), take a picture of a white/gray (best - uniform) wall, or piece of white paper, you can boots exposure a bit to get that white/gray object more white than gray ;). Loa...

Wait for a blue sky - or use a well-lit, clean sheet of blue paper. Set your lens for its absolute minimum aperture, completely de-focus and shoot the sky. A couple of years ago, on the morning of the southerners PU meet in St. Albans, I used this technique to make sure my *istD sensor was spotle...

You know, the K200D also has the built-in dust detection. So no reason to limit a competition to the K20D :D Btw, I have used the Sensor Swab on my K100D with good results. Just make sure you get the right fluid, there are two types. And I believe that cameras up to K100D inclusive use the Eclips...

A better way to see the crud Mac, is to open PS or similar, open a new canvas make it full screen. Set the camera in Av mode and dial in the smallest aperture, it will give a shutter speed of several seconds, no problem the crud is stuck to the sensor and doesn't move, in fact I move my camera delib...

My sensor was filthy at one time (had many comments here as it shows up badly when doing macro shots) so I invested in a product called . It was pretty expensive :shock: but I used it just the once and havent noticed any comments since.

If a blow with a rocket blower doesn't fix it I use Photographic Solutions sensor swabs and Eclipse E2 fluid. Had no problems at all though its a little scary the first time you do it. I must have cleaned my *istDS close to 50 times, I don't get anything like as big a problem with my K10D. They'r...

Checked my K200d sensor with the built in software, ARGH!!!:cry: quick shake , using the built in software. Phew! all the dust has gone. now on the K110d it's a case of using one of those lens pen things to brush the dust off. :lol: Cleaning's a lot easier with the up to date models :D
