Scratched Image Sensor

Hi, I think I may have scratched my image sensor on my Pentax K30. I cleaned it using a glasses cleaning cloth. Yes, I know I know, stupid. I wish i had looked how to clean it properly. Anyhow I was wondering how much it would cost to replace, if it's even worth it.

I think it all depends where you are at and where you will be sending it... best bet is to call your local Pentax and have a chat with them over the phone as to what is involved and how much it might be...

Thanks. Silly mistake by me though. I'm new to DSLRs as you may have guessed. I'm in the UK in the north east.

Does it show when you take a shot ? May be OK as is.
Just use a blower to remove dust, Sensors almost never need any physical cleaning.

Yeah it does on higher apertures. I was just looking through my photos from today and I don't think the sensor is scratched, I think it is just dust, phew. Going to get myself a cleaning kit, including a blower

Dust removal procedure in order:
  1. Use the camera dust removal system (shaker) There is a menu setting to turn on/off. If you have dust run this several times. I leave mine on "run on startup" and think that is best so you don't have to worry about it.
  2. Use a 'rocket blower' or equivalent to blow off anything the shaker will not get rid of. Do not use compressed air or canned air. Some folks report it is OK to use canned air if you are careful, personally I'm not taking any chances.
  3. Use a wet cleaning kit. This is the last resort, and on two cameras with over 25,000 actuations in all kinds of environments I've never had to use one yet. Get this if all else fails but don't go there unless you are sure you need it.
  4. Send in for professional cleaning. Pentax extended warranty (in the US) includes one 'free' cleaning. Not sure about UK.

Get one of these : Rocket-air
They are readily available at most photographic outlets and definitely one of the best.

Looking at that gallery image, a wet cleaning is in order. You might have to do it several times to get rid of all those smudges.

In the UK, Calumet do a good job, if you aren't up to it yourself.

It looks like some of that sticky thing around the sensor that is supposed to catch dust removed by the dust removal system has been smudged to the glass on the the sensor when you cleaned it. Get it professionally cleaned and don't touch the sensor like that again.

For what it's worth, here's my sensor cleaning method. The link in that post for the brushes is now dead, but the rest of the info is there.

Here's where you can get the brushes now. These do a great job on sensor dust & I swear by 'em. They're also nice & cheap.

The good news is that the sensor is covered by glass, so if you did scratch it, you scratched the glass, not the sensor itself. What impact this might have on cost to repair, though, I have no idea.

I doubt you have scratched it. It really isn't that easy to scratch glass.
