Wierd Smudge-Sensor or Lens, FAST

Its in the top/middle/right of the pic. Is it my censor or lens?

Byte size: ZERO | Content warning: NOT AN IMAGE

Looks too sharp to be on the lens. Change lenses, stop down and shoot a blank wall. If it's still there, it's the sensor.

Yep its my sensor. However, I have no cleaning solution. If I cant get iut off with a air can, what shoudl I do?

Either thats the dirtiest sensor I've ever seen, or there are tiny round gray clouds in the sky and refected in the water. Don't use an air can, use a rocket blower, or something like it.

There not. Its the sensor.What kind of household stuff would I be able to use to clean it>?

For a sensor you can either use a bulb blower (ie rocket blower). DO NOT use compressed air and use the sensor clean option and blow in there. This will only move loose particles. OR

use something like a sensor swab and cleaning solution (look up copperhill method)

none.the sensor is too fragile for any household stuff.

I have been lucky. Starting with a D30, then a D60 and now a 30D, all I've had to use was a blower, and not even a rocket blower. And then, not that often.

But don't use canned air, it can shoot droplets out and it's probably too strong.

Man it's not like you're cleaning a table, window, or toilet, it's a sensor.

Anyone with theories how a sensor can get this dirty? Notice that the specks are all over, even around the edges...short of blowing a vacuum cleaner in reverse!

Probably best to bring it in your local camera shop and have them clean it...to be safe.

Use scotch tape it works good.

Tape may leave a residue you'll never get off. If you want to do it right, use a rocket blower or get proper cleaning kits by searchign for the Copeprhill Method". any other way may be too risky, and I would not try them.

Sorry, but that's about the worse advice I've ever heard for cleaning the sensor.

Also, DO NOT used canned air - it may be canned, but it ain't air. It can put a very hard to clean chemical residue on your sensor.

The recommended methods for cleaning a dirty sensor are:

1. Rocket blower
2. Sensor brush method.
3. Copperhill Wet Cleaning method.

A search in the forum or on Google will bring up multiple discussions on the various cleaning methods.

Just because youve never heard of it before doesnt mean it doesnt work or is a dumb idea, thats just being ignorant.
I know many people who use this technique and ive never heard of something bad happening.
