There is a spot showing up in my pictures. I've changes lenses and it's not that, so it must be the body.
A local shop charges $75 to clean the sensors, etc.
Is this reasonable?

I'm in CT if anyone knows of any other shops.

Thanks

It depends. Most learn to do it themselves. A cleaning kit can cost as little as $30 and it will last you pretty much the rest of your life depending on how often you clean. :) Ok, that's an exaggeration, but I still do have my first cleaning kit purchased way back in maybe 2006 and it has cleaned sensors from and 300D, XT, XTi, 40D, 50D, 5Dc, 5DII, and 7D with a few others tossed in from time to time for friends and family and I'm only 1/2 through the materials. :):). So I figure my DYI cleaning is going to turn out to be something like 30 cents a cleaning so your $75 is a 250x markup. :)

But if you do not feel comfortable doing it yourself or learning how to do it yourself, then the cost sounds maybe a little high but not unreasonable high.

Wow, I just checked and the cost has gone up. Back when I bought my kit it was $30. Now it's $48

Is it reasonable to charge $75 to do something that most people can easily do themselves in less than 2 minutes? Well, I suppose that all depends on how much you value $75. If you're a billionaire then I suppose $75 is reasonable.

Personally, I'd have laughed in their faces.

i got a rocket air blaster...

what do I do, just take the lens off and use it? I couldn't find any sort of cleaning mode on the camera. Do I turn the camera on/off before I try this?

This is a Rebel T3.

Page 173 of your manual (an amazingly useful thing - especially the index, under Sensor Cleaning).

  • Blast the rocket blower anywhere away from the camera a few times (to remove any crud that may be inside).
  • Remove the lens from the camera.
  • Put the camera into manual cleaning mode as described in the manual.
  • Point the rocket blower into the inside of the camera (the area known as the mirror box) but keep the end of the nozzle outside the mirror box.
  • Give a few sharp blasts with the blower.
  • Switch the camera off.
  • Replace the lens.
  • Take an image of a bright, out-of-focus area (sky, white wall) at f22 and check the image for dark blobs.
  • If needed, repeat.
  • If you still have blobs then you'll need to investigate wet cleaning, or a Lenspen SensorKlean.

THe first time through is the most difficult so plan on spending a little more than two minutes. As with many things the cleaning is quite simple but there are some things you really have to watch. If done sloppy or carelessly, you can do some serious damage.

Tips for the blower:
- Mount the camera on a tripod or at least on a table top. This frees both hands to do the blowing.
- Make sure that your battery has at least 10~15 minutes of charge. I never clean unless the battery is at least 1/2 charged. The last thing you want to happen is that the shutter closes while you are puffing.
- Use one hand to press the bulb and do the blowing and use the other hand to control the tip. Take lots of care so that the tip does not scratch the sensor.
- U bunch of medium blows is safer than a couple really aggressive ones. Te last thing you want to do is poke the sensor with the tip of the blower.
- Don't get frustrated if it doesn't get everything off the first time. Most times several cleaning cycles are needed. THis is true when wet cleaning as well.
- Sometimes things just will not come off using the blower. If that's the case, time to try another method. THere are many to choose from.
- When in doubt, slow down, take a step back and start over. As mentioned, cleaning is straight forward and pretty simple but it is also risky and anytime you are poking a sharp object at your sensor, bad things can happen so again, use lots of caution. Don't let the tip hit the sensor.

Mr. Hollis stated:

You can make this more effective by using a relatively long exposure and moving the (camera) body in a concentric circle (is that redundant?) while the exposure is being made. Since the camera is moving, ANYTHING that shows up in that shot is either on the sensor or the lens. This will tend to cover up variances in paint reflectivity and incidental reflections when shooting a light-colored wall.

I would pay $75 for a sensor cleaning. I know me. I'd ruin the darn thing obsessing about it. Oh, and I'm not a billionaire. If I were, I'd pay someone to take it to the shop for me. What the hell, dirty sensor, buy a new camera!

I use a Visible Dust kit. The kit is a bit pricey but you do a lot of cleanings it is cost effective in the long run.

The first time you clean a sensor you will experience some nervousness but after that everything is fine.
