QUESTION FOR THE CAMERA XXXPERTZ:

I recently purchased a used DSLR (12,000 actuations) for $200 below retail off some dude on Craigslist.
When taking some test shots with it this weekend I noticed OMG SHIT ON THE SENSOR. Bought a can of compressed air, blew out the interior, and got rid of most of it except for 1 fucking dot that won't go away.

Wat should I do?

1) Return the camera to the dude and tell him he is a faggot for not keeping his camera clean.

2) Buy some Sensor Swabs ($45) and try to clean it myself.

3) Take it to a pro shop and get the sensor cleaned ($???).

4) Fucking learn to live with it it isn't that bad OP you dumb vagina.

Oh yeah also here is original example of what kind of shit was on the CCD before blew out the interior of the camera and used the dust removal feature several times.

>a can of compressed air

You're lucky it still works ok. Don't do it again, compressed air causes moisture, and moisture kills your camera.

>Fucking learn to live with it
This. The dot should be progressively less visible at larger apertures.

When you get more dots you can't get off with a blower, this.

lol. Should've tell the dude he's a faggot before you spent time cleaning this mess.

Also, Pentax dust removal system is about 99.8% useless.

I is using special gay No-Moisture Memorex™ canned air that is meant for electronics applications. But fair enough point and thanks for the advice. I suppose even with the $50 Sensor Swabs it's still $150 less than retail, it just takes me from getting a fair deal to getting kind of a shitty deal.

To be clear, that's an out of focus photo of a textured wall. The circled shit (as well as some of the other black pinpoints) were the persistent marks. The overall EW GROSS SHIT EVERYWHERE is actually just the background object.

Get a home sensor cleaning kit with scope and vacuum.

Got any suggestions on brands, etc?
I've mostly been leaning on a photo major friend who worked at Ritz for several years (and hated it) and he keeps suggesting the Sensor Swabs™ (http://www.photosol.com/products.htm) or the pro cleaning.

I have used the Delkin system without problems: http://www.delkin.com/products/sensorscope/

Can't really compare it with the others though.

$149?!? Pro cleaning would cost less.

Apparently you don't understand the concept of buying used shit. Stuff may be wrong with it, and you can't take it back. That's WHY it's cheaper. If you were guaranteed everything would be fine, why should the seller expect anything less than full retail?

2. If you quit taking pictures of solid colored walls, you probably wouldn't even be able to see it. Use your fucking camera instead of obsessing over it's flaws.

I can use it whenever I want, even for small spots and it takes no time to do it.

Sending it off for pro cleaning is more expensive, means I don't have my camera and requires leaving someone else or even the post office to handle my camera.

If I walk into a shop that does offer the service for sensor cleaning on a same or next day service that will be £50 ($100).

Don't be so cheap.

Because, uh, it's used? 13,000+ actuations = 13% of the camera's life. That alone warrants a discount. Beyond that the dude lied about the camera's use (claimed 2,000 actuations) and said it was in minty condition.

Part of what this camera is for is light-box photography of products for print in magazines. Gay dirt on the sensor that's going to show up is an issue, because it means I have to waste time cleaning it up in Photoshop.

Buyer beware, welcome to the world. Also whenever you buy a used camera you should expect to have to do some kind of service on it. Stuff gets dirty and breaks down whether you use it or it sits on a shelf.

If you're doing professional work and are going to get your panties in a twist over a piece of dirt on the sensor, buy a new camera with a warranty and expect to clean it or get it serviced regularly.

Compressed air for electronics.
I know how to use it, I didn't tilt it all faggy, I fired the first few shots away from the camera, etc etc.
Compressed air has come a long way from the days where it used to shoot freezing liquid on everything.

>If you're doing professional work

Semi-pro at best. The photos I generally take are used in trade publications, etc.

Fair enough, but I have a lot of options for pro cleaning in my area and I've been quoted about $50.

Seriously? My local camera shop offers a free sensor cleaning service, even if they know you didn't buy your camera from them. They do a damn good job too.

gb2/physics/. A can of compressed air DOES NOT "shoot liquid". The problem is that the blowing air gets cold due to rapid decompression, cools down the target surface, which then can become moist because of condensation if it comes in contact with hotter air.

The biggest reason to not use compressed air is the great force in which it slams delicate components. Like your mirror

you have to be extremely retarded to blow air in a way that will break your mirror

WAIT, haha. You bought a used camera expecting it to not have problems? And to top it off you bought it on craigslist?

Then you blew compressed air into it? LOL

gb2/physics/ air, when compressed enough, becomes a liquid. Canned compressed "air" is usually not actually air, but usually propane or isobutane stored in liquid form. If you don't believe me, try spraying while the the can is upside down. The gas at the top forces the liquid in the bottom of the can out through the nozzle and liquid will spray out.

Which is why you always have to hold the can at a 90º angle, always do a test blast away from anything before using it on any electronics, and never ever ever continue using the can when it's near empty.

You have absolutely no idea what you're talking about.

When used properly there won't be any fucking liquid coming out.

>2) Buy some Sensor Swabs ($45) and try to clean it myself.

you'd have to buy them eventually anyway because this shit just happens no matter how careful you are. at least you saved $200 buying it used so you can afford a nice cleaning kit.
