Dust is rapidly becoming the bane of my existence.
It's now managed to find itself onto the focusing screen and is being a stubborn little bar steward. -although, it doesn't appear on my photos.
I was thinking though, in between swearing and other such things - Does dust really effect lenses etc? I'm assuming it's not a massive issue until you get dust onto your sensor.
Other than that it's more an aesthetic kind of thing.

Get a Rocket Blower if you've not already got one. I'm fairly OCD about dust on my lenses, screen and sensor. The blower gets rid of most stuff. As for the sensor, you can check how clean it is by taking a shot of a white piece of paper or similar at f11. Visible Dust make good sensor cleaning kit.
Dust on a DSLR focus screen is annoying but not an issue for images - unless the dust drops onto the sensor during use.
Assuming you can remove the focus screen (as you can easily with anything that will take interchangeable focus screens) you can simply remove the screen and clean it with a bower and/or some appropriate fluid. Make sure you don't let more dust into the prism housing area when you do it!
Visible Dust Arctic Butterfly gets my vote for sensor cleaning - different brush sizes for different sensor sizes. For anything rather stubborn (or oil spots for example) a fluid base cleaning solution of some sort may be necessary.

Dust is a bloody nightmare. Blowers are ok, but don't sort the problem. I send mine off every year to get the sensor cleaned. It's not that noticeable unless you're wide open. This morning's shot was a real pain as it was f20 (or some such).
This is a 1:1 (pre pp) from the shot below:
and yes, it's due a clean (waiting for the D800 to arrive so I can send it off). It's always the same corner of my sensor that really attracts it for some reason (bottom left in portrait!)

I already have 2 Rocket Blowers and they get used to death, I think that for some reason my gear has just begun to attract dust from somewhere... Most of it is external, on the mirror or on lenses at the moment.LongQ said:

I've removed the focus screen and given it a good blow - the dust still remains though, and tiny hairs - It's twisting my melon something chronic having it visible in my viewfinder though.Assuming you can remove the focus screen (as you can easily with anything that will take interchangeable focus screens) you can simply remove the screen and clean it with a bower and/or some appropriate fluid.

That pre pp shot looks quite painful Steve! I'm glad mine's nothing like that, I think I might have to purchase a new focus screen (I'd like one for 2.8 and faster anyhow) and send it in for a clean at the same time.This is a 1:1 (pre pp) from the shot below:

It can be very tricky to get certain focus screens entirely free of dust. I tend not to bother with it too much and after a while don't really notice.
Buts that's for action stuff. The dust is much more annoying for other subjects where the dusts and spot are more intrusive to the composing aspect of the work.
