'Dust Bunnies'
« on: July 04, 2005, 11:36:28 PM »
I know a lot of people are concerned about dust on the CCD's and what they can do about it when the day comes. So, maybe we should have a thread for it. There's a lot of websites around to help with this digital problem, all of them full of disclaimers. So, here's one; What you do to your camera is your fault, so don't blame me or anyone else here if you prod your CCD so hard that you bust it open.


So, what do you do about dust bunnies?

I clean my ccd 's with PEC PADS and Eclipse cleaner, but only when they need it and have had no problems whatsoever. If you know what you're doing it's just routine and, as I said, there's lot's of help out there.

Personally speaking, I found out pretty quickly that blowers just make matters worse, sometimes covering a CCD is twice as much dust as before. Whether it's stuff in the air or rubber dust I'm not sure.

Olympus came up with the ccd-shake which supposedly removes dust. Sounds like a great little invention.

I only had to clean my sensor once in 6 months. If you follow this instructions on changing lenses etc properly then you should have no real problems.

Heh, lucky you  :)  for me it's every month. Not as if I leave my cameras lying open on my desk, you understand.

I find I have to change lenses all too often, usually between macro and tele and wide while out in the field. Personally, I find dust floats both up and down, and turning your camera face down doesn't magically eliminate the problem. I think I notice dust a lot becuase I shoot a lot of blurred backgrounds, upon which dust is obvious. Whereas it's invisible on other details. I usually use F11 too, for macro, and dust shows up a lot more.

Everyone has different experiences of the same problem. Ever had a stuck pixel? I had one that stayed for a few days, then vanished.  :o

Yep, I get dust specs on my sensor from time to time.  but I huff them away.  So, they occur, but not a problem

Compare that to the annoynace of having to carry ISO 100/400/1600 film stock, not being able to go overseas with anythig faster than ISO 400.  Carrrying 2-3 camera bodies .... occasional dust on the sensor is therefore:  not an issue.  In comparison.

That's a good point. :)

I knew we went digital for some reason

Digital body is cheaper than 3x film bodies .... and "no" running costs once you got the cards and cells you want.  And changed a few lenses!!  Actually its a case of ADDING a new wide angle for most people I guess if you are already in Minolta?

Well, I stuck with KM and waited for the 7D because I must have 9  Minolta AF lenses in all. Most of them used or ex-show pieces, though not all. I really do use them, but I've not needed a wideangle lens for the 7D, I don't use that focal length and the 24mm is wide enough for me after the conversion.

I have not had a problem with that yet, but I have only had the 7D a few weeks so far.
To pick up on another point though, namely the lens focal length, I thought when I brought the 7D that this was a unique "problem" (if you call it a problem, I don't) with the KM body.  However reading a mag the other dayit seems that most if not all digital bodies are the same.  Have i got this right???  Can anybody tell me please  :D

You mean focal length conversion? That occurs on all digital bodies unless they're full-frame. Olympus have stuck their neck right out and introduced the 4/3rds system. Maybe not the best idea. Certainly hasn't made their lenses cheaper or even the bodies cheaper, which would've been a  clear benefit!

Most Dslrs suffer from tunnel-vision. I have a D70 too and it's constricting compared to the 7D, which has the best viewfinder I've used short of a full-frame slr. However, it's not that big a deal.

Personally, I think full-frame should win over in the end, simply becuse it's nicer. It'll take a while for it to cheapen off. That's for sure. Guess we'll find out one day.
