There has been a lull in Journal assignments and a quick turn-around time for sensor cleaning at my preferred camera retailer, so I started to bring in my second string, then my first string, bodies in for cleaning. In all I had five bodies in my combined first and second tier bodies, but my third tier D70s needed some attention.
I described a relatively simple system for checking your on DSLR's sensor for dust spots in this post. For my D70 and D70s bodies, I decided to check them with my Sensor Scope and found that nearly all had some dust on their sensors. At $50.00 per body, I was looking at a sizable cleaning bill if I were to clean every camera body. Faced with this potentially large expense, I decided to explore cleaning the sensors myself.
On final note: The instructions clearly state that you may need as many as four swabs to get your sensor clean (the swabs are used only once - one left stroke and one right stroke). I would still suggest that you get a Sensor Scope (or a similar product) and use it to check your sensor after each swabbing. And don't forget that a blower like the Giotto Rocket Blower, may be all you need to to blow away the loose dust. The blower, besides having a cool "rocket" shape, has an internal filtration system to prevent it from sucking in airborne particles and blowing them onto your sensor, in important feature. You might just find out that a little "whoosh" from your Rocket is all you need...for now.
