In reviewing different methods for sensor cleaning, there is minimal mention of using suction. Unless the particles are actually embedded into the sensor (does this happen?), this would seem to make sense.
I understand the dangers of using something large like a vacuum cleaner that could dislodge small components.
What would be the risks of using something like a small surgical suction? This would not actually touch the sensor but with an opening of 4-5 mm it could be focused to remove dust on the sensor and ambient dust as well.
For the vast majority of cameras, you're really not dealing with the sensor. It's safely tucked under the low-pass filter, which is what you are going to be cleaning.
I don't know why a Rocket Blower would be any less desirable than a small vac.... both are simply using the movement of air to (hopefully) dislodge the debris. it's just a matter of the direction the air is flowing.
I hate when people ask me what I see myself doing in 5 years...... I don't have 2020 vision!
My repair shop uses something like that to clean lenses and camera bodies, as mirror boxes ! Once the dust is gone he goes for a wet clean. Of course he dwells in a white lab (I've seen it) where everything is spotless, but does recommend the process (green-clean has some portable vacuum apparatus)!
Those of us who live 200 miles from a "metropolitan" center without a Nikon service center just love this kind of "get over it" panacea. Just swabbed some major debris off my filter today. I am guessing that to get Nikon to do that would take about 3-4 weeks, several hundred dollars and the threat of an imminent cessation of corporate liability due to evidence of user tampering with Nikon only service related items. Maybe next time I'll drop it off at the local camera shop. Tom
I finally had the opportunity to use suction on the sensor. Nothing earth shattering but I wanted to post in order to add to the body of knowledge. So here is my experience with suction and compressed air.
Firstly, I inspected the camera with is lighted loop and found a number of dust particles on the side before reaching the sensor/filter. These were easily removed with a small surgical suction.
Next, I used the suction on the actual sensor/filter. To my surprise, the dust spots (there were only a handful) did not lift right off with the suction. I had to come almost into contact with the surface to get some (not all) to lift off.
For the stubborn ones, I then used a couple of small blasts of compressed air. Apparently, that stirred up more dust as the sensor had a few more spots after the air.
Finally, I went back with suction and removed a few more specs of dust. For now, I am done. When the sensor needs cleaning again, I will use the established methods.
For those of you considering suction to remove dust. My experience was nothing special. While I may have removed loose particles before settling on the sensor, there was nothing revolutionary.
