While we are talking about dust and cleaning the sensor of the Digital Single Lens Reflex (DSLR) cameras, I wanted to show a slightly different direction, some sort of think-different solution that can be used in some cases.
I intend to leave soon for a safari in South Africa. My Konica-Minolta Dynax/Maxxum 7D will come with long tele lenses (a Minolta APO 200mm/2.8 and a Minolta APO 300mm/4). As I intend to shoot wild animals that will probably be always a little too far, I also bought a 2x converter from Minolta specially adapted to these nice white lenses.
One free side-effect of using permanently a 2x converter on the 200mm lens is that when I will be willing to move to the 300mm (unfortunately, I will loose the AF coupling since I don’t have enough dough to have an APO 300mm/2.8), I will not even expose the sensor to the ambient dust.
Isn’t it nice to use the 2x or 1.4x converter as a kind of anti-dust cap? It works on all brands; With Konica Minolta as well as with digital cameras from Canon or Nikon.
Maybe not if you are shooting landscapes with a wide angle lens, of course… But with buffalos and cheetahs?
