Well, after 4 months, I finally have a speck on my 400 that will not blow off. Having read that the standard Eclipse solution is not recommended for either the 5D or 400, I though I would pick some of the new E2 solution and as I was running low on Pec pads as well, I started shopping around. Well, I found this great site that has put together sensor cleaning kits for a very reasonable price organized by camera. I know there have been many posts recently about sensor dust so I though I would share. This is especially usefully for anyone who is not quite sure exactly which produce is best for their camera or someone getting ready to clean their sensor for the first time. Anyway, check out:
