My Copperhill Experience

So I got bored with my gear somewhat, and just felt like purchasing the next item on my long list of photographic "to-buys".

Next up was a cleaning system for my 40D.

I took faith in what I've read, that the antialiasing filter in front of the sensor is quite sturdy (I'm of the opinion that lenses also don't need filters, because optical glass is fairly strong). I decided to test out the Copperhill Imaging system of wet sensor cleaning, partially because it is well known and highly regarded. And reasonably priced to boot.

Well, ordering was straight forward. It was nice to know they accept an international billing address and different shipping.

It took a while to arrive, but I didn't mind. It got here today. I looked over the bits and pieces and reviewed what I needed to do.

I prepared myself placing all the bits nearby. I inspected the parts to get a feel for what they were. I took, hopefully, one last shot on my most critical lens, the ef-s 60mm Macro at f/32 after my usual procedure of two in-built sensor cleans followed by a rocket blow. You can bet that at f/32, you will see EVERYTHING.

Then, much like Indiana Jones preparing himself to snatch the fertility idol in Raiders, I set myself to go...

I swabbed once forward and then once back. Took a shot at f/32 - it had cleaned some up. I took a new pad (I was a bit too novice to chance myself at cutting it up into quarters for now), wrapped it up, and repeated the clean. Two more goes later (after developing my folding technique to something I'm more comfortable with, as well as using only one side of the pad, with one swipe), I decided to stop.

I don;t think my sensor has ever been cleaner. It managed to remove spots that have been there since I bought my camera, but only showed up at f/16. Now those are gone all the way to f/32, with only one dark spot (and faint), and one what looks like a wet spot. But I think I will leave those for when I next do a clean.

So long as I haven't damaged my sensor coatings, I feel it has been a very positive experience. I guess my pictures in the next few days will tell, but I am very happy with the results so far.

I would say the best part is using the 'once' used pads to give the external body of my camera a clean. I now have a very shiny LCD, viewfinder, and iPhone.

Yeah, I know, this was a boring story.

So what's the deal with the rainbow slinky? Just a corporate logo 'fun' gift? It seems like it;s all glued together ... I guess, I can pull it apart...

Thanks for taking the time to write up. I need to get on the ball to clean my 5D

Yeah, when I first attempted the sensor cleaning, I swear my heart was choked up right around my throat. I was so nervous, fearing that 1 slip, there goes $1000 (for me). I don't think I'll ever get to the point where this becomes just routine and 2nd nature. I'll always be afraid. :D

I figured out what the slinky was for:
