My Mark IV needed cleaning so I took the plunge for $100 and joined CPS Gold. You get 2 free "clean and checks" as part of the membership so that's why I joined. But there's more it turns out....
Nice medium size FedEx box waiting for me today with all sorts of bonus stuff. I got a sweet looking camera strap that says Canon and CPS. I'll use that. Canon lens cleaning cloth. Ill throw that into the pile of microfiber cloths. A "CPS" pin! Not sure what to do with that. Got a new lens dust cap and new camera cover cap. Can't hurt to have extras. Got this hard cover book called "EF Lens Work III - The Eyes of EOS". This is actually a sweet book. I'm digging that. 271 pages coffee table book all about EOS lenses, photos, technical stuff. Nice. Got an EOS catalog and then of course my membership card, clean & check coupons, Gold Rush Repair pre-printed shipping labels and more....
I'm pretty impressed. I think its a good deal $50 per cleaning return postage included.
