Lens duster, lens cleaning fluid, lens cleaning anti-static clothes.
Tape head cleaner.
A good bag- this will protect it in its most common state (not being used).
uv filter to protect ur lens. Jamesnw mentioned the cleaning kit stuff...u dont have to buy them seperately just in case u dont know. the lens brush(duster), cleaning fluid, micro fibre cloth all come in the kit from any photography store. U can also check out some cleaning tutorials on youtube to see how to do it properly. Read ur manual also on camera care.
i duno what they're called really...it came in my kit. but it just uses normal air...u have to squeeze/pump it by hand and air is expelled through a small hole
honestly i just went into the photo store and bought a kit...duno what brand. they all do the same thing though and all above mentioned things are in it.U dont hav to worry...compressed air doesnt come in a kit, that kind of thing u pick up at a hardware store or something. Everything that comes in the kit is legit for ur camera.
I've been in the TV and production biz for over 30 years and have found that Rosco lens cleaner and lens cleaning papers are about the best out there and are reasonably priced. I've bought a lot of stuff from these folks and have never had a problem.
