What is the best way to store a SLR camera and lenses?
I just got a nikon d3000. I love it, but I'm very picky with keeping things nice and clean, but you want the camera to be better protected. I'm new to the SLR scene, I store the camera with the lens attached camera bag? separately? I thank all caps, both camera and lens. I bought a nikon camera bag to help protect it. I was just a little concerned about traveling with the fixed lens with the camera. not want to break something. thanks for all your contributions.
First of all, never, never store your camer and lens camera bag when not in use for a long time, especially if you live in a humid climate. It is recommended to store your lenses in places without air stagnant, or within Dry in a cabinet with a controlled humidity level. Keep in a bag (or closet) only visually impaired fungus growing on your lens. If you live in a very dry climate then this can not be apply, provided they do not remain long in her purse. As to whether the lens is attached, well, if you do not need to carry it out, not take it out, dust will only enters.
