Bring your camera gear to the store. See how a loaded bag feels on your shoulder. Check the shoulder straps; look for good hardware and better padding.

Over time, you'll add lenses, extension tubes, light meters, and other gear. A bag that's snug for a basic kit today won't carry it all, so plan ahead.

Vinyl isn't durable. Cordura or ballistic nylon bags—as well as reinforced cotton-duck canvas models—work well.

If you have rugged foam, a razor knife, and a sturdy backpack or travel bag, make your own gear bag. Carefully cut holes sized for your camera, lenses, and other gear. Find crumble-resistant foam at an upholstery shop.

Even bags with built-in rain gaiters get wet in a downpour. If poor weather is imminent, invest in a box of gallon-sized, heavy-duty zip-top storage bags, and put each piece of gear in one.

For pro-quality gear, visit camera shops. Online photo retailers often have deals on discontinued bags. Online auctions are fun, but ask the seller about wear-and-tear before bidding.
