Lighten your load
I forget when I switched from a digital “prosumer” or all-in-one camera to a DSLR but it’s been a few years. So, as often as not I drag my whole camera bag with me and end up shooting all my shots with just the camera and my 17-85mm lens. I did have an old leather holster style camera bag that I would use sometimes when I didn’t want to carry the whole bag of stuff. But, it wasn’t ideal. The fit was pretty snug. The only way to close the holster was with a zipper so it was pretty slow to get the camera out for a shot. The strap was pretty short so when I had the camera out the holster would always slip off of my shoulder.
Well, I’ve found a great solution and thought I would share it with you. It’s a Tamrac Digital Zoom Pack. http://www.tamrac.com/5683.htm
It’s just right for me when I only want to take my camera with the one lens. It has a zipper but also has a clasp for the cover. So, when I’m walking around I leave it unzipped with the cover held down by a clasp. It’s easy to get the camera out. It has nice long strap so I put it over my right shoulder and let the case hang down on my left hip. They have other models in case you have a longer lens.
