I got the Spider Pro now good 3 weeks and am just thrilled. I use it on a Belt Tamrac. Had to test 3 days on a festival it now. The camera is secure and can be reached with just one hand. The processing of the Spider Pro is simply exemplary. No plastic and a super concept. Troz the high price I can only recommend the Spider Pro. You can tell him little, the hands free and also no disturbing backpack on his back. This is very pleasant in summer grade. Thumbs up
If it is still important: It is used with a Nikon D300 + Tamron 70-200 2.8
