My Favorite Wildflower ID Reference:



I use this book extensively for my Idaho trips. This is the updated 3rd edition; I have the 2nd edition.



My go-to lens for wildflower photography:



I use this remote release - helps ensure sharp photos:



This is the tripod I use:



This is the replacement for the 486RC2 I use.
If I were buying now I would purchase this tripod head.



I used a Nikon D7000; love that camera. Here is the newer version:



My wife's camera:



My primary camera bag (I have the older 100 AW); I carry a D7000 with lens, 2 or 3 other lenses, SB400 flash, batteries, car keys, Clif Bar, etc in this pack:



I use a Pelican case for canoe and air trips. The 1450 fits under airplane seats and my canoe seat. I carry the 120-400 zoom and up to 3 other lenses as well as the D700 body, SB400 flash, and a few spare batteries in spaces carved out of the foam.



My wildlife / grandson-football lens. It has a spot in the Pelican case:



My wife's lightweight "outdoors lens." She let's me borrow it for backpacking trips.











Included in my "library:"
