In 1995 I purchased a Nikon N90s which was a solid workhorse for the next several years. It was slightly heavy for my geology field work so I eventually sold it on ebay.
In 2002 or so I purchased a Nikon N80 which I still use.
Other cameras that I have used include the tiny Olympus XA-2 for taking pictures while rock climbing, and a Canon Powershot A95 I have been using since 2005.
I never use all of these on the same trip. The 24mm is essential. The 35-70mm is a good all-purpose lens. The 60mm macro is incredible quality but bulky and heavy. For wildlife and some climbing photos I'll use the 70-210mm zoom. You can see the same area taken with
the 70mm
and the 210mm
