I'm planning yet another trip to Costa Rica (over a dozen now). Each trip I try to improve a little bit more on my photography skills. My primary interest when there is shooting wildlife such as monkey's, birds as well as more "macro" type objects such as poison dart frogs, flowers and other very small critters. I've attached 2 samples from previous trips. Previously I would carry around my Canon camera (currently using the 60D)along with 4 or sometimes 5 lenses. Hiking in the warm and humid rain forest for 5 or 6 hours or more makes that very tiring. I currently own these lenses:
Canon 70-300mm "L" (one of my favorites)
Canon 100mm macro (the more expensive version)
Tamron 24-70mm (weighs a bunch and use that as my primary all purpose lens)
Canon 24-105mm (back-up to the Tamron)
I recently watched Tony Northrup's video on Macro and learned about diopter's and extension tubes (I have no experience with either of those). So my question is, am I better off carrying around 2 or 3 lenses and constantly switching as needed or is there any effective combination of the above mentioned lenses that can be used with extension tubes so that with 1 single lens I can capture the types of images I submitted as examples. Bear in mind too, this is for pure hobby. I'm not looking to sell or market high quality professional photo's but just want some be able to take best possible photo's for my own and friends enjoyment. Thank You.
