Long time lurker, first time poster. I did a search for this topic and couldn't find anything close so I'm starting a new thread (sorry if I'm duplicating). In two months I'm going on the trip of a lifetime: a week in the Galapagos Islands and a week in Machu Picchu. I'm a fairly serious amateur photographer, shooting primarily landscapes (some in HDR) and wildlife. Unlike trips to places like Florida, etc. to shoot birds, a missed shot on this trip is a missed opportunity that won't come back because I'm not going next year, or probably ever. Given that, I want to make smart lens choices.
I shoot with a D90 body and am planning on bringing the following lenses:
Nikon 18-200 — I own this and use it a lot and the familiarity will probably be an asset as I know just what it can and can't do
Nikon 105 Macro — Also my lens; I love shooting small stuff tightly and the colors I've seen on the Sally Lightfoot crabs and other bugs down there are stupendous
Nikon 12-24 f4 — I figure the wider the better, right? I can rent this from a local shop for about $100+ for the trip. Seems a shame not to have something this wide.
Nikon 80-400 — A good friend has generously offered to lend me his. I figured with the bird life and the restrictions to stay on the designated paths in some parks a lens with this kind of reach would be great to have.
So here's my question(s) to those who have been, or who might otherwise have an informed pov:
Am I nuts to carry around that much glass (I have an outstanding camera pack and do a lot of running so I'm not worried about stamina)?
Am I missing anything or should I be considering other possibilities?
Does anyone have any experience bringing long lenses into Machu PIcchu? I've read some of the urban legends about the $300 pro shooters fees, but would love to hear from someone with direct experience.
