I am an animal biologist and I work as a herpetologist out in Indonesia. I want a lens to be able to take really sharp and detailed photos of animals I catch and I'm working on up close (i.e. monitor lizards, pythons, smaller snakes). I need photos for scientific purposes (for example scale counts later on), so I need good detail and sharpness. I will take a combination of both up close head shots ventrally and dorsally as well as whole organism shots. I have recently bought a Nikon D51000. Can someone please advise which lens is best (35mm, 40mm, 30-200mm, 50-300mm etc). My budget is 100-200 GBP. Any advice would be massively appreciated.
Thank you, Josh
