That title should generate a few extra clicks. Look at the telephoto lens he is carrying, a serious birder. Back in my 35mm film days, the longest lens I owned was a 200mm. I had a couple of them, a 200mm, and 100-200 varifocal zoom (the focus remained constant as you changed the focal length of the lens.) When I bought the Nikon I am using, I bought a bundle that came with 2 lenses, the longer of which is a 70-300 zoom, but on a "crop sensor" format, meaning at the top end it is the equivalent of a 450mm lens on a 35mm film camera. I have been surprised by how much I use the longer lens, and how much I use it at it's limit. This is strange, back in my 35mm days my favorite lens was a super wide angle 24mm. I now have a 10-20mm lens, that is even wider. I seem to view the landscape in narrower clips than I did before. I hope this is a sign of being more focused and not on becoming narrow minded.
Should I get a bigger one?
