Just sold a computer and now I want to spend the money on some new camera gear. I got a few ideas. Thought I'd get some feedback. Tripod: Just sold my old POS slik tripod. It was too small and the head eventually broke. I'm looking for something light weight and simple. I'd take it backpacking so I don't want a big heavy one. I'd like it to be able to get to at least 5.5ft tall. Any ideas? Main Zoom: Right now I've got the 18-135 nikon kit lens. It's slow to focus and just a slow lens in general. Any ideas for a better quality faster lens? Doesn't need to zoom as far but I'd like to keep the wide angle. Macro: I've been eye ballin the sigma 105 macro. Is there another one comparable I should be checking out? You thoughts about this lens in general? Thanks for the feedback.
