Hello all. First off, I'm new to this site, so hello to you. Photography is a hobby for me, I unfortunately don't have any room in my class load to even fit an intro photography class. I've been shooting with a Canon A310 for several years and have loved it, but I'm currently going crazy with the limitations of this point and shoot. So I've decided to step it up and get a Nikon D50. It seems like the best choice for quality and not hurting my college student budget too badly. I'm a pilot and would like to eventually get a powerful enough telephoto setup to do some good plane spotting. I'm also very interested in nature photography, and shooting around town (especially at night). I've been doing a lot of reading on line and think I have figured out a decent setup to start working towards. So here it is. Please comment on any aspect of this as I basically know nothing and will probably need help. So I will start out with the D50 and stock 18-55mm lens, obviously also with a nice SD card and case. Then I was hoping to match that with the 55-200mm nikkor lens, followed by the 70-300mm ED nikkor, and the TC-201 2x teleconverter so that I have up to 600mm capabilities. Each of these purchases would be several months apart and hopefully give me time to become relatively proficient with each step up. With the ultimate goal of being nicely setup for the airshow season next summer as well as all the normal shooting I do. What advice can you all offer on these ideas? And also, what else would you suggest as far as necessities for starting off. I have a basic understanding of most of the concepts at work, but I'm sure I know basically nothing about doing all of this in a practical setting. Any help is greatly appreciated, and sorry for the short novel of a post.
