My first post here. I was wandering if there is any plane spotters out there that could give me peace of advice. I am looking a zoom lens, I mainly take pictures from Changi Airport T1 and now only at the middle section after they closed the runway side. I am thinking of getting Nikkor 55-200mm, is it enough. Camera is D50. Is it good to use teleconverter with this lens. Also if anyone could tell me where would be good place take pictures outside airport. I just don't have a car need to rely on PT. How about Changi beach.
