Should I lug a huge 500/600mm around?
Bird photography interests me but the problem is that I was concerned about whether it would be alright to get to 400mm max, because I've seen thousands of bird pics that require longer lenses. I'd like to know whether for general use of bird photography in Hong Kong, say forest birds, whether 400mm is enough? If not, how long? It's just that carrying a huge lens everywhere do cause problems of weight (especially when hand-holding) and for my wallet. What would be one's opinion for, say, 300mm f2.8 + 2x teleconverter?
