Hello, I'm planning on buying a Canon 5DII with a wide zoom and a tele zoom for some free-lance photography next to my full-time job (not as a photographer). I will be basically doing some journalistic work, indoor portraits and events. Once I have premium equipment, why not make full use of it and take it on holiday. My question is, will a 70-200 f/2.8 not be too cumbersome for holiday? With 1.4 extender I can even shoot wildlife with it. If it is, I will consider 70-200 f/4 for work but will miss out on reach as I don't look forward extending the lens to 100-300 f/5.6. I will then have to resort to the plastic 70-300 with variable aperture, which forgoes the whole point of a full frame body. 100-400 is not really an option either since it's even more cumbersome than 70-200 f/2.8, isn't it. The other option is to forget about it and buy a crop camera with cheap lenses for travel. But that will not save me any money and in fact I'm spending more to end up with worse gear. The only thing which keeps me from hauling the 70-200 f/2.8 with TC1.4 is weight. So, is it an issue or not? PS: the tele zoom will be paired with a wide zoom, either 16-35 f/2.8 or 17-40 f/4 (I'm leaning towards the latter). Advice welcome.
