I will be traveling to Europe and am wondering which of my lenses to take with me. My kit includes a 550D, Canon 18-55 kit lens, Canon 55-250, Canon 10-22, Tamron 17-50 VC, Sigma 30mm, Canon 50 1.8. (Yes, I realize I have some redundant lenses that I have yet to sell). I also just bought a tripod for self portraits of myself and my wife (typical shots in front of Eiffel Tower, Pisa, Colosseum, etc).
I will take the 10-22 and 55-250. I am wondering about the mid-range. I want to travel light. I am thinking of the following options:
(1) sigma 30mm (sharpest)
(2) tamron 17-50 vc (most versatile)
(3) 18-55 kit lens and 50 1.8 (size, size, size....wouldn't worry about throwing it in the day pack since they are so light and cheap)
I am trying to avoid taking both the sigma 30 and tamron 17-50vc. I would like to take a maximum of 3 lenses, unless it's the 50 1.8 as it's so small. Please let me know your thoughts? Do I even NOT take the 55-250 and 50mm would be long enough? Or any other combinations that I haven't considered? Thanks in advance!
