Long time listener, first time caller!
Currently I have a 50/1.4, 70-400/4 and Tamron 28-75 on my XT. However I am going to London soon and think I will need something wider. I am debating between selling the (very good) 28-75 for the Tamron 17-50, or simply buying either the 10-20 or 10-22. I think the 10-22 plus the 50 would make a very nice light pair to walk around London, covering the wide angles along with good portrait/low light capability.
However the 17-50 upgrade would be cheaper!
Any thoughts would be appreciated. Would 17 mm be wide enough for the tourists spots of London?
Cheers
David
