In a few months I'll be going to Scotland for a holiday (highlands and so on). So far, along with my 550D I have the standard kit lens 18-55mm, and I have recently bought the 55-250mm II. I am planning to buy an other lens, either the canon 50mm f1.4 or the canon 10-22mm.
I like the 50mm because it lets a lot of light in and it can be used in the evenings without using much flash in low-light conditions, not to mention the delicious bokeh!. However I have always liked the effects of the 10-22mm as well. And I understand that it's more creatively versatile and I can use it for Scotland highlands and castles
Eventually i'll be buying both, but I am stuck over which one should I get before the holiday. Which lens would you get if you were faced with the same dilemma? Budget not an issue, preferably I just want to get one of those only before august!.
