I have a 16, 35 and 50mm but I'm beginning to wonder if I'm over-equipped. I don't plan on using the 55-200 when I get to go away on city breaks soon, just the primes, but I find myself mostly using the 35mm. I'm getting tempted to bring one body and one lens as an experiment. A standard lens has this strange effect of forcing you to spend more time considering each picture. And taking more pictures. You could get yourself a 35mm 1.4 secondhand within your budget with money over for a few coffees. Is that a controversial thing to suggest?!
