I'm taking a trip to the middle east (Saudi + UAE).
I want to travel light so I'm trying to narrow it down to two lenses i can use with my Lowepro slingshot AW100.
One lens im set on, the sigma 30mm, it's my low-light sidekick and the equivalent 50mm field of view is so versatile.
For simplicity I'll highlight the contenders for my final slot:
Canon 17-55 f/2.8 :: This all-in-one is hard to put down. It does everything superbly and covers you in almost every conceivable way with IS and 2.8 aperture.
Sigma 10-20 f/4-5.6 :: My ultra-wide that I sadly have not used as much as I should. Paired with the sig30 there would be no overlap. Notable downsides would be lack of IS and narrower max aperture. Upside would be this lens can go from UWA to WA very easily. In daylight i see no issues with appropriate shutter speeds, for night time i would be forced to switch to the sig30.
other notes: i'm not taking a tripod with me.
so which lens would you choose?
