I have a 24 is usm lens, 40mm stm and also a 17 ts-e lens.
I usually use the 17 for the architecture, and the 24 and 40 for my backpacking trips because of the size and weight.
However, I need to get some images where i need wider than the 24 (wf shot, and i cant step back), and am loath to take the 17ts-e because of the bulk and weight of the lens.
Taking the 16-35 (615g) instead of the 17, 24 and 40 (1332g) makes huge sense ito weight and ease of use while hiking, however the 17 would only be used on the tripod while tenting and the 24 used while actual hiking, is a nice small package in the bag on the hip ( bigger bag is bulky and prevents good tensioning of the waist strap).
How good is the 16-35 verses these other lenses that i have?
ps i also like the sun-stars on the 16-35.
