p.2 #11 · p.2 #11 · What to get? 100-400L 4.5-5.6 or 70-200L 2.8 with 2X extender? | |
I've had two 100-400s and never had dust or moisture problems with either, though as I understand it, most zooms move air in and out when zooming and the more rapid the zooming and older the lens, the higher the possibility of dust or moisture getting in.
I had that moisture problem with a 70-300 DO in the Australian tropics, particularly, I think, due to in and out of the AC in cars and buildings. It dried out periodically without any consequences, but was an annoyance. I liked the 70-300 as a travel lens, mainly what it was designed for, but always had those moments of it coming up short at 300mm.
In my experience, there is always going to be something, too long, too short, to heavy, too big, AF, IS, et cetera ad infinitum, so you either buy everything or make well thought out or best guess choices based on what you want to do and where you are coming short and live with the little stuff.
