I think I have decided to keep the Sony 12-24mm f/4.0 ultra wide angle lens. I’d like to write the review properly, unlike my other reviews, so it might take a while haha.
It’s a lens that doesn’t really get much hype, and perhaps people are a bit put off by spending that much on something which isn’t a GM lens. My initial impressions are that it’s incredibly lightweight but it doesn’t feel as plasticy as I was expecting. Think more along the lines of any typical poly-carbonate (Canon “L”) lens. I’ve never had a problem with plastic being used for lenses, providing it feel somewhat rugged, in fact, in some cases it’s nicer (your fingers won’t freeze to it like metal, haha).
I would say the biggest problem I have with it is that 12mm is very hard to frame with, even indoors. For example, it can make a living room look too big and the furniture too stretched out in the corners. For bathroom shots though, there’s a significant improvement over the 16mm focal length.
