What if "downgrading" your gear, actually UPGRADED your photographs and your overall photographic experience? Whoa, mindblow.
Talley you are going to love the Fuji x system, as long as you look at it from the right perspective.
I also think if you are in the market, you are compelled to get the sigma 14....I would wait on reviews, or preorder and return for Laowa if you are not happy, but I think this will be the uwa to have if you don't already have one that is fine for you. If the 1.8 and bells and whistles are not needed, the 2.8 ex is an amazing gem of a bargain. I really like mine, but you need to stop way down to get sharp enough corners...like F8. 2.8 is tack center and very creative. I imagine the new one to be this on steroids and if sharp enough at like F3.5 that would make me consider the upgrade and take the extra "betters" as a bonus.
