Good lord, are you people spending all your time shooting in a closet?
Waaaaaaaaaa!! Only f/2.8. Waaaaaaaaaa!! Canon needs to base all their market research, product development, and release cycles on my every whim! Waaaaaaaaaa!!
First, Canon announces this lens. You see no use for it in your personal contexts. Get over it and don't take it so personally. This is not the last lens that Canon will ever release. Just because they haven't updated your personal favorite, doesn't mean they never will. Seriously, STFU.
Second, by now it should be clear that anything wider than f/2.8 has to have some L-level build quality if you want great image quality. My 50mm 1.4 is great, but I only take it below f/2.8 either in extremely low light, which is rare, or if I purposely want very, very shallow DoF. Also rare. I know that not everyone's personal situation is exactly like my own, but good lord, aperture is not the be-all end-all. At $200 you're getting STM, FTM, decent build quality, AND round aperture rings.
Seriously, if you don't want it, don't f------ing buy it. It's not a difficult concept. Nobody really cares about your personal misgivings with Canon's release cycles and the direction they're taking with their products. The technology is getting better all the time, and we've no reason to believe that this lens will suck at what it does.
