IS vs 1.4 ... imagine group shots or DOF needed for food shots (without using up your ISO)

I use f/2 on both my 28mm f/1.8 and my 50mm f/1.4.. on the 28mm f/1.8 because it reduces the CA a bit and sharpens the lens up quite nicely (I say it "crisps" it a bit) for a small tradeoff in speed... On the 50mm f/1.4 because the slight extra bit of DOF seems to be helpful.... f/1.4 is nice sometimes, I wont lie, but in general they spend their lives at f/2-f/2.8

I'm not in the market for a 35mm lens, but even if I were, I'd probably skip this unless my goal was to travel light (i.e. without tripod) and get the extra stops for stationary stuff.
Lawl, I rarely use a tripod, So for me, IS is never a detriment, and this is a walkaround lens for me (It goes on my 7D, my 7D goes in my go-everywhere bag) No problems taking my Sigmalux or 15-85 around with me all the time mind you, but I do prefer the 28mm f/1.8 or the 35mm f/2 on there because of size (Otherwise theres not much space in there if i say, buy something and wanna toss it in there)

Chief complaints on the 28mm f/1.8 are CA, flare, and yeah i concede its not the sharpest lens in my bag where I use it most often, Also the aperture is not rounded which means my bokeh balls usually end up not so ball-ish... good lens that grew on me though
Complaints on the 35mm f/2 are basically the bokeh can be VERY distracting when I shoot food and that.. it goes all nasty and double visioned looking....overall the lens itself I did like, and if i shot more distant subjects id take the 35mm f/2, but for what i tend to do the 28mm f/1.8 works better for me..
The Sigma 30 has a poor MFD which is why i returned it, Great optically however
As for the 35L I hear great things, its just the price thats kept me away, A few hundred difference is still a difference you know 
No real complaints on my Sigmalux though, I love that thing... its just 50mm, and for food, 28-35 is more comfortable on my 7D
