. Who is going to buy a 28/2.8 IS over a 28/1.8? Especially when the latter will most certainly be cheaper.
The 28 1.8 is neither an especially cheap nor a very good lens. A Lot of lateral CA, and only the center sharpness is something to write home about, and only stopped down. If the 28 mm prime performs like a Leica, I will like it (pun intended).
To be perfectly fair, my 24/1.4 L II has a ton of CA. I think it's just the nature of wide, fast aperture lenses.
