It will be an excellent walk around lens for FF, assuming the CA is good.
It could work well on my FFFilm Canon Elan 7n.
I normally shoot B&W (Kodak BW400CN,Kodak P3200 or Adox CMS20), so CA isn't a problem.
The lens I really want is the New Nikon AF-S NIKKOR 28mm f/1.8G iens for my Nikon F100 FFFilm
camera. Canon seems to have abandoned the middle
while Nikon has come out with three reasonably priced f/1.8 lenses (28mm, 50mm and 85mm) in the last year
I still wish that Canon will come up a EF-S 30mm f2.8.
That and an EF-S 22mm (=36mm). I'd buy them both.
