Canon EF wide angle lenses
introduction
most seem to feel that older Canon's wide angle lenses don't really make the grade on full frame sensors
Canon has attempted to remedy this by bringing out mark II versions and their unique 17mm tilt shift lens
prime lenses
Canon EF 14mm f/2.8L
Canon EF 15mm f/2.8 fisheye
Canon TS-E 17mm f/4 tilt shift
Canon EF 20mm f/2.8 USM
Canon EF 24mm f/1.4L USM
-
84deg field of view; 0.25m macro; 77mm filters; 7 blades; RRP $A2800; ($A1869 online)
this is a great lens although soft in the corners on full frame
it is now matched in image quality by Nikon's new 14-24mm f/2.8G which has better corner sharpness
Canon EF 24mm f/1.4L II USM
Sigma ART 24mm f/1.4 DG HSM

close focus 9.8“
new full-time manual focusing mechanism

zoom lenses
Canon EF 16-35mm f/2.8L II USM
-
82mm filter allows polarisers without vignetting; weatherproofed; ($A2095 online)
corners almost as sharp as centre at f/4 on full frame but still soft wide open.
best resolution at 24mm but CA can be a problem
barrel distortion at 16mm
better image quality than the EF 17-40mm f/4L, but at 24-35mm, neither of these comes close to a EF 24-70mm f/2.8L
at last Canon has a lens that beats the Olympus OM 18mm but it still has problems in the corners on a full frame sensor.

74 to 29deg angle of view; 0.28m macro; 77mm filters or rear drop in; weather resistant; 7 blades; RRP $A1600; $US600-800 Ebay;
unfortunately significant distortion on the edges with full frame cameras.
Canon EF 20-35mm f/3.5-4.5 USM
Canon EF 24-70mm f/2.8L USM
-
RRP $A2700 great lens but no IS and its heavy.
reverse zooming mechanism with maximal extension at wide angle means lens hood is much more effective than the one on the 24-105mm
seems there is some variability in optical quality between lenses

Canon EF 24-105mm f/4 IS L
-
77mm filter; 670g; 3 stops IS; a great travel lens; RRP $A2000
similar image quality to the 24-70L but lighter, more range and IS thus better for stationery subjects whereas the f/2.8 on the 24-70mm means its better for moving subjects.
CA at wide angle f/4; not weather resistant; some vignetting on 5D at < 50mm focal length; more distortion than the 24-70mm.
