Any comments on this lens? I own the f2.8 version but would like something faster. Is sometimes/always/never multi-coated? How is corner sharpness compared to the f2.8? How is the bokeh?
I would like a fast 24 with good center sharpness wide open, and good corners by f8-f11. Unfortunately can't afford the 24L.
I'd like to see some full-frame examples if anyone owns this.
It apparently may not satisfy your wide open centre sharpness requirement, according to Gary Reese's tests.
24mm f/2.0 Zuiko (multi-coated)
OM-1 with mirror lockup
Vignetting = C @ f/2, B @ f/2.8
Distortion = pronounced waveform
Aperture Center Corner
f/2 C- D-
f/2.8 B C
f/4 B+ B
f/5.6 A B+
f/8 A A-
f/11 B+ A
f/16 B B
Notes: Easy to focus due to bright viewfinder image. Lens hood selection
critical since vignetting not predictable in viewfinder. Very contrasty
at f/5.6, contrasty at other apertures.
OM-4T with mirror and aperture prefire
Vignetting = D @ f/2, B- @ f/2.8, A- @ f/4 and thereafter
Distortion = moderate waveforming with strong barrel tendency
Aperture Center Corner
f/2 C+ C
f/2.8 B- C+
f/4 B+ B
f/5.6 A- B+
f/8 B+ A-
f/11 B+ A-
f/16 B B+
Notes: Moderately low contrast at f/2, moderate contrast at f/2.8,
moderately high contrast at f/11 and high contrast at f/4 to f/8.
Based on the WO centre performance of the f2 (if those results indicate what one can generally expect from the f2) I would either a) stick with the 24/2.8 and bump the ISO up one stop, or b) buy the 28/2, which appears to be a much better WO performer.
