Summary: This lens is amazing. Super sharp eve wide open, with excellent creamy bokeh and beautiful vivid contrasty colours. I think the best way to describe the image quality is that it is creamy smooth with a 3D look.
Pros: Super Sharp even wide open., Creamy bokeh, Vivid contrasty colours, 3D appearance of the image., It's like a "standard" lens on the *ist D/DS., Superb build quality.
Cons: I little large for this type of lens., Price
Summary: I pointed the lens directly to the sun at 4pm, no flare was found on slide. Excellent flare control. Almost no distortion which may be due to 31mm, not too wide. Vignetting is very very little at wide open. Sharpness is also very good. Very well built lens body.
Pros: Excellent in all aspects!!!!
Cons: Price, paid HK$5900. But I want to keep a whole set of limited lenses, OK then.
Summary: Le 31/1.8 Ltd est un objectif fabuleux avec une finition extra. Tout métal, il tient bien en main tout en restant très compact. Sa construction respire la qualité. Le piqué est très bon et les images qu'il délivre sont bien contrastée.
