Like All OM/Olympus M.Zuiko Lenses the M.Zuiko Digital ED 25mm F1.2 Pro lens is exceptionally well made. One Driving factor with my purchase of yet another Pro Lens was that it had the fantastic clutch for switching from Autofocus to Manual Focus. The Bokeh is incredibly silky smooth across the entire F/ range from F/2.8 to F/16. THE BIG GRIPE is that it is too soft out at F/8-F/16 which to me makes this a portrait only lens and not the Ideal Full Frame "Nifty 50" equivilent. Ideally I would have purchased the 20mm F/1.4 pro lens to get a bit more of a wide angle as I find the field of view too narrow on this compared to my full frame sony. HOWEVER the 20mm had no clutch and did not review as well. PLEASE OM make a 20mm F/1.4 Pro with a Clutch. Or a 12-40mm Pro in F/2.0 But otherwise love my OM gear.
