50mm equivalent lenses have a special place in Sebastian’s heart and this is hands down the best 25mm (2x crop factor) lens for m43. Tack sharp wide open, with only minimal color fringing this lens puts most full frame 50mm lenses to shame.
A special feature of the PRO Olympus lenses, this lens has a clutch type focus ring. In the forward position it operates as other fly-by-wire focus rings. But pull it back to go into an old school manual focus mode, complete with focus markings! The focus throw is a bit short, but compared to other autofocus lenses pulling focus on this lens is a dream!
This lens also supports smooth aperture changes in video on the GH5 and EM1 mk2.
