Fast-forward to 2021. This 90-250 mm f2.8 4/3 lens mounted with an adapter on either an Olympus OMD EM1 mk2 or EM5 Mk3, both with PDAF focussing by the way, and you have a dream combination of fast telephoto, sharp optics, and 20Megapixel sensor. Even excellent with the 4/3 1.4 teleconverter as well! 4/3 lenses live on and still deliver! with an effective (full frame) 252 – 700mm at f4.0 and with quick auto-focus.
It needs to be mounted on a solid tripod though, and it is preferable to set the cameras for first curtain electronic shutter (in the menu or Super Control panel) and with such a telephoto range a remote shutter release is mandatory to eliminate any possibility of camera movement.
