Dual IS - optical IS synchronising with sensor-based IS to give unprecedented 5-6EV effectiveness

Video shot with the 300mm plus MC14 to show how amazing the IS is at 840mm field of view!

The Olympus 300mm f/4 compared to the Canon and Nikon 300mm f/2.8 - far smaller but it is 1 stop smaller but the field of view is actually 600mm.

That's one reason why Micro Four Thirds is far more fun and less burden!

It will be interesting to see how well the Olympus 300mm f/4 Pro lens competes with a Canon 7D II with Canon EF 400mm f/4L IS lens for birding - the Olympus will probably have faster AF for static subjects, face recognition AF, better image quality edge-to-edge, perhaps better IS, will be far less heavy and less expensive but maybe the Canon will do better C-AF tracking of birds?

introduction

  • finally became available in March 2016
  • equivalent fov to a 600mm f/4 lens on a full frame dSLR
  • similar size and weight to the pro full frame dSLR 300mm f/4 iS lenses such as Canon EF 300mm f/4 IS L lens but instead of only 2 EV image stabiliser the Olympus gives 6 stops of 5-axis dual IS, closer focus with much better macro capability, and much faster and more silent CDAF, less flare, plus it is likely to be sharper as it needs to operate at a 2x crop factor level giving 600mm field of view, and sharper again when used with a 1.4x teleconverter when compared with the Canon 300mm with 1.4x TC.
  • if you are shooting action in low light, an f/2.8 lens with a larger sensor for better high ISO performance may be your better option, but that means much more money, weight and size.
