Okay, the Olympus OM 1 is here.
This review was done with a pre-production camera so it may improve even more by the intro date which is today. It is the last camera to carry the Olympus badge as an homage to the original OM 1 which is 50 years old this year.
Improvements in auto focus speed and tracking, combines all the EM1 mk III features plus adds digital ND filters up to 6 stops, starry night auto focus, subject tracking for cars, trains, planes, motorcycles and wildlife plus birds. Thanks to the new stacked sensor everything is faster and it has a new image processor (nobody talks about image processors enough, they're the heart of image quality). Thanks to the new sensor any advantage FF had on dynamic range and high ISO noise is effectively eliminated.
All in all a very nice package that holds a lot of promise for future firmware updates and next gen successors.
Is it worth the $2200 US body only? Absolutely if you're upgrading from a gen1 or 2 OMD or changing systems. For myself, shooting a 1 mkii, I'd love to have the ND filters, the subject detection, improved menu system, improved hi ISO performance and speed (speed's always good) but two grand is still too steep for those improvements considering my shooting style and preferences. YMMV.
