I have been a fan of micro four thirds cameras since buying the original Olympus OM-D E-M5 when it was first released and challenged the current thinking on DSLR cameras. I’ve since sold my Canon APS-C and full frame gear and have been a big supporter of mirrorless cameras from Fuji, Panasonic, and Olympus with Olympus being my mainstay. My current system cameras include the Olympus OM-D E-M1 and the OM-D E-M5 Mark II with a full range of M.Zuiko lenses. I love it and even though it’s a compromise between low light performance , tracking speed and ISO noise quality over camera size, cost of lenses, and focus speed–it’s more than good enough for my needs.
I recently sold my Fuji XT-1 andX100T in anticipation of buying the Leica Q and now I’m wondering if I should have kept the X100T given the cost-quality performance comparison between the Q and the Fuji.
At any rate, this article is a good summary of what I love about micro four thirds lenses. The primes and the Pro zooms will go head to head with some of the best glass from any other system or manufacturer.
