Olympus E-M1 Mark II and Nauticam NA-EM1 II
by Phil Rudin

The Olympus E-M1 Mark II has been selected as camera of the year for 2016 by a number well respected reviewing sites and magazines who put far more time into pixel peeping than I do. So up front I would just like to begin by saying that I think the E-M1 Mark II is the best Micro43 camera available and that anyone interested in underwater photography should take a close look at this camera and the excellent Nauticam NA-EM1II housing system.
The E-M1 Mark II completes the hugely successful Olympus OMD series and is a brilliant successor to the E-M1 platform released in 2013. The E-M1 Mark II is the “Pro” end of the OMD lineup and the new Olympus agship camera. It directly targets Pros and high end enthusiasts who don’t mind shelling out $1999.00 USD (now $1799.99 at Amazon USA and others) for a highly capable and very compact camera body.
The Mark II is a compelling choice for DSLR users considering a move to a mirrorless camera system and for Olympus users wishing to move up from the Olympus E-M5 and E-M10 series cameras.

DxOmark tested the Olympus 25mm f/1.2 PRO lens and the conclusion is:

At $1199, the Olympus 25mm f/1.2 is not cheap, but you get a lot of lens for your money, with weather-sealed barrel construction, advanced optical construction, and a super-wide f/1.2 maximum aperture. Its excellent light transmission ranks it as one of the highest-scoring MFT-mount lenses we’ve tested on the E-M1 II, only fractionally behind the Panasonic 25mm f/1.4. It achieves a slightly higher overall sharpness score compared to the Panasonic alternative, however, and significantly less geometric distortion, which could be important if you want straight lines not requiring correction in post-production. Performance at the maximum f/1.2 aperture is good, but closing down to f/2 notably improves center resolution and reduces vignetting. For peak performance, consider shooting at f/4 or f/5.6 on the Olympus 25mm f/1.2.
