|Canon EOS-1D X Mk II full frame camera|
As a wildlife photographer using Canon equipment for 25 years and the EOS-1D series since 1989, I have followed the line with keen interest for many years. My biggest 'complaint' about the camera is the 18MP sensor does not offer enough pixels when it comes time to crop the photos. Since the EOS-1D X camera went into production, a few technological advancement have been introduced, including new processors, sensors and Dual Pixel CMOS AF system, etc. Canon plans to introduce the EOS-1D X Mk II some time late 2015 or early 2016.
Pre-production models are already in limited circulation among photographers who signed non-disclosure agreements. The Mk II camera will employ a new, higher pixel sensor, perhaps in the low to mid 20MP, with an unparalleled AF system and improved ergonomics. Rumored to be slighter larger in size but perhaps maintaining roughly the same weight due to improvement in material and a new battery. The main processor may be either the souped-up, dual DIGIC 6+ or even the DIGIC 7 with additional processor(s) for an advanced metering system. Dynamic range is rumored to surpass any DSLR on the market since Canon still has to 'catch up' with the dynamic range of Sony's best sensor, for those who chase the numbers.
An unparalleled high ISO performance and new AF system will be most welcomed. The upcoming Nikon D5 is rumored to have 173 AF points. Canon will offer a brand new AF system on the new camera, with many additional AF points and more importantly, unmatched number of double cross type points. A new viewfinder may accompany the new AF system. Canon has experimented with OLED displays on their test cameras and it may be considered for the Mk II as well. The new camera will be an evolutionary step up from the Series I model. Canon is known as a conservative company and occasionally breaks their mold but I am always prepared to be surprised. Keep checking back for the latest information as I receive them.
