How about Pentax 645d?

Now the Pentax artifact. Large photosensitive element, high pixel, viewfinder field of view reached 98%, using a newly designed high-precision 1 1 point width SAFOX IX+ focusing system, with 9 o'clock in the center as the cross focus, accurately capturing the subject. TTL full aperture 77 differential volume metering system, multi-zone metering, central button metering and single point metering are adopted. It also has many functions of Pentax: custom image mode, HDR photo shooting function, electronic level, CTE white balance, reflector locking function, copyright information embedding and so on. However, due to its high price and limited users, there are few visible comments. However, as the flagship model of Pentax, it is also the dominant model of 645 at this stage. I believe she will not let you down.

Finally, praise 645, support!
