Pentax 645Z Officially Announced
New 51-megapixel medium-format DSLR · Posted on 04-14-2014 in Pentax News
The 645Z teaser has ended as Pentax has just officially unveiled the new Pentax 645Z medium format DSLR, the 51-megapixel successor to the 645D, originally launched in 2010.
This professional DSLR boasts a new CMOS sensor that delivers a big jump in image quality and resolution compared to the 40-megapixel CCD chip that came before it. The ISO range of the 645Z will be an impressive 100-204,800, up from 200-1000 (100-1600 expanded) on the 645D. At an MSRP of just US $8,499.95, the 645Z promises to be a very compelling option for studio and landscape photographers craving ultimate image quality, as its sensor specifications place it in a league above 35mm full-frame without the steep price tag of other medium format systems. This launch price is 15% lower than that of the 645D, and it marks an industry low for a medium format DSLR.
Other features new to this camera include live view, full-HD video recording, and a tilting LCD screen. It has received an upgraded 27-point autofocus with sensitivity to -3 EV as well as a highly-accurate 86k-pixel metering system. It can also be remotely controlled via the optional FluCard accessory, or desktop tethering software. Pentax is able to keep the price of this very serious camera down by sharing hardware between it and the Pentax K-3, the company's APS-C flagship. Another shared component is the PRIME III imaging engine, which offers increased processing speed and responsiveness compared to earlier cameras.
While the 645Z shares the same form factor as the 645D, it has received an updated button layout to accommodate the presence of video and live view. The shutter mechanism has also been improved, now offering a maximum frame rate of 3FPS, up from 1.1FPS. The dual SDXC card slots now support UHS-I memory cards for faster read/write speeds. The 645Z continues to be fully weather-sealed.
As a medium format camera with a 44x33mm sensor, the 645Z uses lenses that are larger those for traditional 35mm or APS-C DSLRs. The camera body is also considerably larger in order to facilitate the wider lens mount, large mirror, and optical viewfinder. As a result, the 645Z has a number of additional controls as well as two perfectly-flat tripod mount surfaces: one on the bottom and one on the left side. This makes for easy changes in orientation without affecting the camera's center of gravity.
