Ricoh reveals 51.4-megapixel Pentax 645Z medium-format DSLR

Just a few months ago, there were no medium-format cameras with CMOS sensors. Now, it feels like we can’t spin around in a camera store but bumping into one. Following prohibited on a heels of a Hasselblad H5D-50c and Phase One IQ250 is a Pentax 645Z, from Ricoh Imaging. An refurbish to a Pentax 645D, a new US$8,500 medium-format DSLR facilities a 51.4-megapixel CMOS sensor, a far-reaching attraction range, and Full HD video recording.

The 51.4-megapixel CMOS sensor during a heart of a 645Z measures 44 x 33 mm. This creates it about 1.7 times incomparable than that of a 35mm-format full-frame sensor, and a same distance as that in other new medium-format shooters. However, by pairing it with a PRIME III imaging engine, that initial debuted in a Pentax K-3, Pentax appears to have been means to fist extremely softened opening out of it, than a rivals.

The camera boasts a series of specifications that are roughly unheard of in a medium-format market. It has an ISO operation of 100-204,800, enabling sharpened in lighting conditions that allied cameras would be frightened of, and can hit out bursts of 10 RAW or 30 JPEG images during a speed of 3 fps. While that competence not sound like most compared to a likes of a Nikon D4S, it’s twice a speed of a medium-format rivals. Again removing one adult on a competition, a Pentax 645Z can also record Full HD video during 60i/50i/30p/25p/24p.

The Safox 11 autofocus system, that also featured in a Pentax K-3, has 27 concentration points, including 25 cranky type. It’s pronounced to perform good even in reduce light situations, and has a operative operation of –3EV to +18EV. The Pentax Real-Time Scene Analysis System, that consists of an RGB light-metering sensor with 86,000 pixels and a fine-tuned algorithm, is on palm to safeguard softened exposure-control, white-balance adjustment, and extended autofocusing accuracy.

Measuring a strong 156 x 117 x 123 mm (6.1 x 4.6 x 4.8 in) there’s copiousness of space for all a controls that you’d design on a camera of this standard. The visual viewfinder on a back is assimilated by a 3.2-inch sloping LCD with 1,037k dots, that should make it easier to fire in a accumulation of situations, and can also be used for live view. On a tip there’s a vast monochrome LCD for displaying sharpened information, and there are twin tripod mounts for regulating a camera in landscape or mural positions.

With a strong build quality, a 645Z promises to be a truly go-anywhere medium-format camera, if we don’t mind a 1,550 g (3 lb 6.7 oz) weight, that is. The extraneous housing and a LCD guard support are done of stout nonetheless lightweight magnesium alloy, while a framework is done of die-cast aluminum. Like many other Pentax DSLRs, a camera is weather-resistant and dustproof, with 76 seals practical around it. It’s also cold-resistant opposite temperatures as low as -10°C (14ºF).

While it lacks a built-in Wi-Fi ability of a Phase One, a dual SD slots of a 645Z meant it is concordant with both Eye-Fi cards and a FluCard for Pentax, that we have seen with a K-3. The latter allows users to recover a 645Z’s shutter, check a live-view image, and crop and download images accessible on a label with smartphones regulating a iOS or Android apps. There’s also a choice of regulating a USB 3.0 tie for some-more tethered control.

The Pentax 645Z will be accessible from Jun for a cost of $8,500 for a physique only. While that competence sound like a lot, it’s value remembering that a Hasselblad H5D-50c and Phase One IQ250 come in during $27,500 and $34,990 respectively.
