PENTAX 645D

Pentax-645D-Front camera
A full five years after announcing its
development, 2010 has seen Pentax finally unveil its
much anticipated 645Dmedium-format digital camera – and
to reveal that it will finally be available in the UK by the end
of the year, having been available only in Japan. It features a
40MP, 44 x 33mmCCD image sensor, 921k-dot 3in LCD
and is compatible with the existing PENTAX 645 systemlenses.
We’ve finally got our hands on one (see our full pro review
in our January 2011 issue), and it seems to have been
worth the wait. It features a lightweight, but solidly built,
body comprising a magnesium-steel alloy frame,
reinforced glass LCD panel protectors and a well-produced
dustproof, weather-resistant construction.
The high-performance CCD image sensor has, perhaps
surprisingly, been produced by Kodak and measures
44 x 33mm – that’s approximately 1.7 times larger than
its 35mm-format counterparts. The newly-designed
shutter unit has a top speed of 1/4,000sec, which Pentax claims can
withstand as many as 50,000 shutter releases. The PENTAX 645D
also boasts dual SD/SDHC card slots, a newly-designed, 11-point wide-frame
AF sensor, a 77-segment multi-pattern metering system
(for super-high-accuracy light metering), the DF-80
Natural-Bright-Matte focusing screen… and on, and on
and on. Will we fall in love with the PENTAX 645 in the same way we
did the analogue 67? Only time will tell. But for the
moment we are just glad that it exists and that it’s here.
