Ricoh Unveils New Pentax Medium Format Wide-Angle Lens, Mirrorless Camera


AUGUST 04, 2014

By Greg Scoblete

Ricoh is trotting out its first ultra-wide-angle zoom lens for its medium format 645 camera system aiming at landscape and architectural photographers and anyone else in search of a wide-angle of view. The HD Pentax-DA645 28-45mm F4.5 ED AW SR lens delivers a 22-35.5mm equivalent in 35mm format and features a rounded diaphragm for smooth bokeh. It offers a quick-shift focus system that lets you switch to manual focus after your subject has been captured by the camera's autofocus.

Here’s a look at some of the other features you'll find on the new lens:

  • Ricoh promises up to approximately 3.5 stops of optical image stabilization in the lens.
  • Weather-resistant body: like the 645 cameras themselves, the 28-45mm lens will be dust and rain proof with the company's Super Protect coating defending the front of the lens from water and grease smears.
  • The lens features both HD and Aero Bright coatings to reduce flare and ghosting under tough lighting conditions.
  • The lens includes 17 elements in 12 groups with two aspherical elements and two extra-low dispersion elements.
  • Ricoh will include a redesigned lens hood to accommodate the image circle of the 645. 

The lens will also be compatible with 82mm lens filters and will retail for $4,999. Look for it in late August.

Ricoh has also thrown a new Pentax Q-series mirrorless camera into the highly competitive market for compact system cameras. 

The $499 QS-1 sports a 12-megapixel back-illuminated CMOS sensor, a 3.2-inch LCD and 1080 HD video recording at 30 frames per second (fps). The movie mode on the QS-1 has been upgraded from previous models with the addition of Continuous AF mode, which lets you track a moving subject during motion recording, ensuring they stay in focus (this feature won't work with every Q-series lens, including the 06 Telephoto). 

For the fashion conscious, the camera will be offered in 40 (count 'em) color and grip color combinations. The exterior gets a synthetic leather front panel as well, a first for the Q series.
