Official: More Technical Information about the K-3 III


Claimed new improvements or new features include: 

- New viewfinder optics with a higher magnification factor of which the displayed image is also brighter, with the addition of a new condenser lens and with an overlaid LCD information display, too 

- New metering system with 307k colour pixels which has better metering accuracy and also helps the tracking of moving objects

- New high-speed mirror and shutter driving mechanism 

- New PRIME V processor and high ISO performance which is better than that of the K-1 II in terms of noise/details as well as reproduced colours (but that the ISO performance of the K-1 II is really rather outdated by today's standard, nonetheless). New Fine Sharpness II setting option is also made available for in-camera JPEG sharpening.

- New SAFOX 13 AF module of which the layout is shown in the below diagram
Legend: Red squares = Crossed AF sensors (25 nos.), Red and Blue squares = Selectable AF points (41 nos.), Deep Blue "circled" sensors = -EV4 low light capable and F2.8 lens aperture compatible (9 nos.)

But, I just wish to ask: How and what does these painted "new" bodies help Pentax and her fans?? :-(

Update (Feb 25): The K-1 II J Limited Special Site is now online (in Japanese only). It is mentioned that the golden lens mount is coated by Citizen Watch Co. with its "Duratect" technology. The wooden grip and its paint are also briefed.

The K-3 III is Delayed and Here Comes the Re-packaged 3 FA Limiteds in HD

We all knew that the K-3 III was delayed without a new release or market launch date announced. :-(

Hence, Ricoh is "kind" enough to let us have something else "new", right before the CP+. ;-P

Here we go:

(Source: Japanese Nokishita Twitter via Cameota. In short, the new features of the re-packaged FA Limited lenses are HD plus SP coatings, round aperture and blades and guaranteed -10 deg.C temperature operation, there is no Weather Resistance, nonetheless. Anyway, my old FA Limiteds have never had any problem working in cold and snowing conditions under -10 to -20 deg.C in the past, so did my other film FA lenses, but getting the lenses wet might cause real problems. As for the aperture ring and aluminium casted lens bodies, these are indeed good old features but nothing new.

Update (Feb 25): The HD FA Limited Special Site is now online (in Japanese only). Online pre-ordering from the Ricoh web store is also made available. The offered prices are not cheap, though.
