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II in terms of noise/details as well as reproduced colours (but that the ISO performance of the K-1 II is really rather outdated by today's standard, nonetheless).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.

The LA-KE1 is Delayed

See this previous announcement made by the manufacturer, the LA-KE1 is delayed:

(in Simplified Chinese)

The reason of the delay is about the shortage of chipset used in the adapter. It was promised that the first batch of the adapters should be shipped by 1 Feb.

Let's wait and see how it works and performs.

BCN Japanese Camera Market Shares in 2020

Surprisingly, there is a slight increase of the market share by Ricoh in +0.6% when compared to the previous year. Congrats, Ricoh! ;-P

Monster Adaptor (Pentax K to Sony E) Pre-production Reviews

 1. https://mp.weixin.qq.com/s/4ekKr7wJePbjEOcf01lWaA

(in Simplified Chinese, Google English translated page here - but there will be no picture nor video as the Weixin server has disabled hot-linking from other websites)

The video clips for the AF tests with the FA31 are dead links anyway.

2. The below YouTube video tested the Monster Adaptor with the DFA*85/1.4 lens, it seems that the new SDM motor as well as the KAF4 electromagnetic aperture are both well supported by this version of the adaptor:


The AF speed and response of the combo looks good.

SAFOX 13 (in K-3 III)

Credit: Mistral75 @ DPR Forum


Grey squares - Selectabe crossed AF points 
Hollow squares - Selectable linear AF points 
Small circles - Non-selectable linear AF points 

Btw, Mistral, where did you get this diagram? :-o It must belong to a product story later!  ;-)

Update (Nov 9): 

Mistral75 advised in his reply (via his latest comment below) that the above SAFOX 13 layout was a sensible guess based on the original official diagram showing cut-outs in the lines (as broken lines) of the finder marks and brackets, which was actually a collaborative work created among three members in the French CDI Forum.

To verify if this could be really true, I have made a new overlay diagram with their assumed SAFOX 13 with an official SAFOX 12 one. Note that with the new magnified APS-C viewfinder of the K-3 III, now the covered AF areas of the K-3 III and the K-1 are more or less the same, except the extreme peripherals:

My own wild guess Pentax has opted to keep the old SAFOX module and add/build new AF points based on the old AF module, since the number of crossed AF points remain unchanged, i.e. at 25 nos. 

In this connection, I don't think the above brand new layout is completely an accurate guess. Instead, a 5x5 crossed AF points surrounded by another 6x6 linear AF points in alternative / interlaced manner would be more sensible. As for the remaining linear 40 points, they can be put/added at the two sides as well as at the top and the bottom, surrounding the central part of the AF point crowd, making up a total of the 101 points, which are all visible and selectable in groups.

Besides, just for the sake of seeing what the SAFOX 12 would look like if it is yet put into the K-3 III, the following overlay diagram is also made:
