Six different versions of the Pentax K-3 Mark III

Once upon a time I also wanted a monochrome K1, but I changed my mind, because monochrome sensor prevents CA correction unless the lens is a Pentax lens with auto-correction in camera or in PP software such as DXO. If the lens is an non-Pentax lens , or old manual lens, CA correction isn't so easy and uncorrected CA will affect sharpness of high contrast edges of the monochrome images.

Good point. I'd still take one though. The increase in resolution is worth it IMO.

How should CA auto-correction possibly work with no separate colour channels to start with? All it can do is reposition pixels in single channels in relation to the others. Moreover, according to my tests, applying CA correction causes a loss in resolution rather than a gain. However, this may depend on the CA characteristics – e.g., it may be different with a lens expressely designed to be used with built-in CA correction. But I strongly doubt that CA correction will make old manual lenses sharper or higher-resolution.

I think you are right, CA can't be corrected with monochromatic sensor assembly, the lens has to be excellent. My experience of Pentax lenses (K1) is that CA can be significant, a few pixels wide, uncorrected color fringing is much less visible once in B&W, it mostly shows as less sharp edges.

According to Pentax rumors, Ricoh will release 6 different version of the Pentax K3 mk III.

Designer colors?

Mostly yes. It's a nice way to extend product life cycle, with limited engineering efforts.

Only “6”? Sure, I’ll wait!

I don’t care about red or blue bodies. I’m not interested in premium editions. I just want the K1 - style articulating screen. 95% of the development work has been done!

If they gave me an option for a Limited-like Silver finish (the one on the J-Limited LX75 version of the K-1) I'd happily pay a hundred euros extra just for the different color (and considering an entire car has paint jobs cost 250-600€, so yes, 100€ is expensive XD)

The K-3iii is the newest Pentax camera.
Why are they thinking in terms of extending its product life cycle already???

I would take the gunmetal with modified shutter release, don't know what the latter means but I want something thicker more retro style. I like chrome body, but all Pentax current line up of DSLR in chrome are looked like plastic to me, I want something looked more "muscular" and metallic so gunmetal is the one for me.

From someone using a Pentax 67 for BW photography a k3-3 with a monochrome sensor will save me a lot of $$$ in film and will help the environment xD. That move can undercut Leica monochromatic camera if is priced well.

Count me in as part of the 40% crowd

From what I can deduct that would add another 40% to sales from us Pentaxians that are still waiting for our real "Flagship" model to finally arrive !

Which begs the question, exactly what is the point of bleating about it? Accept it and move on. If it's that much of a strain, I'm pretty sure other manufacturers can give you a well built camera with a movable screen.

Maybe it didn't sell as much as expected due to being released during covid. Once covid is over, it's a good time to redo some promotion for the same product again.

Probably just different colors and/or color combinations for the Japan market.
