Great news, looking forward to Chris and Jordan videos! Including the staple Pentax-dunking and end of year best and worst gear special!

Thanks for the samples, they are very impressive and a good reminder of what can be achieved with LF.

And no, i can't do that with my 50/1.2 on FF, nor with a noctilux (if i had one).

Is that proper pixel-shift, like with Pentax software, or are they processing each image individually using common de-bayer processing and stacking the images?
How about Pentax support? Thank you.

I'm guessing they make so many phones that it's hard to produce enough sensors for them? They are No 1 smart phone manufacturer worldwide.

Whereas Sony... do they still make phones? Sony has sensors to spare, enough for themselves, and Samsung, Nikon, Pentax, Fuji, Hasselblad, and many others...

It might also explain why Samsung backed out of the mirrorless camera business. They certainly had the technology to make an exceptional camera, but their resources were probably better spent elsewhere.

Jhaakas: This HDR feature is best suited for mirrorless/smarphone cameras. The mirror has to 4 times and that sure is a delay unlike the exposed sensor where it is in instant succession. It is still amazing result.. but it is a limitation of slr. The photo shown is not convincing, too many blown highlights especially in the yellow, orange areas and on while sign boards.

Regular PS uses the electronic shutter, I'm not sure why they use the regular shutter for dynamic PS.

Please can we see some high ISO comparisons? Like ISO 6400 or 12K?
PS: The chewed gum.... is disgusting. Please don't make a habit of photographing it.

In reply to:

eastwestphoto: is this good for astro-photography?

Probably, though only 4 exposures.
Pentax also has astrotracer, it tracks the night sky for milky way shots, using its GPS and SR mechanisms. I doubt that we'll be able to combine these 2 modes though... at least not yet.

In reply to:

miles green: While i never found a good use for PS at high ISO (since it requires a tripod), dynamic PS might be useful for high ISO handheld night scenes.

For example, photographing a church interior with dynamic PS, I imagine i would gain 4-5 stops from SR, shooting at 1/2 second, plus I'd take 4 exposures using dynamic PS to get an additional gain or 1 to 2 stops of DR as well as ISO, with the added benefit of additional resolution (though no moire benefit). Potentially, these could sum up to a 5-7 stop advantage over a non-stabilized system! So travel photography: forget the tripod! :)

I'll be upgrading my K-1 in the summer, and i'll be posting some tests on the Pentax forum.

I've had the K-1 since its launch. Pixel shift can provide spectacular results, not only for resolution, but also for DR and lack of moire artifacts. Processing has also been improved with the new versions of DCU. I'm not saying i enjoy using DCU, but it delivers when i need it, for PS.

I too am stumped for a good reason to use high ISO and pixel shift. Save maybe some astro application, but i'm pretty sure my PS images are all at base ISO.

Dynamic PS might change this however, I can imagine many applications where I can use high ISO, particularly night scenes, building interiors etc, when a tripod is not available. It would be excellent for travel photography (The K-1 is an excellent travel camera imho, if you can deal with the size).

On article Buying Guide: The best cameras for landscapes (180 comments in total)

The K1ii is out, so the K-1 can be had for even less! Improvements affect ISO, AF and PS.

Many listed this in the cons of the K-1: can't use pixel-shift without a tripod. So Pentax delivered, with in-camera image stacking. Not quite pixel-shift, but at least i don't have to go home to process.. If one does not need the extra detail, don't bother, just shoot normally. Or shoot in PS mode and if you don't like the outcome (too many artifacts) keep and process the first RAW and discard the other three.

What I'm looking forward to reading about is the AF test, as the K-1ii has increased processing power (new co-processor) and new AF algorithms, Apparently, it's much better than before, to the point of being competitive with other similar cameras (i.e. not a 14 fps sports beast).

In reply to:

MrBrightSide: In the days of medium and large format, photographers would routinely take black and white Polaroids to judge whether the image had enough contrasting tonal values and a robust composition.
So really, we should all be shooting black and white not as an alternative to color but as a necessary first step for any and every picture. If your scene doesn't have strong elements when viewed in black and white, shooting in color is not going to make it any better.

Indeed, i often shoot with the camera in b&w mode, so i get a b&w preview. And keep the full-color raw. Back in the day, fitting a yellow filter also helped with viewing, and contrast of course.

Charlie Jin: Suddenly, the pictures from Leica camera look much better~! They have more distictive Leica-characteristics.

I think that most of us reading Leica news comments are here for some jokes and light trolling.... Real Leica connoisseurs are running back to the boutique to return their new Leicas, just so they can buy them again in a month, at a higher price...

cricnours: It's too much !! I have to stop that red dot addiction !!!

... but when I see how much money I spare using my asian gear... I will continue painting a red dot on my Zony/Panolym/Fujikon

;-)

Why?
Leica fans need to pay an extra 4 grand to get rid of the red dot!

On article Sigma interview: 'This is just the beginning' (339 comments in total)
In reply to:

miles green: Reading this interview, I'm seeing that new top of the line Sigma lenses are non-stabilized dslr lenses. Yet, they do not release these lenses for Pentax K mount, which is the only DSLR with in-body stabilization, and in addition feature pixel-shift technology. As he points out, a stabilized lens compromizes size, the design and size of the focusing elements, and eventually IQ. So Sigma's top-shelf lenses are ideally suited for Pentax.

Pentax on the other hand is busy re-badging stabilized lenses from Tamron (15-30 and 24-70), giving up the advantages of having IBIS when it comes to lens design.

Can't these 2 companies just get along please?

I know Pentax's market share is small, but the KAF4 mount no longer requires manual aperture coupling, so it shouldn't be that hard to manufacture. The technologies are already there on both sides, just the hand-shake is missing. An excellent collaboration could be born:

Sigma finds a new market for its lenses, with minimal effort. (No re-design from scratch due to completely different flange distance). A market that makes the most of its VR-less high resolution designs. This is achieved with minimal effort and no issues infringing on VR patents.

Pentax finds the capabilities it obviously lacks to design and manufacture a system of lenses for its cameras...
