K1ii's "Dynamic Pixel Shift" Will Put A Premium On Small High-Quality Lenses

.
To me, the most exciting new feature of the K1ii camera is "Dynamic Pixel Shift" (DPS). If it works as well as I anticipate, I believe that it will place a premium on smallish high-quality K-mount lenses.

Why? Because we'll be using the K1ii "handheld" when in the DPS mode, which will encourage the use of lighter-weight lenses. And to wring every bit of goodness out of the DPS mode, we'll want to use high-quality lenses.

I like to shoot fast prime lenses (especially adapted Zeiss and Leica R lenses). My Zeiss lenses are heavier than my Leica R's, so I expect when my future K1ii is in the DPS mode I'll tend to use my lighter weight Leica R lenses more than my heavier Zeiss lenses.

Other lenses that I think are likely to excel in the DPS mode include: The Pentax 3-Amigos (31mm, 43mm, and 77mm), and Pentax's better macro lenses.

What other lightweight premium-quality lenses do you think will become popular in the DPS mode on the upcoming Pentax K1ii camera?

There'd be Voigtlanders that would benefit, too.

That's an interesting thought. It comes down to what gives you better IQ:
a) A large, highly corrected lens with its handshake blur due to its big size (and therefore no PS),
or b) Smaller lens, which allows optimal use of handheld PS

Maybe DA 40mm XS will become the new best performer

I stuck a Pentax-A 35mm f/2.8 on the K-1 today. Just because. The K-1 looks like it is missing something the lens is so tiny. How did we get from the size of the 'A' lenses to something like the coming DFA 50?

A refresh of the FA Limiteds would be welcomed. I agree they are a perfect match to the K-1.

I wonder how many FA Limiteds they built in the last batch?

I don't think you will get away with old glass/ small lenses for getting superb results just because of DPS.
Some objects move, and modern AF, and waerthsealing are part of the equation. But, yout idea requires testing.

Well. Sigma Art 35/1.4 and 100mm WR Macro are my kit for sure. Wide angle options are a bit mess, maybe 15-30 WR, maybe 15mm Irix and 25mm Zeiss.

Fuh, the DA 35 f2.4 is quite sharp, and definitely light and small. I don't know great its performance is at the edges on full frame but at center it's almost painfully sharp on crop. And I would imagine it's quite fast focusing on the K-1.

Why would DPS encourage light weight lenses?

Lighter camera/lens assembly is easier to hold steady for a lot of people.

FA20, FA31, FA43, DA*55, FA77, DFA100WR: I reckon I'll be OK. I don't think the FA*24, Sigma 35 Art or even the FA*85 will be a problem either.

A small, flare resistant prime in the 15-18mm range would be perfect. A slower maximum aperture would be just fine.

Inertia (which in turn is caused by mass) actually helps the other way round.

...unless the combination of your muscles (springs) and the mass form a resonant system.

I think physiology might play just as important a role as physics in this instance. Your muscles don't lock like mechanical linkages, so any parts in tension will be vulnerable to movement. You have to expend energy just to keep something still in your grasp. Lightness assists in reducing energy use, which helps minimise involuntary movements. Of course, if you can keep your camera support limbs in compression (eg elbows resting on a firm surface, and forearms triangulated to support the camera) that's ideal. The situation doesn't always lend itself to that, though.

Autofocus... I think is the answer to that.
