Pentax launches industry-leading tele lens

Well, the headline is true, but it is for a 12-660mm CCTV lens :ugh:

It is for the PENTAX PAIR 02 ZOOM LENS MODEL H55ZAME-F-PR02 - 1/2-Inch Format 55X Power Zoom Lens f=12mm~660mm(~1680mm with Built-in 2.5x Extender)F4.0 -> PENTAX Introduces Next-Generation PAIR Technology - Technology | Centre Daily Times - State College, PA | Penn State, Nittany Lions, weather, news, jobs, homes, apartments, real estate


The interesting thing is their "Pentax Atmospheric Interference Reduction" (PAIR) technology:
QuoteQuote:
Building on the first-generation PAIR 01, winner of the 2010 ISC West “Best in Video Device” award, the new PAIR 02 adds an industry-first Heat Haze Reduction function.
I recently wrote about the problems of atmospheric turbulence for tele photography in my blog: Falk Lumo: LumoLabs: HowTo long range telephoto shots

It would be amazing if this technology can be brought to 35mm lenses. All of a sudden, Pentax could leapfrog from last to first in the tele realm

Video of PAIR 1

Well, I found the following video demonstrating the previous PAIR 1 lenses. The turbulence is still visible (not reduced). So, what I see are some of the methods I described in my blog. Not sure how much this helps in still photography where you have RAW file treatment.

Nevertheless, the video is rather impressive. And it is previous generation only

Amazing indeed, Falk. Both the video and the leapfroggery.

I'm used to seeing "Pentax" and "leapfrog" in the same sentence, but not one in which Pentax is the subject rather than the object. (continuing the grammatical references ...)

Wouldn't that be a hoot if Pentax released a CS mount EVIL camera promising to be compatible with it's previous cctv lenses?

One obvious application is surveillance, both civil and military.

The question is though can this technology have a spinoff effect in dSLRs

That was the question I asked. Much of what was shown can be achieved with RAW converters. Some would require stacking which RAW converters (unlike Sony NEX cameras) don't offer out of the box.

Most difficult is the effect of dealing with atmospheric turbulence though. Maybe, PAIR2 brings progress in this domain. Turbulence destroys image quality with long exposures and physically wide apertures. You see it in the movie above where the Japanese letter subject "floats" as if seen through a swimming pool water surface. Progress here could be interesting (as is available in astronomy). That could apply to dSLRs too. However, I don't know what PAIR2 brings in that department.

Unfortunately, CS mount lenses are meant for 1 to 2 Mpixel images. So, it may not be the best of all ideas to make a CS mount EVIL still camera

So for now we have to deal with ground heat turbulence the old-fashioned way, like Astronomers do: Shooting only objects within 30 degrees of the zenith

Using Adaptive Optics isn't what I would call old-fashioned. You must really be at the bleeding edge of things

Ugh... the thread should start out with the text "hahaha... made-jya look! "

The "Power Zoom" lives on! I wonder if that 2.5x TC will work with SDM. <lest anyone get carried away, I kid>

Most telescopes don't have adaptive optics. They're like the Full Frame of telescopes
