Sunshine4784: Well, truth be told, Pentax is not that third party friendly. Right now, there's an issue that few sigma lenses are not compatible with K-1 which creates scratches. Base on their interview, Pentax didn't even let other companies about their new camera and K mount informations to support more lenses.

Meanwhile Canon and Nikon designers are kicking themselves thinking "why didn't we think of sabotaging Sigma like that before Pentax!? Why do they always find the clever solutions? I mean look at that lens-changing spotlight"

Pentax certainly isn't upset because you can't buy a Sigma lens rather than a Pentax one. Canikon wish Sigma would do the same for them.

Afaik, Sigma won a lawsuit in the 70ies or 80ies against the big camera manufacturers (then Pentax, Canon, Nikon in that order) allowing them to use their proprietary lens mount. Since then, it's been hostile... Sigma still reverse-engineers all of their mounts. They have their USB dock to they can easily reprogram their lenses in case the new cameras don't recognize them anymore. I believe i read the Nikon D5 is one of those cameras?

cirtapfotos: The Winner...Again Nikon D810 at 64 ISO can't be beat.

So lets compare the best case scenario: D810 at ISO 64 vs K-1 at ISO 100 with pixel shift.
You want to try without a tripod? How about 5-axis IBIS worth 5 stops for all your primes?

marcio_napoli: K-1's PS is just like 36mp Foveon IQ.

If Pentax PS tech has proved one thing, is how people really want Foveon sensors but haven't yet realized that (according to how many comments we have here about PS).

Because Sigma is well... Sigma. How many people do you know that ever got educated about Foveon IQ and Sigma cameras in general?

But maybe now the community will get more aware / educated about how mushy these bayer sensors really are.

except it can do high ISO or shadow recovery 2 stops better than bayer without PS. Foveon can do it on a moving subject and handheld - just don't let the ISO go up. I shoot Pentax. I'd want a Sigma ifi was a strobist.

GarysInSoCal: Impressive camera Pentax... but PLEASE show me a list of lenses for the K1 that I can afford... cause as of right now... I haven't spotted a quality zoom lens for this camera for less than $1600. Without a decent selection of affordable optics, this camera will go down in flames, regardless of it's technological advances.

The 28-105 is very tempting as a travel and landscape lens, it's small, sharp all the way to the corners and weather-sealed. And relatively cheap.

GreatOceanSoftware: 10 years from now: "Remember the days when we used to mechanically shift the sensor? Ha! Why didn't we just spend our energy developing the cuz (probably quantum dot or some such) sensor?"

You mean the Foveon / Sigma sensor?

About the Pentax 77mm f/1.8: i just tested it on the K-1 and as expected from a portrait lens, it does not have a flat focus plane, but rather a parabolic one, curving towards the camera towards the edges of the image, especially at close focus distances. It's not a bad lens, quite the contrary. It's just not a macro lens.

Mikael Risedal: take away the color and look at the Pentax pixel shift result against the D810, no big difference in resolution
Its a color interpolations / estimations error who are seen most in d810, there are others raw converters who shows less color artefacts than Adobe and the same camera.
Get me a camera where the sensor out resolves the lens in one shot

Pentax Q....

In reply to:

Mister Joseph: What's the lens used on the K-1? Outside of the image center seems to be out of focus or just soft?

The 77 is a portrait lens. I doubt Pentax would give priority to a flat focus plane (i can check tomorrow). That's something one wants from a macro where reproduction is one of the applications its designed for. I think you should try the DFA 100 macro.

I have a pair of Elinchroms with sky-port, which are great. If i want to add a hotshoe flash, i just use an optical trigger. Of course you can't adjust the hotshoe flash remotely, but the biggest catch is its slow recycle time compared to the studio strobes.

Is the yellow shutter button somehow related to the well-known red dot?
I hope Pentax's green button doesn't cause any crazy coloured-dot-price-syndrome. ;)

(ok, ok, i'm just kidding, i'm jealous, and i even like the yellow dot)

ISO 3M is a marketing stunt and i don't think it's working.
Nikon's technitians on the other hand have upped the bar in the critical ISO area from ISO 6400 to 52K by about 1 stop (to my eye).

tom1234567: The Leica APO-Vario-Elmarit-SL 90-280mm F2.8-4 is set to cost £4650/$6395

I will order two right away???
were do they did up these prices from do they live in the real world?

@androole, that's exactly why they chose an unorthodox focal length, so you can't compare one-to-one, so they can charge pretty much anything. Still, a 70-200/2.8 with a 1.4x TC reaches 320/4, which is faster than 280/4. Also 70mm is not 90, but to put this in price-related perspective, one might compare with TWO 120-300/2.8 Sigmas...

mgblack74, with Pentax the combo you suggest would be almost half price of the single Leica lens.

This camera and lenses are designed huge and bulky and ridiculously expensive, so that the shooter can be seen and wow-ed from far away.

zakaria: I like the conceive and valued report except the conclusion!!!
K1 is not at league with d610 or 6d .both last camera are entry level cameras and outdated. You even didn't put it in d750 league.
The fair compare is D810 at least both are handling 36 mps sensor
Both are 1/ 8000 shutter speed both are well made bodies not a combination of plastic and ss. Don't forget the Pentax unique features that you already have mentioned.

Nomoreheroes, when you add wifi and gps to a camera, something has to be polycarbonate or you won't be able to connect to anything.

dosdan: Cary, I understand you only had a few hours to use the camera. But there's some nice features in Pentax cameras that make the shooter's life easier.

For example, in your "Pentax K-1 Pixel Shift Resolution demo" video, you zoomed in repeatedly to check the effect of the pixel-shifting. If this camera is like earlier Pentaxes, when the review image appears on the back LCD, you can just turn the rear dial (now used for zooming) 1 click to the right.

Rather than going 2x, 2.8x, 4x ... 16x to check the focus, you can preset the first-click amount. On my K-3, I've set it to 8.3x (100%). So I get a very convenient jump to 100% pixel-peeping for focusing accuracy. Once there, left-turning the dial zooms out (8x, 5.6x etc), while right-turning zooms in (11x, 16x), and pressing the OK button on the back returns you to 1x.

Your current zoom level & panning position (e.g. lower-right corner) holds as you use the front dial to move through reviewing shots.

All very sensible.


As dosdan pointed out, Pentaxes do this (toggle through pictures maintaining selected zoom) using the front dial.
