HowaboutRAW: So where's the Sigma Quattro SD and SD-H announcement?

Two new Foveon mirrorless cameras from Sigma, one with a new APSC-H sensor:

This is definitely the weirdest ILC I have ever seen. However I like the APSH sensor, I thought is was forgotten since Canon abandoned it.

Nice, I especially like the wideangle compact, which is unique and ideal for hiking, but in my opinion a 650/850 USD enthusiast camera definitely should have a built-in EVF.
When Nikon was able to introduce 3 similar cameras at once, I see no reason why Nikon didn´t add another version(s) with EVF built-in. Apart from missing EVF everything else looks promising (lens range and speed, AF speed, external controls, touch screen etc.).

The Sigma 50-100 is great; unrivalled and unique. The luminosity diffenrece compared to usual fast telezooms with f2,8 is huge, 1,3 EV is hell of a difference.
However having used the 18-35/1,8 for almost 2 years I think f1,8 is maybe too fast, making the lens too big and heavy (and my Sigma is "only" 810g, while this new one is whopping 1490g). It could have been a bit slower, e.g. f2,2 or f2,4 (and still have the advantage over usual f2,8 zooms), wchich would make the lens either smaller and lighter, or rataining the same size it could have bigger focl range.
I love my 18-35, but I wish many times it was smaller/lighter, or with longer reach (basically something like 18-35 f2,4 with cca. 500g, or 16-40 f2,4). The same with this new one: either lighter 50-100/2,2, or longer 50-150/2,4.
Daydreaming, I know. ;-)

Johannes Zander: I want the Sigma 50-100mm F1.8 in m43 mount. Will that happen?

It wont happen. First this is a different construction made for DSLRs (different flange distance, so it would need a redesign for mirrorless). Also there is the size and weight issue, which is not a problem per se, but I somehow cannot imagine a small M4/3 camera with this Behemoth attached.

wed7: No K-mount for the 50-100, ouch!

But with the 18-35mm Sigma announced Pentax mount right from the start, even though it became available a lot later. Now there is no mention of Pentax, so I am afraid no Pentax version this time. :-(

I wonder why. The 18-35 is available for K-mount and pretty popular among Pentaxians (I have it to), so why not this one?

In reply to:

daddyo: I really look forward to seeing some test shots from someone who uses this lens properly. The bulk of these samples are worthless. Why would you do shot after shot of some distant landscape, buildings, etc., I assume hand held, at 400mm. The atmospheric distortion in those situations says absolutely nothing about the optical quality of this lens.

Why do you expect a normal photographer would shoot at 1/800s or faster? The whole point of stabilized telephoto lens is to be able to shoot at longer shutter speeds. What´s this lens´OIS benefit, 3, 4 EV? And 1/400s is only 1 EV below the advised shutter speed for non-stabilized lens.
So I think it is completely OK that DPR shot at 1/400 or longer, because that is how this lens will be shot at most. While I understand the call for those perfect shots (tripod, cable trigger etc.), most of the shots should be shot the way the majority of users will use them.

Maybe it´s the lens, maybe the atmospheric influence (haze), but the pics do not look good. Contrast, colours, sharpness, everything is mediocre. I had a telezoom once that gave pictures like this and therefore I sold it. But that was a 300 EUR zoom, not expensive Leica lens like this. But it´s maybe too early to write the lens of; let´s wait for nicer weather and full review.

Seahbc: Maybe the 85mm will morph into a Pentax DFA 85. :p

adbluesky: you may be right. I don´t have the 77mm, but on pentaxforums they swear it is a stellar lens (Limited). Of course 36 Mpx is a challenge for any lens so I can imagine that once stellar lens may be not that great on K-1.
Anyhow the 77/1,8 is still here, so the 85mm is not inevitable; however there are lenses that are needed much more, especially wideangle primes (31mm is the widest available for FF).

Andrew Elliott: If only Pentax would release lenses very very similar to these.

As a typical Pentaxian I have never shot a video with my K-5 IIs. Video in a DSLR iis a useless feature for me. ;-)

Not impossible, however with the FA 77mm f1,8 I don´t think there is a need for another f1,8 portrait prime. An f1,4 lens would be more interesting.

dansclic: I understand how emotion CAN drive a buy option for pentax. But from a certain price tag, émotion makes room for réflexion and reflexion leads people to more established lines which have an enormous Lens program. As you said, buying thé 15-30 and 70-200 make à lot of money ! They should have proposed a 28 mm, 35 mm and a basic 85 and maybe 70-200 f4. This basic equipment could meet more customers.....

I don´t understand the cry at lens prices. Are Canon/nikon f2,8 zooms cheaper? No, they are even more expensive. So basically at Pentax you get similarly priced (or a bit cheaper) lenses and a much cheaper body.
However I agree there is a lot Ricoh has to do as regards new lenses.

Anastigmat: Why now? The reason is that the world is moving to full frame, and it is do or die time for the Pentax brand. The APS-C market is saturated and users are reluctant to upgrade again to another APS-C model with practically no improvement in image quality. Medium format is nice, but it is a huge leap in price. There has to be an alternative to the APS-C or medium format strategy Pentax has been using.

The top of the line Pentax APSC models were being undercut in price by Nikon, so that it is no longer profitable. Turn about is fair play. Pentax is now undercutting the D810 in price. Since the sensor is the most expensive component in a FF camera, Pentax's pricing strategy on the K-1 shows us Nikon has been making $1,000 above and beyond what is fair on the D810. It is pure gravy. The artificially high prices Canon and Nikon have been setting on FF models is one reason the world has not moved faster to FF. Ricoh will change that with the Pentax K-1. Full speed ahead towards FF.

I completely agree. The market is moving towards bigger sensors, whether it´s enthusiast compacts segment or prosumer or pro ILCs. 1/2,3" sensor cameras have almost been eaten by smartphones by now, 1/1,7" sensor compacts are being replaced by 1" cameras, APSC DSLRs are being eaten by mirrorless so FF is the way to go for DSLRs. K-1 might be Pentax´s saviour.

Nica article Barney, thanks for digging that deep in history.
However I am not that sceptical about lenses: there are 12 modern FF lenses now and according to Ricoh the majority of DA primes cover FF (even in your preview there was a shot with DA 70mm wide open and seemed perfetly OK). So we have approximately 20 new lenses right from the start of FF. What other camera introducing new system in the last years can say the same? And of course there are more to come. I know there are many Pentaxians that have legacy Pentax glass but I do net expect them to be used for serious work, more for fun and there the potential flaws don´t matter that much.
Btw. where is the new roadmap? It should have been introduced along with the K-1. Have you heard something about it from Ricoh representatives?

ARTASHES: "The K-1 becomes the first conventional DSLR to offer a stabilized full-frame sensor."
Sony disagrees

a99 is not a conventional DSLR.
EDIT: I take it back, I forgot about the A900 (just like many have forgotten too).

tassosDA: Sooo,no smart comments about Pentax LED's this time? Anybody?? :-)

At K-S1 it was just a gimmick with no real meaning,however at K-1 it actually has a function. Actually after seeing the LED above the mount I wonder how come noone has made it before. I often had problems mounting a lens when switching lenses at night and this little light coud help.

h2k: "At the time of launch, Ricoh offers approximately 12 FA and DFA full-frame lenses."

Wondering what's the difference.

@MikeF4Black: there are 12 fullframe lenses in production, the majority of APSC primes is usable on FF (some "fully usable", some "when stopped down", however there is a picture taken with "must be stopped down" lens wide open and it´s perfectly OK). Add number of discontinued FF lenses, third party lenses and you have a nice portfolio right from the beginning. Incomparable to the a7.

In reply to:

davidbea: By the chart it indicates I can use my 35mm f2.8 Macro stopped down. I assume that means wide open I would experience vignetting. Anybody have a sense of how much and what aperture would be required to eliminate it? Also how much could Photoshop save/correct?
I very tempted except for the size which is why I have been checking out the Sony A7II and Sony A7RII.
Thanks.
David

Btw. the K-1 gallery has a picture shot with DA 70mm lens wide open and it looks completely OK to me. I guess most of the "need to be stopped down" lenses will only show some vignetting that can be solved in PP.
Plus I have seen a video where a guy used a DA zoom and while there was a black circle at wide end, it disappeared with zooming.
And if there is no full FF coverage, it doesn´t mean that you cannot gain more than a APSC crop. So maybe a 21mm DA lens does not cover full 21mm, but it can cover more then just simple crop (31,5mm), say 26mm eq. So it can still be useful.

veritalens: Question! I have never used any Ricoh/Pentax cameras (although I would like a GRII), is the pixel-shift procedure output comparable to Sigma's Foveon tech? Is the output similar?

And the pixel shift work at every ISO (unlike Foveon sensor that is usable to cca. ISO 400-800 only).

In reply to:

ttran88: I have to wonder, Pentax releases the K1 and gets all sorts of kudos from different brands of shooters. But with Canon's recent releases it gets bashed left and right. Are people just against Canon as a brand? Or are the recent releases not very exciting?

No fight, it just looked like there are no novelties on the K-1. The fps, sync speed etc. are mediocre, but similar to the competition. D810 has 5 fps (not much of a difference), same has the 5Ds. Sync speed: 5Ds has the same 1/200s, D810 slightly better 1/250s. Only the AF modul is questionable: 33 points is behind the competition and I am afraid we cannot expect Canon AF speed. But I will save the judgement for later.
