The Q firmware 1.12 has the fast AF of the 1.11, maybe even faster!!! They've also found the bugs this time: my Q seems stable and responsive again. Thanks Pentax!
JJack: Sigma mount is supposed to be more-or-less compatible with Pentax K-mount, right?
So will this lens work with K-5 and K30?
The same question about 120-300mm F2.8 as well.
The mount is the same, mechanically, though a little rotated. The flange distance is different, so Pentax lens won't focus at infinity on Sigma cameras. The electronics and levers are different, the Pentax aperture lever in partucular prevents its mounting on Sigma cameras....
In summary, only the rear lens cap is interchangeable!
Sorry, nice try, i wish it wasn't like that: I'd get a Sigma body in a flash! :)
Martin Datzinger: So. This, on a D7100 set to ISO 100, would very much do the same as a 27-53/2.8 lens would do on a D600 set to ISO 240 (or thereabouts). Except that only very few people would buy such a lens for their D600 because of the very limited zoom range and there is no chance of getting the same DR on the D7100 as with the D600 set to ISO 100 (whilst noise just evens out at higher sensitivity settings). And the viewfinder is smaller with an even worse representation of DoF.
Then there is the question of pricing: D600 + AF-S Nikkor 24-70/2.8 = €1500 + €1540 = about €3000D7100 + Sigma = €1220 + (certainly) more than €1800 = (certainly) more than €3000
Let alone the worse resale value of the Sigma as compared to the Nikkor.
So I have to ask - why not make it a 16-50/2.0 lens in the first place? Close enough to equivalence, about the same weight and price, a lot more usable and still totally unique in APS-C land.
At ceaiu:At 2000$, it would be 3.5 times cheaper than both the most expensive aps-c lens (the Pentax 560mm f/5.6) and the most expensive m4/3 lens (the Olympus 300mm f/2.8). Both are priced at 7000 usd... Not that this means anything.
This obviously expensive lens would be especially attractive for systems that don't have FF cameras, namely Sigma and Pentax! In Canon and Nikon mount, I'd much rather get a FF body instead. But since i shoot Pentax, i'd be interested in this lens, if it were available in Pentax mount.
miles green: It's a pity the Sigma SD1 is not on the comparison tool. At base iso, it's phenomenal! Incredible clarity and no moire!
The Leica M9 still has a bayer matrix... Gotta see it to believe it! (just make sure you look at the center of the frame, where the lens can keep up!)

Mannypr: I know that. the main topic is the effects of no anti aliasing filter on high MP camera but what is surprising is the small amount who have commented on the rather obvious and surprising superiority of the pentax over all the others on all test modes . On the nikons I can see a difference between them but I admit they are small , even at 100%
@HowaboutRAWComparing the D7100 and K5iis at iso 6400 on this site, the K5iis looks well ahead (much cleaner) to my eyes.
Regarding AA-less cameras, I apreciate the increase of detail visible on large prints at at high screen manifications, but there is also a fair amount of false detail (moire banding) that is visible even at normal viewing.... I don't like it, so I'm not persuaded! AA-less sensors seem to work better the higher the resolution of the camera.
At the end of the resolution race, we'll all be using prime lens at f/5.6 or f/8....
Mister J: Love the shades (think iPod) but for serious snappers, it has to be black
I think they only paint them on the outside... ;)
drummercam: Simple math: Any marketing that enhances revenue flow increases the chance of a K-5 replacement. I have to assume that everyone laughing at the K-30 colors are fanboys for other brands who want Pentax to fail. I had the same impression in discussion of the K-01. Makes no sense to me to diss a brand you want to use.
My opinion is that the K-5's are simply a very hard act to follow. For it's entire run, almost nothing else has been near it for price, performance, IQ, and WR. Ergonomics and interface are great -- they could put the upgrade into the same form factor and it would be fine with me. If Pentax takes it's time to replace the K-5's and get it right, it's fine with me.
As for colors, the "K-3" photo that circulated about a year ago was a K-5 Special Edition (re-shaped grip) in what now seems to be called silky silver. I thought it looked totally boss. If the new flagship looks like that or in black/silver it will fly off the shelves.
The Special Edition K5 was silver, had a beefier and more sculped grip and a crystal scratch-proof screen. That's me holding one with a limited edition 21! :)
edit: oops, drummercam beat me to it!
DotCom Editor: I'm confident that this will make me a much better photographer and increase my sales. In fact, it was just a few short weeks ago when a couple, searching for a wedding photographer, came to me and asked, "Are your cameras black or Silky Bordeaux?" If only I knew then what I know now...
@ DotCom Editor: Does a red or blue car make you a better driver than a black car? I don't think so. But fortunately, not all cars are black.
Beautiful work, i love the pictures!
Why so many nay-sayers!? A few scuba tanks and a rebreather might have made it easier.
Ασε... δεν το σχολιαζω, με πιανει κατάθλυψη...... Δυνατή φωτο!
Cane: It says in the spec it's for Pentax K, yet in the story it isn't. Which is it?
I hope they make it in Pentax mount... It was on the top of my list. :(
By the way, i really don't understand why this company can't get its own name right... I do love my Samyang / Bower / Rokinon fisheye though!
Aaaaah! Nooooo! And Pentax too please! Maybe Samyang will do it...
Excellent, and very cool. Some needs to strap a gopro on a RC chopper! :)
Congrats Mahesh! :)
Mescalamba: Why would anyone buy this?
AngryCorgy, the K-01 is selling like crazy. I think all the regulars from the US on the Pentax DSLR forum have one by now - check out the poll thread: 50 some and counting. Prices are still high in Europe, so i'm waiting.
I don't see the lack of evf or hotshoe as a big drawback for the MX1: i'd want this for practial reasons: a zoom that fits in a pocket and looks decent if it's hanging from my neck. If i wanted to get technical, i'd much rather use my K5.
i like your sweeping second!
