I'm not sure how the Sigma compares to the Nikon 24-120mm, then it's 15mm shorter & suffers from Sigma's reputation for having AF problems, so I wouldn't be surprised if the Sigma w/ F mount didn't sell well either.

The Nikkor was designed with the idea of correcting CA in software in mind. If one accepts this it's about on par with the Sigma or the Canon 24-105. The same situation as with the Canon - no great benefits, but also no first party service and you lose one lens that counts against the requirements for CPS/NPS.

As far as I know, Canon is the leading camera maker in the world, so they are doing something right.
That path of thinking can go horribly wrong - on the more graceful side GM's/big 3's market share hasn't recovered 40 years after relying on the trope, and how well Nokia handled similar disruptive changes in technology is in recent memory.

However, the dual pixel sensor technology is way ahead of everyone else, and gives Canon a big advantage in the video market and will serve them well when they do produce a viable mirrorless product.
What are the practical implications of DPAF in comparison to the PDAF the others use? First you trade an already dense grid of cross type sensor points for a slightly denser array of linear type points. Second you need separate readouts for AF and image generation(otherwise you could use AF while recording HD60p video or during LV sequences). The latter part in it's full severity is a consequence of Canons readout pipeline, but you'd still feel some impact in any technology that uses also image data. Now what do you gain? The ability to track subjects that are only a few pixels across without relying on contrast and motion vectors. Yet you want those two data set for subject identification anyway, but preferable at the highest possible update frequency.

Umm...how, exactly, do you shoot video with an OVF?

The same way it has been done for decades - use the shutter disc as mirror.

I really want to see some raw statistics generated for the NX1. I am very curious to know what it's SNR and DR are at higher ISO. I think this could be a phenomenal camera for astrophotography (with the one major caveat that there really isn't any control software out there that will work with it...most of it is for Canon, some of the newer stuff supports Nikon now, as Nikon is starting to take the lower end astrophotography world by storm.)

In that context a little detail - the NX1 relies much less then most other cameras on application specific hardware, it's  more in line with Samsungs other consumer electronics products, quite programmable and general purpose. Remember the part of the presentation where they talk about what you can do with lots of full res frames, and how the camera being designed to be extendable. Basically the interviewer asked about why only jump/ball detection, with the answer going along the lines of "just load an app, no big deal".
There shouldn't be a fundamental problem in doing ML-like stuff with that camera. :)

Ach echt? Das interessiert mich. Nenn mir doch mal einige Internetdruckereien die auf große Farbräume setzen.
Oh really? I'm interested in stuff like that. Name some german printing sites which are using wide gamut colorspaces.

cyberlab.at uses a wide gamut chain and also supplies the proper color profiles for softproofing. In case the printers are to far away or it's about media types I don't want to handle myself.

Third Party Manufacturers / Re: LuLa likes the Samsung NX1

I always find it interesting that LuLa falls in love with each new camera model.
Reviewing only the cameras that they are already interested in would explain quite a lot in that regard.

Their review of the new Pentax MF camera has me wanting one :)
To sad it doesn't take the SK40-80LS ;)

I believe Canon owns the pro market, simply by observation. How many photos have you ever seen of sporting events, for the past decade (including recently) where any brand other than Canon utterly dominated? Canon owns the pro market.

Cavet emptor - sporting events aren't exactly the whole pro market. They're more the low investment/low income potential segment, the kind of assignment you'd get at a paper after mastering the press conference coverage.
Go into commercial or at least editorial photography and every member, including the gofers, of your crew outearns the average sports shooter by a good margin. Here Canon was dominant; today you have a good idea about who has long term sponsorship contract.

Hi,
   I thought Sony already had an 135mm STF lens which they inherit from Minolta, but in alpha mount and manual focus only.


They have - but with contrast AF the strict no AF limit is no more, as a native E-mount lens that idea would be in the realm of the possible. (And Sigma is less likely to release a counterpart, while something in the 135/2 or /1.8 range was talked about in the past. It would be right in line with their other primes at least. :))

39
That will be an exciting lens to use on the A7 series because it won't need an adapter and will likely have fast autofocus.

With the 135 I'd hope for an STF-version. That might not make it an AF-king, likely no luck with phase detection, but the rendering of OoF areas is rather unique.

But the 7d2 doesn't run ML, and you get get the 4k Panasonic GH4 for less money...
A w/o ML we're stuck with the reasons that made the raw output hack mandatory in the first place - with a devil in the details difference: back when the 5D2 came out there was not much to compare it against. Today you cut back and forth between footage from different cameras, making such details more apparent.
(Not to think about the additional implications of roll stabilization via sensor vs. post. Now considering a timeframe that encompasses typical write-offs or the last product cycles. )

10 FPS OVF cameras are vastly more complicated, difficult and expensive to produce than EVF mirror-less viewfinders. I'm not sure you appreciate the enormous technical challenge of building a 10FPS reflex system. These camera are engineering marvels and only a few companies in the world have the capability to build them.


One of the fundamental wisdoms of engineering:
A machine isn't perfect when you can't add anything else to it, but when you can't remove anything without the machine becoming unsuitable for it's intended purpose.

I know, Mr. Goldberg thinks otherwise, it's also incompatible with the philosophy in chindogu, but I see no intrinsic value in reducible or even redundant complexity.

42

Let you google that for me :-> ... I read in a smart book I purchased that 1/1 flash of a 580ex2 is 1/800s?
That would be t0.5; t0.1 for a full discharge is much longer.
On the upside thats only for a full discharge - at half power you can already use a quarter of the shutter speed and effectively have gained one stop. And get twice the battery life, half the recycle time, less heat for free.

43

ignoring mirrroless, sticking to old sensor technology.
only thing canon is improving on their sensors are video features (dual pixel) that i have no use for. while avoiding to do the next step and offer 4K.
And even that's quite smoke and mirrors - dual pixel sounds cool, but in which way is it better then everbody elses on sensor PDAF? Esp. considering that the old sensor tech prevents full readouts at a sufficient rate to make use of it's theoretical potential.

44
And I previously felt like the lack of 2.8 zooms was a huge downfall for Sony. Looks like those are coming soon as well.

Has this actually been stated anywhere?
They showed a 16-35/2.8II and 24-70/2.8II. Cavet emptor: They're A mount, whether they've got a motor&firmware that makes them play nicely with the A7II(A9?)'s native AF system remains to be seen.

Lighting / Re: R.I.P Metz Speedlites.
« on: November 20, 2014, 08:08:59 PM »

All demise reports on German online news only referred to them as a manufacturer of tv sets. Since Metz obviously didn't even manage to promote what they're manufacturing at all, the bankruptcy is no surprise :-\

They have a very specific target audience - people who expect, and are willing to pay for, services like planning, setup and after sales support. Basically the antithesis to the common online or mall customer. A bit like H,L&P1, but without the professional segment.
