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.

Is it completly random or it's pixel dependent?  What I mean.  If you shoot with your caps on twice.  With the same exposure time and same iso.  Will both raw look exactly the same when push 4 stops?

Neither - It's not fixed, the results change from shot to shot. It's also not random, the readout electronics Canon uses tend to introduce patterns into the noise. You have areas with higher noise next to patches with a cleaner signal.
Now fixed pixels could easily suppressed, and completely random noise can be cleaned up by statistical means or simply left in as it has a mostly local effect.
The patterns OTOH are bad because they remain perceivable even with aggressive noise reduction or image size reduction and introduce large scale artifacts.

EOS Bodies / Re: do you hope for sony sensors in the 5D MK 4?

There are other players, but not necessarily in the digital photography space.

We also have STM, building for example  the sensor for the Leica 240. At the first glance that's not much, but this impression is misleading - the usage of smaller structures left them with at least as much currently mothballed producion capacity, both for large area/small structure lithography and 300mm wafers, as canon has in total. Order in sufficient quantity and I'm sure they'll open one or more lines. Anything less the active 300mm line can handle.
That company isn't a big blip on the radar for DSCs, but they have tons of experience making stuff others find challenging or impossible, and doing it on a large scale. Coincidently multispectral imaging sensors for military usage, something that requires ideas that mirror those foveon-like patents from a while ago.

quite the typical reaction for people who can't deal with the garden path challenge ;)

If your goal in posting here is to intentionally trick people, that says something about your character. 

Wouldn't a neuroantomist know that the garden path has the simple purpose of estimating a persons mental work set, it's part of the required curriculum after all? Which in turn leads to obvious implications.
As a reminder: this challenge doesn't trick people who approach a problem with either an open mind or the capacity to reflect on a perceived contradiction and take their preconception into account.

The language I use tends to be very precise

I'm sure you believe that's the case.  Metacognition is not everyone's strong suit.
That's why I have others, not involved, but quite often bemused by the reactions, check that from time to time and get independent confirmation.
NB: quite the typical reaction for people who can't deal with the garden path challenge ;)

More properly ambiguous language on your part...if you're trying to say something, don't bury it in innuendo. 
The language I use tends to be very precise  - precise enough to find out whether the other person actually reads or just looks at a few words and fills in the blanks. The latter case offers additional insights, of course.

Or perhaps I'm unaware another manufacturer delivering PDAF on the image sensor where 16 million pixels (80% of the total MP) are used for AF. 
Apart from being wrong, as anyone who knows how PDAF works realizes, that numbers game doesn't matter. Its about the functionality provided - is the PDAF grid dense enough to track a subject?

DPAF is disabled at one of the many possible resolution/frame rate combinations, but works at all of the others.
"One" is not the exact number...

That's 'hamstrung'? 
Yes, considering its symptomatic

The new Samsung NX-1 delivers 15 fps...but at anything above single shot frame rate, it drops from 14-bit to 12-bit RAW.  Does that mean continuous shooting on the NX1 has a value of...zero?
That depends on whether a picture with the tonality and luma resolution of the 5D3 offers at base ISO has a value of zero. Again - function over spec sheets.

Much like your flawed understanding of the use of non-electronic ballasts in lighting, your views are apparently at odds with reality.
Reality: Operating a lighting system that the 7D2 could compensate for would get you a fine or some time behind bars - violation of the equivalent to workplace security and similar regulations plus the intrinsic properties of common utility AC motors - in just about any country I've worked in. Across five continents that sums up.

On the other hand just look what that self imposed lock in did with DPAF. What could be top of the line is hamstringend by legacy decisions while others deliver what DPAF should have brought.

So improvements delivered by others are more important than DPAF to you
That conclusion implies a lack of comprehensive reading skills...so much for a clear mind.
It's not a matter of importance, but little details like having to disable the feature in certain video modes.
The feature would have an invariant value if the sensor could be read fast enough. Mandatory disabled due to a design flaw it has a value of...zero.

If Canon used Sony sensors, it reduces Sony's incentive to innovate. You'd have Sony, Canon and Nikon all using the same sensors. You want to talk about a company riding sensor technology for as along as it can? That's exactly what such a non-competitive scenario would encourage!

You're missing the other sensor manufactors in that equation - its not a Sony/Canon duopoly, there are quite a few other players in the game.

EOS Bodies / Re: Canon 7D Mark II - DXOMark Review
« on: November 06, 2014, 01:58:54 AM »

The last time I saw some was yesterday.

The ballasts where I work were installed in 1978.

Considering the savings in operational costs thats throwing money out of the window for no good reason. From a business perspective that in itself raises red flags.

It takes a long time to cycle out all the old units....
Sure, but the last time I've seen flickering discharge lamps in a high school gym was about a decade ago, and the serious venues where faster to adapt.
Quote
BTW, the electronic ballasts are generally about 20 to 30 percent more efficient and usually run at 20 KHz... there is still flicker, but you would need a shutter speed of 1/50000 to catch it... something that the 7D2 "just ain't a gonna do"
Even at 1/50k you wouldn't see much, during that time frame you retain enough residual emission to cover the gap. The DSCs couldn't see it, but the high speed video cams would. 8)

Oh, wait...there are.  ::)

Considering that old ballasts sold for scrap net more money for the copper in them then new electronic ones cost...guess I'm more drawn to the rational.

  And there only 2 ways for a "decent photog" to counter flickering lighting:


Which makes me wonder: where does one still find flickering lighting?
If I'd intentionally tried to buy something with an conventional ballast I'd have real trouble finding one. And venues that haven't updated their lights? About just as rare, as it's a quite expensive idea not to do so.

EOS Bodies / Re: Canon 7Dii vs Nikon D750 Dynamic Range Test
« on: November 05, 2014, 04:17:31 PM »

I appreciate the comments and feedback.

As a secondary observation: Watching not only for the borders between steps, but even on clearly delineated steps for color uniformity is interesting - if it gets too colorful here on should netter expect either a similar effect or heavyhanded noise reduction on areas in the same zone of production pictures.

EOS Bodies / Re: Canon to Continue Using Canon Sensors in DSLRs

Now find me a single (pretty much) high school sports shooter who has a Nikon, sure there will be some, but a huge majority f them will be buying Canons, it depends  where you look to see these moves.

Look in the segements that can afford to change or keep additional systems w/o taking a mortgage - that demography is moving. Just talk with the folks at rental houses - for example despite higher numbers of AirTTL-Ns in the inventory as a Nikon user you might end up involuntarily using the standard remote; no such concerns w. Canon
Thats the dangerous part with sales figures, even if you get reliable ones - a single number to describe a complex situation, the same as with DXO's rating system.

The best thing for consumers is for Canon to get off their lazy asses and COMPETE, in every aspect, in the sensor marketplace. :P

Either that, or taking the third option and source the sensors from one of the other manufactors - for example the STM one in the current Leica at least matches its Sony counterpart and considering STM's production capacity...
