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.

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...

Are these 100% crops or are they downsized?
It's exactly the "S"-size, for crops that would be quite a coincidence.
Well, the actual detail recorded makes that a moot point.

Why do you bring this up for studio portraits so much, since at least you can set your own lighting in that scenario.
Because of the other effects of the basic problem that causes the DR story. Remember that a Bayer-sensor has to derive color from a set of prefiltered luma values? Any noise automatically also causes color shifts; and the pattern noise those blotchy color patches. Now start with a sujet that has even tones thatare most suceptable to such problems and fine gradients that get killed by noise supression as a major trait - its easy to see why market shares shifted radically in recent times.

Third Party Manufacturers / Re: One Samsung Camera to Rule Them All
« on: November 03, 2014, 01:14:55 PM »

Your talking about the behavior of the human eye. That is external to the camera, and has nothing to do with ADDITIONAL lag imposed by the device.

Thats a misconception! While external its also influenced by the camera.
The behavior of you eyes changes with the luminous flux - once the EVF puts significantly more photons on your retina the lag caused by your eyes decreases compared to the OVF. For the lag between the world and your brain you need the sum of both viewfinder- and your own lag.

What you experience happens when the camera can't raise the sensitivity to a degree that allows for a proper exposure while retaining high frame rates an thus chooses to expose longer. But you couldn't shoot action under such circumstances anyway, at least w/o relying completely on flash.

I don't think you can have less lag than OVF...the lag in OVF is the response time of light itself moving through space. There is no digital processing involved at all...it's literally "real time". There is no lag imposed by the camera itself when using an OVF. 

There is the Pulfrich-effect - the same variable delay in your visual system thats behind this also affects you while using an OVF. The light hits your retina with a bit of delay, but the nerve impulse caused by it arrives earlier at your brain if the EVF provides you with a stronger stimulus then the OVF. When you have higher ISOs or dark lenses then the OVF takes the second place in that race.

Their EVF will REALLY have to PERFORM, and I'm rather skeptical that it will perform at a high enough level (low enough lag and no stutter)

5ms lag according to the specs, fits well with being able to process 240fps.
With a little detail for the low light shooters: system lag is the sum of lag in camera and the reponse time of the cone cells in the retina. The latter depends on the light intensity. Chances are that you end up with actually less lag then via OVF.

If Canon does not yet have this process for their big sensors (APS-C and FF) this will be the main reason.

Its not about the process per se, but a more fundamental matter; mainly limited bandwidth inherent to the design and all that entails.

the 7D2 dualpixel AF does not work with 60 FPS.

You noticed that as well?
It gives us an idea of why there is neither 4K or the "full readout&downsampling for more details & no moiree"-path.

I can't see it either because of Dual Pixel AF.


Only at the first glance!
Everybody else has phase detect on sensor as well. Some even cross types while taking more reading per second.
DPAF only gives you a benefit if the object is so narrow it would slip through those already very dense PDAF grids, but long enough to be properly identified. I.e. the tech is conceptionally interesting, but on the one hand not much of a practical advantage, on the other a liability due to the limited number of readout channels Canon uses.

EOS Bodies / Re: A Bit About the Modular DSLR Rumor

What will it deliver aside from market confusion?

Not much, it just means you're still stuck with the mirror, at the same time its an excuse not to commit to anything - you'll likely get the basic stuff twice but "advanced" features only in half the operation modes, or not at all.

Photography Technique / Re: how NOT to use studio lighting
« on: October 29, 2014, 12:54:18 AM »

What do you think, art, or ignorance?

The standard advice: use the histogram instead of a light meter. Paired with the joys of picture styles being applied instead of using actual sensor data and not using PP to get everything back on track.

Lenses / Re: More EF 100-400 f/4.5-5.6L IS II Talk [CR2]
« on: October 28, 2014, 02:35:25 PM »
Late fall is not the best time to start selling the lens, fair weather photographers like me won't use one until late next spring. 

In winter we have a nice temperate climate, 50-60°F in the lower regions is quite good for longer hiking tours. Also - esp. important with tele lenses - you get less heat shimmer. Saves you from reviews that blame the lens for the lack of understanding behind the camera. Perhaps less a problem for something in the 300-400 weight class, but for a standard amateur lens it would make sense.

If it could manage studio lights too (even just manual power) I'd buy a couple.


That would have to be Phottix's take on the B1 - those have iirc even TTL on the menu.
(I'd guess controlling other brands strobes would be difficult without standardizised ways to interact with them. Countless brands w/o clear domination, and a good part only with mechanical controls in the first place - where to start?)
