EOS Bodies / Re: New Full Frame Camera in 2014? [CR1]
« on: March 26, 2014, 10:19:44 PM »
I have looked closely at the A7r for that reason but there seem to be three big question marks - light leak, AF performance and IQ when using an EF adaptor.

The light leak story is imho overblown, thats unless you regularly shoot with dense ND filters. Mileage varies with lens choice - how tight are the tolerances of the mount and how susceptible to stray light effects is the lens as such?

IQ-wise the adapter contains no optics, its just an extension tube. While the additional tolerances introduced by the second mount are measurable most of the time just about every other source of error will dominate.

AF? I got the A7r for its manual focusing facilities. :)
Esp with the TS-E lenses AF is...well...you'd be waiting for eternity. With native lenses its ok, with promising developments(see a6k), adapted its more a proof of concept to me.

Am I the only person looking at the sensor dimensions and thinking "they get away with calling THAT medium format these days?... and people pay what?!"

Guess that depends on whether you look for the numbers or just for the best data you can get.
Most people who pay for dMF are in for the second reason.

They havent been able to make much inroads into the Nikon/Canon upper end of the DSLR market let alone MF.

According to their roadmap they're rather trying to approach that from the lower end, go for the upper echelons once they have a base. Looking at their market share in asian regions, the absolute performance of lets say the a6000 and A7r. the recent announcement of a CPS/NPS-like service and such the next 18 months or so might be interesting and prod Canon into actually doing something more exciting then slapping new labels on entry level bodies.

but the sharpness "issue" is too overemphasized IMO. 

Some people seem to forget that close to wide open the areas affected by lens defects tend to be out of focus anyway. And once you stop down to apertures that result in sufficient DoF the lens is at its sweet spot again.
Now reliable focusing , as well as more subtle rendering characteristics, are more relevant topics, at least away from shooting charts or similar.

EOS Bodies / Re: Canon's Plans For NAB 2014 Next Month [CR1]

Instead of a 7DC, they release a 5DC... 24MP Dual Pixel & 4K. Game over.

Even better: double the 4k resolution to get 4:4:4 output from a bayer sensor or at least mostly artifact free results. Preferable with full sensor readout for additional sensitivity & signal quality. For 30fps that wouldn't even be that much more workload then Nikons new compact handles, not to talk about using two processors. Throw in the standard visual aids for video.
All the video, landscape& studio crowds would love that.

I'm not saying it will happen quickly, but if technology advances to where the frame rate can be 24 fps and a full RAW image can be captured for each frame, we'll be there.

Well, Nikons V3 can capture 60 full res raw files, i.e similar 18MP to the 1Dx or the run of the mill APS-C cam, per second, or 20fps with tracking AF. So much for "quickly"  ;D

But how much effect that can have on photography is very genre dependent. For sports its quite an advancement. For anything planned not so much. And once you bring flash into the game its at least massively expensive (get me some Scoros, and that's w/o requiring high power) or way beyond that. Replace that <10kg mobile unit or some flashguns with multiple trailers filled with gear... 8)

As for picking frames from a video...both technical details like motion blur and artisitic&narrative decisions are often mutually exclusive, or at least not exactly helping each other. That's for absolute minimal budget/low quality, otherwise definitely unavailable material or fools.

I've browsed through most of the thread and I'm surprised so many are taken aback by this guy having his assistant (s) set the camera up on a landscape picture.

We could take a look at the credit list on those moving picture thingies that came up recently - everybody knows names like, lets say Kubrick, Spielberg or Tarantino. Not that much work on the physical cameras from those I'd wager, yet they're the most strongly associated with the final product. Even their DoPs have a different job description then the camera crews. Just because one can do multiple jobs on smaller scale productions it doesn't make micromanaging trivialities mandatory. Doing a models makeup on my own would end in "epic fail" anyway...  :-[

Canon General / Re: Review: Canon Speedlite Transmitter ST-E3-RT
« on: March 17, 2014, 06:40:31 PM »
I haven't had the same unreliable connection with my YN-E3-RT as you guys have, but It definitely feels cheaper, and didn't do well when I had it outdoors for a -30C shoot (I can't comment on if the Canon could have fared better).

As for reliability: I'd say the Canon is more reliable at being reliable - less "It works, most of the time at least". Either black or white, no greys in Canonland. Might just be a more demanding setting for the frequency evaluation program? Who knows?

At -30C most batteries go to sleep, and that small thing hasn't enough mass to provide thermal capacity or insulation to keep at least some warmth in and the chemistry going. In such circumstances Lithium cells work best, either the ~1.6V-1.7V AA-sized ones or if you want to go the distance replacing two AAs in series with a single CR123A primary might be an option. Those still work in conditions that would probably have killed your gear a while ago.

EOS Bodies / Re: EOS 7D Replacement Mentioned Again [CR1]
« on: March 17, 2014, 06:26:32 PM »

We aren't talking cell phone distances here. Most EVFs are recessed at around a quarter of an inch or so, pretty much always less than an inch. At around an inch, 3000-5000ppi would do it, but at a quarter of an inch, people with better than 20/20 vision are going to see pixels.

Your whole chain of argument is consistent in missing a vital point: there is at least one optical element in from of the display. I.e. absolute and apparent  size, resolution, distance to the eye,... of the display are decoupled, making the whole story somewhat amusing but nonetheless moot.

Also seeing those discreet pixels would require them to have sharp borders, absolutely no light bleeding to neighbor cells, nothing like the trinitron tube of old times. No effective AA-filterlike construct to blend colors.

Having pixels in the VF has some benefits on the one side, on the other: in favorable conditions now I see the structure of the matte screen. That's not really much better then it's electronic counterpart in the first place...

Canon General / Re: Interview With Canon Executives
« on: March 06, 2014, 12:58:49 AM »

Along those lines, I'm really looking forward to the implementation of single shot HDR. If you could use digital curtains and pack 1/125, 1/500, and 1/2000 exposures into a single 1/60 shot, then you'd have a hand holdable (for most lenses) single click method of producing HDR images.
It doesn't sound that complicated to implement, does anyone know of a camera that does it already?

I'd go so far as to make use of the dual pixel architecture, just read the diodes with different amplifications, esp as. Canon doesn't have an de facto ISO-free sensor.

Reviews / Re: Why the DxO bashing?

That particular quote comes from Gale Tattersall - the guy that used the 5D Mark II for House where they used the 5D Mark II to shoot the final TV episode. So what you're now saying is that a well respected professional is wrong?

Do you realize that G.T. is in the motion picture business?
I.E., esp. given the time frame of the statement, thats comparing of what remains after the cameras internal conversation, the lossy compression and then the color grading on top of that are applied vs. raw sensor data?

Canon General / Re: Review: Canon Speedlite Transmitter ST-E3-RT
« on: January 31, 2014, 09:17:46 AM »

Is the transmission distance any better between the Yongnuo and the Canon?
One thing to keep in mind: the RT system is based on a two way communication. No matter how much power you put out, if the response from the flash doesn't reach you you're out of luck. I.e.  getting more range then between two 600EX-RT is unlikely, and I'm not aware of noticable range differences between a 600EX-RT and the ST-E3 as transmitters.

Thanks for the explanation.  However, I wonder if the physical infrastructure needed to perform a global shutter wouldn't have implications for still photography.  A rolling shutter seems to be the necessary result of having slower processers/read rates (I could be wrong).  To pull off a global shutter I would expect you would need faster or more A/D processors and faster read rates.  I wonder if such hardware could benefit still photography in terms of fps and possibly (elephant in the room) noise.

Or you do it old school, with secondary buckets. Give each sensel the capability to put its current charge in a non photosensitve area. Then you have all the time you want to sample. Another option would involve a Kerr- or Pockels-effect based shutter.
But Canon wants more readouts anyway - DPPD-AF makes you want to potentially read the whole sensor*2 at the refresh rate of the current PDAF-sensors (and prcess that data).
Well, Sonys high end compact can read,process and compress to video 60 iirc 20MP-images per second, a similar core in a dual configuration could do quite a lot... 8)

If one values dynamic range and cutting edge sensor technology, it's pretty clear who the leader is now.
How many clients care about the sensor technology used? The closest I've been asked was "MF or small frame". In focus or not is also much higher on the priority, esp in sports, then some noise in pushed shadows, cue the colorblind AF in the Nikons and the red (induced) shift.

VERY interesting. Something has to happen in the Canon camp!

That depends on what the D4s can do - if it just narrows the gap the pressure is more on emotional side. Even a slight edge wouldn't have much impact. And seriously surpassing the 1Dx would warrent a promotion to D5. not just the incremental s. As for video: 1080p@60 would be expected, but the 1Dc can do that too - it would require 4K with RGB readout and at a decent framerate to get folks seriously interested.
I'd say the D800 is a stronger "something has to happen"-factor ;)
