falconeyes: > The new α9 also supports uncompressed 14-bit RAW, ensuring users can get the most out of the wide dynamic range of the sensor.

Still no lossless compressed raw.

@falconeyes. I understand what you are saying as Hensel pioneered this idea with their Freemask flash feature.
However I have yet to hear of anyone actually using it or any variation of your technique.
As flash cannot be used with the e-shutter this is a non-issue. It may have applicability with a 1Dx or D5 but again, I haven't heard of anyone really trying to set that up.

Photomonkey: So basically it is a FF 24MP Olympus EM-1mk2 with fewer lenses? ;)

Oh yeah, the Oly gets 60FPS.

My comment was obviously tongue-in-cheek however we cannot overlook the fact that Olympus has a very responsive camera in the EM-1mk2.
I am also aware of the µ43 vs. FF differences.
I would also note that as a user of both these formats there is a lot less difference in most typical usage than many would claim.
Yes, shallow DOF on FF is easier but as that is a small part of so many photographs.
Yes, noise at high ISOs is an issue but I have regularly shot at ISO 6400 in dark wedding venues and have gotten very usable results.
The other fact we need to look at is how images are displayed.
The VAST bulk of images are shared at 1200pixels or less. Phones do well in this fight.
If you need large prints you will need lower ISOs or FF at high ISOs. With all the whining I hear on these boards about the cost of things I wonder how many actually spring for large prints to actually see the differences.
At 11x14 and below µ43 and FF are almost indistinguishable at ISOs up to 400.

I think it is useful to remember that electronic shutters (as we have them at the moment) are really just full-res video capture.
IOW rolling shutter is present, flash is not available, and flicker in some light sources is present.
For many applications this is fine. Silence is wonderful for weddings, wildlife, candids and street photography.
Flash is still limited to the maximum sync speed of the mechanical shutter.
I would also add that when using flash, the silence of the shutter becomes moot.

In reply to:

(unknown member): How bad will the rolling shutter be?
Most A7 series were pretty lousy, some 24MP versions measuring over 30ms. The A6300 was 39ms.

And this is bothersome: Electronic shutter mode. At apertures smaller than F11 (F-numbers higher than F11), focus will not track the subject and focus points will be fixed on the first frame.

Well, it puts it in perspective.
High frame rates are the key selling point of this camera.
For me the real significance are the improvements in the finder, controls, battery and card slots.
A true global shutter with flash sync at all speeds would be a real breakthrough.

Photomonkey: " extremely low rolling shutter thanks to the incredibly fast readout speeds of the new stacked CMOS sensor."
Just how fast? As this is a camera geared to sports and wildlife photographers the 20 FPS needs to hold up to action stopping shutter speeds.

Scan speed is critical because we already have the Oly EM1-mk2 producing much higher speeds at 60 fps at full res.
20fps at 24 mp doesn't seem so impressive UNLESS it has real action stopping power.

@rrccad. Yes, in florescent light you need to shoot at under 1/60 sec or you will get banding.
This happens with my cameras that have e-shutters.
E-shutters also disable the hotshoe to prevent flash use.

CONT...

IMO Sony probably has a much higher readout speed (they certainly clim it but do not offer a spec) but unless it is blisteringly fast, it will show warping artifacts that will be severely criticized by potential users in sports and others needing action stopping speed.

@LDunn, The sensor is operating in a different manner in e-shutter mode.
In e-shutter it is effectively a high frame rate video scan.

In mechanical shutter mode the sensor is accumulating light with the mechanical shutter cutting off the light supply. THEN the read out of the lines begins and thus is not critical to the rendering of the image.

Sensor readout speeds are important in e-shutter because of rolling shutter. Thus all the wailing about video in DSLRs and cameras not having a global or mechanical shutter.

As for the 1/32000 sec speed, that is the the amount of time each line accumulates light. However it takes approx. 1/60 of a sec to read all the lines so the last line is read 1/60 of a sec AFTER the first line. So action is stopped at each individual line but the entire image can exhibit warping due to subject motion during exposure.

The camera has a mechanical shutter that is probably the same as in the A7RII. That limits flash sync to 1/250 sec.
The e-shutter has a top speed of 1/32000 sec but that is only the effective exposure time, not a measure of action stopping.
I have no idea what the scan speed of the sensor is or if it employs a different strategy altogether. However, current e-shutters read line by line in about 1/60 sec. Thus the action stopping ability is effectively 1/60sec irrespective of the exposure speed of the e-shutter.
With the mechanical shutter the maximum shutter speed is 1/8000 sec with real action stopping power.

J A C S: The skin colors are inconsistent - sometimes just right, sometimes too reddish. Maybe the Provia profile is not the best, have not downloaded the RAWs to check myself.

I am of the opinion that is shot with window light and thus is quite blue.
Blue cast will not show up obviously on the clothing or watch but the skin tone (even for a pale Seattle-ite) is very blue.
The others seem to be shot with strobe and thus are more consistent with each other.

@LDunn, Yes Jacques Henri Lartigue becomes hip all over again.;)
Actually, as you probably know, that is only true for a single subject going in one direction. If they travel the other way they look like they are leaning backward.
Also spinning blades (helicopters, swords etc) will render bent.
The real issue is multiple subjects (soccer game, hockey) where subjects are moving quickly in different directions.

@Josh, this was my question as I see rolling shutter in action images from my Panasonic GX7 and FZ1000 when using e-shutter.

I guess we will have to see how it works IRL.
Seems a brilliant camera but not what I need as high speed sports etc are not my job.

Maybe they are using AWB. That is a recipe for varying color.

In reply to:

noisephotographer: Disadvantages of the L16:
-Allegedly (that's what Light said last year) only 3 MP in-camera images (you need to connect the camera with your computer in order to get more megapixels)
-at 150mm you likely get only 13 megapixels, so you don't get 5x lossless zoom at 52 megapixels, at 150mm noise will be likely worse, too
-macro: not all cameras have the same minimum focus distance, therefore not all can be used => more noise and probably only 13 megapixels
-flash: only dual led
-no optical image stabilization
-shutter speed only up to 15s
-iso only up to 3200
-No evf, no tiltable display
-battery not replaceable, though you can buy a camera grip which has an additional battery
-the internal storage of 238 GiB is for only 1000+ images, so you could expect that one raw image likely requires more than 150 MiB
-video: probably only 1 camera at the same time => bad image quality
-some sample images show visible artefacts / much noise although only 3mp, and there is a 6.7 mp image with noticeable corner softness

Maybe, but it is still very compact and that may be enough to sway people if the IQ is stunning.
We will have to wait and see if it is another Dale.

Fredrik Glckner: Can it take 3D images? If not, sounds like a missed opportunity, given the number of camera units.

On the other hand, perhaps 3D is simply so yesteryear that it isn't on anybody's map anymore.

Note the resounding thud that met the 3-D TVs.

Robemo: Impress would-be clients with gear? Really? Is it just me having bad luck for more than 40 years with much more cirtical and smarter customers? The first thing most clients ask is your portfolio and references. Rarely do they show any interest in the gear I use. Actually most of them don't give a hoot .... unless they have photographic knowledge and very specific demands. Again, that's rare ...

True, except for the flood of newbies in the field who are gear-centric and beleive their potential clients are as judging as they are.

In reply to:

Contra Mundum: Why is Fuji so hung on film simulations? Those films in the past were really restricted to kind of colors and tonalities they could reproduce. A digital image has so much more flexibility that restricting the processing to flawed films of yesteryear is really bizarre.

When I was shooting weddings (~2000 images) I had no problem adjusting images in LR.
Depending on a "look" from Fuji is akin to the noob asking "What settings are best?"
