Sony alpha NEX 6 Dynamic Range (JPEG)

Our Dynamic Range measurement system involves shooting a calibrated Stouffer Step Wedge (13 stops total range) which is backlit using a daylight balanced lamp (98 CRI). A single shot of this produces a gray scale wedge from the camera's clipped white point down to black (example below). Each step of the scale is equivalent to 1/3 EV (a third of a stop), we select one step as 'middle gray' (defined as 50% luminance) and measure outwards to define the dynamic range. Hence there are 'two sides' to our results, the amount of shadow range (below middle gray) and the amount of highlight range (above middle gray).

To most people highlight range is the first thing they think about when talking about dynamic range, that is the amount of highlight detail above middle gray the camera can capture before it clips to white. Shadow range is more complicated; in our test the line on the graph stops as soon as the luminance value drops below our defined 'black point' (about 2% luminance) or the signal-to-noise ratio drops below a predefined value (where shadow detail would be swamped by noise), whichever comes first.

Note: this page features our interactive dynamic range comparison widget. The wedges below the graph are created by our measurement system from the values read from the step wedge, the red lines indicate approximate shadow and highlight range (the dotted line indicating middle gray).

The most important thing to note on this graph is the curve at the top of the highlight range. The gentleness of the curve illustrates the NEX-6's ability to render highlights with a pleasing curve to 100% brightness instead of clipping off. As you can see the 6's default tone curve is all but identical to the 5N as well as other recent Sony cameras. The 6's dynamic range performance is among the top of its class, especially compared to Micro Four Thirds.

Color modes

The NEX-6 has a range of color modes which have a relatively small effect on contrast - Vivid, Landscape and B&W all create images with slightly higher contrast for example, but with essentially the same highlight range. Portrait mode decreases the overall contrast which can be beneficial for creating smooth facial features without harsh shadows.

DRO settings

As illustrated by the chart, the D-Range Optimizer feature brightens shadows and midtones, with minimal effect on highlights.

Which camera would compete well with the nex 6..?
Any opinions greatly appreciated.

I originally wanted to invest in a canon 700 d ( just missed out on a greal deal on the 600d ) but the fact tthat the viewfinder is optical swayed me.

Is there an all round dslr for amatuers coming from a bridge version with the following...
EVF.
Decent lens ( perhaps a Compact system type ) mid range 18-55mm or a little more
High ISO
Lighweight
Flip screen, preferably one which can actually swivel round to take portraits...
Touch screen is NOT necessary
And of course a decent battery which the camera makes tend to overlook...
I feel Canon have lost sight where Nikon is concerned whereas Sony and Lumix seem to have come a long way and are doing what Olympus did in the 70s and the 80s...
Again, any thoughts on the above..?

I am just about to purchase this camera on the basis that I can return it within 15 days if unhappy...
I thought I had done my homework when decidng on the nex 6 but I am unable to find out if it is possible to override the function of having the screen on.
It seems that the EVF switches on automatically when you place your eye close up to the corner of the camera ( thrus the screen goes off...) and the screen does the same when you move away from the EVF.

To my surprise there is quite a 'waste' of battery time...
Living in a sunny country means the use of an EVF is much more practical.

Can anyone give any tips on how to make the battery last longer.
Ideally, taking three on trips is practical. An external charger is wise too.
And the pc method when on the go is practical as well. Nevertheless, total control over the screeen makes sense nowadays.
I share your point too photosym. That does not make sense as a selling / marketing point. Is this the case with most sony cameras??

I don't know who designed this camera, but it certainly wasn't an active photographer. It would be a superb machine, but there's a massive design flaw. You can't use the self timer or an electronic shutter release when in HDR or Auto bracketing modes. Absolutely crazy!!! I've been in touch with Sony and they don't have any plans for a firmware update. I'm not sure if this applies to other Nex or Sony models, but be aware. This is the last Sony camera I will buy, I'll stick to Canon or Fuji in the future.

I agree with you photosym. This would be a great camera, but it is really useless in the respect of remote control bracketed photography. The remote control is useless when you can't have timers, and other manual settings. It is a shame.

I just bought a Sony nex 6. What a amazing camera. Yes you can use HDR and Auto Bracketing with a remote. At list via wifi with my android phone and ipad. Better than the Leica M digital. With more options. As a reporter I love this camera.

Appears from the manual no input jack for an external mic attached to the shoe for this camera. Will use the new mic on the Nikon 5100.

I ordered the new SHURE VP83F LensHopper Camera-Mounted Condenser Microphone with Integrated Flash Recording for this camera and it's std size shoe mount to record and video shoot indoor stage Band performances.

Anybody else tried an external mic mounted to this camera.

I just unboxed my Sony alpha Nex6 a few minutes ago.
I have several Panasonic Lumix's and a Canon Rebel.
The Sony, however, is the first camera I've encountered whereby I cannot simply recharge the battery in a compact charger!
Instead I have to connect a wire from the camera into the charger and thence into a wall socket meaning I cannot have second backup battery.
If I'm on vacation I can't simply leave a battery charging at a hotel room and go out and use my camera with a second battery.
I have to leave the WHOLE camera behind to charge!
Am I missing something here? It seems VERY odd.

you can buy original sony charger, I have it but i leave hotel with both batteries charged anyway :) in-camera charging is also great, do your all previous cameras have such feature?

+1, I wish Canon and others would add this feature. While external chargers are vital for certain uses (long trips with brief access to power for example) internal chargers are WAY more convenient. Just bring a USB cord and your iPhone's USB->power adapter and you can plug in your camera to suck some juice whenever you have the chance.

I certainly don't hear people complaining about how the batteries in their phones work these days, we just need to get used to the same thing with cameras (especially the "grab some juice while you can" part, don't wait for it to empty out!)

Just to update this, I didn't realize that you can't use the camera at all while it's charging (mentioned in an Amazon review). That's a very tedious element of this equation if it's true. I can imagine a LOT of situations where I'd want to review photos, make picks or just mess around with the camera while charging it.

It should "work like your phone" like I said in the comment above, if you can't use it while it's charging that's not like a phone. Of course, it IS like every camera previously if you only own one battery ;)

Any number of aftermarket and also (expensive but sure) Sony's spare battery and chargers will add external charging and spare batteries. Safe reliable aftermarket ones are not that expensive and will provide a much more convenient way to refresh the power than with having only one battery. I usually have up to 3-4 batteries always on hand for any primary cameras, two of which are always on the charger during vacations.

I guess in this market for consumer price wars, Sony can't include expensive batteries in the original bundles, at cut-rate prices, nor confuse the ever impatient general consumer who just wants things simple?

You're correct, it's very odd and another fudge by Sony.

LOL I love charging direct to camera, and yes we need to buy extra external charger, but you can just buy cheap chinese charger for around 10-15 USD, with that I can charge 2 battery at the same times, and also I can charge with powerbank when it need.

Hi!
Can anyone please explain me if I can add an PANASONIC 20mm f1.7 II pancake to this camera? Is it fully compatible?

Thanks

No that lens is microfour thirds only. This only takes NEX lenses. That is Sony E-mount

Direct mounting is only with SONY E-Mount Lenses, however you have the option to add a LA-EA2 or LA-EA4 adapter to use any Sony A-mount lenses with full Auto Focus features intact. This is also true for all AF Minolta Lenses that use the A-mount as well.

Also, with aftermarket mounting adapter solutions, almost any SLR lenses can be used with MANUAL focus. Canon lenses can operate with some adapters with limited AF functions as well.

I bought the RX100 and now I miss the viewfinder of my old P60. A movable screen would also be useful. What a pity...

@dpreview.com: As you know, the performance of a camera depends very much on the quality of the lens. What lens did you use to test the NEX-6, please? I couldn´t find any hints in the article.

I personally do not agree about adding a touchscreen to the NEX line of cameras. I simply don't like touchscreen and I know a lot of people that feel the same way.

Seriously what an odd thing to be worried about. As long as you can disable it why deny it to those who would find it helpful?

Providing a touchscreen, with the ability to enable/disable will meet 100% of user preferences no? ;) Instead of battling opinions on if it should be there or not? I think that's what the review implies...

As it takes RAW files all of these details will be on the file along with shutter speed, aperture used etc.
