armandino: a couple of things Sony really needs to address:
1) card filing system, often asking for recovery
2) just stop requiring updates via a PC. What a joke. We should be able to stick the update in the SD card and run an in camera update.

I never get the recovery requests from my camera. Are you deleting pictures from the card on your PC?

magpiedom: Just sold my Sigma 35mm Art. Soulless piece of crap. The sample photos from the 40mm don't inspire me either. They too look clinical, with poor contrast. And 1.2kg, that's as much as my Gitzo traveller! Insane.

I found the Zeiss 35mm Distagon f/2 is a far superior 35mm lens. The images have waaay more depth, better colour, it's lighter to carry, and a touch sharper through equivalent apertures across the entire frame (Sigmas have a tendency to be sharp in the centre frame only). Some will say Sigmas have the advantage of auto focus, but I found my copy often missed focus (no I did not invest in the dock, why should I have to do that?). My copy was also too slow to focus for my liking. With practice some practice and stopped down to f/4 i found I got many more keepers on the Zeiss.

Maybe the rare focal length of the 40mm is attractive to some.

Of course. We see this bias in everything (in photography and more). You are also right about the quality of the Brands. Zeiss is much more older than Sigma. In reality, Sigma is born with the aim of becoming another Zeiss (see Sigma CEO's interview).

However, DxO's lens benchmark table lists Sigma and Zeiss as neck to neck in top slots. This is why these two companies deserve a blind test. If I had the means and resources to make such a test, I'd already present you the link of the test page. However I neither have the lenses, nor the time to cover all plausible scenarios for the test.

When I started photography 20 years ago, Sigma was a "discount" lens brand. However they are not the same underdog now. They are dedicated, and left their lower-tier complex behind. They may not be quite "Zeiss", but they are not another "Samyang".

@magpiedom
I didn't use either lens, but I have deep respect for both companies. However, your claims need a blind test to verify to remove brand bias.

Tungsten Nordstein: A great way of delivering a deadly air-born payload. Great idea FAA.

@Tungsten Then we should ban cars, backpacks and other storage equipment too. We cannot trust what's inside these trunks or bags, or steel mugs, or....

LessMirrored19: According to tony Northrup video about color science blind test
The poll results were
1) Sony
2) Fuji
3) canikon
... it's just been fashionable to hate Sony colors.

@MrPapaBear, for me accurate colors means more choices. When I shoot RAW, it gives more headroom. I'm an old Nikon user and a new Sony user. At the end of the day, I've found out that Sony's camera design philosophy suits me more, and I enjoy photography more.

I have no intention to turn this argument into a flame war. People have different priorities and choices. This is why we have many different camera manufacturers, different approaches and technologies. I've always welcomed Nikon and Canon into the arena, and I still do. Panasonic is coming, and I'm still waiting for Pentax, because they're also very knowledgeable about this stuff.

The aim is to take photos, not to compete with cameras. There's a proverb I like a lot: "A normal person uses the audio system to listen music, while an audiophile uses music to listen to his audio system."

We shouldn't be that audiophile, but should go out and take photos.

@Mr PapaBear, @webber15, @NOWHITELENS; Sony A7III also has the most accurate colors crown too. See it here: https://www.pdnonline.com/gear/cameras/the-best-cameras-for-color-reproduction-ranked/

The test is not according to someone or something. It's a scientific test.

princecody: Would you rather buy this or new rumored EM1X?

If I need a camera now, and I decided to buy it now, I'd rather take the options that I can buy now.

Otherwise, you can always wait for some rumored camera, indefinitely.

rbach44: Waiting to hear how Sonys are still better. FPS? AF Points? "better technology"?

PS just played with the Z7 at B&H yesterday and its feels like a fantastic camera. The first mirrorless camera that has interested me since my dark months with an A7...

Sony has its own set of strong points for consideration. Nikon also has its own. There's no need for throwing stones while we all are sitting in glass houses IMHO.

I used Nikon for a decade, and I love how they build their cameras, but Sony's philosophy is more suited to me. I only discovered it after getting an A7III though.

I applaud everyone for moving the technology forward in their own ways.

nandbytes: Something Sony could learn from, not so hard to make a decent weather sealing is it :-P

The hardest thing in engineering is to make something marvelous, and make it look simple and something not to sweat over too much.

Nikon gets two points at once IMHO.

Pierre Louis: Fantastic news! Hopefully global shutter and a stepless 'ND filter' can be added to the GH6 (probably will have 4k or 6k max) 8k is needed, but moreso for 360 cameras IMO.

@SteveAnderson

When plasma came out, it had some disadvantages. Most important was burnout (losing intensity in all colors) or burn-in (having that CNN logo indefinitely). Some people also irritated from the buzzing which gas excitation circuitry made. Also rapid flashing really irritated some people. All of them are also valid for OLED, but at least they're working on it and advancing visibly.

Also they weren't actually cheap. Not everyone can change a panel every two years. I trashed my L90D+ because its board fried due to a component failure. I've given away T220 after 10 years, because its cathode started dying, and I needed something bigger. Possibly my current panel will live around 10 years or so, if something won't die during the time period.

@SteveAnderson,

We probably witnessed the same timeline then. Consumers always have different priorities. Some want appearance, some want the performance. This is why we have choices.

Honestly, I'm not that picky about "video" performance of my monitors, because I generally write the code which drives computations or edit the half-bad photos that I took. So reasonable color accuracy and low-fatiguing is acceptable when compared to eye-drying CRTs with massive electron guns and glass.

I'm a happy camper currently.

@SteveAnderson

I was using LCDs which rivals today's calibration accuracy 10 years ago (Like Hyundai L90D+), which also had refresh rates which rivaled today's mid-high end monitors.

LCD may be designed to show text well, however there were always exceptional LCDs with exceptional qualities. LCDs were easier to produce than CRTs, and they provided higher profits with faster production times. As a side-effect we were able to improve them a lot, since the technology was under-developed.

With multi-temperature LEDs and carpet lighting, they increased the color accuracy and local contrast.

Gaming LCDs were always prioritized other things. Dell's UltraSharp series and HP's enterprise LCDs is a different user experience all over. They are non-fatiguing and show everything well. Dell's monitors also factory calibrated per-panel and they come with a calibration certificate tied to monitor serial number.

On the other hand broadcast industry needs all the flexibility they can get.

You cannot tell players to slow down to allow cameras to catch them in a sports game, or in a race. Soccer broadcasts love the ability to crop to zoom, to analyze the game for example.

@SteveAnderson Because it'll provide more detail and higher sharpness if you scale down it to 4K.

Also you can use the higher resolution video to crop, to track subjects or just use untouched video on a very high resolution panel.

It provides more possibilities.

Tony Northrup: There are some huge flaws with the DJI arguments:
* The Phantom 2 is outdated: The current P4 Pro is 39% heavier & 12 MPH faster
* Drones can't fly that high: PLEASE. Google "DJI Phantom 10,000 feet"
* The test didn't exactly match the FAA tests: That's OK... It's still a useful data point.
* URDI is biased, they should have used ASSURE tests instead: Check ASSURE's 'external advisory board' to see bias. Hint: it's all companies involved in UAS, including DJI.

I'm NOT saying we need to freak out about drones hurting airplanes - I also think the original story was blown out of proportion. But using irrelevant nit-picking & DJI's legal budget to silence them & possibly scare off future objective testing isn't ethical.

@NacMacFeegle Neither the air around the wing have enough force to deflect the drone, nor the drone is subject to fluid dynamics since it's not fluid.

Probably they were unable to fit the propellers to the canon. Propellers are too fragile to create damage on the wing anyway.

In experiments and simulations, exact science is generally not possible. Simulating well enough yields results within ~98% of reality, and this is enough.

The laboratory (URDI) can conduct bird strike tests, I think they can conduct drone strike tests too. The laboratory has the relevant know-how and methodology. In other words, they know what they are doing.

DJI's respone is literally "panic".

ozturert: It is a horrible camera, just because it is not Sony.
According to some people here...
No no, just ignore all advantages and focus only on weaker points. That'll make you happier.

@HosseinG, Yes, the reliability of flash media is much better for consumers and mid-level loads, however it's not completely perfect. Even today, the problem is still present. Tony Northrup lost a card during EOS-R review. Last week, a three week old SSD of my office mate had died in an instant. Embedded devices are meticulously engineered to minimize SSD writes, but it's invisible to the user.

Really write-optimized storage devices exist and sell for around twice the price of consumer/mixed load drives.

The technology you're telling is SMART and is a standard for hard drives. I'm not aware SD cards have a similar support, but will check some cards that I have. BTW, SMART doesn't always show correct data. I had drives died unexpectedly with perfect (or very good) SMART stats.

Because of my job, I'm handling much more computing devices than an average consumer, even professional, and I'd never want an embedded, non-replaceable storage device in my camera which will wear eventually.

HosseinG, Flash storage is not an exact science. The reliability we are seeing a is a combination of wear leveling, cluster rotation, real time remapping, and a lot of self monitoring and self-healing which are all invisible to the user, even to the camera.

These technologies keep a flash storage medium alive, until it doesn't. A single error in cluster remapping and rotation can render whole card inoperable. Not "format-recover-reuse" inoperable, but "It's now a very expensive camera bag pin, nothing else" inoperable.

I experienced this things from $4 cards to $4000 storage drives. It's better to take no chances and write to two cards at the same time.

About in camera memory: It wears off. If you shoot a lot, it wears off quick.

Charbax: Please Sony for APS-C and Full Frame, I want:
- Flip out display
- 4K60
- 10bit 4:2:2 HLG
- H265 (lower bitrate, same quality)
- Long battery life
- Dual SD UHS-II card
- Unlimited recording (no 30min limit! I don't care about the EU! Just pay the tax or sell an unlimited recording unlock)
- Much better IBIS than A73, please at least as good IBIS as GH5, figure it out.

Bonus things that I would also like and I think you should be able to do:
- Live streaming by WiFi and Type-C to Ethernet, Type-C to multiple LTE dongles with bonding (like LiveU/Teradek functionality built-in directly)
- In-camera basic editing, trim/join, titles, intros/outros, watermark, easy drag and drop UI on phone to process in camera
- Live multi-camera editing, change to camera nr2/nr3/nr4 by tapping on screen, live preview other cameras all over WiFi or Type-C to Ethernet
- Type-C HDD/SSD safe dual backup before dual SD formatting, direct record to Type-C HDD/SSD also
- Backup power in camera for battery swap.

GH5's IBIS allows hitting edges of IBIS coverage and jerk back to center. Sony's IBIS prevents edge hitting at all costs. I personally prefer Sony's IBIS implementation.

Some of the bonus features you want easily needs hardware to increase camera size and shoot the price up, since it needs some hefty data transfer backbones with limited latencies.

I'd rather put these features in a video-first hybrid too. I'm pretty happy about A7III's feature set *as a photographer*.
