On article Dell announces 4K HDR10 monitor (88 comments in total)

For UHD I'd much prefer a 32" version, so I hope this is coming. Be aware judging noise and sharpness on a 4K monitor with small (< 0.2mm) pixel pitch is problematic, Noise looks much better than it would on even say 2560 x 1440 monitor and everything looks sharper. It's best to judge noise and sharpness at 200%. As an example my 5DsR ISO 6400 shots on my 15" Dell XPS UHD laptop look like about ISO 1600 would on my 27" 2560 x 1440 monitor. The pixel pitch of that 27" monitor is 0.233mm, while a 32" UHD version has a pixel pitch of 0.18mm, so about 30% smaller. The 27" UHD monitor would be around 0.13-0.14mm.

///M: The future is not in 400/2.8 lenses, being able to move faster on the sidelines of a sports event or other assignment will be more incentive to switch than the 20 fps with no blackout. I think the longest lens Sony will need will be a 300/2.8. An ideal kit would be: 2 bodies, a 100-400, a 16-35/4 and a 1.4x teleconverter, all made possible with the high iso ability of the new sensors. No 70-200/2.8 or 400/2.8 needed, the 300/2.8 would only be needed occasionally when a 600mm is needed. The 2 a9 bodies weigh what a CaNikon sledgehammer weighs. Imagine getting out of your car at an event with 2 bodies with these lenses, and a vest with a few accessories and no boat anchor lensese to lug, fast and nimble, and silent at events requiring it. I see venuse shutting down noisy DSLRs very quickly now that an alternative exists, also.

//M clearly thinks being an armchair sports pro means he has all the answers. No most sports shooters never stop down their 400 f/2.8. What are earth are you smoking. Also let's see you shoot the cricket with your 300mm when the fielder is catching a ball 150m away.

Why would a 200 f/2 on APS-C be similar to a 400 f/2.8 on FF, you still end up at around 300mm effective FL and f/3 effective aperture.

Oleg Ivanovskiy: I'm not convinced with all this talk about A9 super anti-distortion electronic shutter until you show me the proofs, side by side. So far mechanical is good and electronic is not. I highly doubt that this new ES can beat mechanical at 1/1000 of a sec. in terms of distortion AND noise. A7R II would have been looking good in that shell though, with AF joystick, 2 memory slots and AF-ON button.

This is not a global shutter, the entire sensor is not read at once, there will always be some level of distortion, Sony has greatly reduced it with the stacked sensor but they have not eliminated rolling shutter completely. In a shot I saw of a golf swing the club still had a slight amount of distortion but was reduced about 95% compared to the A7RII shot

RubberDials: So according to the pros in this article, for Sony to be viable they have to offer back button AF, a 16-35/2.8, 70-200/2.8, 200-400 and a 400/2.8 or 500/4 and offer compatibility with existing camera bags.

They've installed back button AF.
They already have a 70-200/2.8
They just launched a 100-400
A 16-35/2.8 has been rumoured for a long time and is likely to be imminent.

They don't have a 400/2.8
They have a 500/4 in A mount.

They're probably not working on the bag.

So just to be clear you don't get it right. The 500 f/4 in A mount will not be used, the AF performance is inferior with adapters, the eye AF won't work, and the shooting speed is limited to 10fps and apart from that it's the most expensive 500 f/4 on the market and the heaviest and the has the worst mfd and has no IS. IBIS is not as good for superteles.

In reply to:

RubberDials: Genuine question. Can someone explain the back button AF need for me?

I noticed right away that Sony had added this button. Why is it that sports togs need this rather than focussing by just depressing the shutter release?

You can separate metering and focusing with the back button. Shutter can be used to lock exposure and you can focus and recompose more easily by having the two separate.

J A C S: I guess HDR10 is 10 bit.

How do you have a complete 10 bit flow with either Win or OS?

Well you buy a graphics card that supports 10bit output like a quadro or firepro and use apps that are fully colour aware like PS and use a fully colour calibrated workflow.

Miki Nemeth: Yes, this is a brilliant article, and completely in synch with what I think about the A9. Thank you, RB. You never disappoint. I regard the A9 primarily as an advanced enthusiast wildlife camera today. As for the lenses, a $10000 400/f2.8Lii is enormously big and very expensive, but can give two stops more light, four times in total more than the Sony FE 100-400/f5.6. So, if sports photographers cannot live without this extra amount of light in stadium/sports hall environments, then of course, Sony is out of luck now. On the other hand, it would be really interesting, if a (sports) photographer took the hassle, and made comparison tests to see, if a brutally expensive rattling Canon 1DXII + 400/2.8 giant is so much better for sports photo journalism than a totally silent, much cheaper and smaller A9 + 100-400/5.6 in practice? Sony gave the camera to sports photographers, as B. Smith reported. Has anyone collected and published their opinion?

Miki please stop, you are trying to make what you think are rational points that are anything but rational. If you have never used a 400 f/2.8 for pro-sports then you can't begin to imagine the difference between that and an f/5.6 zoom. These guys are often pushing 12800 ISO or more under lights and there's a snowballs chance in hell they'll want to push that to 51200 or worse as well as have far worse subject isolation. The AF of the 400 f/2.8 is is also noticeably faster and the IQ is as good as it possibly gets. As for wildlife, no serious wildlifer would think they could get away with 400mm even on a 50MP camera, let alone a 24MP FF. We are using 500/600/800 with 1.4 and 2x TC's

Damage control from DPReview...

Angered fanboys from Canon Nikon are not clicking on the Amazon links anymore. QUICK, release a new article downplaying the previous one!!!

Almost as bad as stupid Sony fanboys that fantasise about buying $4500 cameras, based on marketing hype. Of course 99% of them will never buy anything above the RX100 but will tell working pros who use other brands that of course they know what's best for them.

davev8: you say "With the a9, you'll save a ton of weight,"......are you telling me if you had 2 camera bags 1 with a DSLR ..3 F2.8 zooms and a F1.4 85mm prime +batteries etc the other with the A9 ..3 F2.8 zooms and a F1.4 85mm +batteries etc you could tell which is which by picking them up ???????
yes i know sony has no UWA F2.8 zoom.....but it will be as big as other F2.8 UWA zooms when they release one.. as the sony F4 zoom is an big as other F4 zooms

Yet again ignoring the fact the A9 will never be shot without a grip by the vast majority of pros, so the weight advantage is clearly not 850g in the real world. They'll need the extra size and heft to handle the mythical Sony 400 f/2.8 if it arrives one day.

In reply to:

T3: Let's all keep in mind that-- as good as the A9 is-- it's just the first generation! It's basically Sony's first crack at a pro sports camera. And it's a damn good start. Not bad for a first attempt. If this first iteration doesn't quite cut it for you, there will be an A9II, A9III. Sony iterates pretty quickly. And they certainly seem to be listening to user feedback. So people should continue to be vocal about whatever weaknesses they see, so that Sony can make those changes in future models. People tend to forget that camera development is an evolutionary process. But the key for companies is to listen to feedback and to iterate quickly. Some companies do these things better than others.

Hardly a first attempt, 3rd generation but let's not worry about those facts. It's a minimal evolution of the A7 series with a fancy new sensor that allows nearly all the headline features. Ergonomics are still poor enough that one can barely get their fingers between the 100-400 and the grip. For the intended use, there's no reason on earth the A9 had to follow the A7 design.

AbrasiveReducer: I don't expect Sony to pass Nikon in sales (nor do I care) but with all the money Sony is throwing at cameras, it wouldn't be difficult to surpass the quality of Nikon's repairs and support.

Sony service means outsourcing to third party, they treat their cameras like you would a toaster

patrocal: Let the real reviews roll out before crowning this the messiah. All Sony cameras look great on paper until the problems like overheating, poor af in real life dim light situations and horrendous rolling shutter (just to name a few) show up.

Let me guess, kikiriki has never even picked up a professional camera, let alone shot one. Forums addicts read product brochures, real photographers get out in the field and use their cameras day-in day-out and know exactly what's good and bad and what's hype.

Ostrich meet sand, you know what to do next.

As Yoda says, the hype is strong with this one. Trolltran will buzz around these threads telling every one how this is the best thing since sliced bread and is as likely to buy one as Trump is to find a brain. Well at least Sony can rest assured their glossy marketing brochures impress some people.

Here's why I'm impressed, I'm not a pro sports or wildlife shooter and think a 100-400 zoom will cut the mustard.

As it stands this is a half-baked release that most pros are already scratching their heads over. Sony would have made a massive impact by having a 400 f2.8 on release not the zoom, which they will never use.

Also they wont ignore the ergonomic issues of there not being a enough space between the grip and the lens. You can barely get you fingers between the 100-400 and grip.

Wedding photographers will flock to this however for the totally silent shooting and eye AF.

photog4u: If you're Canon, what do you do here? Try to develop an A9 killer to slow down the Sony Machine? If you do that and succeed you'll undoubtedly cause harm to your own flagship. So in point of fact, you'd have to be willing to switch modalities and go full-on mirrorless, I think. If you do nothing, you'll most likely be overtaken soon, perhaps even be deemed obsolete, as many have suggested is the way of the DSLR...much like that of the clunky cell phones we used to have installed in our vehicles were replaced by handheld devices. Canon has some tough decisions to make and make fast as they are facing quite the conundrum IMHO. They must at least take some comfort in the knowledge that they are not buying theirs sensors from their would-be executioners ;)

Well they might panic, then again they might wait and see how the Sony actually performs against it's 1DXII and Nikon's D5 in the field. Sony marketing brochures pump the hype and every camera they release they claim has the worlds best AF which turns out to be utter BS. No doubt this will be their best and very good, but I'll wait for actual experienced bird photographers, guys doing extreme sports etc before I believe anything I read from Sony.

Even if this does indeed turn out to offer AF performance on par with the Canon and Nikon flagships they still have no native FE mount superteles like the bread and butter 400 f/2.8,. No pro is going to dump $20-30K worth of gear to jump onto a camera that so far only has announced a slow 400mm zoom. It defies belief that Sony would market this camera as it did and not have a 400 f/2.8 to announce at the same time. That would have shown the real commitment needed to convince pros they are fair dinkum.

thx1138: Ok finally a useful longer tele zoom lens in FE mount, specs are good, price is not which we expect from Sony. Hopefully it will drop over time.

The A9 is only 24MP, so 400mm won't cut it for birding, we need Sigma and Tamron to release FE mount versions of their 150-600 zooms and Sigma to release FE 300/400 f/2.8 and 500/600 f/4. The Sony versions will be ludicrously priced like their current 500 f/4 that no one buys, but will they even be released in this decade.

@ abdoboy, I think you be wrong, plenty of the best bird photographers use the 20-21mp 1dxii, D5 for birding, they just have 500/600/800mm lenses and use TC's. This has 15-20% more pixels so is a slightly better bet in that regards. Given the potential AF capabilities for tracking this will actually be a birders wet dream. But I would prefer native FE mount glass than adapting my Canon lenses,. However, if the Canon glass still performs admirably with adapters on the A9 then I'm very keen to get one and complement my 5D4.

The Fat Fish: Shame, the rumours of a real video fix for the 5DIV sounded so real and promising. Canons attitude towards 4K has been appalling. I've been toying with the switch to Sony over the past few years and now it's finally time. I had hoped to wait for the 6D MKII announcement but If they can't do it on the 5DIV, they won't do it on the 6D MKII.

And yet the poster boy for all things good, Sony, which gives the A9 excellent 4K video features but does not offer s-log and there's not a peep from the same trolls trashing Canon.

Noogy: It is only when competition leads to the raising of the performance bar that innovation becomes truly biased to customer benefit. While I do not expect an overnight transition of Canon sports shooters to Sony, this definitely gets Canon's attention to speed things up or risk bigger market share reduction down the road. Appreciate what Sony is trying to do to the digital camera market.

Maybe Sony will have to release some actual pro supertele lenses if they are to be competitive at all, 400 f/2.8m is the workhorse, where is it. No pro is going to use a 100-400 f/5,6 no matter how good

raminm: All the new improvements, the new stacked sensor, the speed enhancements and AF improvement are interesting. However, none of them makes this camera revolutionary enough to mark the beginning and a new era in 'photography'. Mirrorless itself, in essence is not an unprecedented design. Mirrorless in essence is a reshape of the old rangefinder camera system then modernized for the digital camera technology and, rangefinder cameras have been around throughout the 20th century.

The important point of this camera is being missed by most people here:

'This camera has made the mechanical shutter now extra and unneeded.'

Huh, this camera had to keep a mechanical shutter as well just for flash. So what are you smoking it hasn't completely replaced the mechanical shutter. But it's gotten damn close.
