thx1138: 200 f/2.,8 or 400 f/5.6 much more DOF than 400 f/2.8. We need to see how AF accuracy is when use the big superteles with very small DoF, eyes have to be nailed. This will too much at 20fps for any AF to get reliably IMO. Can you run the A9 at any fps below 20, like can you set a custom hi and lo shooting speed? Mostly I'd run it with lo set to 8fps, hi set to 15fps

In your dreams, Any one can boast rubbish claims behind their keyboard but comparing your A7RII AF to 1DX just shows you are so full of it, it's hilarious. A7RII can't even beat the a6300 in AF, which gets demolished by the likes of D500.

dash2k8: Lots of naysayers spewing stuff without solid evidence to back up their words. Keep up the good work!

Translation: If you're going to hate on this camera, don't hate it because it says "Sony" on it. Don't hate it because it's mirrorless. Hate it because of Reason 1, Reason 2 and Reason 3.

Pretty much sums up how Sony fanboys treat anything with a Canon or Nikon label. Never shot them, never will own them but hey their camera is way better, only fools buy Canon blah blah blah.

Live by the sword die by the sword.

beavertown: Who would have thought Canon could make competitive senors now? Why not Sony to overcome the drawback of mirrorless system to catch up with the pro dslr Cankon level someday soon?

Only a true armchair fanatic would be complaining about Canon's latest sensors. Go and take some photos rather than sitting on the lounge measurebating and pushing shadows 6 stops, assuming you own a camera.

In reply to:

beavertown: They should continue to make the A7x for people who need high megapixel just like the 5Dx does.

A7RIII coming soon don't worry and the camera more relevant to 99% of people. As long as it gets better EVF, bigger battery, new UI, better ergonomics, and is at least 7fps with 42-50MP, it'll be more than enough.

Why bother with this? The A7III's will be announced soon and will get a large part of these improvements anyway. You'd be mad to get the A7II's unless you are expecting deep run-out discounts.

This is the bottom end of the change over price and still no 400 f/2.8 in their kit, so it's not going to happen for a huge % of sports shooters. Wedding photographers and maybe golf shooters would switch. Golf shooters can't take a shot until after the golfer hits the ball currently, silent shooting allows them to shoot the whole swing.

Any way talk is cheap 99% of the white noise on dpreview is from those that will never ever buy the A9 or own or touch a supertele but are full of absurd doomsday scenarios for pro DSLR users and know better of course.

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.

In reply to:

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.

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.
