Reactive: This is a truly obscene price for such a tiny robot.

For this price it could have at least looked like BB-8 or R2-D2 or had an Apple logo on it.

Laowa making some fantastic products now like the 15 f/2 zero-D FE, qulsity is right up there with the best. Lenses look great and are a good price considering build and IQ. Looks like another winner at great price.

It's actually the Canon 400 f/2.8L IS II, that's why there is no lettering on the switches.

Anthony MC: New model and it is already behind against its competition. What's wrong with Canon? Why wont they give us a product that's not behind in tech?

It's not so much behind in tech as deliberately feature crippled. Why offer 4K only to totally gimp it with with massive crop, and worse still no superb DPAF. This sort of crap drives me insane. There is no reason on earth they had to do this. They could have easily used full sensor read-out or at worst say a mild 1.2x crop then oversampled the data down to 4K.

Rest of the camera is pretty nice, but having used DPAF for 4K video in 5D4, now way I could be without it. So I'm still blacklisting Canon mirrorless for this and the lack of lenses. The other pitiful thing is the crap 15-45 f/6.3 for god's sake.

thx1138: It's no better than the 135 f/1.8 as a "bokeh master". The 135 is superior in a way. It goes out of focus faster once out of the zone of DoF and it's blur circles will be the same size as the 105mm when well outside the zone of DoF. Given it weighs 0.5kg less and takes much smaller and cheaper filters why on earth would you bother with the ludicrous 105mm. It might make the better astro lens I guess but that will mean a tracker.

That's a beautiful photo, but the stars aren't pin sharp, there are small trails.

The lens at least looks great. Good to see Tokina move away from their older stodgy design. No more MF clutch ring either. Hopefully under a 1kg, preferably under 700g, but it looks big.

Also hope the AF is not as hit or miss as Sigma's.

So all the Sony users, get your backpacks loaded, buy all of the lenses in FE mount and lug around about 9-10kg with you, but I'm sure Sigma has a buy 8 get 1 free deal coming.

Daniel Bliss: And in true Sigma fashion, any filter size that Nikon makes too big, they can make ridiculously bigger still. No thanks.

PS, one-and-two-thirds kilos for a 105mm? You've got to be kidding.

I was specifically talking about background blur. The diameter of the blur circles are proportional to aperture size. So OOF highlights well outside the DoF will be same size for the 135 and 105. The 135 as you say will go out of focus faster though. Overall given it's 0.5kg lighter, has shallower DoF and takes 82mm filters to me it's a much more practical choice.

Kwick1: But how does it work with adapted Canon lenses?

You get varying stories on the A7R3. Some people have good success with newer lenses and metabones IV/V with latest FW, some get success even with older lenses, some have no luck. It's one of those you have to try it for yourself features with Canon glass.

Would love a 125/150mm f/2.8 Art Macro, but I'm worried weight would balloon. Current 150 f/2/.8 OS is 1kg, as an Art lens it would probably hit 1.5kg.

And despite all their hype about vignetting have a look at the wide open vignetting curve, it's still terrible. SO why make a lens so large to supposedly overcome vignetting and yet it still has bad vignetting and really who cares that much about it other than astro guys.

Stupidly heavy for a teeny bit more performance. 135 f/1.8 looks a much better proposition and will offer as much back ground blur given they have the same 75mm aperture. Hell I bet Canon could offer a 200 f/2 DO that weighs this much.

Doug Pardee: So... they're saying they found a way to transfer 160 MB/s over the 104 MB/s UHS-I bus? Is that for devices with a standard UHS-I interface, or is that why they added the notation "performance may be lower depending on host device interface"?

What devices could make use of this? And wouldn't they probably just support UHS-II instead? (Yes, there's a hardware difference between UHS-I and UHS-II.)

Did you know the Sony A9, A7R3 which support UHS-II cannot write faster than 150MB's despite the cards being able to do 280-300MB/s.

The write speed of that new card is not better than their current best UHS-1, it's just the read speed, which helps for downloading images, but doesn't help the camera write images to the card faster.

thx1138: Impressive specs for the money. Now why oh why didn't the A7RIII get the same AF as the A7III, whihc in many ways is an A9 lite now

The A7R3 has a faster readout speed than the A7III, it's 1/15s uncompressed RAW or 1/30s compressed RAW according to Jim Kasson's tests, which makes sense since it's got 42MP and still does 10fps.

Reaching new heights of absurdity with the lens weights of the Art series. 1.65kg for a god damned 105mm prime. Even the mighty Nikon is only 985g.

What next a 4kg 200 f/2.

Eye AF seemed better on the A7III, it stuck better. It would be more relevant to compare A7III and A7RIII however.

Woodyz: I don't know... I kind of like the barebone charm of my OG Sony A7.

This A7iii is quite a lot of camera with a hefty price tag. Losing a bit of that mojo there.

Everybody wants something for nothing. I'm no Sony fan, but this looks terrific value for the feature set: A9 AF, 10fps, 4K from full sensor then oversampled, tilt screen, BSI sensor, 15 EV DR. What more do you want. You can always buy a 6DII offering a lot less for more, or an APS-C mirrorless.

Almost had me there for a minute. Whilst I expected crop of a crop for 4K (hell D500 has crop of a crop too), I didn't expect lack of DPAF in 4K mode. I suppose if it CDAF is quite quick it might not be a huge deal breaker, but I doubt it'll be any good for anything moving a quickly.

Any idea's Richard how regular CDAF performed in 4K video mode?
