In reply to:

chshooter: Doesn't look that sharp to me. Especially the photo of the terrace towards the end of the series looks quite soft for a shot even at f4. Other shots stopped down don't look much better. Little details are not that clear and detail is everything in landscape photography

Nothing really sharp anywhere in the frame. A9 missed focus a lot of times, none of the action shots were that sharp. Looks consumer grade quality, must have been fairy dust sprinkled on the MTF's. The sunstars are pretty bad too. If you can't get a truly sharp shot on a 24MP FF then you're going to be in a world of pain on the A7RII.

And all that complem­ented by

Samyang 14mm F2.8 AF

Samyang 35mm F2.8 AF

Samyang 50mm F1.4 AF

I think we can say that not many lenses are missing

Ton of lenses missing especially 200mm+. That line is less impressive considering how much duplication their is in some of those FL. Missing lenses:

17/24/(35-45) TS-E
150/(180 or 200 macro)
200 f/2
300/400 f/2.8
500/600/4
800/5.6
200-400 f/4
400 f/4
400 f/5.6
150-600 f/5.6

Line up is solid now in the UWA to medium tele.

bilcobarnes21: I would be really Intreasted to know from any Sony Pro lens users who have previously or along side used traditional SLR brand top end optics how they rate against one another (focus speed, accuracy, performane etc)
Not just responses from fanboys would be nice and probably surprising .

I use the 24-70 f/2.8L II on the 5DsR and the glas is still capable of handli8ng that resolution, the detail I get for landscape shots is amazing. AT this level all these high end lenses are stellar.

Astrotripper: Wow, $2200 for a lens and it's not even weather resistant?

Well the Canon 1 series uses real gaskets around buttons, and can be used in pretty miserable conditions safely and some of their lenses have o-rings around rear moust and when used with filter are fairly moisture resistant, but if it's truly rainign I would use a rainjacket for body and lens no matter how good they claim the sealing, these aren't IP rated devices as Alex says. But Sony cleary offers inferior level of protection compared to the equivalent Canon, the 16-35 L III has seals throughout the lens and is clearly marketed as dust and mositure resistant and costs the same amount.

Richard Kwon: Does this mean that we can't complain about FE mount doesn't have enough lenses anymore??? That's a bummer!

Yeah where's my 300 f.2.8 FE, 400 f/2.8 FE, 500 f/4 FE, 600 f/4 FE, 800 f/5.6 FE, 200-400 f/4 FE, 200 f/2 FE and one budget 150-600 /f4-5.6 FE for a start. Also we need TS-E lenses and some more macros (150-200mm) , then they will have good line-up. They are pretty good below 200mm now, so things have improved greatly.

Krich13: Where can we see its MTF charts?

It doesn't need to be as good as the Canon, it just needs to be as good or better than the SIgma in my opinion. Given the small size I'd happily live with perfomance in the Sigma range, any better is a bonus. UWA are the only real lenses that benefit from mirrorless design, we see huge size and weight advantage in this case.

crsantin: Glad they are adding lenses to the system but I can't afford either one of these lenses. Oh well.

Good to see mroe lenses but alas not the superteles they urgently need, 300/400 f/2.8 and 500 or 600 f/4 need to be out the door befoire years end.

In reply to:

straylightrun: Nice lens. Shame about the typical inflated Sony price though.

Hell I'm no Sony fan boy but that price actually impresses me given how hard these things are to design. If it performs better than the Sigma , I'd buy one when the A7RIII or A9R is released.

But I wonder how they can put so little glass into the design and it still be highly corrected. If it stands up to scrutiny maybe Sigma could learn a thing or two. Their current Art lenses are bordering on ridiculous size and weight.

On article Looking back: Canon's eye-controlled focus (210 comments in total)

Eye controlled AF was a brilliant concept ahead of its time. Why they would drop then technology given the vastly better computing power, image analysis abd ability to track a feature, it would be brilliant addition to a system with a huge AF point count.

Please not only bring that back but launch it in a EOS 3D, we need a 1DXII in a smaller form factor and with more pixels.

In reply to:

citrate: Is there a particular reason why "On-sensor phase detection doesn’t work any darker than F8"?
I remember A9 can autofocus at F11, with phase detection or contrast?

Canon's DPAF works works to f/11, better than the normal PDAF, at least on the newer cameras like 80D, M5, 1DXII, 5D4

"And, AF can function with camera and lens combinations having an f/11 or wider aperture (vs. f/8 with the EOS 80D's conventional AF) - again, using 80% of the frame. "

On article Updated: Sony a9 samples with Raw support (450 comments in total)

dpreview still clinging to outdated ACR for RAW. For high ISO DxO Elite PRIME is hands down best NR engine. Wait until that supports the A9 and it also extracts better detail, has better lens profiles. Only thing it lacks really is local adjustments, not sure why they haven't got on that yet. Otherwise C1 Pro 10 is best overall IMO.

thx1138: Imagine how much better those photos would look if you had used the A7RII.

All joking aside wonderful images and good to see a discussion of the logistics of using such an extreme wide-angle lens and how it can completely change your way of thinking on composition. Only thing holding me back is price. I could go with the Sigma 12-24 but it's not as good, although how much that would matter for real life shooting is debatable.

@ geonyc

Well thought out drivel thanks for the feedback, next time give me advance warning to ignore it before I waste time reading it.

Go ahead and wait 10 years for Sony to try and copy the Canon, it might be released with a 400 f/2.8 FE and 500 f/4 FE just in time for the A9 mk 4 release

So on my Canon's I can set up several registered shooting types and switch to them with either the mere press of a button or turn of a mode dial without lifting eye from the VF, so what's the revolutionary Sony sauce with the A9 that makes the same thing so good? You can assign any settings you like and register them and save them to the C1-C3 slots to instantly recall them. You complain Sony hasn't implemented proper custom mode settings, which Canon and NIkon have, but because it offers an alternative method it's some how much better. How many ways do you want to skin a cat, less is more as they say.

On article Sony a9 Full Review: Mirrorless Redefined (2726 comments in total)
In reply to:

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.
