Hopefully it will be much sharper than the Sony RX10-II at the high frame rates - I found the image quality (specifically sharpness) to be highly disappointing at 1,000 fps.

Eric Calabros: "This kind of coating would theoretically help collect enough light to study galaxies with low surface brightness"

Did Canon PR team write this sentence?

Higher contrast. Reflector telescopes have components in the optical path that basically reduce contrast (and other optical artifacts). Refractors don't have these components and produced higher contrast images. Special coatings like Canon uses helps even more. Not quite that simple, but that's the 50,000 ft explanation.
One Q I have is could they not have done the same thing with the Nikon version of the 400/2.8 or were the coatings/light transmission not as good as Canon?

Yep, the winner would not be my choice or even near the top, but that's just me and my particular taste . . .

russbarnes: Interesting. Personally the last thing I'd want is an advert on a camera bag for what's inside. For the same reason I never use branded camera straps either. They look nice nonetheless...

Yeah, just look for the bag with the red dot on it to know what to steal . . .

Yep, my camera bag doesn't look anything like a camera bag for just such a reason.

CF Cards? Make them thinner and get rid of the in-camera pins and you might have a future . . . but not in my A7RII and Pany m43 bodies. Nikon and Canon full frame might carry on using CF cards, but they missed the boat with mirrorless bodies.

Eric Hensel: Looks like great results, unless you take lots of shots with the sun in the center of your images.

Which is what many would indeed use this lens for. Disappointing for sure.

If you want to see how bad this lens flares when pointed into the sun head over to see the pictures here:

Very poor sun stars too . . .

Based on the jpegs, at f/1.4 it's pretty darned sharp across 90% of the frame (far corners a bit smeared), by f/2.8 it appears to be cleaned up all the way out to the far corners. Pretty impressive.

That looks like it just might be luggable up into the mountains! Very cool.

aldosigma: f2.4 for 1400$? now sony can make PR slides with A7R II and this lens vs dlsr and 85mm f1.4 and tell "how compact their mirrorless system really are and its price is also in check"

Since when is max. aperture directly proportional to price of a lens?
Should a crappy-performing f/1.4 cost more than an excellent wide open f/2 lens just because of the extra aperture?

Digimat: i know this is totaly up to personal taste, but the loxia lenses look sexy, clean, an mechanical simple. just as it should be. thoose bulbous batis ones though...uagh.

Love the dust/moisture resistance, no AF motor, solid build, etc. of the Loxias. I just hope this one is excellent wide open optically. Only the 35/2 Loxia is really not very good and I hope Zeiss makes the 85/2.4 excellent across the frame right from wide open.

Now with the most excellent Sony A7 series AF is not a necessity anymore and more and more people are finding out that they can in fact use a MF lens. Plus the design compromises that come with AF lenses can be cast away to focus more on optical excellence.

EvilTed: Sony, can you please fix the single-threaded file writing routine SO THAT IT DOESN'T LOCK EVERYTHING UP.

I learned to write multi-threaded software correctly 20 years ago.
I guess this has been lost to the JavaScript masses :(

That assumes the processor & IO system can indeed handle multiple threads . . .

HowaboutRAW: "Improved stability in picture shooting mode (by optimizing temperature control)"--didn't know firmware could make the body bigger for a bigger heat sink, sarc.

So, like they now turn off the rear LCD lamp during long exposures to save battery and lower temperatures . . . I suspect not.

Also, will the lens focal length I enter into the IBIS menu now show up in EXIF . . . . likely not.

It's like no one at Sony actually USES their cameras so that they can identify easily fixable issues that drive some of us crazy.

Turbguy1: Neat! What's the frame rate? Based on the exhaust plume internal details and ground dust movement, it's really fast.

And I always question: "Why test horizontally when a rocket is used vertically (most of the time)?

For a simple solid rocket motor like this it doesn't make that much difference if you test it horizontally vs. vertically (other rocket types clearly need to be vertical or at least be oriented correctly to the acceleration vector due to liquid propellants, tank dynamics, etc.). Also there's all sorts of other compromises testing at sea level brings besides the effects horizontal vs. vertical.
And JordanAT is totally correct - way way way easier to strap this thing to the ground than try to build a tower that can hold on to something producing ~3M lbf of thrust each . . .

Amazing how many people really don't understand how Kickstarter works. You are an investor if you participate financially in such endeavors with all the attendant risks and rewards. Just like other investments you should do your research first before committing funds to such things.

"Favorable Exponynt
What do you need a chip for? Aren't you a photographer?"

Yes a photographer who likes to be able to make the most of his time and having EXIF and automatically input focal length to IBIS saves me time.

Sorry, Sony E mount, but it doesn't contain a CPU by any of the images that I've been able to find.

falconeyes: I wonder if US citizens are aware of how ridiculous their legal system now looks to other parts of the world?

In my mother tongue, the idea of a "state of justice" is so important that the corresponding term "Rechtsstaat" became a part of other languages too (cf. https://en.wikipedia.org/wiki/Rechtsstaat ).

It is a corner stone of democracy and it is quite obviously (to people living abroad at least) broken in the US.

Especially in our times of competing civilizations (West vs. Arabic vs. East), the broken legal system of the US causes tremenduous damage to all of us.

falconeyes - What does your comment have to do at all with the topic at hand?
