DanielFjall: This lens is only going to increase in value.

Agreed, value couldn't be any lower, it can only increase.

mick232: Wow, Zeiss gives us a 135/2.8! If this were 1950, I'd be impressed.

No, but my 135/1.8 is.

fyngyrz: Lossy image saving methods are fairly described as "image damaging methodologies."

Other than use as thumbnails.... ugh.

No. Modern media wouldn't be possible without it. Video compression in satellite TV and streaming is also lossy and based on similar algorithms. There simply wouldn't be any Netflix, YouTube or HDTV if non-lossy compression had to be used.

falconeyes: Guetzli is named according to the #GoogleSwissMade series.
It is from the Lab Google Research Europe, located in Zürich, Switzerland and employs 2000 people, the largest Google lab outside the US. It is planned to be grown to 5000 people.

Just a little background info for the kind readers wondering about the name which is Schwizerdütsch actually.

P.S.
Albeit smaller (350 people), the more famous US research lab in Zürich is IBM set up in 1956. It produced one Nobel price.

P.S.2
I'd really liked DPR staff to provide that kind of complementary info. It is easy enough to find ...

And how is that relevant? You did not explain what the word means.

daleeight: No significant loss of quality? How about loss of color or other? The image on the left shows a little green bar for the highlight near the bottom of the eye, and the Google one has no green tint. So what else does it do different? Yeah, it is a tiny area, but it is a difference.

That is why they actually say 'no significant loss of quality'.

TheDarmok74: The obvious question being if they Put it in the S8.

I think the answer is at least as obvious as the question.

In reply to:

keepreal: IMO Sigma would have done better to produce a smaller aperture version up to Art standards, but weighing in at no more than about 600 gm and costing half as much.

Unlike goactive, I sold off my D300 and bought a D610, keeping the full frame lenses I had bought while still using film. I also bought the AF-S Nikkor 20mm f/1.8G ED as I mostly like to shoot landscapes very wide. Had a suitable shorter focal length lens been available, I probably would have bough that instead. Perhaps the Irix 15mm would have done.

I will be keeping my Sigma 12-24mm F4.5-5.6 EX DG HSM Mk I. Testing it on the D610 last week I found that it was even across the frame and was already performing close to its optimum even at full aperture. Mine is quite sharp and has negligible distortion. On the D300 it was only so-so.

Manufacturer presents new lens X - someone says lens Y should have been presented instead. This is probably the billionth occurrence of that.

GRUBERND: it's nice how the speed _CURVE_ in the graphics tries to reflect the reality of such standards, all talking about theoretical limits (remember "USB2: Up to 480Mb/s"?) which hardly any device ever reaches even under lab conditions.
although i dont think that was the real intention behind it. ;-)

What else should they show? Real-world devices don't exist yet and anyway would always just show one specific sample.

HaroldC3: Next up, 1000 kamakaze drones. How would you stop them all?

Send strong jamming signal on drone control frequency.

solarider: Shot from another angle. Impressive, it must have been all computer controlled.

I wonder what happens if someone sends a strong jamming signal on the frequency used to control the drones.

Greg Gebhardt: Kinda shows how China is getting way ahead of us. All the wonders in the world are no longer here.

But only if it's about making existing things bigger, higher, etc.

84% - can any camera actually score lower than that or have we just seen the lower bound of dpreview scores?

In reply to:

xoda: does the lack of any mention of "megapixels" for the 14mm suggest that it's performance may lag behind the 24-70 and 135mm? Those latter two lenses were mentioned as being specifically for high megapixels

Cropping is more likely in a shot taken at longer focal lengths.

It shows at what price lenses can be made available. Margins of other vendors must be huge.

In reply to:

gurgeh: Something I didn't fully understand: for this to work well does it mean you always need the focus point to be at the centre of the image?

What happens if you are focussing closer to the edge, will the focus point become darker and/or blurred? And what would happen to the out of focus part of the image in the centre?

I don't think the position of the focus point is directly related to the path the light ray takes through the APD element,

Otherwise, why would a single light source in the center of the frame show up as an image circle with light falloff at the outer regions?

According to your theory, the discs at the center of the frame would show up as bright, and get darker as they move towards the edge of the frame.

felix from the suburbs: I am a long time Sony A mount user. While I like the A mount, I must admit that Sony has done so little to promote the mount over the last few years that the only likely purchasers for the A99ii are existing A mount users. And existing A mount users, interested in full frame, will buy the A99ii regardless of the DPR review and non-A mount users won't buy it regardless how wonderful any review might be. So, to some extent, the DPR review is rather pointless as far as changing any minds. That is unless Sony actually start throwing some marketing muscle behind the A mount.

Remember: nobody was ever fired for buying IBM (and CaNikon is the IBM of photography).

BRWAT, no doubt the A99ii is a capable camera, but I doubt it's enough to change the game.

NemanRa: "Sony JPEG color is displeasing"
Hmm, The Camera store TV have found that Sony colours are "the most real" and the closest to the human vision. On the other hand, "more pleasing" color cameras are way more unnatural. So, it is all personal preferences. In my view, it is MUCH better to have "true colours" out of the camera and then tweak the photos in whatever way you want to...
Regards

That's funny, because if I shoot something yellow with my Sony, it actually shows as yellow in the final JPG, not as green.

So how come your "unnamed collaborator" can prove that yellows show up clustered in the green regions?
