On Otus Readings: the Zeiss 85 F1.4 Otus Comparison article (202 comments in total)
In reply to:

mosc: There's some great unsaid conclusions here about the importance of focal accuracy at ever-growing effective resolutions. It seems the DSLR's independent AF sensor might run out of resolution (due to insufficient focus accuracy) long before it's lenses or sensor.

It's nice to be able to look at the absolute resolutions possible with these cameras and also what they're capable of with some very affordable glass too. Very revealing piece that does more than talk about one camera. I wish dpr did more like this, very informative.

I did some tests with my D800 and after careful autofocus fine-tuning the accuracy difference between the phase and the contrast focus was insignificant (20 shots each did not show an advantage to either focus technology). I used FocalPro to confirm that.

Yet in field I have more trust in the contrast autofocus because it does not have those outliers that the phase focus something shows. (Maybe they did not show up in my test because the test target was too easy.)

Regardless of the technology I think that the higher the pixel density raises the more will we have to revert to manual focus in order to squeeze out the maximum resolution and make sure that the focus is exactly where we want it to be.

Yeah! Finally the 85 f/1.4 Art we were all drooling... ohh wait... err... wat?
These aren't the droids you're looking for.

On Canon EOS 5DS R added to studio test scene comparison article (518 comments in total)

The IQ180 is absolutely mind-boggling. I guess you get what you pay for.

In fact even the "low-resolution" D810 and 5DS R images are stressing the studio scene. Most of the component are actually more or less obsolete as they are outresolved by those sensors. The banknote and the etching are still very helpful but with 60MP FF sensors around the corner, the sudio scene might need an overhaul.

I own a full Nikon system so generally I am biased favorably towards Nikon, but this interview is so streamlined and clinical that I feel it is close to offending. (Not DPR's fault at all! After all you only can ask questions.)

This is what an interview should be like:

Open, honest and clear! Kudos to Kazuto Yamaki-sama!

On Lensbaby introduces Velvet 56mm f/1.6 article (166 comments in total)
In reply to:

OliverGlass: Looking good. It's nice to have options and I like this lens. I do have a nitpick:

Was the amount of hard sell marketing language in the script necessary?
"I don't know what it is about this lens that makes me so emotional, but when I opened this photo up on my desktop it made me cry..." is a sample

Last time I cried whan opening a picture up on my computer was when I totally messed up a supposed-to-be-great shot...

On Olympus OM-D E-M5 II Review preview (811 comments in total)
In reply to:

Tapper123: Perhaps the metallic awards system should be done away with? It just leads to contention. Seems the numerical scores are enough, not to mention the conclusion text, for people looking for a summation.

Personally I thought this was a fair review, and I own an EM5 II and enjoy it. Pair it with some really good lenses and it's as good as almost anything except for perhaps some extreme situations where a 35mm sensor has an advantage. I see it as a great all-arounder, a camera that does everything reasonably well, with world class IS, solid build and weather resistance. If you can't get a good image from this camera paired with a good lens, then I suspect the problem is not the camera.

Anyway, gold, silver -- it doesn't matter. It's a great camera, capable of great images, and has a remarkable lens selection. Enjoy it.

How about using different kinds of sea cucumber?

Wouldn't it be totally awesome to see people arguing about why camera A got a Bohadschia argus award while camera B got the Benthodytes award? Oh, the drama!!! The enjoyment!

In reply to:

RichRMA: Ergonomics means nothing, when compared to performance. People will put up with some real horrors. A sharp-edged machined aluminum cube would sell if you could have resolution like a medium format 80mp Phase camera and the noise control of this Sony 12mp.

Give me that cube! Now!

On New samples from the Sigma 24mm F1.4 DG HSM Art lens article (230 comments in total)
In reply to:

King of Song: The public is very fickle. We photographer's never expected too much from Sigma. It was always just a cheap 3rd party lens. Suddenly, Sigma does something extraordinary and comes out with the 35 1.4 Art, and blows away both Canon and Nikon versions. We all rally behind Sigma, because the unexpected underdog becomes the hero.

On the other hand, we photographer's expect monumental achievements from say Canon. Canon just announced a 5fps, 50MP camera. There are thousands of negative posts on this site regarding that camera not meeting expectations. Even if the camera woke up in the morning and cooked breakfast, some would complain the eggs were too hard.

If Canon just put out the exact same lens as Sigma, a 24 1.4 for $849, nobody would have anything nice to say.

I still hope that Canon can fix the egg-to-hard issue with a firmware patch.

PhotoKhan: Oh boy...these guys can't win, can they?
If they do, it's because they do, if they don't is because they don't...

Give them a rest (...if for nothing else, because they're probably still jet-lagged :) ) the way, if you can't do a general appraisal of the lens performance, after having being informed what is used with for the provided samples, I suggest you shoot more and "analyze" less.

In the meantime I can help you out: This is a most excellent lens, the full excellence of which, will be clarified with more formal evaluations.

You missed the fact that most posters here are highly experienced and renowned optical engineers! Each of them at least designed a distortion free 8mm f/1.2 prime with no corner CA wide open, a razor sharp 10-500mm f/1.8 pancake not to mention the legendary nuctulox 50mm f/0.8. They declined Sigmas extremely well endowed job offers over and over again because creating a trivial thing like a 24mm f/1.4 is just no challenge for them.

These images have been made under less than optimal conditions with a less than optimal camera for a wide angle lens and with no lens profile correction going on. A 24mm lens will have CA in the corners. Some of this CA will be LCA, some will be TCA (that can be corrected). But still, thanks to DPR for these shots!
Let's wait for images taken on a D810 with a proper lens profile.
