In other words Boston Dynamics is going to start working on flying robots.

chadley_chad: I know the location well … it’s one that, however sharp your lens and good your camera, images always come out a little ‘fuddy’ as I call it. It’s all the water in the air!

Get closer and the air won’t matter as much.

Marquee: Great to see some Peak District Images on DPR. I would say though, that particularly for the images taken from Bamford Edge (#1 and #4), its hard to understand if you intended the whole scene to be in focus or just some foreground edge rock detail. The 50MP sensor really demands some focus stacking if you intended the former. As for DR modes, why not just bracket! I find a lot of these gizmos are just a distraction from the parameters that really matter.

“ There is no such thing as a still landscape in the U.K.” is an intriguing thought but what does it mean?
Has England suffered an outbreak of earthquakes?

ProfHankD: The "Sunny 16" rule was made before significant global dimming -- https://en.wikipedia.org/wiki/Global_dimming. We are probably closer to "Sunny 15" now on average, and in cities where airborne particulate pollution is in high concentration, it can be more like "Sunny 11" or worse. The interesting thing is, I wouldn't be surprised if the pandemic has brought us closer to being back at "Sunny 16."

Hank: I was just reading an old piece on the Stanford website summarizing research on smog and UV radiation done in 1973 and 1987. “Both found reductions of UV radiation ranging from 22 to 46 percent.” Visible light was only cut 6 to 7 percent.
Anecdotally having grown up in the LA basin the skin-burning potential of the LA sun seems much higher since stringent smog controls were enacted.

I have an inkling that the reason both the sony and sigma show focus breathing is that it’s an expensive problem to solve.
Non-breathing 35mm cinema lenses like the Canon CN-E 35mm T1.5 start at $3500 and go up steeply from there.

The bokeh has a nice swirl to it that adds an appealing dynamism to the photographs.

When I saw the photo of the person holding the camera to their face my first thought was “how smart, he’s made a face harness to keep his camera ready at eye level!”
But then I figured out it was just a mask. Why is reality always so disappointing?

(unknown member): There is a very small group of photographer who need a 1.2 lens.
There is an even smaller group of photographer who need full resolution in the corners at F/1.2.
There are many who are able, but not willing to spend more than 2k US$ for a 50mm prime lens.
Good news: Buy a 150 US$ 50mm/1.4 Nikkor from the 80ies and make the same, if not better images (no joke).

On the topic of rendering doctor, with your unique set of measuring instruments and formidable brain have you solved the mystery of what makes a lens able to capture depth cues that produce a trompe l’oeil illusion? (notice how I didn’t say 3-D?)

probert500: Well you can't enhance resolution in PP - so if you want dreamy, smear vaseline on a filter over really sharp lens.

Give up a stop or 2, boost your ISO and you can have a nice small simple lens. I use my $60 50mm 2.8 zuiko om macro for copy work, and it is awesome. Weird irony that, with the ability to change ISO with a push of a button, everyone wants a superfast lens. oy

Outstanding meeting of lens and subject.

A friend of mine has one of those and let me use it; I 100% agree, it’s a lens that makes beautiful images.

Istina: I owned for two years a sigma 50mm ART and used in in like a hundred of jobs. Beside the bad focusing, optically it's always been "perfect" but very, very flat. I ended up selling it in favor of the canon EF 50mm 1.2. For a period I owned them both and I shot landscape and portraits with both lenses, and sigma is way, way flatter, doesn't perceive as much nuances like the canon, neither colors are as good. All the shades of blue of the sea were one greyish tone with the sigma, with the canon you could see all of them. Portraits with the Canon are worlds apart from the flat colored and toned sigma. I'm sorry but the new designs can be "sharp and perfect" but they just answer to the new bs amateur that looks pictures at 200% and charts all day. If the price to pay to have a perfectly corrected lens is having way heavier lenses and flatter images I'd rather have a non perfect lens but with an outstanding depth. There's a reason if Canon 50mm 1.2 is still very expensive on used market

Don’t project your poor color discrimination onto others. Just be happy there’s someone else out there helping to keep the photo industry alive.

Not a fair comparison, some of those Olympus lenses were far ahead of their time.

Dreamscape Photo: Do you think it will have a Leica mount? to capture the high quality of the sensor? LOL

That seems like a pretty simple mod using whatever design software. Or an X-acto and some CA glue.

Beolab: Am I supposed to buy this camera without knowing the sensor size?

Yes because sensor size doesn’t matter, that’s a lie promulgated by a small group of fifth columnists trying to destroy photography. The only things that matter are lenses, technique, and creativity.

Wil Helm: Does it record 4k? No, joke aside. I am sorry, thats only 2m for a whole set of such important pictures. Paintings achieve much higher values. Imagine a set of the very first paintings ever painted would be sold for just 2m. That would never happen.

Could I interest you in buying a share of the Caves of Lascaux? Vet exclusive, very hush hush.
