DominicVII: SmugMug costs money to use. The basic option is 3.99 USD per month. Flickr is dead.

Quality analysis there.

Mortal Lion: Bright for them they mean. I am afraid the future is paid.

You made a point, it was answered, and then you couldn't/wouldn't rebut and so you just changed the topic? Brilliant.

Protogonus1: These pissant 2 x 3 prints are actually about all the typical smartphone FAKE CAMERA is capable of, as we know by experience. Using an iPhone 6, printing 5 x 7 is the absolute limit and even then it shows trace pixels. Why bother? Why waste your precious time on Earth pretending to do PHOTOGRAPHY, which obviously requires a machine made to do the job. If it’s worth photography, it is worth using a real camera.

Jesus Protogonus1, you obviously have absolutely no idea who/what this device is intended for, and yet you feel the need to slam it. Think about things before you post.

CaptainNoddy: Canon is diversifying their products to maintain the profit.

They know that they cannot maintain their market share leader for high end cameras in the future, given that their old tech.

Look at Fujifilm, their main profit is from INSTAX Cameras and Printers, rather than the X-series MILC.

Don't worry rrccad, it was just yet another an excuse to try to slam Canon for having "old tech".

barringtonpro1: Personally I like this, but most people can't tell the difference between cell phone quality chip and medium format quality chip, images. The rules of 1950's format still apply but, too few notice anymore. The "photo drawing true compression" from it's long focal length lenses and short distance must be beautiful.

The window of opportunity with this is maybe, 7 years, serving the uber rich. Wish I could be there.

Tom, you're going to end up going around in circles with people who don't understand the difference between perspective and angle of view.

melgross: Why the specific call-out to Nikon and Sony, and not Canon?

No, not really. Hence my comment.

I don't understand why a short explanation of the various types wasn't included in the "article". Not everyone keeps up to date with all the new formats.

PhozoKozmos: NiSi F3:
FF 36x24 Diagonal AoV Specs
aimed at
old narrower Cine-Aspect-within-36x24 [3:2] Canon-FF-dSLR-format, only? [5DMkII]
and
newer wider Cine-Aspect-(of-38.1x20.1) Canon-FF-DCI-format, too? (C700FF)

_25mm T2.1 = 82° (81.5°)
_35mm T2.0 = 63° (63.2°)?
_50mm T2.0 = 47° (46.6°)
_75mm T2.0 = 32° (32.1°)?
100mm T2.0 = 23.5° (24.3°)?

Canon Cine FF = 38.1x20.1 (FF DCI): Canon FF Primes have wider 43mm+ image circle
Sony CineAlta FF (w/Cine) = DCI crop within 36x24 (like old current FF dvcams)
old
dci: 36x19 = 40.7mm image circle
16:9: 36x20.25 = 41.3mm image circle
2.35: 36x15.3 = 39.1mm image circle

Agreed.

Mistral75: The same five lenses were announced at NAB 2016 by Vincent Huang, CEO of the Taiwanese company Bokkeh, under the name Bokkelux. See for instance http://www.4kshooters.net/2016/05/09/new-bokkelux-cine-prime-lenses/

The Bokkelux lenses were shown again at NAB 2017. Today, this is what one can see when opening http://www.bokkeh.com/

"Hello Everybody, thank you all, the Bokkelux Lens Project is dead. Period."

Since then, these five lenses were also announced by Zhuo Yu (Beijing) Technology Co., Ltd., better known under their ==Kinefinity== trademark, together with their Mavo and Mavo LF cinema cameras:

http://www.kinefinity.com/mavo/

At the time of the announcement, Kinefinity stated that these lenses would be manufactured by Zhuhai ChuanFu Optical Technology Co., Ltd., better known under their ==NiSi== trademark.

Today NiSi are announcing these five lenses on their own account.

Please get a job at DPReview, to fill out these press release copy/paste jobs.

BJL: The absurdity of the anachronistic description "Full Frame" becomes ever clearer. It has meant 36x24mm but sometimes 56x42mm for medium format, and now it apparently also means a 36x20mm video format, according to Canon.

Seriously, it would not be either hard or confusing to start giving the sensor dimensions in mm. Actually, in most cases just the sensor diagonal would be enough: the industry also uses diagonal length in spec sheets as the format "Type", and that one number tells us the image circle size needed.

Film formats are sometimes described this way: often for medium and large formats, and also "36x24" is used for standard 35mm film still camera format in parts of Europe.

And don't get me started on Canon's absurd use of "APS-H" — which was the 30.2×16.7 mm uncropped format of the failed Advanced Photo System film format. Canon's misuse is a different size and a different shape, and almost nobody knows what APS-H was anyway.

Why have 7 people liked BJL's post? Everoyne knows what FF means. It's just a name. Sheesh.

entoman: Looks like it would be incredibly useful to police forces and security services in tracking down criminals and terrorists. Anything that helps to catch these scum-assholes has to be hugely welcomed.

Yeah, because all criminals are immigrants.

ABW: And for those wondering how stills work out with anamorphic lenses on the iPhone - check out this set of pics on my Flickr (link below).

I shot hundreds of pics with the Moondog Labs lens on my iPhone 6 Plus and loved how they turned out. It wasn't just the anamorphic dimensions (full16x9 stills) but the glass was really flattering too.

Obviously I also edited these in post but only on the iPhone. I must admit de-squeezing them was a pain util I found the CropSize app which does batch re-sizing...

I did however later use Photoshop to get the images up to approx 23" x 13" which I printed, framed and sold at an exhibition. All this from an 8MB jpeg out of an iPhone. No its not a 42MP A7RII but it was pretty good.

Indeed, there's so much theoretical rubbbish written here about the number of MP you need to print at size XxY, presumably by people who've never printed anything.

falconeyes: The most stunning thing isn't this algorithm.
Which is plain stunning anyway.

Most stunning is that this isn't the most stunning news coming from NVidia these days. It was real-time raytracing on a Volta graphics card presented at GDC.

As I'm sure you know, he's referring to the Star Wars "Reflections" demo showing a ~$65K DGX station *partially* raytracing a 24gps scene in real-time. It's great to see such improvements, but it's not really relevant for everyday use yet.

In reply to:

noyo: For me, even the best EVFs are poor substitutes for OVFs, which offer the only true 'live view'.

EVFs still suffer from too much latency, plus the 'live view' mechanisms need to close the shutter and re-open to make the exposure. This all adds up to being too slow.

Of course there is the option to use multi-frames per second but that is different to the art of capturing the decisive moment.

It seems to me that the clamour for mirrorless is purely a misguided 'trend' which may win in the end but could make life difficult for people who would prefer to have OVFs by making them harder or more costly to obtain as they get pushed out of fashion.

@noyo:

Regsitering your preferences here is uninteresting, but whatever, that's up to you.

But making false claims about the effectiveness of the technology - claims which are obviously coloured by your preferences - is not.

In reply to:

chida: Every moment of is a celebration of life itself! Can't understand who got this idea of the particular day for a particular subject and wasting energies on such nonsense. This is a very unproductive exercise.

And yet, here you are, along with everyone else, discussing it.

In reply to:

uMad: What the article is missing is, that the X1D has no focal plane shutter. So one has to use the electronic shutter, which is extremely low. This limits the usability quite a bit

Unfortunately it's not an article, it's just a press release. It would be nice if there was some actual editorial commentary to go along with many of these regurgitated press releases.

On article CP+ 2018: Hands-on with Laowa 'Magic Shift Converter' (119 comments in total)
In reply to:

Mike CH: “When used with the converter, the 12mm F2.8 becomes a 17mm equivalent, F4.”
“on a full-frame Sony camera”
That doesn’t make much sense?
Also, shifting any full frame lens +/-10mm *without vignetting* on a full frame camera seems dubious to me.

Thanks Seppo. I wondered about the "slightly tilting the camera body", so your reply clears pretty much everything up. But just to be absolutely sure, the line on page two of this article that says "it also enables a shift movement, to correct for converging verticals" is incorrect (in relation to this adapter, as opposed to true shift lenses)?

Yes, I understand that you're getting an off-centre crop of a wider view.

Essentially, I was asking how a shift lens corrects converging verticals, but instead of being lazy this is my cue to go and do my own reading!

Seppo, yes, I know. But it sounds like you're saying that the shift does nothing to correct the converging verticals?
