mosc: 50 lines per mm from a 36x24mm sensor is 1800x1200 = 2.16 MP. Did somebody miss a zero there? They saying 500 lines per MM? That's 216 MP.

18:40 time in the announcement video.

50 lines is a specific MTF readout. It describes how high the contrast between the lines at this spatial frequency is, not resolution!

On article What difference does it make? Sony uncompressed Raw (618 comments in total)
In reply to:

Francis Carver: If it is wholly uncompressed, it is obviously "RAW." So, "uncompressed RAW" is sort of redundant.

@ Francis Carver: RAW is not a synonym for uncompressed or lossless (all three categories are independent) but rather for unPROCESSED...
I didn´t get the point of your statement at all: " If it is UNcompressed -- why is it RAW? How about just this: "uncompressed."HINT: JPEG is NOT UNcompressed."
I guess you´re still confusing things:
RAW is ONE thing.
Compression is ONE thing.
Lossless is ONE thing.

Compressed and lossless is NOT necessarily contradictive!
The LZW compression on TIFF-files for example IS lossless...

forpetessake: Every company (modulo Olympus) is going to release FF cameras. The falling prices of the sensors and electronic parts are pushing the market in that direction. We'll eventually see all sorts of FF cameras -- compact and large, cheap and expensive, with fixed and interchangeable mount.
Despite what the uneducated people believe, the size-weight characteristics of the lenses aren't significantly affected by the bigger sensor.

@forpetessake
I just can´t believe that your statements are anything but a joke...

In reply to:

ealvarez: Is this manual focus lens? $599? I can get 135mm f2L canon for about $600 used and Nikon 180 f2.8D even cheaper used.. I don't share much of the enthusiasm. Maybe I would if I was Sony E-mount shooter.

@e_alain:
I guess you maybe confounded which row belongs to which lens?
The Canon is always in the same row where the f-number is placed....

@le_alain:
What makes you think so? I don´t see any contradictions here?

Another thing is that the Canon 135 L looks so weak at the center at 2.0. I used to own one and it never showed results that bad...
Maybe one should ask the cui bono question - who did the test, why and for whom?

You wrote:" It clearly shows Canon winning across the board, especially at the edges."
You might want to see an ophtalmologist before it´s too late?
The Samyang clearly won in EVERY respect except light fall-off at infinity!

In reply to:

bawbaw: Also... to follow up my last comment.... is this guy a bit stupid? He used 2 flash units with X and Y etc .. whereas he could have used continuous light sources instead of expensive broncolour heads and packs. Although... it's a crappy article and badly executed.. so it stands to reason it's over engineered for no reason.

@bawbaw:

1.) At about f18, required for sufficcient DOF, and a suffifient shutter speed, you NEED flash, unless you want to roast your subject using two 6000 Watts movie flooders.

2.) A ring light is bound to be moving with the camera/lens. And since camera/lens DOES move here you will get very weird and inconsistent lighting/shadows with a rig like that!

3.) Epileptic issues at a flash frequency of about 1-2 Hz?? You must be kidding!

They did not deliver resolutions THAT high but the difference is only by quantity, not quality, thus no substantial innovation here. Flogging a dead horse - no matter if the creator was aware of Thomas Ruff´s work or not.

BUT:
There (if intended) is a remarkable suspense and ambiguity in
the notion that a ROBOT acts upon the absurdly exact DEFINITION of a human being. This (to me) feels new and exciting. There is resonance (of what ever).
So the message may not be found in the picture as a result but in the PROCESS of it`s formation AND the result as a whole.

IF it WAS intended as such - Which I seriously doubt - considering the profession and core competences of that guy: doing repro business and maybe just working out a marketing gimmick to gain publicity...

Pt. 2

Marcel Duchamp´s ready mades are not willingly designed by himself but are still entitled to be considered art because HE, not the pissoir, has something to say. The pissoir is a symbol of a message, loaded by the author´s concept, not the message itself. Beauty here (or illumination, if so) lies in the message created by AN ASSIGNER, not in the pissoir.
To close the circle: The "lighting" (pissoir) may not be "beautiful", but the concept may be enlightening.

ad b.)
Sustantial art is bound to push the envelope.
You are in hard luck if you happen to invent a thing that existed for decades. In this case you nevertheless are not an epigonic but a true inventor. But are you a genius? Maybe not! Because, at least in art, relevant inventions correspond to the TIME they react upon. Coming back to the portraits in discussion: Thomas Ruff et al. have eaten the topic (descriptive approach&lighting, hyperrealism, seriality) up about 20 years ago!

Dedicated to craw, CraigArnold , Ken Johnes: My 50 cents (Do they say so? My English isn´t native either)

Pt. 1:

Is it art?
I might know if at least I had information about the following:
a.) Is it INTENDED to be art at all?
b.) If intended: is the creator aware of and reflecting contemporary discourses or is he just a silly tech-nerd?

ad a.)
My definition is based on the assumption that nothing can be art that is not intended to be art. Let me explain my view:

A necessary (but not sufficient) requirement for art is a converging dialog between the creator`s intention and the recipient´s perception. Even if an artist`s concept is to NOT let you know what is intended ((exactly)), and as a result you then DO NOT know IN THE WAY THE ARTIST WANTED you to NOT know - you may call this a converging dialog.

In reply to:

PeterLHughes: There is a much easier and cheaper way. Shoot transparency film with a 5"x4" bellows camera. Scan that single shot at 4,000 ppi and it will give you a 320 MP image. Your shutter speed of 1/125th sec with studio flash means that your model can have expression rather than having to hold a death like pose for half an hour. Also if you look closely at the samples in the review above you can see stitching errors which are unacceptable for professional work. If 320 MP doesn't impress you, then get hold of a 10"x8" film camera. That will give you 1,280 MP images. In other words a 300 dpi print would be 11ft high. I've just checked on ebay and you can pick up all the camera kit you need for under £1,000.

it`s just that the lenses on a 8x10 won`t deliver 300ppi - by far not.
And focus stacking would be necessary anyway (too shallow DOF even at f 45, where diffraction already knocks at the door...)

zsedcft: If he wanted a technical, super high resolution photo - why didn't he focus stack? What good is a 900MP photo if 600MP of it is blurred. It is not like the shallow depth of field has helped much artistically. At least he got some good press from it.

Oh he DID focus stack! At least for the pictures I examined - where nosetips are perfectly in focus too. Maybe a little too few steps though...

sfnikon: Face porn - you get to see every hair follicle, eye vessels up close in geographic detail.
My D800E paired with the Zeiss 100/2 makro already does this too well in 1/500th of a second so this 30 min sitting is not practical it's an extreme art form.

who ever maintained that this method was "practical"?

yabokkie: people should not try to capture the same with one shot which is very difficult if possible, which has physical limitation, medium format or large format or whatever.

the right way to have high quality still is video,
the way that our God designed us.

REPLY B, Pt. 4

There may also well be an increase of 8k 3D video in the future, since it also adds another level of information to the depiction (time). But it will not, because it CANNOT, replace 2D photography. Probably (but some cineasts will say no) it can replace 2D video (8k no doubt is a good thing, be it 2D or 3D, and WILL be the future - for video that is).

8k video might also be THE way to extract a lot of 2D photography stills in the future since it will allow to choose the "right moment" afterwards (sports, weddings, portrait, events...)
So (8k, 3D) video will surely establish a common way and a powerful method to get your desired STILLS - not necessarily to only get your VIDEO. It will be a means to the end of getting stills - as a quality of it`s own.

The final, absolute, ultimate way to resemble "live" human visual experience is not 8k 3D video - it`s the HOLODECK from Star Trek!!

REPLY B, Pt. 3

Paintings did not become obsolete after photography was invented, just like photography did not become obsolete by film or video - and this is not because video resolution used to lag behind - it`s because these are DIFFERENT things!

The unique quality of a 2D photograph is
a.) that it represents ONE moment in time (depicted by an instant automatic process, called exposure - long time exposures aside).
b.) that it is FLAT. Thus allowing the artist to establish a DEFINED composition. It´s about the art of dividing a plane into areas to create harmony or tensions -just like in paintings.

There may well be an increase of stereoscopic photography in the future, since it adds another level of information to the depiction (resembling presence of depth). But it will not, because it CANNOT, replace 2D photography.

2.)
The robot arm moving around here is NOT intended to resemble the dynamic process of human visual perception - it is just a means to an end - to get a STILL image. If he had a 900Mpx sensor plus a corresponding lens, he surely wouldn´t want to do it that cumbersome way (intended show effects aside). Hence his intention is NOT to show the "future of photography" as based on dynamic video-like perception to resemble eye-like scanning (as you constantly claim in your numerous "replies" on posts that don`t even roughly deal with "your" topic).
(By the way this claim is erroneous anyway, as I showed in my other reply A)

Wrong because:

The future of photography is NOT video. Not even 8k video, and not even 8k stereoscopic video.
The future of photography is photography. Since it is an art form in it`s own right. Like painting is.
