Are these rays by God?
Or rather by a meteor or a fake alien ship?

Sdaniella: mimicking fake analog optical lens flare?
lol.

ridiculous. as bad as seeing it replicated in non-photographic paintings or graphic illustrations [ditto: fake 'patterned' bokeh of OOF images]

i see it in many modern movies which use CGI animation, even if it is a 'full animation (like the recent: The Croods - 3D, which otherwise all else was visually exquisite to watch), it's just as absurd. why highlight a flaw of analog optics [the bane to any photographer] in a 'digital virtual world' makes absolutely no sense except for it's sentimental 'hey look, we can fake pretending we have a real optical lens involved!' rather than a virtual (mathematically calculated image of a light source (sun, spot-lights, what have you) shining into a 'virtual camera')

next, they'll have 'fake bad sky polarization' effect on wide angle shots, or 'fake digital rainbows', which were so often misapplied INCORRECTLY via optical filters in the film days.

sdyue

:-) I would like to have this, is it possible that they are able to do it?

The ZERO stitching ERROR composition, full resolution and optimized version is ready, I have just posted it here, in 2 versions, one wider and one cropped:

Sebastian Z: After so many months in space, those wheels are so clean...no dust at all, makes you wonder do they have rover washing stations on mars, or that thing just drives in somebody's living room with fake background...

"not dust at all"?
No Sebastian Z.
There is some dust and veil of dust everywhere, and some very little stones too.
Also the MAHLI camera have already some dust on the front lens, not much, but begin to became a little disturbing.

Claudio NC: I have posted my version of this panorama in Flickr, here:

http://www.flickr.com/photos/alpi-costerni/8148100978/in/photostream/lightbox/

I have not had more than 1 hour of time to do this composition, I could have done better using missing shots.
The single shots posted by NASA-JPL have not all the same exposure and there are also abnormal reflections in the upper part of the rover that I have not removed.
But look at the parts of the rover in the lower left.
The stitching defects are much less obvious, you can make the comparison with the NASA version.

I have already seen the SOL 85 images, need really only 1 pict to fill the left side made with SOL 84.
The NASA version have filled that part with another picture, that is not from that location and the color fusion also demonstrate the bad made insertion!

John_Spencer: One remarkable thing that no-one has commented on- there are no foreground/background mismatches due to parallax. That means that the arm was manipulated to point the camera in 55 different directions while keeping the optical center of the camera in the same 3-dimensional location. Quite a technical tour de force! I can never get that right with Photosynth...

Absolutely not true!
Look more carefully the image at full resolution.
There are many stitching errors everywhere, but particulary on the rover itself.
I have already commented this and made my quick verision of this composition in Flickr, yesterday:

bimmerman: Wait a minute, did they say zoom type is extending??? Meaning the length of the lens changes when zoomed??? Oh no!!! say it ain't so Nikon. Why can't they make one like Canon? This is going to be a dust pump!!!

just look at the picture of this lens to understand immediately that it has rotary controls for zoom and focus and therefore is not a pump.
Less exclamation-question points, bimmerman, please use more your eyes and thought control!

On SLR Magic to show four prototype lenses at Photokina article (114 comments in total)
In reply to:

Edmond Leung: I am living in Hong Kong but never heard this brand.
Nowadays, manufacturing industry in Hong Kong is rare. I think it is made in China but the company is registered in Hong Kong.
Don't expect too much from the products made in China.

Hong Kong is already part of China, but the people in Hong Kong (even the people in Mainland China too!) will not buy the products from China if they have money in their pocket.

Hi Bali_Mirage,

obviously here we were not talking about products (electronics, optical, mechanical, etc.) built and only built in China, so built-produced-assembled, according to standards and controls imposed by companies in the rest of the world, this seemed obvious.
The distinction between something like Motorola, HP, Apple, Cosina for Zeiss, etc, etc, etc (on one side) and all Chinese industries, with Chinese engineers and Chinese (copied) know-how (the other side), it should be quite evident in this speech.

In reply to:

Gully Foyle: I'd get a Voigtländer instead.

I have 2 Voigtländer:
28/1,9 Ultron Aspherical_M39
180/4 Apo-Lanthar_PK

The 180mm seem to be very good on all the APS-C frame already at f/4, full open.
The Voigtländer 28mm is good, but not more then good, at least my copy is so.
The Contax Zeiss 28/2.8 is better, give better details (more details and less fuzzy), particullary around the borders of the frame.
Tested on Sony NEX-7 and Olympus OM-D EM-5.

Edmond,
thank you for writing this clarification, I was not aware that people in Hong Kong prefer not buy the products from China, this say a lot.

3 years ago I had purchased, for Sony NEX, a cheap lens marked with this name, right now I do not remember the focal length, maybe it was about 25 ... 30mm, perhaps was f/1.4.

But the build quality was very poor, although new, the blades of the diaphragm, made ​​of gray iron, semi-gloss (so too reflective) were partially already rusted.
The optical performance just as ridiculous, with only the center of the frame, just mediocre, also at f/8.
Was good perhaps to do dreamy images, almost all blurred, but really nothing more, as Jun2, have said here up, a toy lens.
I sent it back and they were sorry that I have not appreciated their lens...

Now this brand seems to be the same, but the quality is like that of one of the most big and famous, really light-years of difference.

On Sony Alpha NEX-5R preview (145 comments in total)
In reply to:

olddutch: The Nex-5N is a marvelous small camera, easy to use and handle. Can make excellent pictures, but not with its standard 18-55mm kitlens. That lens adds an gray haze to all pictures I made with it, and that haze appears very difficult to remove. Therefor I bought a FD-Nex lens adaptor from a china site and now have my first Canon 50mm F1.8 (!) kitlens, a prime from 1976, mounted on the Nex-5N body. The Nex-5N is very well equipped to manually focus this odd combination, which I call my Casonyon camera. The resulting pictures are marvelous and more important: without a haze!
Sony should learn how to make quality lenzes for its Nex camera's!

Take a Canon FD 50/1.4 which is much better than the f /1.8.

The haze you say is not normal, something in your Sony lens is defective.
Take a look if there is haze in the optic using the narrow beam of a strong flashlight.
Look from the front, put the light on the back, close to the lens mount.

Surely Sony will soon learn to make quality lenses, because Zeiss will ask for your precious consultation.

In reply to:

Sosua: Hmmm... these examples are not great.

If you really want an extended DR image, better off getting a Nikon, expose for the highlights then do some moderate shadow pulling.

You won't encounter the dramatic shift in tones to balance our at the edge of light and dark.

I just had a look at your site, sincerely images are really poor, not for landscapes that are obviously beautiful, but the color rendering of the tones too unnatural, areas that are artificially too bright or too saturated and also too desaturated depending on the colors. Ugly shades/nuances.

Really poor, you can easily see, at first glance, right from the small low-resolution previews of the galleries.
To forget.
Excuse me for my criticism, but that's what I think.

In reply to:

ennemkay: hmm, yeah i strongly prefer hdr photography that looks realistic. the extreme form of hdr, as in the havana photo above, is clearly computer-generated to anyone who's looking at it, which puts it in a totally separate category from every other type of photography we generally discuss on these forums. hdr for the sole purpose of increasing dynamic range to eliminate the appearance of highlight and shadow clipping is something i'm far more interested in, personally.

Well said!

In reply to:

gilo: I find all these images pretty uninspiring. What's the nice thing about losing all the shadows and having everything displayed flatly in front of you? It's like when a child plays with the ipad and has fun taking distorted pictures. at the beginning it's fun but at the end he outgrows it. Similarly, I am just waiting for the time digital photography will be finally relegated to mobile phone snapping and real photography will go back to film.

Pretty uninspiring? ...You are too kind.
These are really ugly, almost horrible!

Which definition could we give to something that is the opposite of Fine Art?

In reply to:

Isabel Cutler: Minimum and maximum shutters speeds are reversed.

M Jesper,

shutter speed is shutter speed.
Is not only "speed" (that is an old word, commonly used, near to a no sense, or if you prefer, with a mystification sense, in other words, a bad technical definition, when used for a lens, but here is for a camera).

Jsabel Cutler, of course is right, and the values are obviously inverted.

Also write "Articulated LCD . . . Fixed" is a really stupid label.

Hooray!

I understand you correctly?
Nikon and Sigma have created a new super Foveon camera, cannibalizing parts from D4, SD1 and SD1 Merrill and mixing the firmware?
How much... 108MP?

JoeDaBassPlayer: Focus Peaking is a must for a mirrorless camera. IBIS would be good as well.

The Focus Peaking is a welcome and promising function, but in the NEX-5N and NEX-7 unfortunately is very inaccurate.
I say this because I'm using both these cameras with manual lenses.

What seems at perfect focus looking at the coloured markings in all the frame, almost always (by checking with the zoom of live-view) is a lot out of focus and then you must correct each time.
Given this there is little surprising that some autofocus too often fail in their intent, I think that the logic function is the same, or similar.
With the autofocus mode, an electric motor is actuated, with focus peaking, the informations are overlayed on the live view monitor.

Pena_lva, no hate from me, just discomfort and big irritation, hate is in you!

I like the rough bulls, strong and insensible when I see them in their natural habitat, but out of the pen, in an environment like this are misplaced: they are adding their crap-merda production, good only to fertilize their closed, confused minds, with deficient expression and personality with lack of self-critics, (expressão deficiente e personalidade com falta de auto-críticos) already too many like you in the world, probably no need for more.

we can not see a proper name misspelled, please spend a few seconds of your time double reading before posting.
Rubbish as Aplle, Cannon, etc., is best left in his own interior and not cause suffering to millions of readers, thank you!
