iTogi 2004: Digital SLR Camera (part2)

написано в рубрике: News — admin @ 9:52

It is reasonable to expect values of tests, rather typical 8-12 Megapixels.
The accuracy of AD conversion and RAW falya – 14 bits, twice the number of sensors will lead to larger raw files, and potentially more recording time, but we hope that the quality difference is worth it.

Moreover, portrait, studio and landscape photography, vyigryvayuschieF80 such opportunities most of all, not so choosy of the standard modes and speed of information processing chamber.
Whatever the case may be, is available as a file record with a resolution of 12 megapixels, and with a resolution of 6 – when the pairs of sensors are combined.
Interestingly, there are several simulate the dynamic and tonal characteristics of the film profiles the data in the camera, you can choose from the menu.
In the new matrix, I want to note two display on the rear wall of the chamber (in addition to the standard upper display style F80).
The lower LCD is designed to display images, the top is a small monochrome LCD matrix and is capable of not only display a variety of digital shooting parameters, but also show the different text and symbolic menu for more options or features over the already captured images.
Thus, color display can be practically integrated into the shooting or the camera settings, he only needed to view the footage.
The viewfinder on the basis of the limited area under Crop factor vidosikatelya F80 at first glance no better and no worse than the D70.
On the other hand, positive emotions is an integrated vertical grip.
Power has its pluses and minuses – the four AA batteries or a rechargeable battery.
Another interesting feature – a sight on the display, like “nonspecular” digital cameras.
Its meaning is questionable – the display does not rotate, but can be justified in shooting from the floor level or vice versa, when the camera over your head.
This raises the mirror and opens the shutter, and then the screen starts to continuously broadcast the image with the matrix.
The possibility that could ever be useful, but which should not be abused – for such a regime is probable cause (potentially) for the dust on the matrix.

Burst speed to 2.
5 frames per second, is ISO 100, but no color matrix metering as in the latest models including the Nikon D70.
Well, only the first tests will show how the image quality to adequately price of this, of course, soundly executed apparatus.
In fact, the second version, the work on the bugs SD9.
Several delayed and not completely done – not likely that this camera is worthy of attention – her only advantage – 3-layer sensor from FOVEON severely limited by ISO – even the value of 400 looks bad and loud, almost like 1600 or even 3200 on the D70 (!
Since part of the photographic camera can not be called successful, and comfortable too.
Lack of support JPG at a leisurely record does not look the best combination.
The appearance of the 20D nullifies the advantage of the matrix FOVEON a real transfer of small parts.
In addition, native Sigma mount holds significant difficulties with the choice and availability of optics.

Above-average
Faster, higher, stronger.
The new, more improved version of the 1D, now – 8 megapixels.
And this is without loss of speed (! ) Burst compared with the previous version of the camera.
And with a larger buffer, accommodating up to 40 (20 RAW, and a half times more than before), the values of ISO 100 or even 50 (via the menu).
Removed the external sensor white balance – apparently without it possible to obtain the necessary results.
Added support for FAT 32 cards memory and support for SD cards (used to be only CF), appeared orientation sensor, resolution 2-inch LCD has risen to 2,000,000 pixels.
The actual resolution is still somewhat less than full-frame (but very expensive 1Ds) but suppress the noise once again improved markedly.
The greatest advantage of this camera – universality.
Reporter’s design and speed, and studio quality at 8 megapixels, low noise level and Crop factor of 1.
All this costs ~ $ 4100 – excellent, thought-out combination.
The only more or less noticeable disadvantage – it is tangible, not an instantaneous launch.
However, removing the report, such a camera, with a generous battery can be kept constantly activated.
We can safely recommend this camera as a perfect option for professionals of any plan.

Canon EOS 1Ds Mark II
The new version of the most expensive SLR camera Canon – EOS 1Ds.
Full frame matrix, now 16 million pixels, increased up to 4 frames per second consecutive shooting, plus all the other innovations that are already familiar from 1D Mark II.
Image quality without compromise, the noise is even lower than its predecessor.
Confused one – the price is still high – about $ 7000.
Full frame and did not become profitable.
There is no doubt that most buyers have enough and 8 megapixels in the performance 1D Mark II, especially given the price difference.
And those who were not enough, can think and inexpensive digital backdrop to the medium-format camera.
However, in the middle is a definite niche for this device, though apparently not so big.
With regards to any other, except for the price, aspects of the work, then this camera is worthy only of praise.
This camera is very close sister D2h, essentially differing only in the matrix and the associated electronics.
In some ways – a competitor 1Ds Mark II, although the price is slightly different niche, perhaps this camera will cost ~ $ 5500, but it can and more (with one side not full-frame Matrix lowers the price to almost the level of D2h other hand, is willing Nikon is do).
APS matrix (1. 5x) with 12 million pixels – today is a record density among all cameras in this article.
Hence, the likely high level of noise (800 ISO maximum setting) compared with D2h matrix which has only 4 million sensors in the same physical size.
The photographic equivalent of the D2h, at full resolution is achieved at 5 frames per second and 8 frames in a special “cut off” at the edges of 6 megapixel mode.
