Canon, Nikon and Sony Prosumer Full-Frame DSLR

Introduction:

The full-frame DSLR market heated - by the end of the three major suppliers, Canon and Sony prosumer DSLR Nikon full-frame 's all in the market, all at a similar price.

DSLR

The 12.1 megapixel Nikon D700, D300 is based on proven technology from both the Nikon D3 and Nikon was announced in July, in the far and is already available. With an original MSRP of $ 2,999.95, only three months after its announcementStreet prices have already fallen to the $ 2,750 mark.

Rumor months, 24.6 megapixel Sony Alpha A900 has been finally announced officially from 2,999.95 on September 9 with an MSRP of $ and the few weeks it should be available in the next.

A few days later, Canon announced the Canon 21.1 megapixel Canon EOS 5D Mark II offers a comprehensive feature very serious, and the addition of 1080p HD video, while lower than both the Nikon and Sony with its $ 2,699.99 MSRP. L 'Camera should ship later this year.

Three very different cameras, all at a price very similar to DSLR to do an interesting choice for the consumer or Professional with a maximum of $ 3,000 to spend on a prosumer.

Nikon D700

The Nikon D700 is the excellent Nikon D3 sensor in a body like the Nikon D300. With the optional MB-D10 battery pack (which also fits the Nikon D300), the D700 can achieve impressive 8fps, while recording 14-bit file, at least until the buffer fills up.

High ISO performance is excellent on the D700, like the Nikon D3. The Nikon D700 is also proven to autofocus and measurement. However, the camera resolution is lower in the group, only 12 megapixels, and off a lot of potential buyers.

Canon EOS 5D Mark II:

The 21.1-megapixel sensor has a resolution similar to the flagship Canon EOS 1Ds Mark III, but has aMuch broader ISO performance. In fact, exceeds the ISO range, the Nikon D3 and D700 at ISO 50 to 25.600 (vs ISO 100 to 25.600 for the Nikon).

The sensor of the 5D Mark II is a year younger than the sensor of the D700, and if eligible low-light capabilities, including the Nikon D700 is near, then Canon has a very impressive camera in his hands with a much higher resolution on the Nikon. There are a couple of sample photos floating round of the Canon, so it is too early to be sure, but the Canonhas huge potential - we will soon see much difference does a year of development of the sensor.

The big news is the Canon HD 1080p video mode. For many, this feature is a gimmick is the best, but for some this is a very powerful tool - the ability to provide a considerable range of high-quality lenses, the use and control of depth of field, which simply does not exist on cameras consumer price of the video today. This is a great advantage for some, and a nice to have formany.

Sony Alpha A900:

The Sony has the highest resolution of the three cameras, but fails in two main areas: the ISO performance is considerably smaller than its main competitors, and it offers only 12-bit A / D conversion For the vast majority of shooters, the 12-bit A / D will not make any difference if very realistic. The problem is more in perception, a full frame camera is almost $ 3,000 should be 14-bit A / D conversion to dateMarket.

Comparing the cameras:

Driving in a new luxury car, and your neighbor asks the first question: "How much HP has this thing for" With the cameras, but Megapixel - right or wrong, this is the most important selling point for the average consumer, with the ISO function is a very close second.

In reality, very few photographers need more than 12 megapixels. If you are the Web-publishing is usually 3 megapixels more than adequate - mylarge 1920 x 1200 monitor is about 2.3 megapixels. A 1080p HD-TV is less than 2.1 megapixels.

Most prints are high quality printing with 300 dpi (dots per inch), 150 dpi prints still look very good. At 300 dpi, an 8x10 photo requires a little more than 7 megapixels. A 16x20 print at 150 dpi requires 7.2 megapixels. how many people who buy these cameras go beyond print?

The main advantage of more megapixels is the ability to harvest. This is especially useful for nature,Sports and nature photographers who need to reach as much as possible. What is important for their pixel density - the more "pixels on target" you can get with your lens longer, more intimate and can be more effective you'll get. But none of these cameras have the highest pixel density is - if you want to achieve, it will be better served with a Nikon D300 or the new Canon 50D. Information on the same pixel density Canon 50D in a full-frame sensor, you would need a camera with full framenearly 40 megapixels.

Like it or not, the attribute of the camera that makes the headlines, the number of megapixels. From a marketing perspective, the Nikon D700 brings a great disadvantage to the Canon 5D Mark II On paper, Canon also wins the race ISO, but only now. Until the camera out on the market, we will not know for sure how good his performance is low ISO. The Canon also has 1080p video, as I said, is a key point of salefor some, and irrelevant to others.

Where the Canon beats the Nikon, it is almost everything else has: it has a higher maximum frame rate (especially if you buy the MB-D10 8fps pack that adds more than double the fee), and on paper, but also a superior AF system and measurement system. In the same way that most horses is useless if the car can not be made ready to go out on the road (eg transmission, suspension, tires, traction control), the Nikon D700 is still avery interesting package, especially for those who shoot sports or action.

The megapixel Sony A900 won the race, but the Canon is very close behind. However, he will lose bad when you factor in the ISO performance. Canon also has a much wider range of high-quality lenses to back up the camera and offers 14-bit A / D conversion 12-bit Sony on picture quality for those verses. It also has video support, and is about 10% less, so that effectively makes the Sony CanonA900 is a non-starter for most people.

Then back to Nikon vs. Canon. Both companies have a wide range of professional quality lenses and accessories to attach the camera. The Nikon is an ideal choice for sports shooters. The landscape photographer or studio is available on the higher resolution of Canon lean. If the ISO performance proves to be similar for the Nikon D700 and Canon 5D Mark II, then for the wedding photographer and photojournalist who, Low-light capabilities, the Canon is the extra resolution that give you the edge. If this means they simply do not have to do with image files larger (has more space on your memory card to load more, more time to process mail, etc.).

For everyone else should satisfy both the Nikon or Canon or more of their needs, but the marketing advantage of Canon Law. If you've spent a lot of time shooting in public, then you know that someoneto get rid of you at some point and say, "nice camera, how many megapixels is that thing?"
