The Canon EOS 5D Mark II Escalates Full-Frame Digital SLR Photography to the Next Level with HD Movie Recording Capabilities, DIGIC 4 Imaging Processor, and 21.1 Megapixel Resolution

Canon EOS 5D Mark II - Performance:

Canon, the first company to introduce a full-frame digital camera, has improved the EOS 5D Mark II Digital SLR camera's newly developed full-frame CMOS image sensor. Utilizing proprietary Canon technology, the Company has reduced noise and expanded the sensitivity of the CMOS sensor up to ISO 25600, which is three full stops higher than the ISO 3200 limit of the original EOS 5D camera. Although the individual pixel dimensions of the EOS 5D Mark II camera are the same as the 21.1-megapixel CMOS sensor used in the EOS-1Ds Mark III digital SLR, the new sensor incorporates an improved output amplifier and a more advanced color filter that improves light transmission while retaining excellent color reproduction. By applying the same kind of advancements in sensor design and image processing technology as the recently introduced EOS 50D camera, but at higher resolution and with larger pixels, the EOS 5D Mark II achieves the highest level of image quality of any EOS Digital SLR released to date.

It’s been awhile since the iPhone 3GS was released and at the time many people thought that it was somewhat of a low-key upgrade from the iPhone 3G, certainly it was more of an evolution than a revolution.

iPhone 3GS - Improved Performance:

Everything that runs on the iPhone 3GS can run on the iPhone 3G, but the 3GS is significantly faster. I was skeptical when Apple decided to concentrate on speed rather than introduce new features to the previous iPhone.

When looking at the specs, the CPU in the 3GS is clocked at 600MHz, compared to 400MHz on the previous generation. As well as this, you’ll be getting 256MB RAM compared to 128MB in the 3G. When you’re using the 3GS it feels a lot more responsive, and the speed at which applications load is staggeringly quick compared to what you’d get on the older generation.

Anticipation for 1D Mark III was great and when the word finally came out we saw a camera that was completely redesigned, with new features like improved AF, sensor cleaning, Live View, AF micro adjustment, new user interface, bigger LCD, internal Speedlite control, lighter weight, 14 bit A/D conversion, less noise, more metering sensors... in short, expectations were met and in many parts exceeded. Before the camera was shipped its AF was praised by PR documentation and videos, we got videos showing 10fps in action and how Live View looked.

Canon EOS 1Ds Mark III - Design & Build:

Mark III weight (with battery) has dropped 295 grams which is just what was needed to make a difference. Main weight reduction came from smaller and lighter battery, some internals were done with magnesium instead of aluminum die cast. The body feels as durable and well constructed as all 1D's have felt.

Buttons have been relocated, some removed and some added. The whole layout is simpler for daily use. There is a new AF/ON button which starts AF, but I really like to use the old * button for that function. AF/ON is located somewhat "behind corner" and I found using it disturbed my shooting balance a bit. A great thing is that 580 EX II and Mark III create a weather sealed combination.
