William Heaton, the Wetpixel.com moderator has posted a comprehensive review of the Ikelite eTTL 2 housing with Canon EOS-5D digital SLR William says that the Canon EOS 5D truly is a revolutionary camera. The EOS 5D cuts the price of full frame digital SLR camera by more than half. This will enable many more people to use it, whereas this kind of camera was previously limited to working pros and extremely wealthy hobbyists. The only other full frame digital camera is the Canon 1DS Mark II which sells for $8000.

Heaton has thoroughly reviewed the Ikelite eTTL 2 Housing for use of the Canon EOS-5D as a Scuba Diving Camera. Ikelite is already addressing the negative points Heaton brought up in his review. Here’s an excerpt of what William Heaton says about the Ikelite eTTL 2 housing with Canon EOS-5D digital SLR:

After diving with the camera/housing I can say with confidence that I am going to love this camera and housing. Although I could not use my fisheye, I was able to use my 28mm f/2.8.  While this lens would not be very wide on a crop factor camera.  On the 5D it was sufficiently wide to have some fun.

I have never taken any "great" shots on the first day with a new piece of equipment.  Well today everything - the camera, housing, lens, strobes, and strobe arms was new.  Diving with a new kit is just too much fun to take good res.  That said, I am happy with what I got.  I can see the potential. 

CNET has reviews from 15 users of the “Canon EOS 5D. The Average user rating is 8.3 out of 10. The editor of CNET gives the Digital camera a rating of 7.9 out of 10. After reading the reviews, it seems that for it’s price, the Canon EOS 5D has an unexceptional set of features. Here is part of the CNET editor’s review of the Canon EOS 5D Digital Camera

For some photographers, a sensor the same size as a frame of 35mm film (24mm by 36mm)–often referred to as full frame–is the Holy Grail of digital SLR technology. It promises the familiar shooting experience in viewfinder size, in lens angle of view, and in certain aspects of a picture’s look. Until now, this object of lust was available only at great expense ($7,000 or more) or in cameras with significant design and performance quirks. But Canon’s EOS 5D changes that, combining a 12.8-megapixel, 23.9mm-by-35.8mm CMOS sensor with a competent midsize SLR body for less than half the price of the only full-frame alternative available at this writing, also a Canon, the EOS-1Ds Mark II.

The Canon EOS 5D’s design and performance are only fair, and its feature set is unexceptional for the price. But its high-resolution images offer superb detail, rich tonality, and incredibly low noise. If image quality is your paramount concern, or you’re one of those full-frame nuts–er, aficionados–then buy this camera, and you’ve just saved 4,000 bucks.
