Canon EF 17-40mm f/4.0 L USM Lens Review. Because it is a very high quality but moderately-priced ultra wide angle zoom lens, the Canon EF 17-40mm f/4 L USM Lens is one of Canon's best selling lenses. The 17-40 f/4 L fills out the bottom focal length range of Canon's f/4 L zoom lens series. It is the lightest L lens currently made (1.1 lbs / 475g) and is the smallest L zoom lens currently produced (3.3" x 3.8" / 83.5mm x 96.8mm - DxL).
As indicated by the "ultra wide angle" designation, the 17-40mm focal length is ultra wide on a full-frame DSLR. Let's take a look at a focal length comparison. I know, the 30mm focal length is a somewhat unusual choice for this comparison, but ... Utilizing Ring USM, the Canon EF 17-40mm f/4 L USM Lens focuses very fast, quietly and accurately. Wide open center of the frame sharpness ranges from great on the wide end to good on the long end. The 17-40 L resists flare very well. A 7-blade circular aperture delivers excellent OOF (Out of Focus) blur quality. This is an easy-to-take-with-you lens. Canon EF 24-105mm f/4 L IS USM Lens Review. Boasting the superb build, mechanical and optical quality found in the Canon L-Series Lenses and a widely used range of focal lengths, the Canon EF 24-105mm f/4L IS USM Lens is one of the best and most popular Canon general purpose lenses made.
The 24-105 L Lens quickly became one of my favorite and most-used lenses. If I had only one lens, this would be the one. One of the most important features in a lens is the focal length or focal length range - get it wrong and you might not be able to take the shots you want. And the use for a particular focal length or focal length range varies, of course, depending on the FOVCF of the body being used. That said, this lens gives us a very nice general purpose focal range to work with. On a full frame body, 24mm is very wide. On a 1.6x body, 24mm is only moderately wide (equivalent of 38.4mm).

Review based on a production EOS 5D Mark II with firmware 1.0.7 August 2009 - Updated to reflect the additional manual control over video exposure introduced with firmware 1.10.
Back in August 2005 Canon 'defined a new DSLR category' (their words) with the EOS 5D. Unlike any previous 'full frame' sensor camera, the 5D was the first with a compact body (i.e. not having an integral vertical grip) and has since then proved to be very popular, perhaps because if you wanted a full frame DSLR to use with your Canon lenses and you didn't want the chunky EOS-1D style body then the EOS 5D has been your only choice. Three years on and two competitors have turned up in the shape of the Nikon D700 and Sony DSLR-A900, and Canon clearly believes it's time for a refresh. So here is the 5D Mark II, which punches high in terms of both resolution and features, headlining: 21 megapixels, 1080p video, 3.0" VGA LCD, Live view, higher capacity battery.

Review based on a production Canon EOS 7D, firmware v1.0.9 Canon's X0D series was, for many years, essentially the default choice for keen enthusiasts, professionals and aspiring-professionals who wanted top-level image quality and functionality without the bulk (or price) of a pro-level camera such as the 1D series. The 10D, 20D and 30D were hugely successful and popular cameras, and you didn't have to spend long shooting with them to understand why. However, like every other sector of the DSLR market, there are some very competitive rivals, in terms of both price and features. Cameras such as Sony's A700 and Nikon's D200 and 300 have meant the most recent X0D EOSs have been held to higher standards and have found it a little harder to stand-out.
Which brings us to the 7D, a camera that seems determined to wrestle back the king of APS-C crown. Key features Show all listings (13) ...

Imaging Resource rating: 5.0 out of 5.0 Canon 5D Mark II Overview Reviewed by Shawn Barnett, Dave Etchells, and Zig Weidelich Review Date: 01/20/2009 The Canon EOS-5D Mark II raises the standards of the entire EOS line, as it is the first EOS digital SLR camera to offer both still and video capture.
Its upgrades are welcome, because though the Canon 5D leads the race for overall image quality for many photographers, it lags behind in a few key areas, most of which improve with the 5D Mark II.

Want to learn more? Suggestion for improvement? Head over here. Nikon D3X Overview by Michael R. In 2007, Nikon offered pro photographers a new option for full-frame digital photography (and a chance to make their old Nikon glass fully usable again): the Nikon D3 digital SLR.
For its first full-frame digital SLR, Nikon took a balanced approach with a camera that offered excellent overall performance, but didn't significantly raise the bar in resolution. Nikon's D3X isn't a one-trick pony though -- there's a lot more to this camera than just resolution. Befitting its flagship status and market-leading resolution, Nikon has set launch pricing for the Nikon D3X digital SLR at $7,999.95, the same price at which Canon launched its 21.1-megapixel EOS-1Ds Mark III a little over a year ago.
