Review of the Canon wide angle lens – The EF-S 10-22mm F 3.5-4.5 USM
I have just received my new Canon EF-S 10-22 ultra-wide angle lens. This is one of Canon’s most popular lens and is designed for the “crop sensor” series of DSLR. More on what a crop sensor is later. The question of the day is why do I need a 10-22mm wide angle lens. I already have a EF-S 18-55 zoom that came with Canon X1i camera. So what am I going to do with that extra 8mm of width for a wide angle shot. There is a great need for those of us that shoot landscapes for a wide angle lens. I have been shooting most of my landscapes at 18mm with my kit lens on the T1i. That means that I am shooting at 28.8mm in film 35mm size. Now I have to explain the crop sensor stuff. Suffice to say that there are three ratios of crop sensors in the Canon line of cameras; full sensor, 1.3x, and 1.6x. The full sensor is the same size as the 35mm camera of years past. For practical purposes this means that the full sensor would see the entire football field, the 1.3x sensor would see inside the 20 yard lines and the 1.6 factor would capture inside the 30 yard lines. Here is a list showing what Canon cameras have which sensor:

Canon EOS 1Ds, Mark II and II (Full Frame)
Canon EOS 5D and 5D, Mark II (Full Frame)
Canon EOS 1D, Mark III,IV (1.3x Crop Frame)
Canon Digital Rebel, T1i,XSi,XS (1.6x Crop Frame)
Canon EOS 20D,30D,40D,50D,7D (1.6x Crop Frame)
You will also know that the 10mm, the widest of the wide angle, is really a 16mm on my camera compared to how it looks on a full frame camera. What about the other characteristics of the lens? Canon designates their top-of-the-line lenses with the letter “L” in the description. Although the EF-S 10-22 f/3.5-4.5 does not carry the “L” designation, the use of three aspheric elements and one SD element is a common characteristic of a quality lens. This has quality optical parts and is not a “low-end, consumer type lens”. The EF-S design allows the rear element to be closer to the sensor then with EF lenses, improving image quality, especially at the shortest focal lengths. There are many technical reasons that this lens is good for wide shots and landscapes.

Canon wide angle lens – A Perfect Lens For a Stunning Photo
Photography has come a long way, thanks to the technological advancements brought forward by camera manufacturers. One of the more popular camera brands is Canon. There are various factors that need to be considered when buying a camera, particularly the Single Lens Reflex cameras. While most consumers would prefer a camera with high megapixels, enthusiasts would be busy arguing which lenses to use. A case in point would be the Canon Wide Angle Lens.

Canon Wide Angle Lens is ideal if you specialize in portraits and landscapes; but that’s not to say it wouldn’t work as well in other specializations. Most Canon lenses have built in stabilizer motor which helps if you do not have a tripod at hand. There’s the price, the focal range, and the durability factor.
