Canon EF-S 10-22mm f/3.5-4.5 USM Lens Review. With framing equivalent to a 16-35mm zoom on a full frame body, the Canon EF-S 10-22mm f/3.5-4.5 USM Lens provides EF-S compatible camera body owners with the ultra-wide angle focal lengths so often missed on this small-sensor format camera. EF-S is Canon's moniker for Small Image Circle. The distance between the film (sensor) plane and the rear of the lens is shorter than it is in an EF lens. Many have questioned the longevity of this standard, but, my expectation is that it will be around for a long time - easily long enough for most people to get their desired value from a lens.
That is a palomino quarter horse bathed in sweet light from the setting sun. The horse is doing what it does best - grazing. This 10mm capture was made with a Canon EOS 70D. Since the ultra wide angle focal lengths are one of the most-desired features of the Canon EF-S 10-22mm f/3.5-4.5 USM Lens, let's take a look at a focal length comparison. Wide open (especially at 10mm), the 10-22 shows strong vignetting. Canon EF-S 10-22mm f/3.5-4.5 USM. The Canon EF-S 10-22mm f/3.5-4.5 USM is a wide angle zoom lens for Canon EOD digital SLR cameras. This lens is designed with latest technologies to make it highly competitive on the market. The optical quality is impressive and keeping up with the qualities of the L series of Canon. It has the ring-type ultra sonic monitoring focusing that is known to be almost noiseless and quite fast. It is light in weight which every photographer is looking for in a lens.
The speed of the lens is moderate, not fast. It certainly hard to argue with experience, but, a lot of experienced photographers give this lens too many compliments. The Canon EF-S 10-22mm f/3.5-4.5 USM is a must-have in photography for its wide-angle. Canon EF 70-200mm f/4.0 L USM Lens Review. The Canon EF 70-200mm f/4 L USM Lens is arguably Canon's best value "L" Lens, combining professional grade build and optical qualities.
Though solidly built, the 70-200 f/4 L is relatively light (25 oz / 705g). Actually it is very light and small compared to the much more substantial Canon EF 70-200 f/2.8 L Lens or the Canon EF 70-200mm f/2.8 L IS II USM Lens. This lens is not a burden to carry for long periods of time but has a high quality, solid feel. At 3" (76mm) in diameter, the 70-200 f/4 is relatively narrow for its 6.8" (172mm) length. I more frequently use larger diameter lenses, so this is one of the 70-200 f/4's instantly recognized features for me personally. Pictured above from left to right are the Canon 24-70mm f/2.8 L USM Lens, the Canon 70-200mm f/4 L USM Lens and the Canon EF 70-200mm f/2.8 L IS USM Lens. Results from the Canon EF 70-200mm f/4 L USM Lens will make you smile when reviewing at 100% on a monitor.
