The Canon EF 70-200mm f/2.8L IS II USM Telephoto Zoom Lens is the bomb in the telephoto class of lenses. This hefty lens weighs in at 3.3 pounds and is 7.8 by 3.5 inches without the tripod collar. This is a stationary glass lens meaning it doesn’t telescope out or moves when focusing or zooming, it is done internally. Externally it has two rubber grip rings with the zoom ring being closest to the base or the camera. It is marked with 70, 100, 135 and 200 mm. The second rubber grip is for manual focus. Due to the hefty weight of this lens it works best used on a tripod.
This Canon lens uses an ultrasonic motor to operate. Externally there are several switches and tweeks that can be made. A limiter switch allows you to choose between full or limited focus range from 2.5 meters to infinity. A stabilizer switch is included that can be enabled or change the mode between one and two. The difference is one is for stationary shots while two is designed for motion shots like sports activity.
All this tech talk needs to be broken down to layman terms. A 70-200mm lens gives you the same amount of lens filling experience if an object is 15 feet away (this is the 70mm) or 150 feet away (200 mm). These are the numbers you are looking for when choosing a zoom lens to determine length and quality of the zoom feature.
The f/2.8 refers to F-Stop, a feature of how much light a lens allows into the camera. It is like the opening of an eye, the smaller the number the wider the eye opens and the higher the number the eye is more squinted. The Canon EF 70-200mm f/2.8L IS II USM Telephoto Zoom Lens excels in this arena with the f/2.8. The ability to let in a lot of light allows for sharp clear pics even when fully zoomed. An added bonus to the Canon EF 70-200mm is the sweet bokeh, or photographer talk for background blur. It keeps the subject crisp with a delightful blur that if so sought in photography.
The optical performance of the Canon EF 70-200mm f/2.8L IS II USM Telephoto Zoom Lens exquisite at all ranges with only a slight barrel distortion at 70mm. This gives straight lines a bit of a curve which is not noticeable in action shots but in landscapes or architectural shots where lines are critical you will notice the wobble but it is easily corrected in post processing. This was the only minor complaint about this lens.
This is a lens that becomes a workhorse of a professional photographer for its short and zoom telephoto range. The MSRP of this lens is as hefty as the lens itself at $2,499.00. Those who make a living with their photos won’t hesitate to spend this money because it is worth every penny in the crispness side to side and top to bottom in the entire frame throughout the entire zoom range.
