ALC & Adorama.TV: First Look: Canon New EF 70-200mm f/2.8L & f/4L Lenses
Let’s start off with the lens whose predecessor I personally have in my arsenal: the new 70-200mm f/2.8L. The Series II was already my go-to lens for dark wedding ceremonies, studio headshots, and for getting a beautifully compressed wedding portrait. Now, Canon has gone ahead and added Air Sphere Coating (ASC) to help cut down on sun flare and ghosting, particularly in backlit situations like the ones below. Pair that with the already wildly necessary image stabilization and crystal clear image quality and this lens is sure to be a staple in your camera bag…..
EF 70–200mm f/2.8L IS III USM
The EF 70–200mm f/2.8L IS III USM lens features an incredibly bright zoom with an f/2.8 maximum aperture that stays constant throughout the zoom range. The EF 70–200mm f/2.8L IS III USM’s bright image even enhances AF performance, sending more light to more areas of the AF sensor to help facilitate a faster, more accurate focus. Combined with its 8-blade circular aperture, the EF 70–200mm f/2.8L IS III USM lens is engineered to capture dramatic images with gorgeous background blur.
Canon’s Air Sphere Coating (ASC) Minimizes Ghosting and Flare.
The addition of Canon’s Air Sphere Coating (ASC) enhances the EF 70–200mm f/2.8L IS III USM lens’s ability to suppress reflections. ASC helps combat aberrations regardless of focal length or the angle of light. This helps provide cleaner photographs with fewer distracting reflective effects in the image.
Reducing Smears and Fingerprints
To help maintain a clean lens, even after multiple lens changes in sub-optimal conditions, the EF 70–200mm f/2.8L IS III USM lens has a specially designed fluorine coating on its front and rear surfaces. This fluorine coating helps prevent dust, water, oil and other surface residue like fingerprints from sticking to the lens, which facilitates quick and easy wiping, without the use of solvents.
Optical Image Stabilization
For consistently sharp results, the EF 70–200mm f/2.8L IS III USM lens features an Optical Image Stabilizer system that provides shake reduction for up to 3.5 shutter speed stops*. This helps provide reliable handheld performance and clear image detail in low-light situations or at lower ISOs.
* Based on CIPA (Camera & Imaging Products Association) standards. Testing performed at a focal length of 200mm using the EOS-1D X Mark II digital SLR camera.
Minimum Focusing Distance
With a minimum focusing distance of approx. 3.9 ft./1.2m, the EF 70–200mm f/2.8L IS III USM lens helps enable operation close to the subject, perfect for intimate portraits, headshots and detail work. For instance, at its minimum focus distance and zoomed to 200mm, the maximum magnification is 0.21x, meaning you can fill the frame with a subject 6.7 x 4.5 in. (approx. 170 x 114mm) in size.The EF 70–200mm f/2.8L IS III USM lens offers complete manual focusing, even when AF is engaged, with a simple twist of the lens’s focus ring. Additionally, full-time manual focus means you can achieve and maintain focus manually, which can be especially handy when shooting video or composing still images on an SLR camera’s screen.Befitting Canon’s L-series lenses, the EF 70–200mm f/2.8L IS III USM lens features a superb optical formula for high-resolution, high-contrast images throughout its zoom range. It consists of 23 lens elements in 19 groups, including one fluorite and five Ultra Dispersion (UD) elements. The result? A lens of great clarity and fidelity that helps render sharp, beautifully detailed images with minimal distortion
