Exploring Canon's cinema lens range

Although the Cinema EOS system made its public debut in 2011, Canon's history of cinema lens design can be traced back decades. It began in 1969, when Canon accepted a request to build a cinema zoom for Hollywood filmmakers, and two years later the K5x25 macro zoom lens was born. This was soon followed by the iconic K35 Prime Series, which were recognised with an Academy Award in 1976 and are still appreciated in the industry today.

The latest Canon cine lenses are the culmination of half a century of experience in the construction of cinema lenses. With their combination of outstanding optical performance, class-leading build quality and trusted reliability, Canon's Cine Primes and Cine Zooms are equally at home capturing natural history in HDR as they are on high-end drama sets.

"We've always been known as a wide-ranging imaging company and for many years just as well known for our cine lenses,” says Paul Atkinson, Product Specialist for Professional Video at Canon Europe. "The current range is designed to produce an uncompromising level of image quality, and to do that consistently, day in, day out."

This consistency is one of the key advantages of the Canon cine lens system. Whether you're using a Cine Prime, a Cine Zoom or a Cine Servo Zoom, you can be confident the colour balance will remain the same.

"If you decide to swap the CN-E14mm T3.1 L F Cine Prime for the CN-E30-300mm T2.95-3.7 L S Cine Zoom, for example, you won't see any noticeable colour shift because all our cine lenses are designed to work together," Paul adds.

"There are other shared features, too. The gearing is the same on the lenses, and the front diameters and filter threads on the Cine Primes and Sumire Primes are also identical, making it easy to change lenses without adjusting a rig setup.

"Ultimately it just comes down to finding the lens that's suitable for the look you want, your shooting environment and your budget. The opportunity to choose anything from 14mm right through to 1500mm and know that you're going to get a consistent level of performance gives you incredible flexibility."

To help you make an informed decision as to which Canon cine lens is right for you, here's a guide to the different types of cinema zooms and prime lenses that are currently available.

Canon's Cine Zoom range is separated into two distinct groups of lenses – Top End Cine Zooms and Compact Cine Zooms. Both classes of lens are designed for EF and PL mount Super 35mm cameras and offer outstanding 4K image quality for high-end film productions.

Significantly lighter in weight than zoom lenses covering the same focal length, Canon's Cine Primes feature a durable design and industry-standard controls. A natural fit for high-end productions, the full set of seven full-frame lenses covers a focal length range of 14mm up to 135mm, giving plenty of creative options to professionals who prefer the aesthetic qualities of cine primes. Each lens has been designed with consistent colour reproduction in mind, so there is no noticeable colour shift when swapping between focal lengths.

"These are very sharp, high-contrast lenses with exceptional bokeh," Paul says. "They have the advantage of having a wider T-stop of T1.5 in most cases – even T1.3 with the CN-E50mm T1.3 L F and CN-E85mm T1.3 L F. They also exhibit minimum focus breathing. Sometimes with photography lenses there's a discernible change in the field of view when you change the focus, but that's been significantly reduced across the entire Canon Cine Prime range.

"Because these lenses are designed for EF mount cameras, it means we have compatibility with the Dual Pixel Focus Guide for accurate manual focus assist, plus the ability to transfer lens metadata back into the file. It means that for a camera with Electronic Image Stabilization, such as the Canon EOS C500 Mark II, the camera will automatically detect the focal length and set up the stabilisation correctly when the function is activated."

Engineered to deliver sublime image quality with a noticeably different character to Canon's Cine Primes, the Sumire (pronounced "Soo-mee-ray") collection of full-frame prime lenses lends a more cinematic look to productions.

The Sumire Prime range, including the CN-E20mm T1.5 FP X, CN-E50mm T1.3 FP X and CN-E85mm T1.3 FP X, offers the same seven focal lengths and fast T-stops as the Cine Prime line-up. Both sets of prime lenses also share an identical colour tone, mechanics and construction, with a consistent 300-degree focus travel, 105mm screw-on filter thread and 114mm front diameter for matte boxes.

Where the Sumire Primes differ is that their optical formula produces a more cinematic look with a hint of softness, natural skin tones, subtle flares and rich, silky bokeh. These characteristics are particularly evident at wider apertures, with a smoother focus fall-off. They come with a PL mount that can be converted to EF at any local authorised service facility.

"Although both the Sumire and Cine Prime lenses have 11-blade diaphragms, the bokeh is slightly different with the Sumire lenses, especially towards the edges, where it becomes more elliptical," Paul says. "The Cine Primes have a more universal rendering in this respect."

Blending stunning 4K optical quality with broadcast-friendly features, the trio of Canon Cine Servo lenses offer a versatile choice for broadcast and handheld applications where servo control is required. Available in both EF and PL mount, the lenses are designed for Super 35mm sensors, with the CN10x25 IAS S E1/P1 also offering Full Frame coverage when using the built-in 1.5x extender.

Similar to their larger Cine Servo stablemates, the leaner, lighter Compact Cine Servo zoom lenses are designed for 4K Super 35mm cameras and feature built-in servo control. However, their more compact construction means that they're easy to use handheld or shoulder-mounted on shoots that move at a fast pace.

"These are workhorse lenses for filmmakers who shoot documentaries on a compact cinema camera such as the Canon EOS C200," Paul explains. "Both the CN-E18-80mm T4.4 L IS KAS S and the CN-E70-200mm T4.4 L IS offer the convenience of cine-servo operation in a conveniently small-sized package. They're ideal for the run-and-gun shooter who wants a quality optic without the hassle of having to rig up a bigger lens. For added convenience, you can even program the joystick on the Canon EOS C200's grip to become the zoom controller.

"The maximum aperture of T4.4 is slightly slower than that of other zooms in the Canon cine lens range, but with the performance of today's sensors it's not an issue. The added convenience of precise autofocus, image stabilisation and cinematic optical quality make these lenses highly appealing."

Both of the affordable Compact Cine Servo lenses are stabilised and are offered exclusively in EF mount, so they benefit from three modes of image stabilisation and Canon's accurate and reliable Dual Pixel CMOS AF.
