There are a lot of anecdotes on the net that are frequently regurgitated on forums by people who dislike the push/pull design, however most of them are unfounded and based on speculation.įirst off, the good stuff. From a price/performance standpoint, it packs a LOT into a relatively easy to handle package, offering the benefit of a zoom and the bulk of L-series quality (lacking only wide-open sharpness at the long end.) This is a fairly old lens design.over a decade, if I remember correctly. Therefore, the example ( pictured) of UV0512 means the lens was made in the Utsunomiya, Japan factory in May 2007.If your interest is wildlife, as someone who photographs wildlife and birds myself and uses this very lens, the Canon EF 100-400mm f/4.5-5.6 L IS is the lens you want. The last two digits are for internal Canon use. The next two digits represent the month the lens was manufactured. The second letter, 'V', represents the year of manufacture The first letter, 'U', represents the factory that made the lens. On the back of Canon lenses is a six-digit code, which indicates where the lens was manufactured and when. ( March 2020) ( Learn how and when to remove this template message)

Super-telephoto lenses such as the EF 500mm f/4L IS USM, or the EF 200mm f/2L IS USM have a rear 52mm drop-in filter holder which can be used to hold gelatin type filters.Īccording to Canon, its L series lenses are Some telephoto L-lenses, such as the EF 70-200mm zoom lenses, or the EF 300mm f/4L IS USM do not have rear gelatin filter holders. Wide angle L-lenses typically have a gelatin filter holder on the mounting collar of the lens, which allows a gelatin to be installed behind the lens. Larger sized L-lenses, such as the 70–200 mm, 100–400 mm zooms, and longer focal length primes (300 mm+), usually have an off-white barrel to reduce heat absorption under the sun that may otherwise affect the performance of the lens.

All current L-series lenses have ultrasonic autofocus motors (USM) and extra communication pins, except for the specialist tilt-shift lenses which do not provide auto focus.Ī gelatin filter holder, on the rear of an EF lens. Standard prime lenses have a much greater maximum aperture, such as Canon's current 50mm and 85mm L lenses which open to f/1.2. L lenses are often 'fast', with maximum apertures commonly f/2.8 or f/4, and, with the exception of the RF 100–500 mm f/4.5–7.1L IS USM lens, never exceeding f/5.6. Their front elements do not rotate for the proper operation of some filters, such as circular polarizers. L lenses also contain optics of higher quality, with many lenses containing aspherically ground, fluorite or ultra-low dispersion glass elements. L lenses tend to be more durable, incorporating dust and water-resistant rubber seals on some models. Most L series lenses share a number of common characteristics not found in Canon's line of lower-end lenses. Some models of L lenses utilize an infrared reflective heat shield coating. Canon L series lenses have a red ring around the lens barrel and the letter 'L'.
