A new, better photo of the sought-after Canon EF 11-24mm f/4L USM lens has been leaked on the web along with more information about the wide-angle optic, which will be announced on February 6.
Some would say that it is still a surprise that Canon has not taken the wraps off of the EF 11-24mm f/4L USM lens until now.
Now, it is time for a new set of leaks. Another Canon EF 11-24mm f/4L USM lens photo has been revealed along with details about its construction and its internal design.
New Canon EF 11-24mm f/4L USM lens photo and details leaked on the web
The source is reporting that this is a ultra-wide-angle zoom lens with a constant maximum aperture throughout its focal range designed for DSLR cameras with full frame image sensors.
It will be a weathersealed optic, meaning that it will be resistant to dust and water droplets, therefore it will be aimed at higher-end shooters.
It is said that the product will employ three coatings. The first is a Subwavelength Structure Coating, an anti-reflective technology that reduces flare and ghosting.
The second is an Air Sphere Coating, which is also aimed at minimizing reflections. As a result, flare and ghosting will be reduced even further. This coating was introduced in late 2014 with the new EF 100-400mm f/4.5-5.6L IS II USM
The third and last is a fluorine coating, which is applied to the front and rear lens elements. This coating acts as a repellent to water, dirt, and dust.
Canon focused on image quality rather than price, weight, and size
The internal design of the lens is quite complex, the source says. The optic will include a large-diameter grinding aspherical element and a large-diameter glass aspherical lens.
In addition, a couple of glass aspherical elements will be added along with a Super UD element and a UD element.
The company has decided to focus on image quality. As a result, the lens could be quite big, quite heavy, and quite expensive. A previous source has said that it will be priced somewhere around $3,000.
From the leaked Canon EF 11-24mm f/4L USM lens photo it is impossible to tell how big and heavy the product is. However, the optic will become official on February 6 alongside the 5Ds and EOS M3 cameras among others.
