Excellent Optical Design

The Extender RF1.4x achieves both high image quality and a smaller size with an 7 elements in 4 groups optical design that utilizes the large diameter mount and short back focus of the RF mount. By adopting the latest high-refraction, low-dispersion glass, curvature of field and chromatic aberration of magnification are suppressed for the highest possible image quality. It also features an optimized lens coating and three-cemented lenses to reduce ghosting. This makes it possible to take advantage of the high image quality of the master RF super telephoto lens.

Three cemented Lenses

 

The three cemented lens in the Extender RF1.4x reduces the air contact surface as much as possible, thus effectively reduce ghosting that tends to occur with extenders.

Slim Design


Thanks to the RF mount, Extender RF1.4x can now use a slim design that reduces the length of the extender to 20.3mm after mounting to master lens.


High Precision AF

The Extender RF1.4x has built-in microprocessor for lens communication, high precision AF1 can be achieved with Dual Pixel CMOS AF (DAF) in EOS R series camera.
