- Six "F" Low Dispersion (FLD), two Special Low Dispersion (SLD) elements, and five aspherical elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy. Also, increased control over sagittal coma flare yields high resolution across the entire frame.
- In addition to superior optical performance, the five aspherical elements contribute to the lens' compact build with their thin, highly polarized construction.
- The bright, f/2.8 aperture and rounded 11-blade diaphragm produce a large, beautiful bokeh effect.
- Super multilayer and nano porous coatings have been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
- The lens was also designed to suppress focus breathing as the angle of view changes across the zoom range, creating natural-looking focus pulls when recording video.
- The introduction of a linear motor high-response linear actuator (HLA) to drive the autofocus yields focusing speeds more than three times faster than its predecessor.
- At the wide-angle end of the zoom range, the minimum focusing distance improves to 6.7" with a maximum magnification of 1:2.7 to suit working with close-up subjects or in tight spaces.
- Maintaining the same number of lens elements, the overall length has been shortened to 4.8" while the weight has been reduced to 1.6 lb.
- The aperture ring features both click and lock switches for improved handling during use.
- The robust internal structure features metal parts for the zoom extension, while the exterior boasts rubber seals in the mount to protect the lens from dust and moisture.
- Two integrated AF-L buttons can be programmed to adjust various shooting settings and the lens also features a dedicated AF/MF switch and a zoom lock switch to prevent the barrel from accidentally extended.
The 128GB Professional 2000x UHS-II SDXC Memory Card (2-Pack) from Lexar features a storage capacity of 128GB per card and takes advantage of the UHS-II bus to support advanced DSLR functions such as continuous shutter bursts and rapid shooting, as well as raw and JPEG captures. These cards are also well-suited for video capture, including 4K, 3D, and Full HD video, and can achieve maximum read speeds of up to 300 MB/s and maximum write speeds of up to 260 MB/s. Thanks to their V90 speed class rating, minimum write speeds are guaranteed not to drop below 90 MB/s, making it qualified for use with cameras that include the Blackmagic Pocket 6K G2 and Ursa G2.
UHS-II cards achieve their speed through an extra row of pins, and while these cards have been designed for cameras that are UHS-II / V90 compatible, they may be used in devices that do not support UHS-II / V90. However, bear in mind that these cards will then default to your device's speed class and bus rating, such as UHS-II and V60, which supports minimum write speeds of 60 MB/s, UHS-II and V30, which supports minimum write speeds of 30 MB/s, or UHS-I and U3, which also supports minimum write speeds of 30 MB/s. If your device does not support U3, these cards are compatible with the U1 and Class 10 standards, each of which guarantee minimum write speeds of 10 MB/s.
As with most Lexar media, these memory cards are able to withstand temperatures from -13 to 185°F, allowing you to take them with you into extreme environments, such as snow and deserts. Should the cards become compromised, users in the Americas will benefit from a limited lifetime warranty, while those in Germany and regions not recognizing the lifetime warranty will benefit from a limited 10-year warranty.
