Our lens and accessory guide for Sony Alpha a7 III Mirrorless Digital Camera rounds up the essential gear that delivers added support and functionality to an already impressive camera.

In this video, I take a detailed look at the Tilta Nucleus-M lens control system. This low-cost system has been hotly anticipated, and I finally got to have some hands-on time with the production-ready model.

ZEISS has just announced a new chapter in cinema optics: the Supreme Primes. These full format, large image circle primes build on ZEISS's deep experience in cinema lenses and provide a modern, yet classic, platform that looks to combine the best aspects of classic Super Speeds as well as modern Ultra and Master Primes. Initial availability is scheduled for this fall. Let's dive in and take a closer look at this exciting new option for top-tier full format cameras like the ARRI ALEXA LF, Canon C700 FF, RED MONSTRO, and Sony VENICE.

The PLx Extenders have been designed for AbelCine by IB/E Optics to be compatible with a wide range of PL-mount lenses. This chart lists zoom and prime lenses that have been tested with the PLx2, PLx1.4 and PLx1.4 Mark II. Keep in mind that if the maximum aperture of a lens is greater than the maximum input aperture of an adapter it will need to be stopped down to achieve a usable image.

Recently, I had the opportunity to test the new PLx1.4 Mark II extender from IB/E Optics. Just like the Mark I, it extends the focal length of your lens by 1.4x, and only loses one stop of light in the process. It also has an image circle of up to 34.5mm, which means it can resolve up to 6K, on the RED EPIC DRAGON for example.

Schneider has pushed ND filter technology forward with their line of Full Spectrum ND filters. As the name implies, these ND filters take into account the full spectrum of possible IR contamination. Previously, ND filters addressed the IR contamination that sensors captured in certain shooting conditions, but with a shift in dark colors. Full Spectrum ND filters are designed to complement refinements in sensor manufacturing that help address IR contamination.

Today, Canon announced the new C700 FF, an update to their flagship C700, which sports a brand new 5.9K (38.1 x 20.1mm) sensor for cinematic, full format imagery. A new Canon CN-E 20mm T1.5 L F Cinema Prime covers the camera's full sensor and fits beautifully with other lenses in the family.

The ZEISS Milvus Super Speed lenses represent all new lens designs in the Milvus family of lenses. The full frame lenses are all f/1.4 (hence the super speed designation), and are available in 25mm, 35mm, 50mm and 85mm focal lengths. They can be purchased individually or as a four lens set with either Canon EF or Nikon F mounts.

ARRI's announcement of the ALEXA LF has the industry buzzing, to say the least, and some people are wondering about the other half of their recent announcement – ARRI's Signature Primes, the large image circle optical companions to ALEXA LF. Looking through the set of announced focal lengths, things get interesting.
