We've recently received a number of calls asking about the functionality of the OptiTek Mark II on Sony cameras (F3/F5/F55). In today's Quick Tip, I will take you through the steps to get the adapter up and running.

NAB is always full of exciting gear announcements and reveals, and this year was no different. Our specialists posted lots of great coverage from the show floor, which you can check out in our dedicated NAB 2014 category. Even if you didn't get a chance to attend, you can still get a feel for some of the show's highlights by checking out the videos below.

At their NAB booth this year, Zeiss showed off an interesting new option for their Compact Zoom line of lenses.

Alongside the AMIRA in our booth, we displayed another new accessory from Arri, the EMC-1 ENG Motor Controller. Designed to be used with ENG-type lenses such as the Fujinon Cabrios, this unit controls the focus, iris, and zoom motors, along with providing lens data that will be displayed on the WCU-4.

Fujinon announced the 25-300 as the newest member of the Cabrio family right before this year's NAB show. The lens is designed for 4K Super 35 sensors and, with a 12x zoom ratio and constant aperture of T3.5 from 25-273mm, is definitely meant to compliment the rest of the Cabrio family.

I stopped by the Zacuto booth to talk to Steve Weiss about their new Gratical HD. The Gratical HD is an OLED EVF with 1280x1024 resolution and a high-quality diopter. Other key features include HDMI and HD-SDI in/out (HDMI cross-conversion to SDI), waveform, vectorscope, histogram, and LUTs.

We've previously blogged about some of OptiTek's optical adapters, and this year at NAB they're showing off an updated version of their OptiTron - the OptiTron 2.

Complimenting Sony's new ENG/EFP Build-Up Kit for the F5/F55 is their new B4 2/3" to PL optical adapter.

Today Fujinon introduced the newest member of their popular Cabrio family of lenses; the all-purpose Premier PL 25-300mm (ZK12x25).While not as lightweight as the other Cabrios, the versatile 12x zoom ratio and constant aperture of T3.5 from 25-273mm (gradual ramp to T3.85 from 274-300mm) will surely feel at home on any set and compliments the existing lenses.
