The Interfit S1 portable studio flash now has Sony α P-TTL support.

Originally introduced last year, the Interfit, which can be powered from a battery or from the mains, is one of a growing number of TTL studio flashes, which adjust their output automatically to match the ambient conditions as measured by your camera.

There is only one Interfit S1, but now three different remote controllers: one for Canon, one for Nikon and one for Sony. The remote goes on your camera hotshoe, and lets you adjust and trigger your S1 via radio. High-speed sync (HSS) support also means you can synchronise the S1 at any shutter speed, up to the maximum of your camera (potentially 1/8000 second).

The S1 Remote for Sony supports the Sony α6000, α6300, α7, α7II, α7S, α7SII, α7R and α7RII. It has a recommended retail price of $99.99 and will start shipping on 1 October 2016. The Interfit S1 flash itself is listed at $999.99.

As well as Sony support, Interfit is also introducing a new two-light S1 backpack kit. The kit includes a pair of S1 flash heads, two AC power packs, two S1 batteries with chargers, sync cords and micro-USB cables (for firmware updates), as well as a backpack (with movable dividers) to keep it all in.

According to Interfit:

“This backpack is designed to go that extra mile with you. Made from 1000D Ballistic Nylon and Neoprene, the same materials used in hiking packs, means your lights will be well protected. Durable YKK zippers and industrial-grade side release buckles keep everything in place, and should inclement weather catch you off guard, a built-in, rain cover will keep your lights dry. Padded backing, padded shoulder straps with an adjustable sternum strap, and a padded hip belt create a comfortable carrying harness, making your next photo excursion a breeze.”

The backpack kit retails for $1,999.99 and is available now through authorised dealers, such as Adorama, and the Interfit web site.
