Isotta RED64 i-TTL Underwater Strobe


Coming Soon. Isotta RED64 i-TTL Underwater Strobe.
Now Taking Pre-Orders. Pricing subject to change.

Over 30 years after its first breakthrough flash, the Isomat 33, Isotta has returned to its roots with this brand new and powerful underwater strobe. Isotta is proud to announce the Isotta RED64 with guide number 64 in its signature red anodised aluminium finish and double O-rings.

Isotta’s RED64 was designed and produced in Italy as a result of 4 years of research and development in reverse engineering. It's TTL protocol has been tested on all Nikon DSLR cameras and an extensive test series on functionality and endurance and will soon be completed for all other relevant camera brands.

Product Details

Isotta's RED64 strobe features a thorough design, shielded electronics isolated from the control panel and a microprocessor with a software that can be upgraded guaranteeing a high-quality performance in time. It is also neutrally buoyant in water and waterproof up to 100 metres. The strobe emits a wide and homogenous spread of light with no hot spot thanks to a xenon toroidal lamp and a warm colour temperature of 5300 K essential for capturing bright colours underwater.

Being one of the most powerful strobes in the market it gives photographers the maximum light in every situation, illuminating details even in the darkest waters or against the light.

Isotta's RED64 features a guide number n.22 in water (at 1 metre of distance, 100 ISO) allowing for a great power underwater and ideal to shoot against the sunlight and with big or distant subjects. Its beam angle of 130° degrees is achieved with its parabolic aluminium dish, spreading light without a diffusor and avoiding backscatter. The strobe has a two colour target light (white and red) from which to choose depending on the photographer's needs.

Different to all other high-power strobes in the market the batteries section allows photographers to use their own 8 Ni-MH-AA rechargeable high-quality batteries, in a compartment sealed and separated from electronics. This not only allows for flexibility at the location but also a big cost saving.

The RED64 Strobe is ergonomically designed with controls visible from every angle. A multi-colour LED indicating activity and strobe readiness as well as battery status. The strobe can be controlled both automatically and manually: RED64 can be operated with an optical fibre cable working in TTL mode and as well in Manual. Alternatively, it can be used with sync cables through a S6 bulkhead or Nikonos V or in even in slave mode to work without cables.
