The product is under development. OPTIMA underwater strobe has the following features: – Best TTL accuracy. TTL control system inside the strobe is created by the leading manufacturer of TTL systems on the market, – Underwater Technics company. All original TTL Converters contain TTL-profile specially developed for OPTIMA strobe support. – Best HSS quality on the market. It allows shooting at shutter speeds up to 1/8000s without banding (!) on the image, – provided by the new methods of HSS control. Patent pending. – Circular shape flash tube provides a very uniform lighting on the whole area of the shot, especially in combination with the spherical dome. – Spherical dome is made of ultra-high temperature optical plastic. It has an anti-reflective coating of inner surface, just like the best optical dome ports. – Extremely fast strobe recycling – 0.8 sec (after full flash dump). – Flash light beam angle underwater – 140 degrees. – Flash modes switching by the strobe knob: “TTL”, “HSS”, “M’. – Intellectual flash control by camera menu via UWTechnics TTL-Converter, including “Flash Exposure Compensation ( /-)”, “Front/Rear curtain sync”, “Slow sync”, “TTL”, “HSS sync”, “M” (also available M flash power adjustment via camera scale / controls). – Continuous (“serial”) shooting (under UWTechnics TTL-Converter control). – “Multi-Flash” shooting at slow-speed synchronization (under UWTechnics TTL-Converter control.) – Body and all parts are made of hard-anodized aluminum alloy, – Flash power 160 Ws, Color Temperature 5500K, – Pilot / focusing light 600 lumen with Auto-Off function during the flash. It also can be used as a comfortable torch for the night dive. – Professional Video-light 16000 lumen, true colors CRI 92, Color Temperature 5000K. – Video-light working time (at 16000 lumen): 44 minutes with large battery (8 cell), 18 minutes with small battery (4-cell). – Logarithmic scale of video-light flux adjustment, which has advantages for professional video and human eye perception. – Video-light adjustment range: 0….16000 lumen (8 steps). – Video-light beam angle underwater – 140 degrees. – Battery construction: 4 x 18650 cells (small battery), 8 x 18650 cells (large battery), including cell Balancing and Protection electronics. – Battery compartment screw cover sealing has a dual o-ring. – Battery compartment is internally sealed from the electronics of the strobe. – Battery level indicator on the strobe body. – Protection Valve on the strobe body, – for safe Li-ion battery usage. – Original traveling case has recesses for 2 spare batteries. – Strobe weight (including standard battery) in air – 1.2 kg – Strobe weight (including standard battery) in fresh water – 0.2 kg. – Bayonet front mount, – for snoot, color filters, reflectors and other external accessories. – Optional External Reflector (with bayonet mount) provides more narrow beam angle,- for different shooting tasks. – Optical Snoot, External Reflector and Color Filters exist in the production plan in 2026. – Certification CE and FCC.
