Aquatica just announced an exciting new development and partnership between them and Ikelite. Starting with the upcoming housing for Canon 7D Mark II camera, the two companies will be partnering to bring the world renowned Ikelite TTL control circuitry in the Aquatica housings. This new development means that you can have the high quality aluminum housing, known for its rugged construction and nice ergonmic design complete with full TTL control when using Ikelite strobes and sync cords.

Using sync cords allows you to take advantage of the lightning fast recycle rate on the strobes, and Ikelites TTL circuitry keeps up with that fast recycle rate, providing accurate flash metering to give you a well exposed image automatically.

TTL is great when you are shooting in situations where taking the time to adjust the strobe power and dial in the shot may mean you miss a fast moving or shy subject, so the pairing of the excellent Aquatica housings and Ikelite TTL looks to be a very promising solution.

The first housing to have this built in will be the Aquatica housing for Canon 7D Mark II which should be shipping at the beginning of 2015.

Last year, 2013, at DEMA Sea & Sea announced their upcoming innovative Optical TTL YS Converter. Several other manufacturers had also been releasing information on other strobe triggers, but what set Sea & Sea apart was that theirs actually worked with TTL on Sea & Sea strobes. Other strobe triggers or converters so far only allow you to get faster recycle speeds by bypassing the onboard camera flash, however you have to control the strobe manually. Being able to shoot in TTL gives you even more chance of nailing the shot for those fast moving subjects when there is not time to make strobe power adjustments.

The Optical TTL Converter has been available for a few select housings, such as the Sea & Sea Canon SL1 housing , Sea & Sea Canon 70D housing and Sea & Sea D7100 housing. Coming soon Sea & Sea will have a version available for the new Sea & Sea Canon 7D Mark II housing, Nikon D810 and an updated housing with fiber optic ports for the 5D Mark III which will also be compatible. This year at DEMA we got a first hand look at how fast the Sea & Sea strobes can really recycle, when shooting TTL, through the use of the Optical Converter.

The housings in the video are set up so that the one on the left is shooting TTL by using the camera’s onboard flash which adds drain to the camera’s battery since the flash is powered by the camera. The housing on the right is set up to shoot TTL through the optical TTL converter which is powered on its own, and does not add any drain to the camera’s battery. In addition, since the camera is not using the onboard flash, the strobe does not need to wait for that to recycle before receiving more information and the camera is free to shoot at its max speed, since the Sea & Sea strobe can recycle lightning fast. Take a look.
