This is an incredibly geeky topic, but it’s a subject I find absolutely fascinating. It involves how flashes communicate with the camera and reverse engineering the “language” they use to talk with each other. In this video, Roger Nieh of Science’n’me takes a look at the Canon flash protocol using an oscilloscope to eavesdrop on that communication.
Good news for Sony shooting team will make portrait photographers especially happy: Sony has announced two new prime lenses for their full frame mirrorless cameras. One is Sony FE 100mm f/2.8 STF GM OSS, and the other is Sony FE 85mm f/1.8. In addition, they have also announced a new wireless radio flash, Sony HVL-F45RM.
Sony first mentioned their new wireless radio controlled flash system in March and officially launched it in July. It allows the control of up to 15 separate flash units in up to 5 different groups. A very useful and welcome addition for Sony shooters. But, not every camera has been able to support the new system.
Sony have now released firmware v3.30 for the Sony A7R II. This update adds support for the new system, as well as a couple of other fixes and features.
