1 pointWith my A6300 and UWT trigger, setting it to speeds higher than 1/160 puts the trigger in HSS mode. By the way, I just tested my setup - A6300 with 90mm f/2.8 G, UWT trigger, Retra Pro with supercharger, manual mode, 1/160s, f/2.8, ISO 100, camera set to WL flash, Retra set to manual mode ('ON') and 3% power (2 clicks up from minimum) and it had no problems producing full exposures in both Hi and Hi+ drive modes.
1 pointI was watching the backscatter promotional video where Robin says the M52 wide angle air lens reduces macro distance but not much. I wanted to quantify not-much. Here are two photos of an RFID chip that measures 7 mm. I made the test simple. I literally laid the camera down on the chip and focused. First without the wide angle air lens and then with. Photographs are worth a thousand words.
