What's new in this version. FLASH You can now work out the exposure for a shot with flash. Enter the flash's guide number, the power you set it to (1/1, 1/2, 1/4…) and the distance to the subject: Lume adds the flash to the ambient light and gives you the correct aperture. Power matters — the same flash at 1/8 is three stops weaker than at full. AUTOMATIC DISTANCE On models with LiDAR the subject distance is measured exactly where you aim the reticle, in real metres. No more guessing. FLASH AND AMBIENT BALANCE Shutter speed meters only the ambient light — the flash doesn't feel it. Turn the shutter wheel and watch the share of the exposure coming from the flash change. There's a warning when you go past sync speed. WHEELS The wheels now track your finger precisely: the strip moves exactly as far as your hand does, so it's easier to stop on the value you want. The reticle now shows the calculated value — shutter, or aperture — instead of the EV.
