The built-in flash pops up from the camera body & is folded back down when not in use, but I never thought to manually bounce it! I tried it out today, and it works beautifully. Keep in mind that this isn't a replacement for a true external flash, but in a pinch, it works very well. You kind of have to experiment with it since there's no way measure angles etc, but I could accurately guesstimate results after playing around with it for a bit. What worked well for me was to use my left hand pointer finger on one corner to (gently!) pull it back at whatever angle, and press the shutter button as normal with my right hand. If I needed to do any fine-tuning via manual focus, I did that first. I'm stoked about this nifty little feature - it will definitely come in handy when I don't want to lug around a flash bigger than my camera! Comparison photos & brief how-to video below!
I thought I’d mention that you can technically bounce the light from the built-in flash if you ever find yourself without an external flash to hand. You can only bounce it in one direction though – up from the camera! Just tilt and hold the flash back manually.Vannio
For reference, bounced photos are on the right, normal flash photos are on the left. All photos are unedited, straight from the camera.
