New toy! When I was a neurosurgeon, we (our specialty) got the best toys. (He who dies with the most toys wins.) Bluetooth. I’m hooked into the new camera with my phone and with a dedicated remote. This is the first camera I have that is capable of firing via Bluetooth. (It’s not my first ever remote.) It’s new technology which opens up a whole new avenue of possibility. It’s not brain surgery. But the toys are getting better and better.
