My newest DSLR is a Canon 77D that I got for my birthday. Among its many awesome features it has built in WiFi with NFC to allow connection to a mobile device.
The other day, I tried a new technique where I used the Canon EOS Utility to make a wireless tether connection between a laptop and the camera. With the EOS Utility, I was able to set the camera on a tripod at ground level and take a series of shots at different focal lengths. Here's the result of my first attempt:
This was created from a 9-shot focus stack.
I used to be able to do this sort of thing using MagicLantern on my EOS T2i, but there's no current support for it on the 77D. With the EOS Utility, I can control the focus from my laptop in increments. While not automatic like MagicLantern, I do get to see what the camera is seeing on the screen of my laptop. The software even allows for 5X zoom to make fine focus even easier.
I had been able to do some of this previously using the Canon Camera Connect app on my iPhone or iPad but the focus control wasn't as easy for me. Maybe I'll play around with that some more and report on the results later.
