EOS 7D Firmware v2 tested with radio Speedlites

It’s taken a couple of days to get back from my trip to Finland for the rally and get the EOS 7D updated to the version 2 firmware that just came out. While I really appreciate the changes and the new lease of life the update gives to the EOS 7D I wanted it so much to work completely with the Speedlite 600EX-RT and ST-E3-RT.

You may recall I did a check with the EOS 7D running firmware v1.2.5 to see how the pre-2012 camera worked with the latest Speedlite flashes, and the result was better than I had expected but not all I wanted.

Speedliters, it’s no better with radio flash 🙁

So now with the great free performance update that v2 firmware brings to the EOS 7D I had high hopes that there would be even more than what Canon had committed to. The reality is that there’s no advance in how the EOS 7D with firmware v2 handles the extra functions that the Speedlite 600EX-RT and ST-E3-RT introduce to the 2012 model cameras.

I’m now wondering if the reason is that the exposure system is not firmware updatable, maybe the radio flash and five groups requires a DIGIC 5 processor, since the full features of the radio flash work with the EOS 650D as I proved last week.

Back in reality, I really think the firmware update is a great thing, most of the EOS 7D owners will get better performance, some great enhancements, manual audio recording levels and plenty more. So if you are sitting on the fence about upgrading your EOS 7D, then my advice is just go ahead and do it and then enjoy using your existing kit even more.
