A7R II Firmware Fixes Overheating Issue!? How Canon’s Latest Shutter Mechanism Works, Godox’s New Battery Powered Strobe{Daily Roundup}

By Anthony Thurston on December 20th 2015

Welcome to our roundup series where we will hit on several gear news and rumor topics each day. This gives you a chance to get caught up on all of the day’s news and rumors in one place. Make sure to check back daily for the latest gear news, rumors, and announcements.

Latest a7R II Firmware Fixes Overheating Issues in Video!!!?

In what has got to be one of the most impressive firmware updates, Sony has resolved the much publicized overheating issue on the A7R II.

Generally, overheating was something that I always thought was a hardware issue, so color me very impressed that this was able to be resolved with a software/firmware tweak. I read it on the Sony site, and I didn’t put much stock in it, as I said, I always considered overheating a hardware issue. But then I saw the video below, which – to say the least – is very impressive considering how bad the overheating issue was (for some, I actually never had the overheating problem myself).

The one caveat to the overheating fix is that with the a7R II body, it only works in the Super 35mm video mode. If you want to shoot video in the full frame mode and avoid the overheating issue, you will need to have the battery grip attached. This points to the firmware fix having something to do with power.

Regardless, this is a great fix for those who were considering the a7R II for video. It also removes a major reason why some were choosing the A7S II over the a7R II for video. Obviously, the A7S II looks better in full frame video capture still, and while the a7R II is impressive in low light, it still can’t hold a candle to the A7S II in that regard.

Kudos to Sony for managing to address one of the biggest complaints against their flagship camera with a software/firmware tweak.

Canon’s Latest Shutter Mechanism Is Impressive

A video recently surfaced, courtesy of DP Review, that gives an illustrative – yet really informative look at Canon’s latest shutter mechanism – which is featured in the 7D Mark II.

I don’t know about you, but I am always curious to see how things work and do what they do, and this video is incredibly fascinating to me. It is really impressive to see what goes into a function that many photographers take for granted, and that can occur in just 1/8000th of a second.

Godox Enters the Battery Powered Strobe Game

If there was an overall theme to lighting in 2015, it was the rise of the battery-powered strobes. We had the Profoto B2‘s, Interfit S1‘s, and several others. Well, just in time to hit that end of the year mark, Godox has announced their new AD600 battery powered strobes.

I have not used any of these battery powered strobe systems myself; I don’t do enough on location shooting to warrant the expense. That said, these look to be a pretty solid entrance into the market, with a battery capable of up to 500 full power pops (meaning likely many more than that when shooting at half power or lower).

I think it would definitely be an interesting shootout to compare the Profoto B2‘s, the Interfit S1‘s, and these in a review/comparison. The Profoto lights are obviously very effective, though come at a really steep premium, the Interfit lights are a much more affordable option and appear to perform well above their price class. It will be interesting to see where these Godox units fall on the price spectrum.


That removable head option is also an interesting addition that sort of separates this from your average studio strobe. Stay tuned and I will update once pricing and availability are announced.

    Interesting how you can fix overheating issue with firmware they probably let camera run hot instead of shutting down..

    Mmmm, batter power … :P

    Now I can finally say the A7rll is worth the price tag. That overheating issue was a big letdown. Now I can say this camera is an absolute winner.

    Cheetah or Streaklight will be the same but relabeled. The difference only will be on the warranty every label will offer.

    The Godox AD6000 seems to be a nice product as long as they provide better li-ion batteries than the defective ones they slip into the v850 series.

      I 2nd this. Great capabilities….I’ll either wait for Cheetah or the Streaklight for better quality assurance.

      The Godox product development team deserves kudos for getting nice products to the market at very reasonable prices. But I think customers should be aware of the fact that the Godox equipment isn’t designed for demanding conditions on location. I have four V850 and V860c flashes, as well as a Godox Witstro bare bulb light – in addition to Canon Speedlites and Profoto B1s. The Canon and Profoto parts just work, every time. The Godox: Batteries on the V850 die without warning, meaning I have to bring spares just to make sure the job can be done – not only to switch out when flat. A fall to the ground made the V850 foot disassemble itself in small pieces that flew everywhere (the flash still works, but can no longer be mounted to anything). Another of the V850s can no longer be mounted because the metal plate in the foot is so weak it actually bent when mounted in a Phottix MultiBoom, from the very ordinary force of the fastener clamp coming in from the side. The remotes work well, but are almost weightless – so I don’t expect them to take any kind of beating. The Witstro sure has HSS, but the overheat protection kicks in every time I shoot a quick series of 8-10 frames during a portrait session. Then the flash simply stops working, and I have to wait for it to cool down. I wanted to like these bargain flashes, but it seems that I learned the same old lesson again: A low price doesn’t always mean you’re getting a great deal. Don’t get me wrong: The Godox kits works well for a lot of people, but I wouldn’t trust them for demanding location work. They are cheap for a reason.

      Thanks for that real world review of the V850/60 units. That wasn’t real encouraging.
