Quick Review of the Canon G7X Mark iii as a Video Camera

I received the camera, read the manual (which all the "influencers" with their videos at product introduction did not have (as it only became available today worldwide), and shot some video.
Here is what I learned, the good:

1. Audio: Manual audio, with fine settings, plus options for a limiter and/or wind reduction. Audio meters; mic-in jack but yes, no headphone jack but meters do not lie.

2. 4K video: You can shoot 4K video with all manual settings, or with ISO auto, adjusting separately shutter and aperture and ev.

3. You can view a histogram in real time, but no zebras.

4. In auto ISO you can half press the shutter to get a readout of what the ISO actually is in real time. No other camera allows this (well, not any Panasonic or Sony camera, even mirrorless).

Output: In 'Standard' picture style the colors are nice, highlights are a little hot, but easy to tame in post.

5. The 4K bitrate is actually 123 Mbps, not the 100 Mbps in the specs - that is good.

6. Focus: You have the choice of servo (active) focus and there is an icon on the screen to turn it on and off. This is what I do - I select with my finger what I want to be in focus on the lcd, that puts the focus in tracking mode, so that if the subject moves focus follows. If the subject is static, sometimes a change in light causes the focus to shift, so for static subjects I turn off servo and the focus is then locked in place. So, focus is fine. You will see in the video how it does, with most shots using the servo (tracking) focus because the flowers were moving around in the wind.

7. There are three stabilizing modes: optical only, and two digital supplements ,which crop. My video only uses optical stabilization to maximize resolution. There is also a special stabilization for panning (why? so the stabilizer does not resist purposive movement up and down or left and right for pans)!

8. Built-in 3-stop ND filter - what a convenience!

Ok, here is a 30p 4K video I shot today in 'Standard' Picture style, with sharpness turned down one notch.


Oh, yes, the bad: Camera (and I) overheated after 45 minutes of shooting short clips. Worst-case scenario: 90 F in direct hot sun.

7. You can shoot 30p RAW video in 5.7K. Yes, real RAW video. For over 2 seconds at a time in RAW burst mode.

This 4K video was shot RAW 30p:

Mark, what prompted you to buy the Canon? What was it offering that you felt was missing with your current gear?

This does not have an EVF, correct?

No EVF, so not for you!

At the time, five new features: ND filter built-in (that really makes a difference), mic input, full touch screen, fast lens with extended range, superior stabilization even if just optical, all relative to the RX100 VA (comparing pocketable cameras).

So, (ignoring EVF), superior to RX100 VA in features in many ways. Now, with respect to the new RX100 VII: the Canon has a faster lens, likely better IS, full touch screen, ND filter built in. Plus 30p RAW video for over 2 seconds. Of course, I am ignoring the Canon's ability to live stream, since I won't do that!

So, the only questions were, how good is the Canon 4K and how bad was the AF? And luckily both are fine (yes, the PDAF of the Sony is better, but it really is not that much better for what I shoot). AF test video coming up.

But, back to dealing with over-heating.

Oh, and the Canon is much cheaper than the new Sony RX100 cameras.

I think the latest RX100 does do active IS in 4K, unlike earlier versions of the camera.

Yes it does, so both Sony and Canon have added digital IS options. I only use optical to preserve resolution and avoid crop. And the non digital IS is better on the Canon in my experience.

At the Worst Yankees Game of the Year

Check the scoreboard shots. But everyone has a great time anyway. And the camera does a great job looking on (there's even one baseball play):

There has been no 24p lately in many new Canon cameras. They apparently have upped their product segmentation game.

New frmware for better AF!

https://www.usa.canon.com/internet/p...loads-firmware

Firmware Version 1.1.0 incorporates the following enhancement:

A new mode for Movie Servo AF has been added. Autofocus characteristics for Movie Servo AF can be set to [Mode 1], [Mode 2] or [Disable].
- Mode 1 (newly added, with firmware version 1.1.0): This mode supports quick and responsive autofocus. Use this autofocus mode when you want the camera to be sensitive to tracking the subject, and for situations when the photographer is moving (such as shooting while walking).
・Mode 2 ((current, with firmware version 1.0.1): This mode supports smooth and natural autofocus when shooting movies. Use this mode when shooting landscapes or subjects with little or no movement.

"If you prefer the previous AF characteristics, please select Mode 2 after the firmware update."

And Canon has announced another firmware update to come before the end of the year that will add 24p video! Why anyone cares is still a mystery to me, but evidently Canon actually listens to gripes (AF and 24p).

Yes, who would have thought reverse-crippling the frame rate down from 30fps to 24fps could make things all rosy again.
