7D Mark II missing a simple feature from the 70D and Rebels

Lee_Jay — Sun, 19 Oct 2014 23:54:05 GMT

Please add, by firmware update, the 3x digital zoom (1:1 pixels, really 2.875x) in video feature present in the 70D and many of the Rebel cameras. I can attest to its usefulness from my use of it in my T2i. It's useful for astrophotography, specifically planetary astrophotography where large stacks of video frames are used to create a much better still than can be made any other way. It can also greatly extend the usefulness of a lens like the 18-135STM which would reach 135*1.6*2.875=621mm equivalent without the need to upscale. Finally, it would add the ability to take videos of, say, birds that are of the same resolution (resolving power, not pixel dimensions) as can be obtained from stills.

Ideally, it would be possible to smoothly zoom from full-frame to 1:1 and back using buttons on the back of the camera while shooting is in progress, but even the awkward menu item as it is implemented in the other cameras would be preferable to not having the feature at all.

Further, if it could be implemented while retaining dual pixel focusing (which the 70D does not) that would extend its usefulness even further to moving objects from stationary objects only.

The 7D2 looks to be a spectacular camera with a powerful feature set, which makes it all the more odd that this feature was left out.

Thank you.

Digital zoom is not really zoom, it is in camera crop then enlarge which can be done in post process. It is considered gimmick for consumer market so you will not likely to find it in pro-targeted camera. Same thing with why you do not find those automatic shooting modes on pro camera. Thus, i think you will never see it implemented.

As I said, I'm talking about video, where it cannot be done in post processing.

"As I said, I'm talking about video, where it cannot be done in post processing."

No matter, hsbn is correct. It is a gimmick and not likely to be included in a semi-pro body.

He is NOT correct, and you both don't know what you're talking about.

This is not upscaling, and not at all the same as digital zoom on stills (which is nothing but cropping and upscaling). This is capturing the center of the sensor at 1:1 - 1 output pixel for each sensor pixel.

This sensor is 5,472 pixels wide, but video only puts out 1,920 pixels wide. Thus normal video mode resamples (and, possibly line-skips, but it looks more like pixel binning on the 7D Mark II) the entire high-resolution frame down to the low resolution of video output.

The mode I'm asking for captures just the center 1,920 horizontal pixels of the frame and outputs those as the video - no upscaling. It can be cleaner than full-frame because there's no rescaling going on, and thus little or no aliasing artifacts (moire).

This is a highly useful mode, and it is available on $10,000+ astrophotography cameras. It is not a gimmick as there is no other way to do what this mode can do - capture video at the full resolution of the sensor.

Well it won't be the first time! But we'll see if Canon does so.

Watch this video, shot with a 70D. He's shooting with a 400mm lens. At 0:36, he changes from full-frame (regular) to 3x mode.

Now, I agree that the 3x-10x range (which he starts doing around the 1:15 mark) is a gimmick as it's just useless digital zooming and enlarging, but switching from full-frame to 3x is most definitely not a gimmick. And, if you look back, I'm looking for 1x-3x (really 2.875x) not the useless digital zooming from 3x-10x.

I only can say frome experience, but Canon normally doesn't do these kind of thing. I think you'd have better luck trying Magic Latern. Hopefully, someone over ML needs the same feature as you don and enable it (or may it already does).

"But we'll see if Canon does so."

Still betting Canon doesn't add it to a 7D Mk II, or any other semi-pro or pro body.

ML has it (and since that application is targeted at pro video...you see where I'm going), but not of course for the 7D Mark II yet. Since the 70D isn't even supported by ML yet (difficulties with the dual-DIGIC, I surmise), it could be a while, if ever.

It's such a useful feature, and the 7D Mark II has so many dedicated video features (dual CODECs, All-I, dual-pixel, movie servo AF, etc.), I can't see why they left it out, especially since it was already in the 70D. It could be the same issue - DIGIC 6 versus DIGIC 5. Maybe they didn't want to tackle some software change that would have been needed.

My Rebel T2i at work has this feature, and I've used it at work for professional engineering purposes on several occasions.

For giggles, I also shot this with it at home:

Even if Canon decides to implement it, it will take years before they roll out the new firmware unless there is overwhelming demand. 🙂 So I would place my bet on ML that they'll support it first before Canon.

The T3i had this feature too, which is why it is so popular with videographers. It was removed for the T4i, and although I know they discussed bringing it back with the T5i I don't think they did. Though I could be wrong.

Canon should include this feature in every camera they make that has video.

The 3x "digital zoom"/1:1 crop from the 70D was exceptionally clean, since it was simply choosing the central pixels. I used this a few times and it was very handy. I have since upgraded to a 7D MKII and was looking for the function today. I'm not surprised it's not here (canon has a history of hiding useful capabilities that the hardware has) but it would be much appreciated if they brought back this feature.

Since this thread was brought back to the top, let me mention two more 7D Mark II nits I'm having.

One, in video mode with servo focusing on, only one of the modes supports the option to change speed and responsiveness - FlexiZone Single. I really, really need this option in FlexiZone Multi. I shoot a lot of airplanes in flight, and if I don't keep the plane perfectly centered, the camera tends to try to focus on the blue sky pretty quickly, which of course it can't do. In FlexiZone Single I turned responsiveness down to -2 and I only need to get the plane into the tiny center box once ever second or two to keep it tracking, but even doing that is quite difficult at long focal lengths with quick airplanes. If I could do the same thing with the much wider area of FlexiZone Multi, it would work way better, but in that mode responsiveness is stuck way too high. As soon as Multi loses the object for an instant the camera tries to focus on the sky.

The second one, is the customizable buttons, specifically the M-Fn button. None of the things the camera allows are things I actually want to do with it. What I want it to do is to turn on and off the grid and/or the electronic level. There should be options to turn on one, the other, or both, and of course off should be the other option. The final option should be to cycle through off, grid, level, both, and back to off.
