Canon EOS R7 Mark II is Reportedly in the Wild

[Canon Rumors]

The Canon EOS R7 Mark II is coming in the next 4-6 months, whether that’s an announcement date or a shipping date isn’t known at this time. We were recently sent an image of what does look to be the follow-up to the EOS R7, but we were not given permission to post the image […]

Please, reduce/eliminate the rolling electronic shutter, please!

When the D7 Mark II came out, it was great primarily because it could shoot so many frames per second (10!) For some users it was better than a 5DIII mostly for this reason. Now that FPS is now a solved, making an action crop camera may take some borrowing from other 3/1-series features. Because of the mention of the big top lump, perhaps pupil autofocus control? That was a nice add to the R5 II.

And minimize shutter slap in mechanical
And of course fix the AF accuracy issues
Then my preorder will be certain

I going to assume that Canon heard everyone and resolved those issues but only so I can give them my money when it's released. I wanted a APS-C and because of all the noise around the focus and rolling shutter issues picked up a R50, decent little camera but......

The R50 has a sensor readout time of 35.3ms, which means more rolling shutter than the R7 with 29.2ms time. I don't find AF problems with the R7. it's by far the best Canon APS-C.

Well for $539 vs $1500 for the R7, I was just looking for something to get by while I waited for the release of an improved APS-C in the Canon line. I got my money's worth but I'm glad you like your R7.

Thread 'Shutter shock on the R7'

Aug 1, 2022

There is discussion in various forums about shutter shock with Electronic First Curtain Shutter (EFCS) with the R7. I have been following this and have done careful tests of my own with charts and would like to sum up the situation. Shutter shock can occur when any shutter is opened mechanically and it causes a vibration, independent of whether the camera is mirrorless or a conventional DSLR, unlike mirror slap that can't occur for mirrorless. EFCS is designed to avoid this as the shutter opens electronically and closes mechanically, after exposure. But, it has been noted with the R7 in...

The "noise" that put you off the R7 about the rolling shutter and shutter slap on the R7 comes as usual from those who don't know how to use a particular camera (or lens). It's the constant problem on the net - complaints from those who haven't tried or haven't the ability to work around problems or who are just chronic naysayers. Use ES in situations of speeds where shutter shock would cause problems and rolling shutter is not problematic. That actually covers by far the most of its use. Rolling shutter can become problematic where there is fast movement. But, that is the situation where you usually need fast shutter speeds and that is where there aren't any problems from shutter shock if you use mechanical shutter, or you can use EFCS. My wife uses the R7 for birding and it's always in ES mode for what she does with no problems for static birds and she switches to another shutter mode for BIF. When I borrow it for insects with rapidly moving wings, I use ms or EFCS. I presume you do the same with your R50.

Thanks Alan, I got this...

Panning shots of race cars and motorcycles are a real problem. I pan with the car or bike with a 1/60 or 1/125 shutter speed to maximize background blur except the blur is tilted.

Nearly all cameras suffer rolling shutter under those conditions. The Sony A9iii with its global shutter is the best for you.

Getting back CR's short update about R7II rumors. Here are my personal preferences:

• Camera body is bigger than the EOS R7
  • Great! The original R7 is really a bit too crammed.
• The EVF bump is bigger
  • okay
• The joystick has been moved to a more conventional position on the back
  • Now THAT would be GREAT! I think a lot of Canon users welcome such a leap back to the standard layout.
• The rear LCD appears to be able to tip up and down, though we don’t see it flipped to the side as we’re used to in the Canon world.
  • hope it will be as flexibel as the original R7's LCD, it is in particular useful for macro shooting
• There is no top down LCD.
  • I still use it on my 5D4 but did not really miss it in my original R7, since I can check all important settings in the EVF - so that would be no real drawback.

Or just use a mechanical shutter. Some of my best panning pictures were taken on film using an EOS-3. At 1/60 second, the keeper rate is pitiful.

A mechanical shutter has rolling shutter at about the readout time of an R1 or R5ii. This is because the shutter is an open strip travelling vertically so the shutter is open at the top 2-5ms or so differently from the bottom. As I mentioned earlier, I use mechanical at high shutter speeds on the R7 to minimise rolling shutter. The Sony R9iii is the only commercial body that entirely eliminates it.

Is the slit vertical traveling horizontally or horizontal traveling vertically? Your reply assumes the latter. I believe the EOS-3 and other film cameras moved horizontally. The effect should be to lengthen the car or motorcycle in the picture.

Since the DSLR days Canon's mechanical shutter moves up&down(horizontal travel vertically). I'm not expert in older SLR, and my 1V's mechanical shutter is no different to modern cameras. I don't know Canon did something different for 3.

 

[AlanF]

As @DhlcadR6 writes, modern DSLRs travel vertically because it is quicker to traverse 24mm than 36mm.

All EOS SLRs, both film and digital, have had electronically controlled vertically traveling blade shutters.

The AE-1, AE-1P, New F1, and most other late FD mount bodies in the A-Series and F-Series had horizontally travelling one-piece cloth shutter curtains. This made camera design simpler so that the same mechanical motion from the film advance lever also cocked the shutter curtains. The final FD mount bodies, the T-Series introduced in 1983, had vertical shutters. There were also a limited number, reportedly less than 100, of New F-1 bodies made for use by press photographers at the 1984 Summer Olympics with vertical blade shutters, enhanced motor drives, and pellicle mirrors that could shoot at a then record 14 fps.

The tipping point for going from horizontal to vertical shutter curtains was the elimination of manual film advance levers as 35mm film cameras were introduced with automated film advance built into the body. The shorter transit distance across the short dimension of the frame and blade curtains driven by electronic motors rather than cloth curtains resulted in shorter X-sync timings. Instead of 1/60-1/90 X-sync Tv, cameras quickly went to 1/120-1/180 X-sync for flash photography. The T-90 had an X-sync of 1/250! The professional New F-1 with horizontal cloth shutter was limited to 1/90 X-sync.

For what it's worth, my Konica FS-1 has a built-in 2.5 fps motor drive and a vertically travelling electronically controlled blade shutter. It was introduced in 1979, about four years before the 1.5 fps Canon T-50.
