Patent: Optical formulas for Canon RF macro lenses

Can I hope and hope that there might just be an updated RF 65mm lens like the MPE-65. From my handheld macro perspective IS isn't much of an issue or want, since at +1x or more I feel that it wouldn't have much effect. Anyone on here use the MPE-65 on a EOSr body?
replying to myself for others. Using the mpe-65 on the r5 and absolutely love it.

R5 detailed lens testing of RF 100-500 f4.5-7.1 vs. RF 800 f11, with & without RF 1.4x TC, for super-telephoto use.

Just went out and tried the bare 100-500mm on the R5 and Saturn. Hand held at 1/250 and iso 3200. My first ever shot of Saturn.

View attachment 200358
I have early access to an R3, so I mounted my bare RF 100-500 on it and took my own picture of Saturn.

That's what happens when you're stuck with a measly 24 MP.

Tether - lose connection, why?

Does your older notebook have a USB 2, 3, or 4) port? The older notebook may be USB 2 which accepts longer cables but slower speeds. The newer one might be USB 3.1 which is more sensitive to long cables but not as critical as the USB 3.2 or USB 4 version. Its very confusing. Those names like Superspeed confuse the issue. USB 3.2 and higher always use a USB C connector but now, USB 2.0, 3.0 and 3.1 can also have a USB C connector.

Canon R5 AF points

Typically (unless I shoot something that moves too fast, like BiF, or need precise manual focusing) I use tracking autofocus starting from preselected focus point. I move the focus point with joystick - or press the joystick to select the central AF point, then focus and recompose. As the AF is still tracking the selected object while I recompose, there is no problem with focal plane shift even at 14mm.

R3 rolling shutter, is it much of an improvement over R5?

I am a hobbyist but understand there are those trying for or having to adhere to the highest standards. I also take any test trying to find a problem with a grain of salt. A quick panning motion, very long straight vertical line that over the entire frame is a torture test that may or may not affect your actual photography.

I am currently shooting the R5. I usually use some variation of a mechanical shutter, but here are two images shot the the electronic shutter only

So, even with the R5, electronic shutter is working for me. The R3 is even better. Until there is a global shutter, faster readouts only mean there are fewer instances where rolling shutter will be an issue. You'll have to judge when a camera has crossed the line for you.

Yes I have had usable images in electronic mode also, but I can't trust it enough to capture the decisive moment without something looking unnatural (background or subject matter). When shooting sports you can't always predict when you might need to pan and follow an athlete - hence why I shoot all sports with the mechanical shutter.

If I were shooting just for myself it would be a different story.

Preorder the Canon EOS R3, RF 16mm f/2.8 STM, RF 100-400mm f/5.6-8 IS USM and accessories

I call BS on Canon's "the order have exceeded our expectations" nonsense. That was believable for the R5/R6 but this, it's marketing nonsense to get people to think the R3 is in crazy hot demand. Given everything else that's been blamed on the pandemic, to say the short supply is due to unexpected demand is laughable. And just to be clear in case it's not evident, this is just my opinion that I cannot back up with any hard data or facts. ;-)
I would say you are half right. If demand for the R3 exceeded expectations, then Canon needs to take a serious look at whatever division is in charge of sales projections. If a multinational corporation like Canon can't accurately predict demand for new products, they are doing something wrong.

I would say you are wrong that "it's marketing nonsense to get people to think the R3 is in crazy hot demand."

Demand is likely to exceed supply because of pandemic related supply chain issues, but without Canon releasing more sales figures, we won't know what the demand actually is, but I suspect that the R3 is going to be in "crazy hot demand."

A Canon Speedlite EL-10 is coming in 2021 [CR2]

Here's my thoughts on the EL-1 flash head. Yes it is very, very good. But 170 flashes in a row as the limit? It's not entirely beyond the realm of possibility to hit that, not at all. I find that limit to be semi-professional at best. So I have to agree with you on this flash, it is overpriced for what is on offer
I actually took the plunge and bought one. Maybe in the future I'll be kicking myself for not waiting for price to go down, but I have to say the flash has so far impressed me in an event- shooting capacity. I can say without any exaggeration that it easily out performs the 430s and 600s as far as how long I can shoot, and how rapidly. It easily keeps up with 12 fps over and over again. I've had 430s and 600s stop flashing from rapid fire shooting numerous times, but this EL-1 just doesn't stop! Plus, only one battery charge for the entire evening and I was still showing 4 bars on the battery meter.

Here is the official marketing material for the Canon RF 16mm f/2.8 STM, Canon RF 100-400mm f/5.6-8 IS USM and accessories

Have you seen the bottom of the ST-E10? Look Ma, no pins!

While the new R3 hotshoe replicates the pin contacts of the old one, for the new flashes (if the ST-E10 is representative) all of the communication appears to be via the new ‘Lightning connector’-type contacts.

Also, those new contacts protrude toward the front of the camera, and I think that means they’d come up against the front of the old-style hotshoe and not allow a new flash to slide far enough forward to engage the locking pin (even if new flashes differ from the ST-E10 and have actual pin contacts).

So, I think there are both electronic and physical reasons that new flashes won’t work in old (pre-R3) cameras.
Thanks, I hadn't seen the illustrations.

I hope those lightning-type contacts aren't as fragile as they look. My wife just managed to snap off the lightning connector when unplugging it from my Mac keyboard...

BEWARE: RF 14-35 f/4L IS USM

No, there's never been any kind of schedule. New bodies usually get support within the first two weeks of on-shelf release, but lenses can be anything from a few days before units hit shops, up to a month or even two afterward. It just depends on how fast Canon move, what else they've got on their plate that they prioritise more. Given how slow all development, production, distribution and other fundamental work is going right now (and will continue to be slow until covid is a distant memory), I wouldn't like to try to estimate when a profile will show up. It'll arrive when it arrives.

Here’s a full list of what will be announced with the Canon EOS R3 this month

  • ST- is a Speedlite Transmitter, I suspect they jumped from the ST-E3-RT to the ST-10 with new features using the extra hotshoe connectivity
  • AD- is used on some of their power supplies, so I suspect it's a power adapter of some sort but that's a guess. Maybe a USB-C PD adapter to power the camera and charge a battery in-camera?
  • DM- is directional microphone (I have the DM-100 for my Vixia camcorder, there is currently a DM-E1 for for EOS cameras, so the DM-E1D should be similar
  • ER- denotes a strap, e.g. the ER-100B is the neck strap for the EOS R
One interesting thing to note...
The ST-E3-RT sells for $300+, and this new ST-10 has leaked pricing of $119.
Almost as if it's a more entry level transmitter, but for a fancier hotshoe? I'm curious to see how this gets pulled off?
