Maybe Canon wants to skip minor changes and is thinking about a real leap forward IMO this might be a global shutter or at least a really fast readout of the sensor for video and electronic shutter as a real difference between other offerings.
To make such a sensor in a e.g. 2000 €-body is a large step.
Looks like Canon just opened the door for the Nikon Z90.
I know, I loved to follow his blog for many years. But in real life, the old EF 300mm f/4.0 L IS USM worked quite well even with my 5D4. Interestingly, my old EF 500mm f/4.5 L USM from 1995 worked still surprisingly well with my R7, in contrast to my 300mm, a lens that was introduced in 1997.As for why your EF 300mm f/4 L IS with a 1991 design isn't as good with newer MILCs, please see Roger Cicala's old blog entry Autofocus Reality: Part 3B from back in 2012. He explains that Canon upped the game around 2010 as to how accurately the lens reports the focus position to the camera.
Yes but this doesn't explain the light dependent behavior, noise (and contrast on the AF sensor) does.The baseline for an APS-C DSLR camera is narrower due to the narrower semi-silvered portion of the narrower reflex mirror.

Yes, I agree. I actually prefer the file I get out of my R6ii to those I get from my R5. The resolution choice of 24mp was to buff 4K video (yawn) and the bump to 33mp in the mkiii was to assist 8K video (double yawn). So none of these choices were made for photographers needs in mind. It was all about the hybrid / video sales. If the R8II is truly an enthusiasts photographer’s camera, then let’s hope Canon truly hit that specific target.I´m struggling with that assumption. As posted in a different thread:
Canon could easily reuse the 24mp sensor for the r8ii and use it for further market segmentation with a 24 - 33 - 45 mp line up. I´d actually expect them to do just that.
You could also replace the Nikon Z6 with the Nikon Z6iii which is a fairly good wildlife option in and of itself. Yes the R6ii and R6iii even without a partially stacked sensor are marginally better, but its minuscule differences at best.I have been waiting for the R7MKii to replace my 90D. I could not see going to the R7 as it was not much of an upgrade for me and I do have a R5 as well as a Nikon Z6. For my wildlife photography (the majority of my photography) I use my R5 with a RF100-500 and RF200-800 along with my 90D with my EF 800 f/5.6. I was hoping for the R7 MKII to upgrade this. Since the delays in the R7 MKII I have been looking at the OM System OM-1 MKII for more range and better performance than my 90D. Looks like I will be adding the OM-1MKII to my camera systems and keeping the 90D for a while. I could even go to the OM-5 MKII and have an upgrade over my 90D and better performance over the R7. Canons marketing strategies has lost them another customer and longtime Canon user. Also, since I use the Nikon for street and travel photography, I can get rid of that and just use the OM System to cover all my photo needs.
I think a lot of people do jump to zooms when the differences in cost and comforts converge appropriately. I think even the modern 100-300 2.8 pretty much well splashes writing on the wall for any similar prime, right? Like for the same cash, more or less, why buy a 100, 200, 300 2.8 prime when all can be had for prime like quality and zoom convenience? This ever has been Canon's long term direction, I think. For good reason.However, Art Morris's website, birdsasart, was very influential and he was a staunch proponent of the 400 prime, and he initially ran down the zoom. But, eventually he changed his mind and went over to the original zoom.
Haha! For the love of life, Art — WHY?Mind you, he was one of the first to go to Nikon and then Sony. So, you are not right!
But so marginally in terms of the mark I, and who shoots animals or people in the lens corner? Kind of like maybe this truck tows more than that truck in the same class, but then one might also consider sway control. Even with the zooms available and evolving rapidly. And even when the II came out big names still talked-up the prime for beginners. Some examples:The first version bettered it
The Canon EF 400mm f/5.6L USM Lens is popular for bird photography and especially birds in flight as it offers lots of reach for a reasonable cost in a relatively light package. Good vignetting performance helps keep even blue skies as they should be - evenly blue. Other uses include general wildlife photography and well-lit field sports.
Well, yes — but that didn't stop people from promoting the prime for beginners. Let's consider:the magnificent EF 100-400mm II rendered it totally obsolete.
Bold emphasis is mine.The 400 f/5.6L has been in the Canon lineup for 5 years longer than the original 100-400 L IS, yet it is a good performing lens with image quality essentially equivalent to the 100-400 L II and less distortion (compared at 400mm). The 400 f/5.6L is lighter, longer and considerably less expensive [...] I find the zoom to be a far more useful lens.
This lens fits in even my smallest and lightest travel kit, and I have confidence when using it wide open that it’s going to give me excellent performance. Sure, I’d like it to be an f/4, but the extra weight and bulk wouldn’t be welcome. [...] I definitely miss Image Stabilization, and wish that Canon would re-issue this lens with IS, but since I will be using it tripod mounted 90% of the time it’s no real hardship.
And just because I wanted to know, we tested the old, but excellent Canon 400mm f/5.6 L prime lens, for comparison. Few people shoot it anymore, but there’s a reason it’s remained in production for decades. It’s not quite as good as the 100-400 IS L, but still, an excellent performer considering how old the design is.
I 100% agree with you about the hassle and comforts. And cash being no issue your argument wins every time.The 500/4.6 was OK for BIF when you are at 1/3200s and don't need IS. But for hand held shooting in other than good light, a tripod or support was essential, and if you have ever tried to focus a hand held 400mm lens without IS, it is very difficult as the image darts all over the view finder.


There are still 8 more months to come, and, why not, a 14 TSE, a 20-70 L, new big whites...TBH, I don't see any "fault" here at all.
@Canon Rumors, @Craig:
You get bits of information, you interpret this, and then you share your conclusion with us.
Rumors are rumours, it would be quite boring if they all became fact the moment you spread them.
OTOH...
Those two are quite boring to me. And I already shared my thought, that I don't like the R8(m2) being hijacked for a retro style cam.
Make this retro cam a solitaire, make it unique, especially in its name (RE-1 was a no-brainer to me, just great!) , then even I would like it - but still won't buy it.
But please don't take away the product line of a small modern (!) FF entry camera, with modern egos and so on.
This was the one cam I was interested in.
Looking around, seems that 2026 is becoming more and more disappointing, in any facet I can think of... meh.
The R7 was released years ago already and still no direct competitor from Nikon.The R7ii has far better odds even if it's likely late 2027.
Mmmmkay. Every RF lens is focus-by-wire, so I'm not sure there's a point being made. But...thanks??In other words, it's a focus-by-wire lens.
I found the RF 14/1.4L VCM to be exciting, and I'm hoping for more good lens announcements this year.Looking around, seems that 2026 is becoming more and more disappointing, in any facet I can think of... meh.
Sure, I'm one of those people. The 50/1L, 85/1.2L (and the second version of that lens), 200/1.8L, 300/2.8L, 400/2.8L, 500/4.5L, and 600/4L all used focus by wire. And they all had the same problems when they went out of service and eventually the AF motor supply dried up some years later. There were a few third party services that converted them to MF or rebuilt the AF motors, I'm not sure if anyone is still doing it now.There are more than a few Canon users who have been around long enough to remember what happened to their focus-by-wire EF 200mm f/1.8 L USM lenses when Canon started running out of repair parts for the USM motor shortly after discontinuing the lens. They became impossible to focus and nothing more than paperweights if the AF motor ever broke. The EF 300mm f/2.8 L, EF 50mm f/1.0, and EF 85mm f/1.2 also used focus-by-wire manual focus, but there wasn't the same kind of parts shortage until years after they were discontinued.
I think that depends a lot on how the PZ functionality is implemented. I'm not familiar with Canon's RF PZ systems to date, but I would hope a Canon L lens with PZ would work similarly to Sony's 16-35/4G PZ.
Sony put six of their fastest XD Linear motors into the 16-35G. Four for focusing (2 motors x 2 groups), and 2 for zooming. The result is that the zoom ring has the same feeling and performance as the focus-by-wire system. You can twist the zoom ring really quickly and get really fast zooming, or you can twist it slowly and get slow zooming. The ring is also not a rocker, you turn it the same as you would a mechanically coupled zoom ring, though there are no hard stops AFAIK. Basically, the zoom ring works like the focus by wire MF ring does.
You can also use the zoom rocker on the lens or camera to get smooth constant zooming for video. You can actually set up the lens' zoom responsiveness from within your camera's menu, too. Zooming and AF are both silent, as usual from an XD Linear system.
Another benefit is that the zoom and AF work in concert to maintain perfect focus when zooming, with no delay. It makes the lens appear to be completely parfocal.
As far as zoom lag goes, it's also about the same as what you would experience with a very high end focus by wire system. I suppose if you want to rack the zoom SUPER fast it woujld probably be faster to crank a a mechanically coupled zoom really hard, but the PZ is not slow or laggy.
If Canon implements something similar to this, I think most photographers who are likely to buy an f4L lens would find it very useable. Certainly anyone who wants it for hybrid use will appreciate it.
I nearly said something similar but they may well mean it colloquially (as in "old and out of touch").I hate to break the news to you, but none of the boomers are middle aged any longer. Those born in 1964 are turning 62 years old this year. All of the boomers will officially be "seniors" by the end of this year. In most places, they've been considered "seniors" since they turned 60 in 2024.
Have a look at the only other PZ lens, the RF-S 14-30mm F4-6.3 IS STM PZ. PZ means the zoom motor is inside the lens, not in a separate accessory. The zoom ring has no manual function. Turning it one way or the other just activates the built-in zoom motor (in a force-sensitive way so the zoom can be driven at different speeds). Personally, I would not want a zoom lens with only a motorized zoom function for photography. YMMV.
The third time I'm happy for basically the same post.
Having IBIS might be a sign of Canon making this one more photo-focused and less vlogger crap. This will make many middle aged oldschool boomers like me happy.
And it will make it a reasonable secondary/backup camera for those who haven't seriously considered purchasing one. Until now.
