This would be a lens that has my attention.

It would be a nice travel lens. I think it would sell quite well if the price was reasonable. Good for the crop sensor cameras.
I’ve a suggestion a new Canon RF 75-300mm f/4-5.6. They could call it Canon RF 75-300mm f/4-5.6 II and that name would be the only thing they need to change.

not really, also where is the bubble? a lot of AI is satisfying a real need.

"Bubble" is in that we see advertisements suggesting "you can get rich if you learn AI NOW!!!" and the commercialization of pastiche-like "creative" software. Eventually, people will realize they can't get rich so easily, and pastiche is pastiche.

Beautiful flowers. Nicely done, ISv.

Not filling the whole image circle. What's next? Filling half of the sensor with AI generated image?

I'm still waiting for someone to demonstrate in the final image the inferiority of digital geometric distortion correction, compared to optical correction that some people claim is superior. I tried and failed, finding that digital correction was just as good. Since you clearly believe that optical correction is better, perhaps you'll be the one to actually show some evidence to support that belief?

I won't hold my breath.

This makes me VERY jealous of Sony boys with the new TC compatible 100mm Macro. Or would it still not cut it?

Interesting, I have a couple of butterfly shots taken with the 200-800 but environmental rather than closeup macro. I won't ever justify an additional 100-500 for myself, but am seriously thinking about the 100 Macro. I have to dig deeper to understand what floats my boat...

Consider the RF 100-400mm. It's one of the bargain kings, and small, light and versatile.

Does anything speak against the Sigma f/2.8 zooms for video?

They have no IS. And with the R50 (or R50 V) having no IBIS, this is not a dream combination for video.

No, the working distance from the front of the lens to the subject would be way too short for skittish insects like dragonflies and butterflies. Cropping is no substitue for a long RF macrolens.

This is where the RF 100-500 and 100-400mm are so good. It's just great to have a lens you can use for both birding and dragonflies on a hike. Put a 2xTC on the RF 100-500mm and you have a good 1000mm for long distances and x0.6 at about 1m for dragonflies and butterflies. Although the 200-800mm is my favourite for birding, it's second fiddle to the RF 100-500mm on many occasions.

ah, you've missed all my lectures on the subject!

Consider a card like a small SSD, there's a finite number of times that you can write to each cell before you start to get problems. and unlike SSD's where alot of the data on them is atypically static, cards typically get their entire contents flushed and re-written frequently. Also some cards have wear leveling, and some do not. it's not something they commonly mention either.

so it's just a bad idea to keep using the same few cards over and over, especially if you use your cameras frequently and take a ton of photos or video. To be fair, this is usually measured in years of use. it's not as if they'll die in 6 months, but if you tend to fill a card, wipe it and use it again, and do this over and over - just realize there are limits - especially with high capacity cards.

it's probably a good topic to discuss on it's own - sounds like an article in there. I may have to blow up a few cards to write it.

You can use Crystal Disk Info to check the quality and wear of your memory cards (windows only).

Does a r7ii with this resolution and the rf100 macro negate the need for a long macro lens (working distance)? AF and fps would support handheld usage

I wouldn't argue with your experience at viewing high and low MP sensors output at the same size. But, when not downsizing the higher MP sensor, the wider and sharper the lens, the more the improvement in increasing MP. I really noticed this when I had both the 400mm f/4 DO ii and 100-400mm f/5.6 ii and the 90D.

Absolutely. I’ve stopped using what might be regarded as mid level lenses on my 5DS for landscape work, lenses such as the EF 24-70 f/4 L for instance, because the IQ I get from ‘high resolution’ lenses is stunning, especially when viewed at full output. But technique is also critical of course, my most important accessory now is an umbrella to keep wind off the camera !
As you noted, my comments were based on viewing high and ‘low’ res files at more normal sizes, so closer to the lower mp camera’s output size.

Oh yes, finally some hope. 100% agree. Just do it!

Using a middle of the road lens on a ‘high’ mp sensor definitely gives a sharper, higher IQ image when reduced in size to the output of a ‘low’ mp sensor using the same lens. However, if you use a really high resolving lens on both then the ‘low’ mp sensor steps up to match the reduced ‘high’ mp in my experience, at least when not shooting at the extremes of either spherical aberration or diffraction.
I agree with you; high mp is a good selling point, and will no doubt continue to increase until such a time when manufacturers can gain further sales by offering a ‘low’ mp model of about 20 mp !

I'm not really sure what the point of 40mp crop sensor is if Canon doesn't really have any dedicated high-end APS-C lens ecosystem. Best case scenario, such a high res aps-c sensor (high pixel density) is optimal with the latest 70-200Z and RF 24-105 2.8 or other super high end lenses... i mean sure you can use this with any lens, but at that point, what's the point in getting this body other than to say you have the latest and greatest Canon crop camera.

This is the reason why Canon is the only (full-frame) company making this type of camera (mid/upper range crop sensor): it is a specific tool for specific needs. It will mostly be bought as a second body to a full frame camera, hence the absence of specialized APS-C lenses. As others wrote, if you crop a lot and value pixels on target, such a high-performing crop camera makes perfect sense. Birding, macro, astro should be the main uses for it. It (may) not target lower weight or cost reduction as is usually the case for R10 und below.

The alternative is a very high MP count camera with high price and where you don't use much of the sensor: the R5II gives around 17MP in crop mode. The current 33MP R7 has 40% more linear resolution than that.

This would be my lens for the holiday bag. Used the Sigma 50-150 EX II in conjunction with the Canon 17-55 2.8 back in the EOS 30D days. The Sigma was soft but very compact.... always hoped the y would bring a sharper version on RF

Sounds like a pretty boring upgrade, similar to the EOS R6III. From 33 to 39MP isn't that big of an upgrade, but at least they finally compete with Fujifilm. I wonder if Sony will still trail behind with 26MP.

I'm all in for boring updates, now the kinks of the RF systems have been mostly ironed out: body ergonomics of the R7 are one of these kinks and really hope they use the R6 body. The MP count upgrade won't be the focus of the Mark II, but its speed: a jump from 33 to 39 plus a faster scan is a huge upgrade sensor side. Personally, I would prefer they stick with 33 but really kill rolling shutter.

I could be wrong, but fairly sure that Canon has actually opened up the R mount, in APS-C format, to third party lens makers.

Using it with the RF100 macro would be one big reason to buy it for me. You would have an effective 160mm f4.5 lens, close enough to 180mm f3.5. Also the 100-500 would have more apparent magnification at close range. For me those 2 lenses together (which I already own) would make the R7II worthwhile if it is any good. A 39mp pixel density would be very similar to the OM1. 39x1.6x1.6 = 99.84, 24x2x2 = 96 full frame equivalent.

I use the 100-500 frequently for macro type shots. The RF 100-400mm is even better.

Some people underestimate it, as is clear from comments here.

I just have one statement for this patent application (2026-003099), Canon, please, just: Do it With the Canon EOS R7 Mark II on the horizon, the zoom with a fast aperture but around the focal lengths necessary for a crop camera would not only be welcomed, but really, it's necessary. Someone was commenting to me […]

I don’t get your point. Every Canon Lens fits this. You don’t need dedicated APS-C lens to make it work.
