If there's one thing I've heard mention quite a bit is people's wish for a long focal length macro lens. In this patent application (2024-103311), Canon is exploring just that. I haven't seen many patent applications in this category, so maybe it's a sign of good things to come. According to Canon; In optical systems

I guess many macro shooters would appreciate a modern version of the old 180mm f/3.5 Macro, this would be quite tempting for me, too.

But a true 300mm f/4 macro would be even more attractive for me personally. I used my EF 300mm f/4 a lot for more shy objects like butterflies, but such a lens with the option to get really close w/o extension tubes would be mouth watering for many macro photographers, including me.

Let's goooooooooooooo!

I've used the EF180L extensively this summer on both the R7 and R8, both for stills and video. For smaller dragonflies and regular sized damselflies I'd like a bit more magnification, the 1.4:1 of the RF100L is great on full frame, but the working distance isn't well suited to warmed up dragonflies. The 2:1 180mm variant would be an awesome replacement.

I immensely enjoy the 1:3 of the RF100-500L, the 1.2m working distance is a good compromise. Due to focus breathing it's a 300-ish mm lens at MFD, so that 300mm F4 variant looks very interesting! I'd likely keep the EF180L, I routinely run out of space when trying to photograph insects and amphibians in or near water. Maybe I should 'invest' in a pair of waders :)

And as @Besisika said: 8k for macro would be awesome, the handful of experiments I did with my R5 with 8k had impressive detail and turned into great 4k output. My Intel CPU iMac did not like that, however.

That is true. I use it very sparingly, and some insects should be in that category, especially when you shoot it only while on vacation.

A 300mm f4 1x macro would be a wonderful lens for very small subjects at a reasonable distance. I enjoy "butterfly on leaf" type of shots, and the RF 100-500L (which I have) at 500mm might give similar (or better?) results for it as this lens, which would have to back away from max. magnification for a wider subject in view. I don't shoot many things down to 36mm wide, but maybe a lens like this would encourage me to do so, as I'm sure that the resultant image would be truly spectacular. I wonder how close the subject would have to be to the lens front element to get 1:1, and how close to the lens hood it'd be if one used one? The 100-500L with lens hood can still be far enough away to not scare away a lot of things that this lens with lens hood might scare away?

Better late than never :D. As others have noted, the 300mm f4 macro will be great for insects like butterflies and dragonflies with a reasonable working distance. I use the EF 180 mm macro with a 1.4 extender on the R5 so this lens would be even better. A 300 mm f4 macrolens will be less universal than a 180/190 mm that takes extenders (size and weight, working distance).

I bought my EF 180 mm lens in 2003 and it has earned it’s retirement. So Canon, hurry up!

Good question. The old EF 300mm f/4 has a magnification of 0.24 at a closest distance of 1.5 m. Unfortunately, the data given here do not include any information about a closest distance, but I'd guess it would be well below 1 m. That said, I don't think that it would be so close that the hood would start to be a real problem like the quite long hood of the EF 100mm f/2.8 L IS USM. I use that lens nearly always w/o hood, because that one really threatens to scare away any insects.

Another point is that you do not always need to frame an object 1:1, since highly resolving sensors give you plenty of room to crop. So, if you realize that a butterfly doesn't tolerate the closest distance, even a magnification of 0.5x would be great.

RF 180mm - well, i assume this has a higher prise similar like all other RF lenses.
I use a Sigma 180mm EX f/2.8 HSM OS Macro and this is a heavy glas with an exzellent Sharpes. I use this in combi with an ef adapter with an R5 and R. If i need more zoom, i use the 80d. Sometimes, the EOS 5ds will also used for macros - especialy inhouse.

a 300mm f4 with extenders could be used for some birds for people interested at everything while hunting insects !! :)
I spend much of my time shooting birds and insects, and for me the RF 100-400mm or RF 100-500mm would be far more useful and versatile for everything. But YMMV.

The versatility of the 100-500L has been a major reason that I keep using it (without teleconverters, and cropping when needed). I'm not one that mainly uses the max focus length, but instead mostly vary the focus length across the entire range (due to the varying size of the subject I want). The 5x zoom is so valuable to me that I fear that if I got yet another fixed lens (however spectacular it is) like a 300 f4 that I might end up not using it much and it'd stay on my shelf while I still have the 100-500 for almost all of my telephoto shots.

With all of that said, I do want to try the 300 f4 when it comes out. Maybe the 1:1 at 300mm would impress me so much that I would feel that it's worth getting it after all. It would all depend on if I want to get into the world of extreme magnification, and if the subject to lens surface at 1:1 was long enough for usage with live subjects without scaring them away.

My requirements are minimal and I am a rank hobbyist. 1m/yd is as close as I can usually get to an insect without scaring it way, and all I want is sharp image of the full butterfly/dragonfly/insect, and the difference between 0.4 and 1x magnification makes little difference to me. I can see that some enthusiasts would like the extra magnification and do get immense fun at resolving very fine details. @entoman who is a professional butterfly photographer (no longer on the site) went over to the RF 100-400mm as his main lens.

I've enjoyed the luxury of having 2 RF bodies, having the 100-500 on one and a 1:1 macro on the other is great when aproaching skittish subjects. Mount the 100-500 on the R8, get your shots, switch to the R7+macro to get even tighter close-ups.

Yes, ur right. more than one body is very comfortable. You don't exchange the lense outdoor. I use the R5 and R; somtimes the 80D and 5Ds and 5DM4. Dependet on the pictures i wannt to do the focus.

I have previously (and currently) had just a single (R5) body. Now that the R5 II has come out, and looks like it is worth having, I'll go ahead and trade in the R5 (for whatever pittance I get) to get 2 R5 II bodies. I've always wanted to have 2 bodies so I could mount 2 main lenses simultaneously so I could go out and not have to swap lenses. That'd allow me to enjoy shooting like you've suggested with a 100-500 and a 300 f4 (if I get it) for example, or more often a 100-500 (or 70-200) on one and a 24-70 (or 15-35) on the other depending on what I wanted to take photos of. I like the idea of only knowing one menu and button interface with 2 identical bodies, and I want them both to be full frame to match the full frame lenses. I can crop them afterwards if I want further reach and that's OK with me.

I haven't taken it in yet how different the R5 and the R5ii ergonomics is. Are they similar enough to keep the R5 as the second body?
