A new macro lens coming in the first half of 2025

I'm curious how you have found the focus shifting on the RF 100mm macro to affect your work.

At first, I thought the reviewers were overstating that problem, so I rented it.

I have the EF 100L and really love that lens, so I was shocked when I rented the RF to test and found that the focus shift on aperture change really did have real-world consequences for me, which ended up ruining 20-25% of my shots. I don't normally focus stack, so for me, having that consistent, reliable focal plane matters a lot.
I haven’t noticed the focus shift and reports on the internet make me suspect that not every copy has the same amount of shift.

For the automated focus stacking the shift isn’t an issue, for single shots with MF I haven’t noticed the effect when reviewing images. For all other shots I use the fastest fps and rock back and forth to move the plane of focus, which would hide the effect of any potential shift.

I am avoiding doing controlled tests, since those made the loathe the EF100L and stop using it. Ignorance is bliss in this case :)

Also canon has some crazy things with IS and macro lenses so anything is possible. Canon engineers do not lack for innovative solutions.

They have some crazy things coming. The core lineup is almost done for the most part. Wide prime, fisheye, tilt-shift.

Yes, yes... I know people want a rectilinear 5mm f/1.2 with no vignetting and that sort of crazy stuff, but those are outside of the "core".

I suspect optically corrected vignetting and distortion are a thing of the past for Canon. I have mixed feelings on that, but for the lenses I actually use it hasn’t presented insurmountable issues yet.

Yeah, that topic will be debated for a while yet. Me? I'm not sure how I feel, I don't own a lens in which that is part of the design yet. Maybe the 50 1.4 will be my first, but it should be better than the 35 for distortion anyway.

For most L's Canon seems to be giving the full image circle love to the lenses. It's really just a wide angle requirement to reduce size and cost.

Keep in mind that vignetting is not just an optical issue but sensor as well. Sensor well design and microlenses at the periphery affect vignetting.

$1500 L primes is quite attractive, and I think that's what will push me into accepting the new reality.

However, they continue to not make a 28L, I should have never mentioned I wanted one more than anything. Obviously they're not making one to spite me.

No, in reality they are not making a 35 1.2L to spite ME! :cry:

I've never used the Canon 180 but as I've mentioned before, I've had two copies of the Sigma 180 OS and the image quality is delicious. The downsides are its bulk, slow AF, and the IS doesn't work very well with IBIS as far as I can tell. An updated Canon equivalent would be interesting, although I'll never be able to afford one. As others have said, something around 200mm with IS and maybe a zoom capacity would be great. Personally I prefer a wider aperture, certainly no narrower than f/4, and if it gets too narrow then it's starting to tread on the toes of the RF 100-400 (although if this is a pricy beast then presumably it'll be suitably differentiated).

Not much of a point in making a macro lens super fast aperture. A longer lens such as the 180mm macro would not seem to warrant a significantly higher price either.
Making this a >1:1 (or >1.4:1) super macro or a true macro tilt/shift lens with AF would be reasonable products to charge a higher price for.
Not true. A replacement for MP-E65 would definitely benefit from being f/2 and sharpest fully open. The DoF is certainly minimal, but that is where StackShot steps in.

Totally agree. I also have the EF 100 L and love this lens. Because of the focus shift issue I will not switch to the RF version. A new 180 or 200 mm/f 2.8 macro lens would be tempting for me, as 100mm is frequently too short for insects etc.
