I am planning to buy this camera but would like to know if it's compatible with the Tokina atx-i 100mm f/2.8 FF Macro Lens for Canon EF that I already own. I know some non-Canon EF lenses won't work with the new mirrorless cameras. Does anyone know about this particular lens? Overall, I like the lens - it suits my hobbyist needs. Thank you!

Nope, that is correct. We of course, don't know why Canon did that, but it might be due to the SA or that fact that the focus distance is already 10" at 1:1.4.

Thank you! I'm still trying to understand magnification, but someone I know here who is heavily into macro told me that I want 1x. I don't know why and what the difference in the final image would be. If the Tokina doesn't work or work well, I will buy the RF - and it's cheaper!

As a hobbiest, I still have a lot to learn, and magnification is one of them!

Just optics and a little mechanics.
Since any lens has an "angle of view" - which is a function of focal length and sensor size. If you imagine a cone stretching out from the lens, it is pretty easy to calculate the magnification at any point along the axis of the cone.
The trick is, higher magnifications are closer to the lens, so you have to be able to focus close to the lens to get high magnifications. This is what macro lenses do.

Thank you. Still trying to wrap my head around it!

"... someone I know here who is heavily into macro told me that I want 1x."
That can be true but it is not an end all statement. 1 to 1 is generally consider to be macro. However the ad boys in the lens department tend to throw the word "macro" around with some abandon. A lot of lenses that are called "macro" can not do 1 to 1. So technically they are not true macro lenses. Beside the fact true macro lenses are designed differently than GP lenses.
All advice is not necessarily good advice. You must weigh it carefully when applying it to your specific requirements.

You have that backwards. The RF 100mm f/2.8L IS USM macro has 1.4x magnification, 1.4:1. And as of this posting, it's on sale at the Canon U.S.A. store, and probably other authorized Canon dealers. I have had it for quite a while and it is quite good. I also have the EF version.

Everything from a technical perspective was covered previously. 👍
Adding to Newton's post above.
Canon RF 100mm, (today) new $999

I did the above a few months ago ($799). Above is still a great deal. Black Friday is coming, but things can sell out fast as the holidays approach. I've learned over the years that holding out for another $50-$100 that may or may not happen is not worth missing a deal. Refurb items can go in and out of stock quickly. I hope the Tokina works out, but if not this is a great time of year to treat yourself.

LOL! I paid full price two and a half years ago, and I had the EF version. Just couldn't wait, heh heh 😉
