I was wondering: Would we ever see a Viltrox RF-EF speedbooster?

It already exists.

You can also buy an official OEM version made by Canon

is there a catch?

No.

Canon has made an RF speed booster! However, there's catch… | Digital Camera World

Look at the date of that article (September 2020). At that time, the only RF mount crop sensor cameras were in the Cinema line.

ok, thanks

I wonder if they make an RF speed adapter that would work with my RF85 f2 to make it 60 f1.4 on an R7?

My viltrox EF-ef-m speedbooster worked nice with the 100mm L >> 71mm f/2.0.

Interesting what does and doesn't work well with the Viltrox EF - EOS M2 0.71x speed booster. On my wide angle and prime lenses of 50mm or less (including the Canon EF 50mm f1.8 ii) the corners were noticeably soft until around f4 - f5.6.

But the Viltrox speed booster with the Rokinon 135mm f2.0 lens became a surprisingly sharp 100mm f1.4 lens wide open!

Longer focal lengths work better, and the 50mm full frame corners of the f/1.8 mkII aren't great to begin with....

The 100mm L macro has great corner sharpness. The speedbooster is hurting it a bit, but 71mm f/2.0 is portrait territory, and for portraits these corners don't matter.

45 is more than enough, but 500.000 isn't
