Mirrorless Cameras (MILC) and Lenses

OTOH the 24/1.4 has highly distortion and needs to be severely corrected for rectilinear viewing.

Is whatever Sigma 70-200/2.8 all that fragile or sensitive to heat/humidity?

As with all things Sigma, it's bulky AF. It's forgivable for an everyday walking around 24-70/2.8 but the long lens is an extra-special complication.

AF was never the strong suit of Sigma.
Have you ever used the 150 or 180 HSM macros, the last ones before OS?

 

[Mercutio]

I think the only non-stabilized EF/RF lenses I have are my Sigma 50/1.4 and Canon 100/2.8 Macro.

The Sigma tele macros had super slow AF on natively EF DSLRs. They are actually a little better on MILS.
I don't know the AF issues with the Sigma 70-200/2.8, but the Canon RF 70-200/2.8 Z would be better in almost every way.
