What would you use the 24 f/3.5 for that requires macro? The distance between the front of the lens and the subject must be extremely small.

I think their 14-24 and 24-70 F2.8 would make a huge impact. From all the reviews I've seen it seems especially the latter is as good as all the "native" mirrorless 24-70 F2.8 (which are all amazing), so having that at $1100 would be great over the RF.

I'm just glad that Sigma made their lenses for L mount which has the same flange distance as RF. The Tamrons for FE might struggle with that depending on the design of the back element.
