C300: to go lens for C300MK2 24/105 or else?

[AlainAlain]

I am going to do a quick compare test on the C300MK2 between my old 24-105 and a 24-105 Sigma Art, or are there better options on the market with AF?

the 18-135 stm lens is cheap but a good run around lens - silent and quick af, better i.s. than the 24-105, wider and longer range, similar image quality, just a little bit slower but the 24-105 isn't constant f4 anyway unless you use it wide open. On the flipside manual focus is pretty crap with focus by wire

For tripod/rig the 24-70 F2.8L II looks really good wide open and has very quiet and fast AF on the C300.2.
