Purpose:
1. Suitable for wedding?
2. Corporate events?
3. potrait shoot?
For the past few days in Rome and Florence, I have been trying to "primed" my 24-105 by shooting at 24, 35 and 50 to give myself some new challenges. Why don't you try it on your 24-70 for a month and find out for yourself? It's a good and free attempt to answer your $2k question![]()
So, care to share which one did ya finally choose?![]()
Sigma 24 1.8 isn't HSM.
You'll probably have a hard time focusing in low light. (AF hunting - like a Canon 50mm 1.8)
AF hunting (or not) depends more on the sensitivity of the camera rather than the AF mechanism (USM/HSM or not).
Both are major factors. Try using a 50 1.8. in lowlight even on a 7D.
Wanted to throw it away. lol. My 17-555 2.8 and Siggy 30 1.4 AF are much much faster in locking on.
Thing is all these lenses would hunt but the USM/HSM lenses do them much faster.
