I have read a couple of related questions, but I am curious to find out if there is a list of parfocal/varifocal lenses out there.
I'm most concerned with the lenses I have and I would like to know what they are as well. Considering that other answers suggest that the more expensive lenses are more likely to be parfocal, I would like to know about the following lenses:
- Canon 70-200mm f/2.8 L ii
- Canon 24-70mm f/2.8 L ii
- Canon 24-105mm f/4 L
- Sigma 12-24mm f/4.5-5.6
