Thank you for the tips! Very much appreciated, and absolutely! No wider than f/4.5 for group shots, if not smaller with good light
I totally agree and am committed to practicing with something new before I actually put it into practice.
You've got the 135 f2 so you know! Its way exaggerated on telephoto, but even at 35mm it can be demanding.
I'm just saying that narrower is safer until you've got it dialed in.
4.5 fine if the light's there. The shot I posted above was f3.5. Much narrower and I'd be hurting for light.
