Hi on August 13 at 9.30 am I will have my turn to visit the Lower Antelope Canyon. I own a Sony alpha 7 III and I'm torn between using my Samyang fe 18mm f2.8 fixed focal length or the Sony fe 24-105 F4. Do you have any recommendations? Even on any machine settings, obviously hoping it's a sunny day. Unfortunately I know that the guides tend to be hasty and I would like not to waste my time, also because I think it is not recommended to change the optics in the canyon.
