I have a few questions for anyone with a Sony A7RIII. I currently take my photos on a canon 77D. I use it as a hobby for car photos but also use it for senior portraits, family photos, and such for a little money on the side. I would like to get a G or GM series lens right away with the purchase of my A7RIII. The lenses I have narrowed it down to are the 24-70 or 70-200. I currently use canons more expensive 17 to 55 for automotive rolling shots and portraits. I use the 55 to 250 for automotive stills. My question is which lens should I get for the A7RIII and if I plan on eventually stepping up to a G master is worth it to just get one right away or buy two of the lower end lenses. Any advice would be helpful at this point. I just want someone to help away me one way or the other.
