Agreed regarding the Sigma art lenses. Even their 18-35mm and 50-100mm go to f1.8!!!!!!!!!!! Crazy fast, sharp, less expensive typically than Sony lenses, and don't weigh a ton.The Sigma art lenses are fantastic. I had a 24-70 and it took incredible photos. Tack sharp. In terms of third party lenses I think Sigma is the best performance to value you can buy. The Sony lenses are fairly inflated for diminishing returns honestly lol.
I agree having a sick camera is just a ton of fun. You can take photos of legit anything and it looks dope
