I was looking for recommendations for body and first lens option. To start, I plan to shoot astro, landscape, street photography. I eventually want to move into portraits down the road.

For the body, i was going to go with a7iii since it's on sale at best buy. the iv is as well but i figured i could use the difference and put that to lens options (build up full frame lenses). Out side of video which I don't really plan on doing (maybe a little), would there be any reason to consider the iv right now? I just figure going iii and spending more on glass was the best option.

Now for the lens. I am picking up one lens to start. I was looking at the Sony 20mm f/1.8 G or the Sony 16-25mm f2,8 G. I was leaning to the 20mm because I saw others really love it and it's on sale with now for 750.

Any advice would be greatly appreciated
