Just about any camera will give you good photos if you know how to work the settings and not use P or Auto.
The lens flare is real. I shot that with my AE-1, and I couldn’t look through the viewfinder as I shot. So, I set the focus manually based on the scale on the lens, then I bracketed the focus and took two more shots.
I did clean it up in Gimp a little bit, because the print I scanned it from was about 20 years old, but other than that, the pic looks exactly like it came out of the camera.
