I'm not sure I'd disagree with the idea that a really good 35/1.4 might not be a reasonable choice for a lot of situations Maybe A7Riii for the body. I don't have either and if given $2500 (a rough guess looking at KEH for the used 35/1.4 and A7Riii in reasonable conditions), that's probably not what I'd rush out to buy.
Without some parameters, it's not really an answerable question. And there's a good chance, in my hands, quality image and image quality might well be rather different things. I think there's a potential disconnect between holding a budget limit and "best image quality."
It's like "What's a good budget car?"
Let's say the idea is, $5000. Taking "landscapes" from the South Rim of the Grand Canyon. Now, your $5000 budget including the camera, lens and small bag, has to get you a car, and take the four of you from San Francisco, over Tioga Pass, down Highway 395 to Lone Pine, east through Death Valley, then Las Vegas, then on to Williams or Flagstaff. On a Fourth of July weekend.
