The SL was manufactured 5 years prior to the A7S III and that is quite a large gap as far as tech is concerned. Each of the cameras come with the identical body type (SLR-style mirrorless).

Before delving through a in-depth comparison, below is a short introduction of how the SL grades versus the A7S III in the way of portability, imaging, features and an overall rating.

Usually, it is very hard to visualize the gap between sensor sizing merely by checking specs. The photograph below may offer you a greater sense of the sensor dimensions in the SL and A7S III.

As you can plainly see, both cameras have got the exact same sensor measurements albeit different MP. You should expect the Leica SL to give extra detail due to its extra 12MP. Higher resolution can also enable you to crop pictures much more aggressively. The older SL is going to be behind in sensor tech.
