Sony A100 vs Nikon 1 S1 Comparison Overview

Here we are comparing two cameras with different body types: Sony A100, which was introduced in July 2006 is a Entry-Level DSLR camera with a 10.0MP APS-C sensor whereas Nikon 1 S1, which was introduced in June 2013 is a Entry-Level Mirrorless camera with a 10.0MP 1-inch sensor. As you can see, A100 is 7 years older than 1 S1. Let's see if this age difference between two cameras makes a big difference.

Despite some fundamental differences of these two body types, Mirrorless cameras are becoming serious alternatives to DSLR cameras thanks to their size/weight advantages and recent improvements in their focus speeds , which makes this comparison even more interesting.

Here is a brief look at the main features of Sony A100 and Nikon 1 S1 before getting into our more detailed comparison.

Sony A100 vs Nikon 1 S1 Comparison of Available Lenses

Which camera has more lenses?

Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Sony A100 has an advantage over Nikon 1 S1. There are 143 lenses for Sony A100's Sony/Minolta Alpha mount, on the other hand there are only 13 lenses for Nikon 1 S1's Nikon 1 lens mount.
