Canon 6D MII vs Sony A99 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 Canon 6D MII has an advantage over Sony A99. There are 257 lenses for Canon 6D MII's Canon EF mount, on the other hand there are only 143 lenses for Sony A99's Sony/Minolta Alpha lens mount.
