The war of the 24 mm - Sony vs Canons

This text will compare the following four different lenses at 24 mm aperture:

• Canon FD 24mm 2.8
• Canon EF 24-105mm L
• Canon EF 17-40mm L
• Sony 18-55mm kit lens

First the Center crop:

Note that the Canon EFs are wide open at f/4, because of heavy vignetting caused by the adapted when closing its iris control. We'll have a look at the effect of the iris in a follow-up post.

The results shows again the lower quality of the Sony 18-55 kit lens compared against the Canons. Unsurprisingly, the FD 24mm prime is the sharper of the bunch, and maintains good performance even in the corners. Amongst the two EF zooms, the 17-40mm looks sharper and with less chromatic aberration, especially in the Upper Left and Right corners. The 24-105mm L it's a bit disappointing, considering its cost.
