So I just picked up a Nikon 50mm f/1.8D and was curious how well it performs when stacked up to the newer 50mm f/1.4G version. At f/1.8, it’s not very sharp and it has very low contrast compared to the 1.4G version. The 50mm f/1.4G is stellar even shooting wide open at f/1.4. Still not as contrasty at f/1.4 but usable. Just look at the results below and judge it for yourself.
