This is a lens review for the Olympus 75mm f1.8. This is a great first fixed focal length lens to get though the 45mm f1.8 is cheaper and you may want to go that rout instead if your are cash tight. With the 75mm f1.8 you can capture a lot of great things and you can easily spend two to three years to capture all the things in the sky that this lens can frame up.
