What is the difference between DC and DG Sigma lenses?

DC lenses are designed for cameras with an APS-C size sensor and won’t cover the entire image area of a 24x36mm (Full Frame) sensor. DG lenses are designed for cameras with a 24x36mm (Full Frame) sensor but will work equally as well on a camera with an APS-C sensor.

What does APO mean on a Sigma lens?

How good is the image quality at 300mm?

Image sharpness with the lens stopped down fully (ƒ/22 – ƒ/32) is surprisingly good until around 133mm (~3 blur units). At focal lengths longer than that images are uniformly soft, but in the case of 300mm, image quality is a bit more evenly soft than at wider apertures, where the corners are off the charts for softness in comparison to the center.
