Vetting a lens for astrophotography can be a bit of a pain, as most reviews don't dive deep into lens performance when used on the night sky. As such, I have been compelled to create lens reviews specifically for astrophotographers, which dig into lens performance in somewhat exhaustive detail - all to uncover how the lens performs on the stars.
