I recently wrote a guest post for Casual Photofile titled, “If a lens vignettes but nobody sees it, did it really vignette?”
This post was a companion piece to my Voigtlander 28mm Ultron Vintage ASPH V2 review.
In this day and age, I really dont know what the answer to that question is but it really is important to consider whether paying thousands of dollars extra for a lens, or foregoing a faster lens is a smart way to avoid pushing a button in Lightroom.
Here is a link to that article.
