There are few things photographers can find to agree on, and a vast ocean of things about which we disagree. Like the great dividing subjects through the history of mankind – light or dark beer, under vs over toilet paper rolls, Tomcats vs Hornets, and Jason Mamoa vs Blake Shelton – the choice of favorite lens is a choice that puts you on either side of a line in the sand.

Regardless of what side you’re on, if sales, page views, comments, discussions, variety, bar-brawls and divorces are any indication, your favorite falls into only one of 4 beautifully difficult choices: 35mm primes, 50mm primes, 85mm primes, and 24-70mm.

The question is, which side are you on?

Well, whatever the choice may be, we’ve gone through to find the primary of each of those lenses currently on sale this holiday season, and here are the 50s. Some of these lenses are up to HALF off.
