I just got an email from Borrow Lenses that is it time for their annual used inventory blowout aka their biggest sale of the year! Get 20% off all used gear with this code - USEDGEAR20. If I wasn't saving money for Disney World, I would be ALL over this! I love renting lenses from them when I need something for a wedding or family portrait sesh.
Good luck purchasing the best lens for you! I'll be uploading pictures later from Harper's kindergarten graduation; can't wait to share these with you!
