Everyone likes a bargain and most everyone wants to get more for their money. High end photo lenses can cost an arm and a leg – especially when you are talking about pro level glass. This is even more true of lenses for full frame sensors because the more glass in the lens, the more the equipment typically costs to make.

But there are bargains to be had still, if you know where to look. The Sigma 15-30mm ultra wide lens for full frame cameras is the most underrated full frame lens I have in my entire DSLR inventory. It produces great images, the lens is made of metal, and I picked it up for under ($500 NZD)
