It seems Sigma can do no wrong with their latest series of Art lenses. Honestly, we are quickly running out of accolades for them. This latest addition, the full-frame 135mm f/1.8 DG HSM, is another winner in a growing list of amazing prime lenses. With its compressed perspective, the medium telephoto focal length is perfect for portraiture and weddings. You can even use this lens quite effectively for low-light sports shooting (think High School volleyball or basketball) due to the redesigned high-torque Hyper Sonic Motor.

Make sure you nail your focus point, because this lens will not let you get away with a focusing error. The depth of field while shooting wide open is razor thin. But if you're looking for creamy out of focus highlights (commonly known as "bokeh"), this is the lens for you. Busy backgrounds are not really an issue when you can make them virtually disappear. Yes, it's big. Yes, it's heavy. But boy, can you use it to create stunning photographs. Rent it today and take your portraits to the next level!
