Using the Rare Canon 50mm f/1.0 and Its Bokehliciously Thin Depth of Field

The Canon 50mm f/1.0 was the fastest SLR lens in production before it was discontinued in 2000 and replaced with the f/1.2. There aren't too many copies of this lens floating around on the used market, so photographers who want to use the ridiculous aperture it offers must pay a hefty premium in order to purchase one; the lenses commonly sell for two or three times the original retail value.

When reader Bryan Soderlind switched from film to digital a while back, he decided to splurge and go "all the way" by buying a 50mm f/1.0 for a little over $3,000 -- a relative bargain. The lens was in "impeccable shape" and was in focus even when using the razor sharp depth of field at f/1.0. Here are some of his thoughts on what it's like to use the lens, and some sample photos from his shoots.

Lens Diffraction and How It Affects Your Photos

Really more useful for landscape and macro photographers who are going to be shooting through very small apertures (f/22 and above), this video from FStoppers explains what diffraction is and how it can affect your shots. The trade off, as they explain in the video, is between a large depth of field and a sharp image; and the trick is to find your "sweet-spot."

Samsung Might Give Compact Cameras Shallower DoF with Second Lens

A compact camera probably isn't the first thing someone would grab when looking to make a photo with an extremely shallow depth-of-field, since the small aperture and small sensor limit it in this regard. That might soon be different: a recently published patent application by Samsung shows that the company is looking into producing achieving shallow depth of fields with compact cameras by using a second lens to create a depth map for each photo.
