Judging by the number of questions I get from photographers concerning the working distances of macro lenses I think it is a good subject to talk about.

The working distance of a macro lens, not to be confused with minimum focus distance, is the distance between the front of your lens and the subject. This is different from the minimum focus distance which instead means the distance to the subject as measured from the focal plane mark on the camera body, not from the front of the lens. Working distance is a more important figure since it tells how much space you have between the front of your lens and your subject. Working distance generally increases with longer focal length lenses, shorter lenses usually have shorter working distances.

Spots where sand, sea, and sky come together offer certain challenges to photographers, but the results can be so amazingly rewarding. Conditions can change quickly as the sun hides behind a cloud, and conditions most certainly change slowly as the tides sink and rise and the sun and moon dance across the sky. The same patch of sea may be mirror calm and reflecting golden light, or it may be a churn of furious waves. Fogs, mists, and wind-whipped sand can make for gorgeous images even as they fool camera meters. There’s a world of possibilities waiting to be captured along these edges, whenever you visit, and with whatever Sigma lens you’ve got in your bag.

Seeing the seasons with the Sigma 150mm F2.8 EX DG OS HSM APO Macro

It’s now officially Autumn here in the Northern Hemisphere. The days are getting shorter and hillside stands of trees are bursting into colorful displays of crimsons and golds. Obviously, it is a great time for ultrawide landscapes to capture those sweeping vistas. But it is also prime season for packing a telephoto macro lens like the Sigma 150mm F2.8 EX DG OS HSM APO Macro to capture the grandeur and spirit of the season in its tiny details.
