I'm starting a new series I've decided to call Project 105. I chose that name simply because all of the photos in the series will be taken with my Sigma 105mm Macro lens. The Sigma 105 is a true macro lens meaning it can produce images at a 1:1 life size ratio. Many lenses have a macro "function", but technically aren't true macro lenses because they cannot produce the 1:1 ratio. That aside, many of the photos I take with the lens are not macro. The Sigma 105 is a fantastic short range prime telephoto. I don't do much in the way of portrait photography, but many people who do like using a lens like this one. It's a very sharp lens and also my fastest with a maximum aperture of f/2.8. It's faster than even my Canon L series lens.
Because it's a fixed focal length, the lens forces me to move around to get the shot I want rather than relying on zoom capability. If you ever find yourself in a photography rut, one thing you can do is use a fixed focal length lens and force yourself to shoot with it for a day or a week or whatever time frame you determine. Limiting yourself to something like a fixed focal length can actually make you see things differently.
At any rate, here is the first in my Project 105 series. And I'll be continuing my On A Stick project, too. I wanted to have something new to work on when I'm not working on the stick series.
