So I've acquired some new lenses, and will be getting rid of some.  It seems a never-ending process tweaking your equipment to get the perfect mix of gear.

I got a Sigma 150 macro lens, because I wanted a little more reach than the Canon 100 was giving me.  My wife has the Sigma 105, so I still have access to a lens of around the 100mm focal length if needed.  And I still have "the beast" - the Canon MP-E 65.

Took the new Siggy 150 out on the weekend for a bit of a workout.  Must say, it's very nice.  See some of my recent dev's such as:

Also bought the Canon 35mm f/1.4L and the Canon 85mm f/1.8.  Both with a view to doing more low light and portrait shots.  Got a baby on the way, you know  
Getting some umbrellas and other strobist off-camera lighting gear for Christmas too.  Looking forward to trying it all out.
