More Sigma 50-150mm f/2.8 EX DC OS HSM Lens

Here are some shots examining the close focusing capabilities of my new-to-me Sigma 50-150mm lens. The subject is a Bee Balm blossom nearing the end of it's life span.

This first shot is manually focused at the lens' closest focusing distance:

The second shot is identical with the addition of the Canon 500D screw-on closeup lens which allows the lens to focus closer:

This is a different blossom at a different angle but also at minimum focusing distance with the 500D closeup lens:

A Hummingbird Moth was flitting around at this point but it wouldn't let me get as close as I needed to be in order for the lens with closeup lens to focus. So I removed the closeup lens and used the lens alone. This isn't really all that close, although you can see that it's not really at the lens' closest focusing distance.

To achieve greater magnification for shots like this I'd have to add the Canon 1.4X extender which lets the lens retain its minimum focusing distance but extends the focal length from 150mm to 210mm. For even greater magnification I could combine the extender and close up lens.
