Lots of pics today!
The cool thing about Macro is the very shallow depth of field. All it takes is a slight sway for things to be out of focus. The Macro photos were all taken between about F/9 and F/11. So you can see how small the area is to work with! Also the bokeh on the 100mm macro is nice and creamy (like buttah!)
This red mite spider was teeny tiny!! Probably only a few millimeters at best. You can clearly see the limited DOF here.

Here also, I just had this guy in the right spot. If you look past him the brick wall is unrecognizable as brick, and just appears as shades of color.

The area of bokeh is small here, but I cropped it wide so you can still see the out of focus leaf in the background.

This photo, while it looks mainly black, is actually a bunch of leaves from a tree behind this leaf! They were just so far back, most of the light didn't hit them, and they barely showed up as bokeh. You can see a small bit towards the bottom that appears dark green in the shadows.

The following two photos were taken with the 50mm f/1.8. If you look at the highlights in the bokeh, you can see that they have a shape (looks 5 sided). This is from the blades that form the aperture (like Danielle was saying). They don't show up as much when there isn't a lot of contrast in the OOF area, but here it's quite obvious.

Here's another one, in the highlights in the bushes, you can see the shape from the blades.

This isn't a great example of bokeh, but I liked this picture and thought I would share it anyway. Cossie got a new backpack to carry his treats, toys, water and sometimes help me with the fruits and veggies I get at the market when my hands are full. DH and I took him for a walk with it on him today to get him used to it. They were suppose to send me black though and I ended up with green! :) Taken with the 70-200 f/4L
