More experimenting with extension tube.

[Terry McDaniel]

This time I mounted an EOS to FD adapter on my 7Ti, then the 25mm extension tube, then a Canon FD 50mm f1.4 lens just to see how it would go. First off, there is no aperture control with this setup, so all photos were taken at f1.4. I set ISO to 100, then used the shutter speed to adjust exposure. Speeds ranged from 1/500 sec up 1/3000 second. First photo without the Raynox 150, second photo with it. With the Raynox I could get to about 4mm from subject to front of lens. I really miss the split image focuser when doing stuff like this. No cropping.

Both of these were with the Raynox attached. No cropping.

With the Raynox. Again, no cropping in post.

Last two. DOF is basically non existent with this setup.

DOF is basically non existent with this setup.

I was just thinking that the DOF must be thinner than thin!
I really love the little blue flower in the second post. It's lovely.
