Quartz Crystal
It has been awhile since my last post. Sorry about that. I've been getting my son ready to go back to school and haven't had much of chance to do any photography. There is the photowalk this weekend though, and a professional bicycle championship on Labor Day weekend. So, the funk should break soon.
In the meantime, above is a macro shot of a quartz crystal I took last year after I got my extension tubes. The tubes are a relatively inexpensive way to try out macro photography without having to purchas an expensive macro lens.
Anyway, keep shooting.

Oh cool!
Thanks for sharing that... Your timing is perfect as I have been looking around, trying to find information on extension tubes. There have been times when I wished I could get closer with my 50mm lens and couldn't. The extension tubes would be extremely useful.
What is your experience with the Kenko tubes? Did you get the ones that enable autofocus and TTL metering? Or, are you stuck using full manual? I'm thinking about the possibility of picking up the set.
I like the Kenko extention tubes. The set that I have do allow full focusing and exposure functionality. The tubes them selves are a cheaper plastic than Nikon lenses would be, but then they don't cost anywhere near as much. ;-) They do have a small amount of play between them when all three are stacked together with a lens, but nothing that has impacted any shots yet. They work really well with my 50mm lens.
I do tend to use manual focus when using them just because it seems easier that way for some reason. Exposure seems to be correct with them though.
Since they go between the lens and camera, they can be a bit combersome to use regularly. However, if you aren't changing them out all of the time, it wouldn't be any different than changing lenses.
Thanks for the info. I imagine they would go very well with my 50mm f/1.8 lens as it is made out of plastic. It's a great lens, but cheaply built.
When you have the shorter tube on, how close can you focus and how far away can you focus?
If I wasn't in the market for a flash, I'd just buy these now! But, I gotta use my funds for the flash.
I have never actually measured the focus distances with the extension tubes. It does get to be very close with all of them attached.
Most of the photographs in the My World set, http://4pphotoblog.blogspot.com/2008/07/our-world.html, used either the 12mm, 20mm, or both extension tubes.
