I ordered myself a Lensbaby (2.0 version), last week, as well as the macro attachments. It arrived just the other day, and yesterday I ventured out to give it a try with some mixed results…
A few good shots out of about 80 total. I had most fun playing with the macro attachment, but even normal scenes give good results. The principle is simple: you’ve got a flexible lens mount, so as you bend it and compress it, you’re changing the focal length and therefore adjusting the plane of focus as well as the “sweet spot.” It took me a while to get the hang of focusing, especially on the shaky macro shots and moving subjects (pesky insects!). Want a different aperture (thus expanding or contracting your area of focus), just pop out a disc and put a new one in.
Even though the lens is about as manual as you can get, my Canon continued light-metering in Aperture Priority (Av) mode, and adjusted the shutter speed accordingly. This is pretty nice, since it takes one extra piece of guesswork out of the process. Of course I still found myself making plenty of adjustments.
I’ll keep playing and continue to post the successes in my lensbaby set on Flickr.
