Pt. 2 of 3: Be My Lens, Baby...again
Remember our fun with the Sima? The Lensbaby Composer (and all the Lensbaby line, since they use interchangeable elements) is 50mm in focal length compared with the Sima's 100mm. That gets into the usable range for many landscape opportunities, and makes a decent average focal length for portraits and details. Need wider? They can do that... it's that system concept I love so much. Offered as additional accessories are a 0.6x Wide Angle lens adapter and a 1.6x Telephoto lens adapter (in a set). That makes the 50mm equate to a 30mm or a 80mm lens via the front-threaded lenses. Yep, there is a macro kit as well, which would be really handy for those of us who shoot close details of things.
Instead of being happy with f/2, f/4 and f/5.6 with the Sima lens, we can now get down to f/22. Why would you want to shoot a "soft focus" image at f/22? Well, what the Sima didn't do was skew the plane of focus... the Lensbaby skews the "sweet spot" of focus to the point you choose. Want the whole left side of the image to go completely out of focus? We can do that.
When the folks at Lensbaby shipped me the demo unit, I was very excited to open the box and find (first) a Lensbaby Composer (yes!) and a thoughtfully included set of lens elements. The Composer shipped with the double glass element in it, with the f/4 aperture. That seemed like a good starting point, so for the first several hundred shots I did with it, I left this configuration in place.
As I first handled the Composer, I was satisfied with the obvious build quality... it isn't heavy, but feels solid. It is made of metal and composite materials, with a metal lens mount. The lens has a locking collar at the rear - if you want to lock the lens in position, simply turn the locking collar to lock it in place... since the lens doesn't move easily on its own, I would think that most people would use the locking ring when on a tripod. Inside the lens optic, there is a magnetic arrangement that holds the f/stop apertures in place. With a little practice it is easy to drop the f/stop aperture in to the front of the lens, but if you have trouble, you can always use the handy magnetic tool provided for the task.
As previously noted, the Composer does away with the hard but flexible rubber bellows of the Lensbaby and Lensbaby 2.0. A composite ball-and-socket allows the front of the lens to move independently of the rear, creating changes in the plane of focus that the lens throws. This shifting of the plane of focus is what gives the Lensbaby its signature look.
