Lensbaby Burnside 35mm F2.8
supersize


Description:

This lens produces a special "swirly" bokeh. To achieve this effect the lens has too diaphragms, a primary 6 blade diaphragm controlled with the aperture ring, and a second 8 blade diaphragm controlled with a slider.

The primary diaphragm controls exposure and the amount of swirly out of focus in the image, with larger apertures producing the smallest in-focus area and most swirl and smaller apertures producing a larger in-focus area with minimal swirl.

The secondary diaphragm is used to control the amount of vignetting as well as the quality of the bokeh in the out-of-focus areas of the image. When wide open, the swirl quality will be softer and when closed down, there will be greater detail in the swirl and more vignetting will be apparent.

The aperture ring has no "A" setting and the diaphragms are fully manual. This means that only manual exposure (with metering at the set aperture) or Av exposure automation is available.

I wasn't expecting too much of this lens (LBA got the better of me) and I had experience with a Helios 44 (as well as other Lensbaby products) before which were not hopeful but this lens surpassed my expectations. This is not your typical plasticky Lensbaby 'toy" with a gadgety feel and photographic result you can only hope to use once in every 10000 shots. I could very well see me take this lens out for street- or nature-shooting and leave it on the body the whole day.

The center of the image has a very large sweet spot of very good sharpness which increases as you stop down. At the wide end, if the gods are in a good mood, the lovely swirly bokeh jumps out at you. Getting the swirl to show up is a bit of hit and miss (and I suppose a bit longer experience with the lens) but when it does, it's unmistakable and lovely.

Overall, the lens renders an almost 3D-like image (as long as you're good with having edges and corners contribute to that feel by being soft) where the central subject really stands out. Can't say much about colour rendering as I shoot raw generally and manipulate it to my own liking anyway. The lens is decently resistant to flare, possibly because of the second aperture iris up front. As one can close the secondary iris and create some intentional vignetting, I found it very nice to avoid clouds totally going to white on landscape pictures.









[EDIT]Two added examples after some careful thinking. The first seems to be the optimum result to be had with this lens on APS-C, the second is a bit dizzying to my taste.
