Last month I purchased the Lensbaby Twist 60 Optic.
It is based on the Petzval design and is supposed to produce a swirl of bokeh, much like the older Helios lenses. I had been curious about it since it was released but also very hesitant as most of the uses seemed to be focused around portraiture photography. As I rarely shoot pictures of people, I wondered how this style of lens effect would work with inanimate objects also.
At wide open f2.5 & f2.8 the swirl effect of the Twist 60 optic is very pronounced.
It does mild down significantly by f4 – f5.6 and is almost non existent by f8 producing a normal view from any standard lens. I found the wide open swirl effect to be a little distracting but really do like how a minute amount of swirl from the f4 – f5.6 range does make the subject stand out a bit more.
Where this optic really shines for me is mounted on a 25mm extension tube, bringing it up to almost a 1:2.4 magnification macro.
I did try it on a 44mm tube but didn’t like the effect as much as the 1:2 ratio.
Though I occasionally find a use for the Sweet Spot or Slice Focus of my other Lensbaby optics, my favorite optics so far have been the Zoneplate and Plastic. I’m quickly seeing the Lensbaby Twist 60 optic will join those two.
Something about the “so called” imperfections of early film photography appeals to me.
