Modified Bubble Lens ASAHI PENTAX Super-Takumar 1:1.8 55mm M42 Mount ☆ This lens has been modified to create bubble bokeh with emphasized outlines when shooting with a blurred background, instead of the usual round bokeh. It's perfect for shooting Christmas illuminations and other scenes this season. * The focus plane when shooting bokeh tends to be soft focus (slightly out of focus, or close to not being in focus). ★ Beautiful ring ghosts, characteristic of Super-Takumar, also appear. They occur even in bubble bokeh, so you can capture bubble bokeh + ghost effects if the conditions are right. ☆ Appearance: Few scratches, scuffs, and paint loss; a near-excellent condition. ☆ Lens (dust/debris = small, mold = none, haze = small, scratches = almost none) - all within a range that does not affect photography. Yellowing of the rear element is also minimal. ★ The mount is a screw-in M42 mount. ☆ Focus and aperture operation are good. ☆ Accessories (all used): ・Front PENTAX metal cap ・Rear generic cap ☆ This is a bubble bokeh-emphasizing lens with a modified lens configuration. ☆ No special operation or settings are required; it can be handled in the same way as a normal 55mm lens. You can also enjoy various expressions by adjusting the focus and aperture. ☆ "Close focus, wide open aperture" - This setting provides the most prominent round bokeh effect. ☆ "Distant focus, wide open aperture" - Creates swirling bokeh. ☆ "～Higher aperture value" - The soft focus effect diminishes, resulting in a more normal depiction (the bokeh effect is reduced when stopped down). ☆ "Close focus, mid-range aperture" - Creates hexagonal bokeh. ☆ The focus range is approximately 40cm to infinity (there may be slight individual variations) (distance scale may be off). ☆ As it is an M42 mount, a separate mount adapter is required for use with modern digital cameras. ☆ Sample photos include those taken with SMC/Super/Super-Multi-Coated TAKUMAR, but the effect is almost the same.
