ASAHI PENTAX Super-Takumar 55mm f1.8 (Late Model) M42 screw mount. Released in 1965. This is the popular Super-Takumar 55mm f1.8 on Instagram. The Super-Takumar, when used with backlighting, can cause light to spill into the background, allowing for fantastical photography. The prominent flaring is especially well-known, and taking photos into the sunset with backlighting can create a world that envelops everything. The bokeh is somewhat bubble-shaped, with emphasized outlines. This is a lens I highly recommend for those new to old lenses. Speaking of Super-Takumar, there's yellowing. Most lenses on the market have their rear lens group yellowed over time due to the use of atomic lenses, which drastically changes the color, making them unusable for film cameras, though digital cameras can compensate. However, this lens is offered with a focus on rare, colorless and transparent lenses. I have prepared some sample photos taken with this lens. I took night snaps in Shibuya with a K-3 monochrome. Monochrome photography can be difficult to focus, but the f1.8 aperture makes it easier to grasp the focus, providing a sense of security. When it comes to monochrome, the softness of old lenses leads to rich gradations, allowing you to enjoy a sharp depiction that modern lenses don't offer. The depiction is very good. This lens is a "defective" item! There is no mold or haze, and the optics are clean without yellowing. The operation related to shooting is perfectly fine, but there is a significant impact mark on the tip of the lens. I managed to remove the nameplate and disassemble and service it, but I don't think attaching a filter will be easy. Other than that, it's good, but the used market values appearance, and even with such excellent image quality, the valuation can't be high... For those who understand. For those interested in what a colorless and transparent Takumar is like. This is an affordable price for a serviced item, so please consider it. Condition: Defective, but no yellowing, good depiction! Appearance: Impact on the filter ring, please check the photos. Optics: Colorless and transparent, clean without mold or haze. Operation: Confirmed with actual shooting on Pentax K-3 monochrome. Accessories: Front and rear caps. Stored in a dehumidified storage. 4548 #AsahiOptical #PENTAX #Pentax #SuperTakumar #Supertakumar #MasterpieceLens #PeculiarLens
