This is the swirling bokeh lens that's currently trending on Instagram and other platforms. Art Photo Group Exclusive Edition This is a Helios 44-2 f2/58 M42 lens, released by Russia's Art Photo Group with a limited serial number. It's highly sought after by enthusiasts. I had only seen it in online articles, so I never thought I'd be able to get one. Moreover, it's unused and has been serviced, so there are no operational issues. The lens surfaces are clean. In test shots, it produced clear images without any problems. There is no mold, haze, or balsam separation. The included lens cap is also carefully crafted. The lustrous paint that makes polishing it so enjoyable is simply irresistible. Includes a metal hood, UV protection filter, and original cap. There are no oil stains on the aperture blades; they are in a clean condition. It's said to be a masterpiece that rivals the original Biotar in terms of its sharp central image, and most famously, its swirling bokeh at wide apertures. It's a renowned lens that allows you to enjoy the characteristic look of old lenses, including vignetting. It's an f2.0 58mm lens. I took test shots with this lens, and they turned out beautifully with a three-dimensional feel. Shipping is free via Sagawa Express.
