To my shock, I found the Helios-44-2 full frame adapted onto the APS-C FujiFilm X-T50 was... quite good for street photography? I'm used to much wider lens setups but... I am really happy with how this dreary, rainy winter Sydney day looks through Helios using the Nostalgic Neg film simulation - and what the punched-in lens let me do from a distance.
