Hikking the Pico do Lopo with some friends

These photos are from the same day as those I took with the Olympus 35 SP, but with the SLR I inherited from my grandfather. Even though this Sigma is worth next to nothing nowadays, my dad remembers it being really expensive when he bought it back in the 1990s. Last year, when I found it in the closet together with the OM-10, it was in terrible condition: the soft-touch coating had turned sticky, it was full of fungus, and one of the cemented doublets had started to separate—basically it was junk. After a few months, I managed to get a donor lens from Japan to replace the damaged doublet. During the reassembly, however, I didn't realize I had made a mistake: the lens wasn't quite reaching infinity focus (although it was very close). So when I tried photographing these landscapes, everything looked completely out of focus. That's when the circle of confusion came to the rescue. Even though the hyperfocal point was technically beyond infinity, stopping the lens down to f/8 brought infinity into acceptable focus. Honestly, looking at the photo, I wouldn't have guessed that the lens wasn't actually focusing at true infinity. As soon as I got home, I disassembled the focusing helicoid again and adjusted the assembly properly so the lens would reach true infinity focus.
