–Did some more 50mm lens comparisons. Tricky business: Helios e.g. is shockingly sharp wide open in the middle of the field, but gets really fuzzy as you head out toward the periphery. The Contax 50/1.4 wasn’t quite as good as its reputation would suggest. The Rikenon 55/1.2 was quite outstanding. The Pancolar was the weakest of the group, and the Summicron (like the Contax) seemed a little weaker than I would have hoped.
–Walked to UPS to pick up an MBK front flipper. Nice knife.
–Tried to replace the battery in the iPhone SE 2020. Broke the cable connecting the display. Crap. Spent a long time looking at Red iPhones on eBay; ended up getting an SE 2022. The 13 Mini is smaller with better specs, but it lacks the front button and has an ugly lens set on the back. Besides, the SE was $206 (compared to $600) and the seller was honest about how the battery capacity would have degraded to 83%-86% over the years. I’ll try it, and replace the battery (carefully) if it seems to need it.
