>>3387731I would highly suggest looking into 35mm primes or wider, or going for a collapsible 50mm. The 50/1.4 that
>>3387785 shows is a really good 50 but the problem with 50s is that you can’t put them in your pocket very easily while on the camera. If you like carrying constantly then this is an issue. A 50mm 3.5 Industar 22 solves this issue. I can confirm that collapsing it won’t hurt the shutter or light baffles, since I use one. I hear the 50mm f/2 Leica collapsibles don’t work, but I have no experience.
Look into wider Canon LTM lenses even if you’re a 50mm guy. 50mm on rangefinder is kinda pushing it since ya hard to nail focus especially with how dim a Canon P’s rangefinder is — I have great eyes and it’s still the dimmest rangefinder patch I’ve ever seen. With a wide lens this is less an issue, and 35mm is a good choice because it’s wider (hence less issue with focusing since it matters that much less), significantly smaller, easier to zone focus, and pretty fast — you can even get a Canon 35mm f/1.5 if you have a $1000 laying around. I use a 35mm 1.8 because it’s small, virtually same quality as the 35mm f/2, matches the camera aesthetic more than any other Canon LTM lens, and fast enough for indoors. Only issues it has are already shared between LTM lenses (close focus of about 1m, 180 degree focus pull — though I don’t mind this second con since it makes for better fine adjustments).
Other suggestions are the canon 35mm f/2.8 which is essentially a pancake lens; a canon 25mm f/3.5, which is literally a pancake lens since it sticks out maybe 5-10mm max from the lens mount; any of the canon 28mm lenses which are ultra compact, but need an external viewfinder (unless you don’t wear glasses, cuz then you can just use the whole viewfinder beyond the 35mm framelines.) for a smaller fifty the 50mm 1.8 Canon is smaller but not much shorter than the 50 1.4 so the pocketable benefit isn’t there.
All up to how u shoot
