>>4324386You can adjust it by not putting the shittiest M39 Soviet lens on a fuckin Leica M body. Bro Jupiter glass is cheap at least put a J8 or a J12 on that mf. Ball out and put the J3 50/1.5 on it. I paid 200 bucks for my 1.5 Red "P"
Industars are technically 28.8mm flange distance but the problem is they only register correctly on FED bodies, if you put them on anything else, that body has to be calibrated to it to register correctly in the rangefinder. My FED-4 has a Lanthanum 61 L/Z on it and it made awesome pictures, very sharp and very colorful, but it's calibrated to that lens. All my Jupiter lenses,plus my Orion 28mm register correctly on my Canon 7, even my 135 after some finessing.
The Industar isn't necessarily a bad lens and it will make sharp pictures especially the 61 L/Z Lanthanum model found on the FED-4, but FFS put a decent lens on that Leica or I'm gonna kick you in the dick. Nigga is putting a 20 dollar lens on a 1500 dollar body, meanwhile I'm over here with my 700 dollar Russar 20/56 pic related on a 30 dollar Zorki lulz
