IR Hotspot Test Konica ƒ1.4 50 vs 57mm

So I tested my two Konica ƒ14 standards. 

50mm ƒ1.4 -- one of the worst hot spot issues I have seen. All the way open to ƒ4 before it went away.

57mm ƒ1.4 -- fantastic with no not spot at any aperture.

If you are buying a standard I Konica the 50mm is overall a better lens in terms of sharpness. So if you are only shooting normal and no IR it would be my choice, though the bokeh of the 57mm is better. If your primary interest is IR then the 57mm is the obvious choice.

Awesome post. Most IR hotspot lists don't cover old lenses. Have you tried the Konice 40mm f/1.8? That works really well in IR too.
