Re: Good M42 lenses that are sharp(or not soft) wide open

From my experience Russian Helios (I do have 44M-4) is sharp in center stop down to 3.5, for sharp edges you must go to 8-11. (I've made a film how it looks like - Helios 44M-4 I do have also Takumar 55 / F1.8. Fully open is soft in center, but just stop down to 2.0 makes a big improvement. On 5.6 this is pretty sharp lens.
