Canon EF 50 mm STM + Canon 70d - no focus on infinity

[netty_pl]

Hi everyone!

I've purchased lastly objective mentioned in the title. I cannot get sharp picture on infinity focus. When I'm trying to look at distant object AF simply does not give a conformation on focus and I cannot take the picture. But also on MF I cannot get focus? Everything works fine on distances from ~ 1 ft up to about 15-20 ft, just the infinity is a problem. 

?

Has anyone same problems with EF 50 mm 1.8 STM objective? Is there any solution?

Sounds like a defective lens. If the camera can focus properly with other lenses, then the 50mm is most likely faulty.
