the 50mm 1.8 also had a 52mm thread so no reason it shouldn't work, but why would you want such a large hood on a small lens?
The hood is designed for full frame, right?
It's a 50mm hood on a 40x1.6 FOV 35 equiv....you might get some vignetting.
Wait, I think I got that backwards... You're using a shorter designed hood on a longer (equiv) lens. It should be fine.
But yeah, I concur, I wouldn't bother with a hood. I normally use them for protection, and if it,s threaded to the shifting barrel, I'd worry that knocks to the hood will budge the lens mechanism.
