3rd party lens hood compared to original, is much cheaper. As long as u got the correct hood for the lens, it doesn't matter original or 3rd party. For me, hood is more for protection. If u got the wrong one, u can try go back the shop for an exchange.
i have absolutely no issues with 3rd party hoods on my lenses. :dunno:
Totally agree, if you bought the wrong original hood you would get the same problem, nothing to do with 3rd party or not.
