LittleWolf said:$50 is definitely a ripoff. The "C" brand is known for milking its customers this way, not sure about the "N" brand. Most third party lenses come with hoods, and some lenses (in particular mid-range tele lenses), even in the low-cost segment, used to have slideable hoods built-in.
If you have a lens whose front element is already deeply recessed, an additional lens hood won't gain that much. Also, fixed hoods for zoom lenses are problematic - unless the lens uses additional mechanics to adjust the hood, they may cause vignetting at the wide end or may be not very effective at the tele end.
If you have the choice of spending $50 for a lens hood or a "UV filter for protection", there's little doubt that the hood is by far the better investment for image quality.
yup, 3rd party provides lens hood.
if u r wondering about "N", yeah they do
