Excerpt: The canon lens hoods are all great in my opinion. This one is no exception. It protects and shades the lens well. The felt on the inside really cuts down on reflections and the hood fits snug on the lens. I always buy Canon hoods so I can't speak for the alternatives but I figure why risk a poorly fitting hood for $10-20 savings.
Excerpt: Some aftermarket parts works. Others do not. Lens hoods are the one item I buy factory made. When I wanted to purchase hoods for all my lenses, I bought one aftermarket hood to see how it would perform. I mean, a hood is a hood, right? Uh no. The aftermarket hood I purchased came in this weird two-piece design, the front edge of the hood appeared in some of the photographs, it was designed to be screwed on to the lens/filter threads instead of the hood threads which...
Excerpt: You need this lens hood. Here's why. The inner barrel of the 50mm f/1.4 extends out the front of the lens and moves fore and aft during focusing. It never fully retracts.

And it needs the hood to protect it from bumps when in use.
Excerpt: Not much to say about this. It's a well-made, over-price plastic ring that fits nicely on the lens and blocks out unwanted light. It provides extra protection for the front lens element. It can be reverse mounted for compact storage. The inside is lined with black felt to further dampen indirect light.<br /><br />Using this lens hood helps give photos more pop, more contrast. The effect is most noticeable on a sunny day but can also be seen indoors.
