I currently own a Canon EOS DIGITAL REBEL XS with just a Canon EF-S 18-55mm f/3.5-5.6 IS. It was given as a gift and I don't know much about cameras.
I'm looking to buy a lens for doing more zoom shots (mostly nature and wildlife), would the a Canon 75-300mm EF Zoom lens be enough? Not looking to spend crazy money as photography is just more of a weekend/hiking hobby. Do I need a lens hood?
Any other recommendations of lens or things I should pick up would be great!
The 75-300 is not one of Canon's best lenses.
I suggest either the EF-S 55 - 250 (slightly less reach, but much more portable)
or the EF 70-300 II.
You can often get a good deal on Canon's refurbished site:
"...would the a Canon 75-300mm EF Zoom lens be enough?"
Yes, it is to a very lot of people in your same situation. Perhaps a better choice would be the EF-S 55-250mm f/4-5.6 IS STM Lens. It is a much better lens but that is your choice.
