Just wondering, im a complete n00b at lense and what the numbers mean. Ive seen some pictures of people shooting with the 50mm f/1.8 and was wondering if it will get some nice shots on shooting something about 20-30ft away or is this lense mainly for close up shots? I know its good for low lighting areas and its pretty fast. How will it look, im mainly into taking pics of people (family), my car in nice areas and some nice close up's and i dont plan on spending a ton of $$$ for a lense even though i know ill get some nice pics. thanks for the help!!
