yeah they are, but they'll last you a long time. you'll end up spending the same for 4 mediocre lenses that you would for one amazing one. and they aren't all super expensive. i mainly use the sigma 35mm 1.4 and it goes for around 600

Speaking of f-numbers, is there anyway to know which f-stop to use relative to the depth of field? Or is it just experience?

e.g. if you're trying to take a group photo, you don't want a low f-number. I don't know what f-stop to use... I'd guess f/4.5, take a pic, and see if everyone's in focus; if not, stop down a few numbers to f/6.3 etc.
