>>3214578>Until the 90s, film was always a son of a bitch to use; of course you needed SLRs. Digital cameras, however, are reliable and easy to use. Why would you need gorillions of different lenses to get the right digital photo?This question suggests that either you're trolling or that you're a super duper beginner at photography. Since I remember asking very similar things when I first started out over a decade ago, I'll take it at face value and assume you're not a troll.
First, different lenses do different things. Telephoto lenses give you a different perspective from normal lenses and from wide lenses and from ultrawide lenses. A fast prime lens that's good in low light won't have the versatility of a normal zoom lens. Special effect lenses like tilt/shifts or petzvals or lensbabies give you entirely different looks than you can get from other lenses. There's no way to make one lens that will cover all of the bases for you if you're a serious photographer. So that answers the "why do you need gorillions of different lenses to get the right digital photo" question.
Second, the fact that you think "being able to use different lenses" is the only reason for using a digital SLR indicates that you don't understand the other big difference between DSLRs and digital point & shoot cameras (and cellphones, etc). I.e., digital SLRs have a muuuuch bigger sensor. Pic related--most compact digital cameras are down at the 1/2.3" size (or 1/2.5"). Cellphones are more like 1/3.2". DSLRs are up at the APS-C or 35mm full frame size. The larger sensor gives you much better low light performance, lets you use focus creatively, gives you more dynamic range, and really just generally gives you much better pictures. Plus, it lets you get close to the same field of view with the old film lenses that you got on film.
