>>3629052>best general purpose lens focal length? 55mm?there isn't any. for any type of shooting exist preferable focal length. for me main focal length is 135mm it works just fine in street "athmosphere" shots.
if you're new just get ~30/~50mm prime for aps-c or ~50/~85 for full-frame
if you're leans more towards art photography go with "Medium telephoto" (you in america have really weird photoslang for russia it would be just "narrow angle" or "long focal" ) ~85-135mm lenses (on full-frame)
if you're into more report style (i dunno some insta blog or else) go with "standart lenses" (no, really that slang is does wierd) ~35-50mm (on full-frame)
if you want shoot facebook trips but with high quality get some good zoom
