80 to 85mm was the choice of "portaitist" in the world of 35mm cam. That makes it about 55mm on APS-C sized sensors. It doesn't mean the job can't be done with longer or shorter focal lenght. Whatever lens work for you is the lens to use. But a 50 to 55mm lens is a very good starting point to experiment, and, like the O.P. asked, it won't break the bank and give very good results.
I'll agree part of the way here. Because of the crop factor, a 55mm lens on an APS-C sized sensor has the equivalent field of view of an 80-85mm lens on 35mm film/FF sensor. That doesn't mean they're equivalent in all other aspects, like compression/expansion, depth of field etc, that give a particular focal length a particular "look".
Originally posted by Rene` Thank you all for your feedback. I really do appreciate it. I am amazed at how much there is to learn.
I still don't understand how people are supposed to know the difference between "prime" --- good --- and crap.
When discussing photographic/cinematographic lenses, "prime" just means fixed focal length. That is, not a zoom.
As for good and crap, if the photographer does everything right, and doesn't expect the equipment to break the laws of physics (which a lot of photo industry marketing seems to indicate the equipment can do), then a "good" lens will result in a pleasing image with no significant optical flaws, and a "crap" lens won't.
Maybe.
But if your particular photographic vision leans toward early 20th century pictorialism, the last thing you'd probably want to shoot with would be a 31 Limited, a lens that many claim is one of the best, if not the best lens Pentax has ever made. There's no perfect lens. Just different tools for different jobs. And luckily, truly abysmal lenses are pretty hard to find. New lenses, barring manufacturing defects, are pretty uniformly good, and a lot of lousy old lenses have likely made it to a landfill rather than the used department of your local camera shop, eBay or Craigslist.
