HDR requires HDR software. There are ways you can mimic it in PS but true HDR needs the HDR program. HDR is really cool looking though. I had a program but I lost it when my last computer went down. I never really got the chance to play around with it.
And yeah, like TickleMyElmo said, when the lens is just a 60mm or 90mm or whatever, it is a prime lens which means it's a fixed focal length. Generally they are sharper lenses but they are also more expensive. I really like shooting primes but sometimes I like to have the ability to zoom. Right now I have 30mm, 50mm, and 90mm primes in my kit and one zoom that goes from 70-300mm. If I had the money though, I'd probably replace them with a couple nice zooms and keep the 50mm and 90mm Macro.
