Don't worry about all that liking stuff and get you a 105/2.5 while they are still cheap. Any one who owns a Nikon F mount camera digital or film DX or FX should own a 105/2.5. :)

Well I just like the 105/2.5. It is a legendary Nikkor lens known for portraits. They are cheap. You can get one for about a 100 bucks that will work with your camera. Don't worry about all that DX FX stuff right now. Someday in the next few years I think 105/2.5's are going to become expensive.

Now if you ask Sam he is going to tell you a 300mm...which is sublime. :)

The 50/1.8 short barrel is a neat one...

The 75-150 Series E is a beautiful performer. Cheap but not so in the future.

The 28/2.8 AIS is a masterpiece of modern lens manufacturing...they still make them new...the epitome of their wide angle skills....wide angle never was the domain of SLR's that was rangefinder stuff...SLR's ruled at the longer focal lengths...

Plain and simple? You can use any of them regardless the letters with your camera...just might have to do it in manual though which is easy once you get the hang of it. :)

Fx and dx refer to the sensor size in your camera.
Fx=full frame sensor (same size as a traditional 35mm film)
Dx=crop sensor (smaller sensor, used in your D5100)

As for lenses, anything labeled as AF-S will auto focus on a D5100. All other Nikon lenses will work in manual mode.

The numbers tell you how much of your subject you will fit in the frame.
50 is considered a baseline as it is basically the scene as it would appear without any lens. Anything under 50 that is considered a wide angle lens, whilst over that is a zoom lens. Some lenses have two numbers. This means the lens has a focal range between these numbers.
Note: because you have a Dx sensor on your camera, the numbers will need to be multiplied by 1.5 when working out your focal range. This means 35 is now your baseline.

I'm sure there are plenty more thorough explanations online you can find but this should be enough to get you started.
