Has anyone had experience using this lens with a Nikon D5100?

It does a very good job, obviously in manual focus mode, but I am sure you already knew that.

I just discovered that the lens I'm being offered is a Canon FD mount. Wold this work on my D5100 with an adapter?

If it's a mechanical adapter, it would work OK...Bear in mind though that the model camera you are mounting it on will not meter with older manual focus lenses, adapter to make them fit or not. You will have a very limited focus range with the adapter (you will be lucky if you can focus out to 6 foot max). I used to shoot manual focus lenses on on Nikon D70s (also did not have metering with manual focus lenses) I tried adapters for other OEM lenses & quickly saw the extreme limitations & stopped (my adapters were M42 thread mount adapters)... Metering using a non -metering DSLR camera/lens combo involves "guessing" the settings & then using the LCD/Histogram to fine tune the exposure. You can start by estimating the exposure using the old "Sunny 16" rule that we used in film days when cameras had no meters. Oh, best subjects are ones that are fairly static & situations where there is no rapidly changing light levels. That Vivitar lens is a sharp macro, shame it's in Canon FD mount though. That mount died when Canon went to AF cameras & changed it to the EOS mount. You can find any number of good manual focus macro lenses on the used market for decent prices, you just have to work a bit harder to get the images. Many of my older macro images on my Flickr stream were taken with a Nikon D70s & an older 105mm macro lens. I got around exposure problems by using a ring light..
