Instax 500AF

I decided to buy an Instax 500AF, which are very hard to find (I only found 2 on eBay). "What's the difference between the Instax 200/Instax 210 and the Instax 500AF?" I here you ask.
Firstly, the 500AF has an auto-focus, unlike the 200/210 which have two fixed focal ranges: 0.6m - 3m and 3m - infinity. This gives a much sharper image as you actually have control on what the camera is focusing on.
Secondly, you can bypass the flash. The 200/210 only bypasses the flash when there's enough light. So you can't get and nice natural/low light images. Unlike the 500AF which gives nice images like the one below.
