Have you tried your 55-300mm lens to see what results you can get?
It's not that this lens won't work for you. It absolutely will. A prime lens (one without a zoom) might work better. Probably will. But that 55-300 is going to do just fine to get you started.
Photoscan recommends that you set it at either 55mm or 300mm. I'm going to go out on a limb and say that you will probably want to set it at 55mm, unless you're photographing ants or something like that.
What is way, way more important than the lens that you are using is (amongst other things):
1. Good, in-focus shots.
2. Even lighting, no shadows.
3. Good coverage on your shots, meaning enough angles of the object that you're shooting to give Photoscan something to work with.
So, my recommendation is don't spend any money! Use the lens you have on the camera you have. It will give you great results if your procedure is good and you know what you're doing. Don't get hung up on the equipment you're using.
One last thing: don't shoot flat, untextured objects like bars of ivory soap. And don't shoot reflective objects. Neither will give you good results. Photoscan likes good textured, non-reflective objects.
Good luck.
