most obvious difference between kiron 105 and tamron 90 is that kiron goes to 1:1 magnification on it's own while tamron goes 1:2 and needs matching tube and/or flat field converter to go 1:1 (or beyond if you use both converter and matching tube).

kiron comes in several iterations:
- Kiron 105mm f/2.8
- Lester A. Dine 105mm f/2.8 (Dental lens, often labeled with a dental focusing guide)
- Rikenon 105mm f/2.8
- Rolleinar 105mm f/2.8
- Vivitar 105mm f/2.5
- Vivitar 100mm f/2.8

I see great pics from both lenses.
From a practical point of view, the tamron is relatively common and typically about half the price of the kiron/vivitar 105mm, and there is no problem re mount being adaptall, you just need to get the right mount to go with. The 105mm is fixed mount and can be really difficult to find in the mount you want, particularly if you are looking for an advantageously priced auction.

In terms of weight, the Kiron is about 650g, the Tamron 420g.
