Yes, the aperture do change when I change the focus. But the max. aperture never get bigger than 3.2. And the lens should be a 2.8 lens.

Also, I test my Sigma 150/2.8 micro. The max aperture do not change. So i guess it is either a Tokina thing or it is just a bad copy.

I will call tokina see what they say tomorrow

Make sure you are checking the lens maximum aperture when the lens is at infinity. At any other focus distance it may not be showing maximum.

In god we trust, all others are suspects
