Two mm wide means that this is a small spider. The hairs on it are minuscule. It is a fine test for the flash on the Sony Alpha a68.The flash was set to default and it worked reasonably well. I'll test the flash adjustments another day.
I have also got to say that I have shot this species hundreds of times. At the start all I got was an orange blob. With the Sony Alpha a58 connected to the Tamron 90 it looked a lot better. The a68 plus Tamron 90mm takes the shot to a new level.
