More on the focus speed/accuracy

So I was playing around with the Minolta 100-300 and the Sony 55-300 comparing focus speed. To my surprise, when focusing from near to far or far to near, the Minolta was a little quicker.

The SAM motor in the 55-300 is accurate and quick as long as you do not lose focus and the lens then focuses all the way in or out and back. The Minolta is slightly quicker in that regard (not by much but it is quicker - accuracy may be a little better on the Sony 55-300).

Here is a video of the Minolta 100-300 focusing:

Here is a video of the Sony 55-300 focusing:

Here is a video of the Sony 18-135 focusing:


At this point, the 55-300 is a great lens for the price and is comparable to the Minolta 100-300 so far, but more of a sideways move than an upgrade.
