Q: 1. I have the lens dock ... loaded the Sigma software ... was able to check for firmware updates for the 3 Sigma lenses I have it works with/35 art/24/105 art/150-600 c. Thing is, unless I missed it, NOT ONE WORD in the instructions, or on the software on the PROCEDURE for fine tuning. Did I miss it? How is it done - step by step, anyone. Or where to find the PROCEDURE for fine tuning the autofocus.

A: The Sigma dock will allow you to update the firmware of a lense and to set auto-focus finetuning for multiple distances and, in the case of zooms, multiple focal lengths. The settings you enter are written to the lens, so it will have to be recalibrated if you use it on a different camera. The dock does not have a way to test the accuracy of your lens' auto-focus. For that, you need to buy something like the SpyderLensCal calibration tool or use a diy setup.

Q: 2. Is dock compatible with Sigma DG 120-400 HSM and Sigma EX 105DG HSM lenses for updates?

Q: 4. I have the Sigma 18-35mm art lens and a Nikon D5200, so just checking that this is the dock I would need to purchase for that setup. I almost ordered the USB Dock for Sigma Lenses by Sigma since it's a Sigma lens, but then saw this option, which I'm assuming would be correct if it's based on mounting the Sigma lens to a Nikon body. So, as I said, just wanted to be sure I'm ordering the correct dock for my setup. Thanks.

A: Yes, that is the correct dock. You do not want the one for Sigma lenses. You want the one for Nikon lenses.
