The Sigma USB Dock for Pentax K Lenses

The Sigma USB Dock for Pentax K mount allows you to update / adjust compatible Sigma Global Vision lenses using their free software. Key features include:

* Pentax K mount

* Limited compatibility

* Customized calibration

* Free software required

Pentax K Mount. We carry this product in multiple mounts with this one being the Pentax K-mount version.

Limited Compatibility. The USB Dock is only compatible with Sigma’s Global Vision line of lenses listed in the recommended section on the left-hand side of this page.

Customized Calibration. With four adjustable categories to customize focus distance for prime lenses and sixteen for zoom lenses (4 distances x 4 focal lengths), the USB Dock allows precision calibration for the specific camera / lens setup. Additionally, when used with certain lenses you can also customize three different AF speed modes, three Optical Stabilizer modes, and constrain focus distances within a specific range.

Sigma Optimization Pro. The free Sigma Optimization Pro software is simple to use, enabling you to update firmware as well as make focus adjustments on the latest Sigma Global Vision lenses.

Are we out of stock?

If you don't see exactly what you're looking for and that makes you sad, please give us a shout. We might have good news for you. Here's a link to our contact form.

We offer a 3-day inspection period on all sales, during which time you may return the item for a refund of the purchase price, not including shipping.

On this item, we include a LensAuthority 90-day limited warranty. This warranty covers damage that arises from normal use of the item. It does NOT cover accidental or intentional damage. More details are available in our FAQ section.

In addition to the standard 90-day warranty, you may have the option to purchase an extended warranty. If we're able to offer an extended warranty on this item, you'll see a checkbox to add that warranty - see the area just above the "Add to Cart" button.

If you select the extended warranty, you'll get additional protection from Consumer Priority Service ("CPS"). The CPS warranty will take effect after our 90-day warranty ends. However, the CPS warranty term would begin on the date of purchase. For example, if you buy an item with a 2-year extended warranty today, your coverage would end two years from today.
