Why Stock Photos?
The short answer is that we use stock photos on some listings to save us time and to save you money. The longer answer is that we love to take photos of each and every lens, camera, and accessory, but doing so takes a lot of time and makes it difficult to get everything listed. So, we decided to compromise: take gorgeous photos of some things and charge a little more for them, and use stock photos for other items and charge a little less for those, all else equal.
The items listed here were tested thoroughly by our trained technicians. If they observed any significant flaws, you’ll see them detailed above. If the items listed here are exceptionally awesome, you’ll see that noted above too. Regardless, please remember this is a used item and it’s bound to have at least a microscopic imperfection.
If you're interested in purchasing an item with specific photos and ratings, we don’t blame you one bit. Please visit one of our Exposed! listings (if available), usually marked with a green badge. If none are currently available, by all means, contact us.

The Sigma 50-500mm f/4.5-6.3 DG HSM APO OS for Nikon
The successor to the long-lived and legendary Bigma, the updated Sigma APO 50-500mm f/4.5-6.3 DG OS HSM provides the widest zoom range of any supertelephoto lens we stock (or know of).The OS (Optical Stabilizer) function offers the use of shutter speeds approximately four stops slower than would otherwise be possible, making this now a reasonable lens to shoot hand-held--if you’re fairly strong. It also focuses as close as 20" (at 200mm), allowing you to use it for pseudo-macro shots too. This lens incorporates HSM (Hyper Sonic Motor), ensuring quiet and high-speed AF as well as full-time manual focus capability.
After playing around with it for an afternoon, I’m totally impressed (obviously on limited data, but totally impressed nonetheless). It is as sharp as the original 50-500, which is sharp indeed. The OS is spectacular, and really does appear to be four stops worth. We took some nice 500mm images shot at 1/125 second. Autofocus speed is adequate to the task and accuracy has been good. My summary: well, once again Sigma has designed a spectacular lens, and while the price isn’t cheap, it's a good value for what you get.

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.
