I am totally hooked on using this new offering from the Sigma corp. I am also becoming very biased toward the lenses in general, this company is producing and this latest one added to my collection is no exception. I have featured a few photo’s taken with this lens on this blog when I first purchased the Lens, but now after having visited the Shetland Islands and having put it through its paces, I just absolutely love what this lens can do and the quality of the results. The Sigma 150-600mm f/5-6.3 DG OS HSM Sports is a versatile 4x telephoto zoom lens for full-frame DSLR cameras, and APS-C sensor cameras with an effective increase in focal length. The Sigma 150-600mm f/5-6.3 DG OS HSM Sports features a rounded 9 blade diaphragm which creates an attractive blur to the out of focus areas of the image,  It has built-in optical image stabilisation with an accelerometer for improved vertical and horizontal panning, an Hyper Sonic Motor for fast and quiet autofocusing, a zoom lock switch that can be locked at any focal length, manual override (MO) which is activated by rotating the focus ring while using autofocus, water and oil-repellent coating on the front and rear lenses, and dust and splash-proof construction. My good friend Ewen Bell has a real way with words and he also recently purchased the same Lens to use on our workshops in Scotland. So, read his take on what this Lens is capable of and his feelings about its quality and the conclusion he came to.

the first few images posted here show the ability of the lens and what the results are, all hand held, some on a rocking boat and in the most trying circumstances. It’s a beautiful piece of equipment indeed! The final few images I took of Ewen using the Lens on our workshops in both the Scottish Highlands and on the Shetland Islands.
