During the week of July 19th, Gentec International, the Canadian distributor for Sigma lenses, kindly loaned me the Sigma 150-600mm F5-6.3 DG OS HSM Sports Telephoto Zoom for review. The first thing I noticed about this lens upon arrival was the impressive, professional build quality; all metal construction, sturdy metal lens hood, silky smooth rotating tripod collar with click stops, and a beautifully smooth zooming action. This lens weighs in at 6.3 lbs, roughly 5 lbs lighter than a Nikon 600mm prime lens – a light-weight when compared to a hefty prime lens and at a fraction of the purchase price too. Another noteworthy point is that this lens’ minimum focusing distance is a mere 8.5 feet compared to Nikon’s 600mm prime lens which has a minimum focusing distance of 15.7 feet. This will allow this lens to very functional in creating imagery of smaller subjects such as Chipmunks, Chickadees, and Frogs. When reviewing lenses I do not pay attention to lens charts and such or other on-line reviews of the product. I prefer to take the lens out into the real world and judge its performance capabilities based on my preferred locations, subjects, and shooting style.
When designing this new Global Vision lens Sigma clearly had professional use in mind. The lens is weather sealed to protect it from dusty environments and it is splash proof as well. In addition, the front and rear elements of the lens have been treated with a new oil and water repellent coating. This lens is sure to withstand the demands of the professional photographer.
Another noteworthy point; the Sigma 150-600mm F5-6.3 DG OS HSM Sports Telephoto Zoom is compatible with the optional Sigma USB Dock and Sigma software allowing the user to apply custom settings and autofocus calibration settings. I did not use the Sigma USB Dock to set any custom settings prior to conducting this review.
In the photos below you can see the zoom lock switch conveniently located just behind the zoom ring which locks the lens at 150mm and all other controls are nicely arranged vertically on the side of the lens barrel. First is the Focus switch, followed by the AF distance limiter switch, Optical Stabilizer switch, and lastly the Custom settings switch. For the purposes of my review I used the autofocus position, the AF distance limiter switch in Full, Optical Stabilizer in Position 1 (for static subjects – Position 2 is for panning action), and the Custom switch OFF as I did not program any custom settings. Each of the photographers accompanying this review were either handheld or tripod mounted. This will be noted in the image captions for each photo.
IN THE FIELD PERFORMANCE & IMAGE QUALITY
To review the Sigma 150-600mm F5-6.3 DG OS HSM Sports Telephoto Zoom was mounted on my Nikon D800. I was excited to try this combination due to the selectable sensor crop features of the Nikon D800. As a result I would often switch between the FX (full frame) sensor and the DX 1.5 crop sensor. The latter is like having a built-in teleconverter at your disposal, ready and waiting. When using this lens with the DX 1.5 sensor crop activated the lens has a 35mm equivalency of 225mm to 900mm (folks using DSLRs with APS-C size sensors will particularly enjoy this long reach). This extended reach proved to be most beneficial in capturing flighty subjects such as Great Blue Herons, Beavers, and for close-ups of Bullfrogs too. At the lens’ minimum focusing distance of 8.5 feet and an effective 35mm focal length of 900mm this lens was quite deadly for Bullfrogs :) Be sure to read the captions for each of the images below as I have indicated which sensor crop was selected to create each image.
To zoom the lens in and out the zoom ring is turned in the same direction as Canon zoom lenses – the opposite direction to Nikon zooms. This took some getting used to on my part but by the end of the week the correct zooming direction had become second nature. My chosen location to put this lens through its paces was the wetland on Horseshoe Lake near Parry Sound, Ontario, in the Muskoka District and a short excursion down the Seguin Trail in Parry Sound. I used the lens both handheld and tripod mounted with the latter mode utilizing a loosened ballhead for additional support with the Optical Stabilizer (position1) activated. Once again do note the captions for each image for greater description on capture information.
NOT JUST FOR WILDLIFE
The Sigma 150-600mm F5-6.3 DG OS HSM Sports Telephoto Zoom is not just a lens for wildlife it is also a serious performer for landscapes too. I often utilize longer focal lengths to extract intimate scenes from the grand vistas before me. When doing so the lens was tripod mounted with the Optical Stabilizer turned off and the ballhead controls firmly locked. The mirror lock feature on the Nikon D800 was also utilized to eliminate any vibrations resulting from mirror-slap from degrading image sharpness. For landscape use I would highly recommend the use of a polarizing filter – this lens would require a 105mm filter size.
BACK AT THE COMPUTER
After a week-long shooting spree with the Sigma 150-600mm F5-6.3 DG OS HSM Sports Telephoto Zoom I arrived home to upload several thousand images to the computer. As I began editing and optimizing these image files I did note that aside from chromatic aberration being very well controlled, the resulting image quality surpassed my expectations with excellent fine details present. Any images that were not sharp was the result of me pushing the Optical Stabilization passed its limits. It is important to push new gear to its limits to know what you can accomplish in the field. Know your gear and know its limits.
If you are ready for the extended reach of a 600mm lens the http://www.sigmacanada.ca/product/sigma-sport-150-600mm-f5-6-3-dg-os-hsm-lens–sos1506dgs/ is highly recommended – professional quality images, in a weather sealed design, at an affordable price. The 150mm to 600mm zoom range is very versatile, allowing for tight portraits as well as scenes that take in the surrounding environment too, without the need to change lenses. This saves time that in-turn may yield more results when the action heats up. The light weight design yet solid build makes this lens a joy to handhold when photographing birds in flight or when working from a canoe, as I did, which is something folks that already own heavy weight prime lenses may be interested in if they are looking for a lighter alternative. The Sigma 150-600mm F5-6.3 DG OS HSM Sports Telephoto Zoom is my new favorite lens and be my go to lens for all of my long lens work. The Sigma 150-600mm F5-6.3 DG OS HSM Sports Telephoto Zoom surpassed my expectations!!!
