I found that the OS worked really well, providing at least a 2.5 stop advantage, closer to 3 stops as average. Many of my nature shots were taken whilst handholding the lens and relying on the OS to neutralise camera shake when light levels were lower resulting in slower shutter speeds. The light weight (relatively) of this lens didn’t really push me towards using a monopod, although I did use one for some of the testing. I prefer using a monopod with the big lenses when covering sporting events or doing birding photography on foot. An information sheet which doubles as a user manual with all relevant info and warnings is also provided. In the sturdy cardboard box the buyer will find his lens with lens caps front and rear, lens hood, padded neoprene carry case and a lens strap. The plastic lens hood uses a bayonet type fitting and clicks securely into place. Size: Typical size for a lens of this class I didn’t find it to be a bulky lens. The lens will still feel a little hefty to those not used to the large tele-zoom lenses. It is almost a full kilogram lighter than the Sigma 150-600 S and just about a 100g lighter than the Tamron 150-600. Mass: Being the lightest in its class the lens is easy to handhold and does not feel such a dead weight when walking longer distances in the field carrying it by hand. The lens tightens securely in the collar with the familiar twist knob operation. Different settings can be stored in two memories, C1 and C2.Ī very sturdy, removable tripod mounting collar is supplied. Mode 2: Panning mode – OS in the vertical plane onlyĪlso fitted is a special Custom Selector Switch: using the USB Dock (sold separately, and which basically looks like a rear lens cap with electronic contacts and a USM cable) with the free Sigma Optimization Pro software the user can update the firmware of the lens and add custom settings to his lens setup for AF, OS function and focus range.Mode 1: Normal OS in both horizontal and vertical planes.Optical Stabiliser Switch: A two stage OS is included: An ultrasonic type focus motor that Sigma calls HSM (Hyper-Sonic Motor) for a fast and quiet AF function is standard for this lens.Ī focus limiter switch is fitted, providing settings of 2.8m – 10m, 10m – infinity, and the full focus range. How often this will be used remains to be seen, I didn’t find the need to use this feature, but as usual it’s nice to know it’s there if you need it. Zoom creep occurs when the lens is pointed down or up with the lock disengaged.įocus mode switch AF/MO/MF: Offers not only the standard auto focus (AF) and manual focus (MF) modes, but also MO which is Manual Override allowing the manual focus ring to be operated even when the focus is on continuous AF mode. The zoom ring operates smoothly with an anti-clockwise rotation to zoom from 150 to 600mm. As with the Sigma 150-600 S, I found this to be quite useful When set at these 100mm intervals it can however be disengaged (except for the 150 lock setting) with a slightly firmer twist of the knurled zoom ring. Also shown to the right of the switch panel is the tripod mounting ring with twist knob for tightening.Ī Zoom Lock is fitted which securely locks the lens at 150mm for transport purposes, and can also be set at full 100mm zoom settings to assist in accidentally slightly moving off the required zoom setting. On the right, top to bottom is the Focus Mode Switch AF/MO/MF, Focus Limiter Switch, Optical Stabiliser Switch, Custom Selector Switch. The Sigma 150-600 C and the Tamron 150-600 are very close in terms of mass and dimensions, with the Sigma 150-600 S being the heavier and bulkier of the three models. The specifications shown below are as provided by the manufacturers. Priced at around R14,000.00 at the time of writing this, it is about R10,000.00 less expensive than its more expensive sibling, the Sport version of this lens, and very closely matching the pricing of its main competitor from another third party manufacturer, Tamron.įor easier reading I will use the following nomenclature to refer to the lenses being discussed: Offering slower maximum apertures typically at f6.3, these lenses give the enthusiast the perfect alternative to expensive fast prime or super tele-zoom lenses. The very popular range of 150-600mm zoom lenses, taking over from the 150-500mm models, has received yet another boost with the Sigma 150-600 f5-6.3 DG OS HSM Contemporary entering into this market segment, catering for those who are on a tighter budget and cannot justify the expense for a 500mm or 600mm f4 prime lens, or even the Sigma 150-600 f5-6.3 DG OS HSM Sport version of this lens.
