In June of 2016 Mike G had the chance to make a visit to Tanzania with family and friends where he spent several days testing the Sigma 150-600 C lens in three different Tanzanian National Parks – Tarangire, Ngorongoro, & Lake Manyara.
Bottom line – Mike G, who has used the Tamron 150-600 VC lens and Canon L series big glass on African safaris in the past, was very pleased with the lens and feels it is every bit the lens the Tamron is with possibly better stabilization and color reproduction and offers a better bang for your buck than the much more expensive Canon or Nikon options.
All of the following images were taken with a Canon 5D Mark III and the Sigma 150-600 C lens.

The first thing most people are going to notice with this lens is the price tag – much less than the Canon 100-400 II, Nikon 80-400 VR, Canon 200-400 w/ 1.4x, or any of the prime BIG glass lenses either Canon or Nikon offer. And, you are gonna save size vs a few of the other options while not adding much bulk vs some of the slightly smaller options – Canon 100-400 II or even Nikon 80-400 VR.
High quality glass is vital to the optical quality of any image. The quality Mike G observed in this test shows that the 150-600 C is an excellent lens with high quality workmanship coming out of the Sigma Aizuwakamatsu (where Mike actually lived for several months while a young man) factory in Japan. The FLD & SLD glass elements help the lens achieve a high degree of clearer, sharper, greater clarity and excellent contrast across the focal range. While not weather-sealed like its Big Brother the S version the lens should withstand most light weather situations but you’ll want some form of heavy weather protection should you venture out in heavy rain/snow.
Mike G finds the lens be very sharp at all focal lengths up till about 550mm – especially when stopped down to f/8. Above 550mm stopping down to f/11 helps keep the center of images sharp and clean.
The next thing you are going to notice is a wonderful range (150-600mm) which will allow you to fix this lens on your favorite camera body and shoot all day without changing lenses – which can be extremely convenient and save a lot of sensor cleaning while out on safari – or even shooting birds in the backyard or wildlife in Yellowstone National park. With a minimum focusing distance of 110.2″ critters will have to be pretty close – 9.2′ or just a tad over 3 yards away to not focus. If you are that close to any wildlife you had better be near small wildlife that cannot hurt you or in vehicle that can help protect you. For sporting events – depending on the event – it can be the lens that reaches out and touches the action.
Some of you may ask – what about the min/max aperture range of the lens – f/5-6.3 – f/22 and capturing images in low light? Not a concern if you are shooting with a relatively new body that handles noise/high ISO situations well. Feel free to bump that ISO up to keep your shutter speed up if needed. Plus, the Sigma Optical Stabilization, which includes an accelerometer for better panning results, is going to get gain you anywhere from 2 – 3 stops when handholding with good, solid technique. So, go ahead and shoot away.
How about the auto focus performance you may ask? Mike G found it to be very accurate, fast, and quiet. The Sigma Hyper Sonic Motor is reliable and Mike G found it be a bit faster than the Tamron 150-600. The lens does also come with a focus limiter switch which can be handy when subjects are more than 33+ feet away.
Do we (Mike G) recommend this lens? Yes. This lens offers great image quality at an excellent price point. The outstanding performance seen coupled with the savings makes this lens a viable option for even the most serious wildlife photographers.
