This is not going to be a tech-heavy review of the Sigma 150-600mm Canon Sports lens. I am not a pixel-peeperc and the professional reviews available about this lens online are far superior to anything that I could write. Rather this is going to be a cumulative review (meaning I will update it periodically) in which I provide my hopefully useful firsthand experiences shooting with it. br brFirst let me sayc I originally didnt think I was going to purchase it. I thought that renting a 500mm Canon F4 would suffice in situations where Id be photographing birds and other long distance subjects. But when I thought about itc renting a prime like that for more than a week or so can be really expensive. And when you have an enormously expensive lens like a 500mm F4 or 600mm F4 on loanc you can never really relax (or at least I cant) because images of the lens smacking into the concrete haunt you. br brAlsoc the Sigma 150-600mm looked like it might be very useful for daytime sports events like those I sometimes photograph. I use a Sigma 120-300mm F2.8 for a lot of that but sometimesc I have felt myself yearning for more range. br br04-11-2015: Maiden voyage with the lens at the National Zoo in Washington DC br brMy initial impressions of the lens have been very favorable. The lens feels a lot more professional than the Sigma 50-500mm (aka Bigma) that I used to have. I hate using cliches but the all-metal (or is it almost all-metal body) comes across as built like a tank. br brWith that solid construction comes weight. The lens is not a light one to shoot with (carrying it in a backpack is fine). I was able to handhold it some at the Zoo (the day was nice and bright so I could ratchet up the shutter speed enough to do that without having to move the ISO up to ruinous levels. Neverthelessc I found myself tiring enough over two hours that I found it much easier to prop up the lens on the fences enclosing the animal exhibits. I am pretty certain that most people will want to use the lens with a monopod or tripod. Im definitely planning to use the lens with a tripod on my upcoming trip to Svalbard. br brIll let the images Ive included with this review speak for the sort of pictures the lens is capable of capturing (I used it with a Canon EOS 7D Mark II). I selected as the samples ones where the focal length was over 500mm. By and large I was pleased with what I captured. br brOne feature that I thought was pretty useful was a focus limitation switch that would allow you to specify the ranges at which the autofocus would work and when it would not. This helped ward off some of the hunting phenomenon. br brSo to wrap up this installment of my reviewc I am pleased with the lens and I look forward to my next outing with it. br brFor those who may wonderc I purchased this lens (at list price) from Roberts Cameras a couple of weeks ago. br brUpdate (photos from my trip to Svalbard in June 2015) br brJust a few thoughts ... I had a great time up in Svalbard (the Norwegian Arctic island complex). The Sigma 150-600mm played a key role in helping me do that by getting what I think are some pretty good shots of Polar Bears walking near my ship (but not really near). br brThis saidc the lens was a bit heavy lugging around on hikes on the coast...but not much worse I think than what it would be like lugging a Canon 500/600/800mm instead.
