Sigma150-600mm 5-6.3 Contemporary DG OS HSM Lens for Canon

I'm loving this lens, I'm getting some shots I never thought I'd be able to get. Sigma's products are the real deal and worth the price they charge for them. If you're thinking of making an upgrade to a nice long focal length, you can't go wrong with this one. Pretty light for it's size too. I'm able to get super clear pictures from a long ways away, and although I'd love a wider aperture so i dont have to rely on ISO as much, I know that'd be impossible without shelling out a ton more money. I highly recommend this for people who are looking to get into some real deal wildlife photography but aren't willing to make the jump to a lens that costs as much as a car. Excellent for starting a career or really drilling into a hobby.

For a "cheap" telephoto lens, this Sigma really blew my expectations out of the water. It is relatively lightweight, maybe only weighing 7 lbs. when paired with my Canon Rebel T7 camera body, so it is great to carry, even on long hikes or birdwatching trips.The AF feature is fairly decent, getting a nice clear focus within the 100-400mm focal length, in my experience. Beyond 400mm, the focus is less accurate, but the option for manual override helps in those instances. The AF feature is also on the slow side, so getting yourself acquainted with the manual focus may be helpful for capturing flighty birds or other fast moving objects.The optical stabilization feature also works great, allowing for smooth viewing even in high movement shots. There are two options: full stabilization, or isolated horizontal/vertical stabilization for tripod viewing. Occasionally, there can be a slight jump or "jitteriness" in the stabilization, but this is typically minor and does not last long.Lastly, this lens seems to do well in a variety of lighting situations. Attached to this review are pictures taken by myself in everything from the beating summer sun to cloudy skies. The lens performed well in all situations! I find many of the limitations in picture quality may be stemming from me using an entry-level camera body, and aren't the lens itself.All-in-all, I strongly recommend this lens. It is well worth the money, and is probably one of the best values for a telephoto lens out there.

This lens is incredible for the price. I originally bought the 100-400mm Sigma, which I understand is pretty much the same as this lens other than size/reach, and that lens was really good, but I think this one is a bit sharper. The reason I upgraded was because I loved the 400mm reach and got addicted to it, and figured 600 was better than 400, right?? I will say that this is quite a bit bigger and heavier than the 100-400mm version (twice the weight). Your forearm WILL get tired of you handhold this for too long, but it’s bearable. The autofocus on this is a little slower than the 100-400mm, and it seems to hunt more - but it’s possible it’s because the extra reach compresses the scene more (that’s just a guess, I don’t know if that’s actually how it works). Costwise it’s not much more than the 100-400, so I would base your decision on whether you’re okay with the extra size and weight. I could fit the 100-400 in my camera bag just fine with the hood and camera attached, but I had to upgrade my bag for this. That said, the reach is AWESOME, coming from a 200mm. I’m using it on a Nikon D7500, giving an effective 900mm telephoto reach. The construction of the lens seems very high quality and solid. I couldn’t be happier. The one down side of this lens (and it is a big down side) is that it’s awful in low light. It’s completely fine in daylight, but in shade you’ll be using pretty high ISO to have even a chance at a good shot. On a cloudy day in the shade, you’ll have trouble even at high ISOs. Lastly, I tried this on my old Nikon D5000, which doesn’t do well at higher than 400 ISO, and it was unusable in anything other than bright daylight, so I might not buy this if you have an old camera. That said, if you want anything even close to this kind of reach in a faster lens, you’ll pay 10-20x the price of this, so take that for what it’s worth. There always trade offs. For the price this is an insanely great lens.

I am writing this review because I read other peoples reviews that helped me make the decision to get this. I am very impressed. I am not a professional photographer but this is perfect for the nature shots I was looking for. Most of my shots have been without a tripod and the ones that came out blurry were some of the shots of flying birds. With practice, I have been able to get great shots of flying birds thanks to the VR feature. I am often surprised at what else I captured in long distance shots that I did not see during the shot (fish in the ospreys claws as she flew). Yes it is a tad heavy but much more manageble than I expected. I could not afford the lenses in the thousands of dollars so this was a very acceptable price point to get the features I wanted.
