Summary for Sigma 50-500mm f/4-6.3 EX DG HSM APO ...- Love the Bigma
Notes on Sigma 50-500mm f/4-6.3 EX DG HSM APO ...- This lens is about as versatile as they come with 50mm up close and 500mm to get you out there. It is not for the faint at heart. It is a full load to carry, but it takes great pictures. T-pod mounted this lens is tack sharp on detail.The HSM is fast and with no rotation on the front you can get those split second shots. While not prime glass it is all the bang for the buck.

Summary for Sigma 50-500mm f/4-6.3 EX DG HSM APO ...- it is great, but it is heavy
Notes on Sigma 50-500mm f/4-6.3 EX DG HSM APO ...- this lens is great for bringing in the long distant stuff.
i wouldn't suggest that you go on a 2 mile hike with this lens because it is very heavy. to use it correctly you should have a beafy tripod, although i used it with my cheap aluminum tripod. it is also slow, which means you have to have decent light to get great pictures. don't expect to take this lens into deep forests and get good photos. but if you give it a good light, like at a football game, you will get great results. the only reason i am selling mine is that i want to hike with my camera and lens. i now have a canon 70-300mm lens it is not any better in the light department, but is considerably less heavy.

Notes on Sigma 50-500mm f/4-6.3 EX DG HSM APO ...- If you are looking at a BIGMA, you are most likely price-conscience. Nothing wrong with that because this lens gives a lot for a little price. In good light, it provides a great pictures. Great ability to change to varying degrees of distance from the subject, making it very versatile. But without IS and good light, it lacks a bit. I love to shoot youth football, and day games are great, but night games are impossible. So if you want to shoot at night, get a Canon IS lens. If you are going to shoot different distances, especially outdoor sports, this is a great lens.

Notes on Sigma 50-500mm f/4-6.3 EX DG HSM APO ...- This is the lens that is on my camera (Cannon Rebel XTI) the most. It is very versatile. I am still a beginner, but a serious one, and the range it has is very useful. I shoot a lot of wildlife and it is great. It is very heavy so you need a sturdy tripod, although, you can hand-hold this camera, even at the 500 range, in good light and get great shots. One big problem with the lens is it gets a lot of dust on the inside on the internal lens. I have to go get it cleaned every now and then. I am too nervous to take it apart myself. I have had this lens one year and love it very much. It has even taken a couple of spills and still works great.

Notes on Sigma 50-500mm f/4-6.3 EX DG HSM APO ...- This lens needs a lot of light and I have not had an oppurtunity to shoot it with the ideal light. I want to give it a 4, but I need more time.. I dont think it will be a five... This is a big lens and I have not had much luck hand holding it.. You need a tripod or monopod for sure.. I found the images very soft, but I have seen more experiencef shooters get great photos with some help from photoshop... For the price you can't do much better... I found it useful at f8-f1l at an ISO of 400.. So there is some noise, which can be fixed in photoshop.. I will update this review once I get some light.. so take this with a grain of salt..
The bag it came with could have been a little longer so I dont have to take off the hood..
Keep in mind I am amateur... I am sure with time.. this will be my 3rd favorite lens in my bag...
