Summary: the main reason i bought this lens is i do a lot of hiking and carrying a 7 pound lens around instead of my 12 pound 600 makes a big diff. i am still learning how to use this lens, when to use stabilization and when not to. i have noticed the pictures are sharper.
This is a birders/wildlife photographers dream lens!
7 March 2012
Summary: I purchased this lens for birding and wildlife and to a lesser extent, compression of landscape scenes. I had a 400mm 5.6 but went for the 500mm f4 for the IS. I considered the similar 600mm f4 IS but it was just too heavy in comparison to the 500mm f4 IS. The image stabilization is outstanding.
Summary: This is an increadable lens. I bought it for wildlife and bird photography. It is a little heavy, but with some practice I got to where I could hand hold it to shoot birds in flight. I added a 1.4x teleconverter for a little extra reach. This was an upgrade from a 400mm f/5.6.
Summary: Este lente es lo máximo en calidad, precisión, precio/valor, puedes hacer zoom a una foto hasta el final sin perder calidad en lo absoluto. Es un dineral, pero lo vale dolar por dolar. Lo compre, los resultados son magnificos y estoy feliz con mi 500 de Canon.
Summary: I ordered this lens via Amazon from Calumet and it arrived ahead of schedule and was perfectly wrapped. I have not had a chance yet to shoot in the field but "tested" the lens in the backyard. Image quality is what I expected after having read a lot of reviews here and elsewhere.
Summary: If you have any thoughts on going into the field with the 500mm f4 without a tripod....I hope you're strong. You can get away with a couple of handheld shots, but it needs to be a bright sunny day ! The lens itself is extremely well built, and takes magnificent photos.
Summary: This lens, when mated with my MKIII is incredible, and when mated with my "quicky" digital Rebel, is amazing! It's ultra sharp, ultra quick. I shoot for several sports photography companies, and shoot for enjoyment for colleges that my children attend.
