Summary: ok i was really wanting to start shoot macro. i was looking at all the macro lenses. i had bought the extension tude to use on my 50mm prime len. tubs did a good job but not what i was looking to get out of macro.so i narrowed it down to three lens, 1. canon 100mm F2.8L macro lens 2 canon mp-e 65mm lens 3 this 150 mm APO EX DG OS macro lens. i have a friend that has the 100 mm lens so i know what kind of image it would shoot.
Summary: This is an absolutely beautiful lens. When coupled with a Sigma 2x converter the magnification is amazing. You will need to use manual focus and tripod, but the pictures are really outstanding. Highly recommended for those of you who do not mind doing things by hand (manual). A good software program like Adobe Light room 5.6 will do the trick quit nicely in dressing things up a bit. I would now love to get my hands on the Sigma 180mm macro.
Summary: I rented this lens from lensrental before I bought on Amazon. I have a Canon 5D Mark iii with only a Canon 85mm f1.2 lens. The Sigma 150 has nice boket (not quite as great as my Canon 85mm). Might be slightly heavier than the 85 mm but the ring around it makes it easier to hold. You can get very close with the Sigma 150 (I have to be 30 inches away with the 85mm) which has NO macro and no Image Stabilization. The Sigma has two Image (called OS) stabilitzation settings.
Summary: Excellent lens, I usually using it for macro very sharp when use tripod or subject not moving, I happy with it and make great macro , It's fine lens to me sometime I using tele-converter with it like x1.4 or x2.0 I get large and sharp macro I use it with Nikon D7100
Summary: I purchased this lens elsewhere, and used. The used factor made no difference in quality, but it did cost half of what is advertised here. I have been a hobbyist and did not have a prime lens to shoot barrel racing, but did use a Nikkor 18-200 DX on a Nikon D200 in the past. That lens is fine when outdoors, but you need a better lens for indoor arenas.
