Very nice pcitures.
Question: I am in need of 300mm f2.8 IS and since money is an issue, I have been looking at the Sigma 120-300mm f2.8. I get some what confused when I see that people mention how good 120-300mm f2.8 (and comparable to 300mm f2.8 IS) is and then read that Sigma 100-300mm f4 is sharper than the 120-300mm f2.8. I have seen how good canon prime is. So I were to give 10 to canon prime (for picture quality and AF) what would you give to Sigma 120-300mm f2.8 for picture quality and AF? What about Sigma 300mm f2.8?
2 of my friends bought 120-300mm f2.8 but weren't happy with the outcome even after sending it to sigma for calibration and ended up buying canon prime. So I am looking forward to people's opinions who own this lens.
Ok, I am going to start this with my thoughts and why I have both of these lenses. I need the zoom more for baseball, hockey, and Volleyball where I can't move around as much and the zoom is very very handy, and the added reach of the 300 2.8 zoom is a big plus in poor lighting.
The sigma 300 prime IMO is a better lens! period. I really enjoyed shooting with it, and my keeper rate was much higher. In my hands the Sigma 300 f2.8 acted more like the Canon 300 f2.8 then the zoom did! With the zoom the images were not as sharp, and the AF was not as fast and accurate. The zoom is not bad! but not as good as the prime. The Sigma prime 300 is as close to the Canon as you can get, it was fun shooting with this lens knowing I was getting the shot, and not worried about if I got the shot or not. "I hate that feeling" The prime is also a lot easier to hand hold, it is shorter than the zoom and weighs less than the 120-300 and Canon 300, when I first opened the box to take this lens out, I was surprised at how small it was. With the lens hood on I have it attached to my 40D with BG, and it fits in my LowPro Nature trekker II bag.
If you give the Canon a 10, then I would give the Sigma at least a 9 The canon IMO is a tad, and I mean a tad sharper, the AF may be slightly faster but I did not have the canon in hand to compare and from what I remember, it was too close to call. The Canon was also a little more contrasty, but this is an easy fix in PP. Even when I had the Canon I never used the IS, so it is a non issue with me.
I would give the Sigma 120-300 a 7. Again, I am not saying the zoom is bad, but I have to put more into the images to get theme to where the prime is, and they are still not equal. The 120-300 images were not as sharp, required even more contrast, and color. The AF speed of the zoom was close to the prime, but not equal, but when you needed to track a subject the prime was noticabley better. and also when using a 1.4X tc, the zoom boken is not as pleasing where the prime is still silky smooth, and without the TC on the Prime is still a tad better.
Hope this helps.
Paul.
