I went to a spot in our village frequented by some sunbirds to try out the Sigma using a tripod, but loosely for support only, and with OS "ON" to see how well it could Autofocus and capture images: Camera: Canon EOS 50D Exposure: 0.002 sec (1/640); Aperture: f/9.0; Focal Length: 439 mm ISO Speed: 1000 Exposure Bias: 0 EV Flash: Off, Did not fire Note: The lens was not fully extended and was shot at 439 mm; ISO was set at "Auto" using Aperture Priority.    All images were cropped for composition. Some sharpening and very little de-noising was applied. For a Non-L lens valued at almost half the 100-400mm L IS Canon lens, what do you think? |

Nice shots, Bobby.... I didn't know that you have the 150-500 OS!
From the photos I've seen taken with the Bigmos (150-500 OS), sharpness seems to be fine and the OS works well for hand holding. I prefer the rendition of the OOF BG by the original Bigma (50-500) though, that of the Bigmos seems too dreamy for my taste.

I got it just last Friday. I had read reviews that Sigma tweaked it and that the newer versions were much improved. At Php 45,500.00 it is a good value for money lens alright, but it's still a bit on the heavy side for me. Aspiring bird photogs can cut their teeth with this lens and then move on to the more expensive L-glass later, if they are so inclined. I am still in the market for a 500mm glass that doesn't need iron man to carry. I was seriously thinking about the 300 2.8 from Canon or Sigma (to match with a TC), but when I tried Osawa's glass (a Canon), it almost broke my wrist! :-)

I think if you want the lightest birding lens with IS and AF at 500-600 mm, the only choice is the Canon 300 2.8 IS + 2x TC. Sylvia and Tonji just got one.

Hehehe, that Canon lens is very heavy at 2.9 Kilos and quite expensive. The main reason I got the Sigma was that it weighs "only" 1.91 Kilos - and still my arthritic left hand can't handle it too long. :-)
