Hello,does anyone use the Sigma 150-500 for spotting? I know some of you are using the Canon 100-400, and I have the Canon 70-200 F4 USM but it's not long enough to shoot at Boston,does anyone can give me the advice about Sigma 150-500,thanks~

Take a look at this thread I started a few months ago when I asked a similar question. It should give you some insight.....

I would add to that thread (I am doing it here since it is fresher) that the lens will NOT focus in extreme cold conditions (perhaps not so cold too) as two different friends with two different copies have experienced. Warming up the lens will return normal operation. This is confirmed via Google searches as well.
Now, as for quality images, I have seen some output from a 16MP Nikon D5100 and when the focus is good, the lens produces pretty good output!

When it's been attached to my D40x, I've never had a problem with it, even in cold weather.
Last weekend was the first time I had it attached to my new D90, and I was getting the infamous "Err" message. Once I shut the camera off then back on it would take care of the problem.
See my Flick stream for the JetBlue and Air China shots- those were taken with this lens.

Okay.........this sounds like a money making idea........you've heard of leg warmers, now what about lens warmers (you can even have one with a low leve heating element. This would be the high end version of the lens wamers.)). You can even have custom lens warmers for your type of camera (Canon, Nikon, Sony, etc.).
