I'm seriously considering this as my next lense. Does anyone have one? If so, how do you like it? Also, I know it focuses internally, but does the front of the lense extend out when zooming, or does it remain fixed?

thanks in advance for the info

Scroll down and it'll show you how much the lens extends when zoomed.

Ahhh thanks. A good resource. I'm still a little hesitant about getting this lense. Not sure if I should spend a bit more and go for the 170-500.

I cannot comment on either of those lenses from personal experience, but I do own the Sigma 50-500 and the Sigma 17-70. Both are built excellent. The 50-500 is part of the EX line. Its built like a tank. I haven't gotten to totally explore this lens to find all its potentials and faults. From what I have used it for, it has performed very well with super fast focusing on both of my Canon bodies.

On another note, the 170-500 takes 86mm filters, same as the Bigma 50-500. I own 1 86mm filter. Check the prices on quality 86mm filters and you'll see why. LOL

I have the Sigma 100-300 F4 and the 50-150 f2.8

They are both wonderful pieces of glass, but both are from the EX line -- Sigma's top-end. They are built like tanks. Another advantage of these is that you can use the EX series teleconverters with them (which I don't believe you can do with the 135-400). I found my 100-300 on ebay in mint condition for a bit over $500.
