WIth the Tamron 150-600mm and the new Sigma coming out, will Sigma continue producing the 500mm 4.5? I know it's a prime and has 2 stops in favor on the long end so it's apples to oranges. Anyone using the 500mm 4.5? With the 150-600mm you get IS, weather sealing, more reach and possibly the same amount of sharpness?

2 stops are lot for any lens and a whole lot on a super-tele. I've not had the lens but had the 500/4.5L and have heard the Sigma is very similar => stellar. My guess would be that Sigma will update the lens to f/4 and OS some day (and price).

Sorry, it is just less than 1 stop difference. f 4.5 is considered the half stop between 4 and 5.6 while 6.3 is one third after 5.6, thus it shoulf be 6/5 of a stop advantage.

NO! f4.5 is 1/3rd stop from f4 (f4>f4.5>f5>f5.6) so it's exactly 1 stop to f6.3
That's the difference....1 stop. Where'd you guys go to school

Stops aside, I would not use a lens at this FL without some sort of IS. But, I generally handhold my shots so that is speaking from my style of shooting.

Yes, sorry it's 1 stop. I'd still say the prime has a place. I do hope Sigma updates the 500mm lens and puts OS in it. It will be interesting to see how the new Sigma compares to the identical and well reviewed Tamron 150-600. The price difference is almost double (Sigma $2000 - Tamron $1070).
