Weighing up two options. Sigma 150-600 Sport (where I also have to buy new filters for the larger thread) versus Canon 100-400 USM II with existing 1.4 III Extender. Any thoughts?
Canon lenses seem to do well with the extender, no filter size change vs a bit more magnification. How often do you need a really long lens?
Sigma f6.3 and 6lbs VS Canon f8 and 3.8lbs. The BIG question is - Do you an f8 enabled AF body ??
The Sigma is f6.3 @400mm the Canon is f5.6 @400mm.
The Sigma is 6.3 at 600mm the Canon is f8 at 560mm .....
The Sigma has the potential for overall better field performance with the proper adjustments of the USB dock and physical management of the extra weight.

If you will be on bus tours you'll find yourself shooting out of the open window, no tripod. If animals like bears are involved guides won't let you walk or get anywhere near them. If you are taking private guided excursions, then your choice of gear would be different, but something like an 18-300 zoom meets most needs.If you are backpacking into the wild, the long lens may be useful, but then you have to carry it, and a good tripod too. Do carry your own supply of DEET bug repellant, as it sells out during mosquito season.
I have had both...I actually sold the Sigma 150-600 (due to its weight) and purchased the 100-400mm II with 1.4x III extender. I use it with the 7D Mark II. I like the combo and I know a few other Hoggers who use the same and have had good luck with it for birding/wildlife. Good luck!
Makes sense, I was going to take my 70-200 with the 1.4 extender but it does not give me very much extra with a full frame sensor. My only concern is the autofucus with the extender. My dealer says it will not go beyond F8 with the 100-400 and an extender but the Canon site says it will autofocus using single point. The cost of the filters with the Sigma is quite an extra, by the time I have added a UV and a Polariser it racks the cost up quite a bit whereas I can stay with the 77mm on the Canon.

The Sigma Sport goes to F6 at 305mm through 410mm, it falls to F6.3 at 410mm on out to 600mm.

Yes it is, thought you might like the actual numbers is all.
Quite honestly I gave up on extenders. Never really could get sharp images. I can go up to 300mm native. I'll stick with that.

The new 100-400 is designed to work with the 1.4 and you have to work to see loss of image quality.
I love my 100-400 MII and use the 2x MIII on it lots. It is a very sharp lens.

As always a lot depends on what you are going to do. Here are two links to using the Sigma sport with a 1.4X TC:
http://www.uglyhedgehog.com/t-301940-1.htmlhttp://www.uglyhedgehog.com/t-296454-1.htmlThis gives you an 840mm lens, but do you need that? The Sigma is much heavier making it hard to hand hold for any length of time. That is its only disadvantage. If you are NOT going to do a lot of hand holding that is the way I would go. The extra reach you can get might be a big advantage.

why do you need new filters. There is no reason to put filters in front of your lens for protection they just degrade image quality?
If you are choosing the lens for wildlife or sports with good light you are going to want the Sigma. If you aren't strong enough to handle it then you want the other lens.
The Sigma is well balanced, but a lot of people are bothered by the weight. Personally I think it's fine.
