Perhaps BIF but the lens can be used for many other purposes. That is what is meant and the TCs are great for many other uses.

To a lesser extent, the TC light loss also affects ISO noise ....

Just a note. I believe that the max f-stop for autofocus on your 7D is f5.6, so AF won't work when using the teleconverter, but will work without it.
That is correct for a 7D. If the OP has a 7D Mark II, than he would have AF with the center point only and a maximum aperture of f/8.

I recently purchased a new Canon 100-400 II telephoto lens, and it is by far, the best piece of glass that I've ever bought or used and that includes some old 35mm high end prime lenses. I know nothing about the Sigma line of lenses, but I shoot Canon and want Canon lenses. FWIW, I don't put Chevy parts in my Ford!
The Chevy parts would increase the value of your Ford.

If I had one! I drive a 1974 Yugo Delux.
Chevy parts will definitely improve that!

Can't take a chance on a defective Chevy part. Drive my Yugo 4.6 miles weekly and need a dependable vehicle.

Mine only needs one gear for that.

No it's a Jeep. I actually have two of them, one just wasn't enough.
Jeep=Just Empty Every Pocket.

As a Sigma 150-600mm Sports owner I agree the Sigma is a lot of lens for the price.
