I am using this for a sigma 100-400. The lends fits perfectly width wise and has about an inch of room length wise. Overall the case is well made and looks good.

This is an excellent product. However, as the description reads it does not fit the 200-500mm Nikon lens. And is way to big for the 16-35 & the 70-300. I think it’s specific to the 70-200 2.8. There may be others it fits but..

This Lowepro Lens Case, 11 x 26mm, is a near perfect/custom fit for a Sigma 100-400mm f/5-6.3 DG OS HSM Contemporary Lens - including the lens hood when the hood is not mounted, but reversed & stored/slipped over the end of the lens. There is about 3cm of extra space between the interior of the case and lens; Good for an extra filter or two, plus lens cloth or other small items you may wish to carry.Quality materials & everywhere: thick & dense protective padding, solid zipper; clean & nice construction. The neck strap is quite adequate & fairly soft/smooth on the edges, so it won't feel as if it's cutting into your neck. The carrying strap on top of the case lid is convenient for quickly grabbing your lens. Nice to have a flat side to the case, so it won't roll around if you lay it on its side. Glad I bought it when I did; The price jumped about 25% in the last 2 months. (hate when that happens)
