I have a Steiner sunshade on mine...bought it from sport optics (great vendor, btw). I can double check and take a pic if you want. I know Chris posted a pic up there but for some reason I *think* mine has a more seamless fit. The only thing I notice is that it has a different finish than the kahles. Functionally it works great. I leave it on almost all the time because I feel like it protects the glass a little bit.
