It depends on the 210mm lens. There are a couple threads as to which 210 lenses cover. I use a Schneider APO Symmar (not the newer L type) and it covers, but barely. The newer L series will work and the Rodenstock APO Sironar S will work. Older Schneider Angulon and Super Angulons, and the newer Super Symmar XL will. Some people say G-Clarons will, but I don't know. If you have any of the type I listed you will be fine. Otherwise I couldn't say.

The 135mm lens will not cover. I do not know of any 135mm lens that will. If you want an extreme wide angle like that, I have heard, though not tried, a Schneider 120mm f/8 Super Angulon and a 120mm f/8 Nikkor-SW will barely cover 8x10. Do some research using the search function and you will get more complete answers.
