But the auto-focus motor is in the lens, and it does not use up the camera batteries. Come on, now, you can not have it both ways, if it is good enough for Canon (grin)...

It actually tested quite well in Modern Photo back when it came out (early 1980's) along with the ME-F. I think it's a decent enough fast zoom (comparable to Tokina's AT-X 35-70/2.8), but is a nuisance to use as a manual focus lens - not only is there a "useless" (for manual focus) big blob (battery box, etc.) hanging on the bottom of the lens barrel, but the focus ring is worse than on the F 50/2.8 Macro. It is (in my opinion) only worth having for a historical match for a collectible ME-F (and I do have two of 'em for that reason, one each for my chrome ME-F and my black ME-F). It's fun to use in (primitive) autofocus mode on a ME-f once in a while, but I don't think that it has much use otherwise (in my humble opinion).
