I had the 35-70 kit zoom twice over - once on the SF1 my wife bought around 1990, and again on the SF10 I bought a few months later. She also bought the 70-210. When I rediscovered these two cameras a few years ago I wore out her SF1 and bought a couple of $25 replacements from KEH, along with 35/1.4, 50/1.4 and 100/2.8 primes. I'll often choose to take it with me over the F6 as it's as clever as I need and no cleverer, so not confusing (and I think the lenses are better than my Nikon lenses). I do use the AA battery grip as these batteries are cheap and available everywhere, unlike the 2CR5. Here's a quick portrait grabbed at work with the 35-70mm:
