Well, while both lenses mentioned are excellent lenses, the "bigger sister" (or brother, or sibling) to the A 35-105/3.5 is the A 28-135/4, and not the A 70-210/4.
While the two-touch 35-105 and one-touch (focus/zoom sleeve) 70-210 may make a good complementary pair for shooting, the 35-105's "genetic" relationship to the two-touch 28-135/4 (using the same sort of "pseudo-macro" mechanism as well) should be very easy to recognize.
EDIT: Take a look at the optical diagrams of these three lenses -
A 35-105/3.5 -
A 28-135/4 -
A 70-210/4 -
Furthermore, having owned both of the "big and lil' 2-touch siblings" for many years (as well as the A 70-210/4 for an even longer time), I would say that, if the 35-105 is a "stack of primes", the 28-135 is a "tower of primes", and was my favorite "wedding lens" for quite a few years back in "Ye Olde Film Days of Yore" [TM]. Of course, for those that find the 35-105 to be "very heavy" (I don't), the 28-135/4 will seem "OMG heavy" - LOL.
The optical diagrams above, BTW, are from Boz's excellent K-mount site -
