My experience -
The 35-70 2.8 AF is an all-metal little thing, was a top line lens back in the day and very capable (introduced around the time of the 8008 I believe) - but seriously prone to veiling flare. Nice macro capabilities but I eventually dumped mine due to the flare.
The 28-70 2.8 is a massive beast of a lens but insanely good. You "just stick with a prime lens" guys have obviously never owned one. These days my living comes from 4K video, corporate stuff, and that's on my camera 90% of the time, but it rocks on my film cameras (and man, it's glorious for video on a super-35/ APS-C sensor). It's an "S" lens with a notorious-for-failing focus motor, but buying one with a dead motor is like stealing if you don't rely on AF. Yeah, it's huge, but it's such a nice piece of glass. Looks just tits even wide open.
For a killer deal on a long tele, the 80-200 2.8 push-pull is a cool lens. Big and heavy, but easy to shoot handheld. At 2.8 the contrast and sharpness drops a hair, but it's actually a very pretty look, very flattering for people, kind of has a "glow" to it. F4ish it really tightens up. They can be found for three hundred bucks or so. Very little money for a whole lotta mojo. You can get more modern variants (zoom ring and tripod mount) either 80-200 or 70-200 for much more cash, but on a budget, it's really a badass lens. Lots of metal, even beaters can perform fine.
The 300 F4 AF is also a little monster of a lens; the 180 2.8 AF is also very impressive. Both were from the film era and should do fine on most bodies.
