There are only about a zillion different Viv 28's, all reputedly pretty good. Although I must admit I don't use my Viv-Tokina 28/2.8 in T2-M42 mount, because it's a booger to stop-down the aperture except on an M42 auto camera. So I'll probably sell that one. A Viv-Kiron 28/2.5 just arrived today, and a big heavy sucker it is too, much more massive than a Tamron 28/2.5 that arrived a couple days ago. A couple other Viv 28's should arrive Real Soon Now and I'll be able to stage a proper shootout. Anyway, someone around here has a database of known Viv 28's and I'm sure it'll be mentioned in this thread soon.
At least a couple of Viv 24's exist. I have a Viv-Kiron 24/2 that's reputed to be a real gem but mine is damaged and I don't know when it'll be fixed (spare parts are hard to find, says the repair tech). Be aware that the lensmakers Vivitar contracted with also supplied lenses to other marketers under many names, such as Sears, Soligor, Lentar, Albinar, Focal, Makinon, Porst, et al. My Tokina-made 21/3.8 can be found under several of those names, and a Viv-badged version is on eBay right now for well under US$100.
Also be aware that 24mm and 28mm lenses see the world quite differently. Down in that focal-length neighborhood, 3-4mm change the field-of-view considerably. A 21mm is MUCH wider than a 24mm, which is NOTABLY wider than a 28mm. I find myself using a Soligor 24/2.8 more than any 28mm, but that's just me.
