Originally posted by chunkiness I have some old glass I started collecting to try on my DSLR. I purchased a Sigma Zoom Master Multi-coated 1:3.5 ~4.5 f=35~70mm, a Tokina SZ-X730 75~300mm F4.5~5.6 Macro 1:3.8, and an SMC Pentax-F 1:4-5.6 35-80mm.
'Old' does not necessarily mean good. I suspect you will find those old consumer zooms to perform rather poorly. Many of us (I know I did) started out surprised that you could buy these old lenses for little money. But we quickly learned that old and cheap is still old and cheap. Better to focus on one good quality lens rather than dozens of poor quality ones that you will just waste time on.
