This is a BIG Vivitar long manual-focus telephoto zoom, which was probably aimed at press photography, ornithology, etc. It's fairly heavy and seems to be all-metal construction, and is an old trombone-style twist to focus, push and pull to zoom, design. It offers 1.5x macro on 35mm, probably closer to 1x on DX bodies.[attachment=11384:Vivitar_100-500_001.JPG][attachment=11385:Vivitar_100-500_002.JPG]
