[QUOTE="Blade Canyon, post: 380296, member: 15302"] [ATTACH=CONFIG]124372._xfImport[/ATTACH] The auto-focus on my AF-S Nikkor 28-70 2.8 (precursor to the modern 24-70) went kaput during a class last week. Nikon estimates $600 to repair the lens. I bought it for $800 in the last year... Ugh. Final decision: buy a new Tamron 24-70 2.8 with VR (VC) to replace it. That done, I decided to disassemble this $800 paperweight, just in case there might be some obvious and very easy thing to fix. Not so. After seeing the gizzards on this baby, I have a whole new appreciation for the engineers and the cost of these AF zoom lenses. It might be reasonably efficient to mass-produce these on an assembly line, but to take the whole thing apart to fix the auto-focus or even get rid of dust or fungus... that's easily a $600 job. Now I have this cool Terminator-looking hunk of glass on my shelf to remind me the lens game changed when AF came out. Just take an old manual lens and build in a computer better than anything the Apollo program had. [/QUOTE]
