I've searched on this but the search seems broken (or my search skill are) as the second topic in my search is "https://www.nikoncafe.com/vforums/showthread.php?t=182082&highlight=tamron+28-300", and it brought up "Share your best Macro-lens portrait shots" and not a hint of any discussion about this lens at all - bizarre! Hmmm... well I've got the chance to pick up a Tamron 28-300 VC. I like Tamron, I find they optically punch above their weight. However I'll be honest - I don't like all-in-one zooms, and putting one on a D700 seems a little like.. well putting square wheels on a Ferrari. Anyone tried it, and does the lower pixel density allow you to get away with murder on this sort of thing..?
