Quoting Dr E D F Williams: > Is the 105 mm f2.8 EX an autofocus or a manual lens - and the others?
They are all autofocus. The Macro lens (105mm) has the usual (?) clutch mechanism on the lens for switching from AF to MF. IMHO, it has a nice feel to it in the MF mode (I guess you'd say that it's "well dampened", or something like that...) For more info the lenses (filter size, min focusing distance, etc) you can check out this lens chart on Sigma's website: http://www.sigmaphoto.com/html/lenschart.htm oR! you can just ask me more questions. oh.. by the way, i also have a Tenba camera bag (backpack) on eBay right now if anyone is interested... http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2911884826 Thanks again, j.
