I have the 49 mm version of the Tamron - had it for decades and it's
great with one exception, as mentioned in this thread of a few months
ago:
http://pdml.net/pipermail/pdml_pdml.net/2012-March/308059.html
As Darren pointed out, the 'centre spot' problem is a known issue,
which (thankfully) only manifests itself under certain lighting
conditions. I had been using the lens for over 20 years without ever
noticing the problem previously (or since).
I've just found the AF version of the lens at a good price which
should arrive in a day or two. Unlike the manual focus version, the AF
version goes to 1:1. I'm looking forward to trying it out.
