Lets make a list. 50mm & larger.
Forgot to measure my T50 clone when I cleaned the systems, but from sheer looks I'd say it's rather 80mm or so...
i might have to get a set of those at some point. are they available in the US?
The XB1000 are exclusive to japan as of right now they had short run in sony style stores in the us but amazon dose ship them to the us still
