Photodo MTF graphs

Photodo MTF graphs

2005-04-29 by Paul Roark

I was checking for some lens test information and noticed that I'm no longer
able to get the http://www.photodo.com/nav/prodindex.html MTF curves.  Any
idea as to what has happened to them or if they are available elsewhere?
Those and the (other?) Swedish tests are about the most reliable I've even
found, even if they seem to have stopped updating them long ago.

Scott,

All I get is a little red "X" where the graph is supposed to be. 

Maybe my e-mail provider is blocking it.

See if you get the graph when you go to the Canon 50 EF f2.5 Macro.  If so,
could you e-mail it to me? :)

Thanks.

After further tesing I think it's just a bad link. I tried three broswers and got the x for the 
MTF graph.

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
