The only problem with the PKA tamron mount is that it seems it doesn't take into account (or not well) for chaging aperture lens eg zooms.
In the manual of the adapter they something like (from memory) that when using zoom with changing aperture being f/4 or less (not sure about f/4) there *may* be exposure errors. Thought you should know. BTW, on my Tamron SP 70-210 f/3.5-4 it lets me select f/3.5 at 210mm which shouldn't be of course (on a Z1, ist-D) as it should be written f/4 and nothing brighter. Also, this mount doesn't NOT have aperture vales written on it which is annoying if you wanna use the lens also on a camera like MX,KX,LX which display aperture value in the viewfinder with a mirror system. -- Thibault Massart aka Thibouille ---------------------- *ist-D,Z1,SuperA,KX,MX, P30t and KR-10x ;) ... -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
