joseph_gledhill Posted May 6, 2009 Share Posted May 6, 2009 <p>Does anyone know what type of motor is in the new Tamron 90mm f/2.8 Macro? Is it a ring type or micro type motor and how does it compare to the Nikon AF-S 105mm in terms of noise and speed? Many thanks.</p> Link to comment Share on other sites More sharing options...

hiromu_kurosaki Posted May 7, 2009 Share Posted May 7, 2009 <p>It is SLOW. I have tamron on Canon and Nikon VR. Tamron is really slow, but for macro, there is no problem with slow focus... It is, however, a bit of problem when trying to shoot something else...</p> Link to comment Share on other sites More sharing options...
