OK it seems a little quiet on here, so here I go with my first topic!



I've noticed in some lens tests the issue of residual spherical aberrations (focus shifts when stopping down). However I've never seen it mentioned in a Pentax lens review/test, is this something that the Pentax lenses are free from, or is it just the case that the issue was not mentioned?



Regards,



John
