I took this Pentax X90, since I knew and was happy with the brand. I has a Pentax 35 MX since 1980 with optical ranging from 35 to 210 and macro rings. He always works very well. Take a bridge I was a little disoriented on handling, but I made it. Surprising the result of my first macros, the depth of field is greater than the rings of the MX. But I seriously gaining speed, the insect does not have time to fly away I made the photo. When my old accessories, tripod, lacrosse, accordion arm. No problem, the pitch of the screw X90 is identical to the standard SLR. One downside it is not possible to use a cable release and connect a second ambient flash. For this four stars. When the Amazon service, then there YES! Five star.
