Thank you all for your help. Moving forward I purchased a Pentax K3 DLSR <http://us.ricoh-imaging.com/dslr/K-3_> and a Pentax 35 mm HD Macro lens <http://www.pentaxforums.com/lensreviews/hd-pentax-da-35mm-f2.8-limited-macro.html> (extremely low distortion rating). My picking some enthusiast brains on the Pentax Forums one individual (after I announced the equipment I just purchases) stated <http://www.pentaxforums.com/forums/6-pentax-dslr-discussion/294312-camera-recommendation-geometric-morphometrics.html#post3327944> that it is recommended to use 100-200mm+ lenses and zoom in to the subject to remain near orthogonal as possible. In hindsight I'm a little worried about parallax distortion (something that is supposed to be addressed by telecentric lenses which don't really seem feasible for my applications and definitely not for my budget). So for those of you that are more knowledgeable about this type of photography did I shoot myself in the foot? Should I try to return the prime 35 mm macro and instead purchase a 50 mm or 100 mm (meaning I'll need to be like 10 ft away from my 7-20 cm subjects in a two story room with a step ladder, lol).
