Looking for a good, slightly longer, macro prime that is relatively affordable and fairly compact. Just doing some web searches, the Tamron 90mm f2.5 looks like a pretty good option. Is there anything else I should be looking for? FL range would be in the 80-100mm region. Not too interested in 50mm macros. Using it on a GX7. UPDATE: Thanks for all the replies, but I pulled a 180 and ordered a Oly 60mm macro instead of going the manual route.
