I have some questions regarding flash set-ups and working distance. Specifically the MT-24EX vs. the MR-14EX or Sigma’s EM-140.
I previously shot quite a bit of “extreme” macro and used Sigma’s EM-140. However my working distance was never shorter than 1.5”. The EM-140 protrudes about 1” from the front of the lens (I assume that’s the case with MR-14EX as well) which put the flash about 0.5” from the subject. With the MP-E having a minimum working distance of roughly 0.7” at 5x, wouldn’t that place the subject inside the flash ring?
I plan to purchase this lens because of its 4 and 5x capabilities and I’d prefer to use a ring flash due to my familiarity with them. Will the above issue arise, and if so, is the MT-24EX the best solution?
