watched the spider catch the critter then it jumped on my lens to challenge the reflection of itself .the critter was the size of the springtail/spider mite
... moving quickly with the MP-E ? ..ha ha ha aha hahah
i originally wanted an MP-E for field work. When i found out i could no longer do field work i got the MP-E anyway and turned it into a dektop rig instead. It has been an absolute delight in that capacity when tethered with a stackshot rail.
