EM1 Mark 2 Sample Macro Shots

Finally got my hands on the EM1 Mark 2 for a quick test. What do you think of these shots?

Gasteracantha sp.

Thalassius sp. (Fishing Spider)

Talthybia sp. (Wrap-around Spider)

I have been using my workhorse, the EM1 mark 1 for the last 3-4 years. Do you think i should upgrade?
