I also use a wired release when possible, and it definitely helps. I wasn't sure if you were maybe using a focus rail or something.
I wish I could get my subjects to hold still! ๐ From the wind blowing flowers and leaves around to insects and spiders flying/running away it can get frustrating! I can definitely see why many people use a 90mm or similar for insect macro. Unfortunately the Olympus version is a pro lens, and $1500 is a good bit for me to cough up right away. So I'm keeping my eye out for other options!
