Back in the M43 game

I bought a M43 OM-1 and enjoyed it, but then decided I wanted to go all in on full frame. I lugged my FF kit all over the east coast this summer on a vacation and realized it was just too much weight and not enough options. So I am back!

Shot with the OM-1.1, 40-150 2.8, f2.8, 1/1600, and Auto ISO. Edited in lightroom to remove noise, adjust exposure, crop, and sharpen. I am totally impressed with the 40-150 2.8. I wish it was a little longer in reach, but wow is it sharp. I had the 100-400 before and I am debating picking up another for animal shots etc. but I am worried the resolving power of this lens has ruined me for that one.

Nothing special, just an Iguana and a dove.... If anyone has a recommendation for which lens to pickup for reach other than the 100-400 that would be super sharp, but compact enough to travel with I am all ears.
