I bought the RF 100mm L f/2.8 IS USM primarily for the IS combined with the IBIS in the R5 to help counteract my tremors. I have benign tremors, and at times, I shake pretty bad. Since I shoot most of my macro hand held, it's a struggle. Anyway, it's a nice lens but somehow harder to use than the EF 100mm L f/2.8 IS USM (I can't quite put my finger on it... yet), but that could partly be the R5. It's odd going to the MILC from my 5D mark IV DSLR.
My first impression is that the RF is a little soft. I had to up my sharpening a bit, but hopefully I will figure out the lens.
Funny thing, the first day that I used it, I had unlocked the SA ring and all of my shots were taken at -0.4 and that made all of my shots soft. I didn't notice the mistake until I started editing and noticed it in the EXIF data. The next day, I locked that sucker at 0 and things looked better, but as mentioned, just a little softer than the EF version. Since I was testing, I shot the same subject with both the RF and EF, except the wasps.

Thank you for the comps!
There are many species of Spider Wasp (Auplopus), the one I shot is Auplopus mellipes. The mason wasp is a harder call as there are so many species, most have no "common name". I'm pretty sure this one is Pachodynerus erynnis, but it may have different names in various parts of the country, like Red and Black or Red-spotted Mason Wasp. In Florida it's Orange and Black, LOL
