Sorry for the late reply, thanks for your workshopversion. I find it difficult to say, I looked at 2 different computerscreens. At the first screen I saw a thin line around the butterfly and flower, as if the sharpening is too much. But at another screen I didn't see it, so I found your workshopversion better there than my version.
Next time I will use another lens, I got now a secondhand 90mm lens, much better for macro than a 50-500 lens.
