|There is definitely an issue with the shutter speed. At F10 there is no reason not to have the butterfly fully in focus. However, at 1/40, with a 105 macro lens, hand held, there is no way you are going to nail it with no movement from your part or the butterfly’s part. You used iso 100 why? At 400 you would have been able to bump up your shutter speed and have a perfectly sharp pic.|
PS: Sorry to hear about your mom.
