Twas iso 800
Additionally it was near 7pm when I took them, so it was daylight, but hardly bright, and the camera was 18" from a crevice in the corner of my garden, so lighting...wasnt that hot!
I took some at 200, they looked the same bar less noise, and the mouse being nothing but a blur. I didnt know how many times Id be able to get it to come out so decided to whack the iso up to 800 to make sure I could get it unblurred. They were taken with the 17-85mm lens which isnt that fast. Theres always another day to try again with the 50mm prime, close up filters and lower ISO
