One of the great things about spending time at Marks Hall is the variety of subject matter. This means, typically, that whatever lens you have on the camera is not the right one for the next subject, especially when mainly using primes.
I'd gone early one morning for the sunrise. After a few hours I stopped at the bench near Taxodium Swamp to sit and enjoy the surroundings. A short while later I became aware of movement behind me and to my right. Realising this muntjac was completely unaware of my presence I had to be quiet. However, my camera was on the tripod now propped against the bench, with a wide-angle lens attached. Moving very slowly I was able to remove the camera from the tripod and swap the wide-angle for a longer lens. Twisting around on the bench I managed to get a couple of shots before we made eye contact. After regarding each other for a few moments, the muntjac wandered off.
A satisfying morning.
