Thanks, yes, the background is a bit distracting even though filtering ameliorated it somewhat flattenng the greens. There are two benches that have the most potential, but as can be seen in the other pict, the background for the second bench is nigh unusable.
In addition the 350 obviously doesn't do selective focus. I'm planning to set up the a7 there on a tripod triggered by the mobile thingy. If you wait long enough, something will inevitably happen. Unfortunately, there was a rather horrific accident at the station just recently where people apparently find it necessary to stream the entire misfortune live with the phone, instead of using it to call the emergency number.
That doesn't make me feel more comfortable setting up camp there.
