What a happen-stance,. When I was taking Infra-red pix with the A350 Sony  a woman asked me if it would interfere with my photography if she continued walking down the track.

I told her no problem because I was going to take pix of the old road bridge looking north rather then south. After I had done that I grabbed the A77 and took several shots with the 18-270 Tamron. She was wearing a bright red park type coat that showed up well so I got a couple of shots when she was in the distance.with the lens at 270. 

Balanced the picture very nicely. I think I need to go down the track with the Smart Idiot and get some tele shots of the bridge too. Must wait for nice sunny day, but they are forecasting heavy rain.
