Another nice image...
I am glad you realize that my remark was intended to be constructive... it is often difficult to decide what to include, and to find a view point that allows you to get what you want into a rectangular shape - this is why I have a 10m tripod - to facilitate selection of a viewpoint which gives good composition of the main subjects... even if the foreground would not be good.
I was thinking that a viewpoint to the left of where you took the first photo would have given a view of the farm over the lakes... with a longer lens.
77mm is over three times 21mm, but my theory is to try to overcome this problem by having the ability to shift-and-stitch... I think I will get the Apo-Digitar 60, and, with stitching, that will give me a continuous range from 47, 60, 120, 150, ¿210? as all these lenses have large image circles suitable for shift-and-stitch.
It's funny you mention that - I was alternating between two lenses the whole afternoon, the 21mm with which I took this shot and the 77mm - which is my favourite lens. For some reason I only used the 21mm. I had to climb over a fence and poke the camera and tripod through a second fence to get the shot and perhaps that, along with the rapidly changing light, caused me to not try the 77. Having said that, I'm happy with the results of the 21mm. I would be reluctant to omit the dams on the left or the trees that are catching the light on the right.
Thanks to everyone for the feedback.
I took this one further along the road with the 77mm.
