The implications of the comments on this topic are very interesting.
I'm fortunate to live in one of the Worlds top Birding spots, but I'm retired, not exactly penniless but its really just a matter of degree. Some very rare and endangered species of birds are my neighbours but the lens etc to photograph them to the standadrd that I want is just beyond my reach.
If I could use something like a 600mm mirror lens and then enhance the quality with Photoshop (I'm fairly au fait and use it for Landscape photography) I could really be in business.
Just how feasible is the idea? Can anybody show comparitive results between a Mirror lens and, say, a 600mm f4 Nikon, where the end result of the Mirror lens has been Sharpened and Contrast improved with Photoshop.
What could be done to improve the Bokeh? I really don't like those little half moons!
Is this the way we are going? Do we no longer need the fabulous lens, the Zeiss Planer, the Novoflex etc of the past. Anything will do and we can enhance the result with Photoshop.
I'm not sure how far my tongue is in my cheek.
Norman.
