Originally posted by UncleVanya I’ve seen good shots but I’ve seen far more than aren’t great. I tried one but it could just be poor technique but I’ve used other long lenses with less difficulty.
It's not an easy lens to use, and color fringing is a significant issue at the widest apertures, but in terms of sharpness the lens is the goods.
The fact that I can shoot a roaming fox near 8 pm on a cloudy evening, and get good fur detail with the lens wide open, has me enthusiastic about the K 500/4.5...
I wouldn't recommend it to the OP, though, because there definitely is a greater-than-average learning curve with it and he seems prepared to spend a more significant amount of cash for a better, more convenient solution.
