Assuming it is a sunny, well-lit day, what is considered an affordable non-prime super zoom (100-500 region) that can dependably freeze action? I've seen the Bigmos, but was wondering if there were other lenses with possibly larger apertures for the same price region. I have a feeling that wouldn't be fast enough for outdoor sports with faster action (volleyball, soccer, skatepark, basketball).
This would be a complement, or even a replacement if good enough, for my 55-250mm lens. It will obviously also double-duty as a wildlife lens.
