Should I buy an inexpensive zoom lens? 400-500mm There are a number of these lenses available on the market and on ebay. I am intrigued, but most likely wouldn't use them that often. I have a use for them. Crows. gulls, and other birds. I notice they are slow and don't have a tripod collar. What are the plus & minus's?

Plus - They're cheap (inexpensive) Minus - They're cheap (poor optics) Plus - They're cheap (poor optics can still be cool and maybe they're good enough) Minus - They're cheap (maybe the optics won't be good enough)

Thanks for responding...I have a 300mm zoom that is great by Tamron and was hoping someone could give me their experience w/one of the number of lens available. Maybe, I could pick up a recommended used one...CHEAP!

400mm, 500mm, or 600mm mirror lenses, also known as reflex, or catadioptric lenses. Pluses: Very economical, can be had new for $150 (Vivitar 500mm f/8 Reflex) to $400 (Sigma 600 f/8 Reflex). Generally quite sharp even though construction is fairly simple. Compact size and lightweight (though tripod mount is preferred to hand-holding). Minuses: Aperture is fixed, usually at f/8. Manual focus. Highlights are rendered as doughnut shapes (sometimes a distraction, sometimes an interesting feature).
