How do I decide on a camera/lens with high zoom range?
There are a lot of relatively cheap ~ 300$ (with body) consumer cameras with mega-zoom features — i.e. lenses with a 10-20× zoom factor for example Nikon p5100.
But for Nikon d5100 I have found only 11× lenses, and the price is quite high (example Nikon-AF-S-28-300mm-f3.5-5.6G-ED-VR-lens) ~ 1000$.
Is there are cheaper alternative? Perhaps there are some zoom filters or something like this.
I want to take portraits of wild animals, birds, etc. which are located 20-30m away.
