After 4 years of my monogyny with my 28-80mm lens I have purchased a new lens!. All these days so many people have asked me 'how many' lenses I have and why I haven't bought more lenses. I strongly believe that wildlife photography is far too beyond just buying a 500 mm lens. I have seen so many people buying costly equipments and not using them, (no offense to those who buy and also use).
