Making a decision of buying a new dslr camera and as always research research research and more questions questions and questions come to my head. The point is why I should be bother in buying a FF camera if I can cover the focal length of view of the subject by the interchanging the lenses available on the market?
Obviously I am not a professional photographer where I could understand this but taking into consideration that I am more for landscapes and street photography rather than portraits, would it make the difference?

I didn't find the right solution from the Internet.
