<p>Some one said me that my photography art is being killed by the lens I have. According to him for a lens of 18-140 mm, the lens factor that comes to play is 140/18=7.777 which is too bad. This factor should never be more than 3. For example Tamron 17-50 (<3) is a good lens but Nikon 18-55 mm (>3) is not a good lens whereas canon 24-70 mm is a masterpiece </p> <p>Is the information correct? </p> <p> </p>
