i am very new to photography.
i am keen to find out more on this" Conversion Lens Adaptor LA-DC58K" from canon.
May i ask from fellow experts here, what is the main function for this conversion?
How does it work and for what purpose?
Example: my is nikon D90, if i am using 50mm f/1.4G and i need to add a addition lens infront of this 50mm lens, and at a distance of say 50 - 80 mm apart, do i use such lens adaptor?
And where can i get one?
sorry if i have ask some too simple question.
thanks a lot inadvance.
