I just got this nikon D40 with 18mm to 55 mm and I plan to purchase a longer range lens.
I when though my previous photo that was shot using olympus C5050 with nikon picture project to see what range I normally took.
The focus length from various photo is inbetween 5.6mm ( wide angle ) to 23mm ( telephoto)
Now I am confuss and do not know whether should I go for max range of 135mm or 200mm.
How to convert the foucs length to the exact figure.
