hey fellow clubsnappers,
i am new to the dslr world and i have some questions to ask you.
i own a nikon d50 and a kit lens 18-55.
the questions i want to ask are:
1) what is the connection between the f number and the numbers on the lens such as 18-55mm? what does a larger/smaller f number mean? what does a smaller mm mean? and whats the connection between them?
2) is it similar if i have a 18-55 lens and buy a 55-200 lens, than buying a 18-200 lens?
thank you fellow clubsnappers. ur response is deeply appreciated. i really want to delve in deeper into photography and i get frustrated when my pics are not sharp enough or out of focus.
