What is a good sub-250 $ for the Nikon F lens mount?
My wife and I are thinking of buying a Nikon D200 for a good price, but it comes with a lens. We are able to spend up to $ 250 on a target at the moment, and we are looking for a general-purpose lens that you can use to get your feet wet in a photograph more advanced. We're reading comments on a 50mm f/1.8 AF Nikkor Lens, for example, but are not educated enough about lenses and their pros and cons are comfortable making a purchase decision without further input. Help us out!
Best Purchase of $ 600 D200?
The 50mm f/1.8 lens is a great lens, but a focal length lens set, and proves to be a short telephoto camera Nikon DX series. In his budget, I recommend f/3.5-5.6 G ED from 1918 to 1955 ($ 175 on Amazon) I would recommend other goals if the budget were a little higher -. I warn you the D200 is not a beginner camera. It is designed for advanced amateur users professionals. It lacks many features of the nikon digital slr double-digit (d40/50/60/70/80/90) as scene modes, in order to control that more advanced users find useful, like a button to adjust the ISO, instead of having to dig through menus. To be honest, it's a camera for a beginner may be overwhelmed with, and have serious buyer's remorse. That does not mean they can not learn, but realize that this is a very useful tool for photographers professionals, and may not be such a good match for you as some other cameras. Good luck!
