hi all...

I am new in this community.
Despite some experience loooong time ago w a k1000, I am totally ne to the dslr world + fund it overwhelming.
I am currently trying to get off the ground using:
- a k200
- 18mm-55mm
- 50mm 1.7
- 70mm-210mm
- & lightroom
I do appreciate your patience as I will be asking some seriously novice questions to start with.
My first question is w respect to using the 50mm 1.7 lense.
As I turn on the camera it asks me to choose a focal length...
Can someone please explain why the camera is asking me for a focal length?
very much appreciate + much more questions to follow...

The camera is asking for the focal length so that the SR (shake reduction) system knows at what level to operate.

Welcome to the forum, in answer to your question just to set to 50mm for that lens, as Adam says it's for the Shake Reduction system, so it knows what lens your using.

Later lenses actually have more electrical contacts, so they speak directly with the camera, so it doesn't need to ask.

Thanks for your response.
I get to choose w/in a range of 8-350... what is optimal?
I originally thought it was trying to determine whether to shoot wide anlge [lower focal length] or not...
