SR setting, vintage FF lenses

Hi - just a quick question. When I use a vintage manual or A lens on my KS-2, the camera asks me for the focal length so that shake reduction is correct. Do I enter the actual focal length of the lens, or (since I'm using an APS-C sensor with a full frame lens) do I multiply by 1.5? Any help appreciated!

I've seen varying advice for this, but the concensus seems to be - Simply enter the actual focal length. In the case of a zoom lens, enter a value half-way between the upper and lower length. So, for a 35-70mm lens, 50mm entered will be OK.

True. If it's an APS-C camera asking for the focal length, it doesn't care about the "crop factor"...it just wants to know what lens you've mounted on your camera.

Yep. And if you upload your photos to Flickr or some other image sharing site, the focal length will frequently be displayed, so you want that to reflect the actual lens you used inasmuch as you can.

Set the actual length, that way it also keeps the metadata correct too.
