Hi
Another question.
How much is aperture reduces when use SLR lens on dSLR camera. Crop factor for nikon is about 1.5 but what about aperture? Smaller sensor-less lights on it, but how much?
Thanks

The aperture stays the same. As the sensor will only take a smaller part of the total image that's being projected by full frame lenses, it will still get the same amount of light as a full frame sensor would (or full frame film would) at that particular area.

So a 50mm 1.8 becomes a 75mm 1.8
