D50 Questions

[mcdiejdh]

Had my D50 for about a week so just getting to know it but I have a couple of questions:

1. The autofocus brackets when lit (active) have a thin line that runs to the edge of the viewfinder, is this normal or a fault .

2. It is often quoted that D-SLR have a focal range of about 1.5 x the lens focal length. Is this also true of the Nikon DX lenses.

Thanks

I get that too, nothing to worry about.

Aprrently so. I have been reading up on the 18 - 200mm VR lens which I have just purchased and every single review says it in an equivilent to a 300mm film focal lenght. The DX means it has a smaller image circle so it is only compatible with the APSC DLSR camera. It also helps to prevent vignetting.

It's just the LCD connection for the autofocus indicators. Pefectly nomal

It's not an actual magnification, but a crop factor......I'm not on my own PC, and don't have the link, but a quick Google on "DSLR crop factor" will enlighten you further....

What that means is the field of view is equivalent to a lens that was 1.5x longer on your sensor because the image is "cropped" by the sensor only taking up a portion of the projected image circle, compared to 35mm film/sensors.

That means it is true of ANY lens you fit to that camera, as it isnt a trait of the lenses themselves.
