How does M8 effect focal length of lenses

How does the whatever in the M8 effect your lenses? I konw there is a 1.33 crop factor which will effect the field of view (which may actually result in better pics, because I've always held that photography generally has to do with the close view), but does it effect any other aspect of the lens?

No, not really, the lens is still the lens. The FOV crop is the only key change happening.

Switch a lens from a film camera to the M8 and all you will see is a cropped image. To obtain the same field of view from the same shooting position, you will need to switch to a wider lens which will provide greater depth of field, so to counteract that, you need to shoot at about 1/2 a stop wider open.

What about depth of field? If I use on M8 a 21 mm I'll got 28 mm., but preserving the same de:confused: pth of field of 21mm. Is it true?

 

I'm sorry if it is an old question in de Forum. But I did not find it.

 

Thank you.

Yes, depth of field is related to shooting distance, aperture and focal length, none of which are affected by cropping the image. However, to get a print of the same size, you'll need to magnify the image more which will reduce the apparent depth of field. Roughly, you'll need to open the lens half a stop to get equivalent depth of field.

 

Depth of field is all an eye-thing - how big imperfections can to be before the eye registers it as unsharp.
