Frame line issue?


Recommended Posts

Advertisement (gone after registration)

Hi all,

 

I bought an M262 yesterday with a 50mm summicron and am hugely happy!

 

One minor thing - what I see inside the frame lines is actually quite a bit more than what I see on the final image. Is this normal? Taking a photo from a distance of 2-3m with with a row of wine bottles towards the bottom of the frame lines, the image captured cuts off pretty much the whole bottle

 

I've manually selected the lens type from the serial number (as it doesn't have 6bit coding) but is there anything else I have failed to do? Or does this sound pretty normal?

Firstly, the frame lines are set mechanically by the mount flange on the lens. 6 bit code has nothing to do with the frame lines.

The accuracy of the frame lines per the distance to the subject take a little getting used to. With a little practice you'll get it.

The frame lines are accurate at one distance only, which varies between 1 and 2 m. depending on the model of the camera.

As the focal length of the lens varies with the focussed distance this cannot be anything else, except if Leica were to introduce digital frame lines at some point in the future. Until then, the frame lines will be too narrow at infinity and more or less accurate close-up. Most experienced M shooters tend to frame a bit loosely at shorter distances.

Ahhhh that make sense. Coming from DSLR to the rangefinder I just assumed it wasn't accurate and "close enough" .......so I left a little room around what I wanted and moved on.

 

Thanks Jaapv for once again explaining things simply.

If i am not mistaken, 262 works with 2 meter.

Yes, all M240 based cameras have frame lines optimized for 2m, like the M8.2. Other digital M frame lines are optimized for 1m.

 

This should not be confused with the focus patch, which is set at a virtual distance of 2m for all these versions.

But- as the viewfinder is not in the optical axis, it will suffer from parallax perspective shift, which, despite the framing being correct, can give surprising results.  Yes, it does correct for parallax in the plane of focus, but everything before and behind that  plane will be shifted to a certain extent.

I made a somewhat primitive sketch, hope it makes things clear.

That's a little exaggerated.
