I took this picture on Friday with my Leica S007 and HC300mm using the Leica H to S adapter............There is this horrendous ghosting going on and I have no idea why.........many of the pictures have the same ghosting

i thought the HC 300mm maxes out at 1/2000 ?

 

looks like a shutter problem..could also be the adapter not the lens

Pure speculation, but were all of the blurred shots 1/750?  Since the HC lenses only go to 1/800, maybe there is something wrong with the shutter and it is only noticeable at the extremes.

my lens is the 1/800 model. Not all the pictures are messed up, which you would think they would if it was either of the lens or adapter..........

Strange

EXIF data from a shot that was good would help. 

 

This one looks okay

Neil, same phenomenon with native lens?

With the S120 lens no such issue......right out of camera with NO PP 

 

I went for lunch with the owner of Leica Malaysia today, he said he will take my adapter to Germany on Thursday and have Leica check it out............he is going for the Leica C-M Launch :)

This one was a simulation of yesterday shooting hand held.............I missed the focus but still no ghosting so Im confused now

Were you hand-holding the 300mm in the problem shots?  If so, it is camera shake, a leaf shutter does not stop motion as well as a focal plane.  I think in my Hasselblad days 1/500th on the leaf shutters had an equivalent to /125th focal plane......  So similar to trying to handhold a 300mm at 1/180th!

Yea mate that’s what I’m thinking was the problem as well........... it’s al a little heavy to hand hold for any leinght of time

I notice that the problem images only show the double-image towards the top of the landscape-oriented frame (man with red scarf; girl head shot), or to the left of the (one) portrait-oriented frame (girl in red dress) you've included. Depending on which way your hold the S, is this in fact the same side of the image frame? (I'm still thinking about a reason for this!)

Lenses with leaf-shutters that are also designed for ttl viewing (like the Hasselblads, and of couse, the Leica CS lenses) - have a double-acting shutter. That is, the shutter has to be open for viewing, and then close, and then open again for the actual exposure, and close again, and perhaps open again after the exposure "black-out."

 

It is more or less like the shutter action in most higher-end "live-view" cameras - shutter open for viewing, then closed, then open/closed again to time the actual exposure, then open again.

 

Hasselblad CF lenses for the V system do this, but they also have an "F" setting, to lock the lens shutter open (disable it) for use on the focal-plane shutter bodies (2000FC, etc.), and then operate only using the internal camera focal-plane shutter, just like "shutterless" Nikon/Canon/Leica-M or R lenses.

 

Do the HC lenses also allow locking the lens shutter open for use on focal-plane-shutter bodies (e.g. Leica S)? Is locking the HC lens leaf shutter open user-optional with a switch? Did you set it correctly?

 

Looks to me as though there is a lag going on, wherein the Hassy lens is still open in viewing mode as the S camera shutter opens, and then "cycles" during the camera shutter exposure. Two exposures within the single camera-shutter exposure. Which would also explain Richardgb's observation - as the S focal plane shutter slit moves across the sensor, the lens-shutter "viewing" exposure ends and its "real" exposure begins, leaving only one image.

 

Lag could be due to misadjusted HC lens, or misadjusted adapter, or to the double sets of contacts in the adapter (S signal to adapter and then adapter signal to HC lens, perhaps with brief "processing" or "translation" of the signals (from "Leica S language" to "Hassy-HC language") within the adapter).

 

Another possibility - according to B&H, Hassy makes a special aerial-photography version of the 300mm HC - with a strengthened lens flange/mount to prevent this heavy lens from "flexing" on the camera mount. Could it be that between using the "normal"-mount version, and having an adapter between the lens and camera (another connection that might flex) the lens is just wobbling during the exposure, far more than traditional "camera shake?"

To add to Andy's good suggestions, the OP might check if he is using True Focus, which does not work properly with long focus lenses.  Also, be sure to press the shutter release halfway before the second detent which trips the shutter in order to give the autofocus a moment to lock in.

Seems to me as if the FPS is already open while the CS of the lens hasn't closed yet to then open again, resulting in sort of a double exposure.

 

Or it might just be camera shake... I only like shooting the 300mm hand held at 1/2000 or 1/4000 everything longer and I got less than optimal results.
