John McMaster Posted October 29, 2014 Share #1 Â Posted October 29, 2014 Advertisement (gone after registration) I have just bought an early 560mm f4.0, everything looks good other than it will not focus further than about 40m :-( I have tried with R9 and M(240) with similar results. It does not have any Series 6 filter but I would not have thought that would make the difference? Â I will contact Wetzlar but any ideas from here? It is so far out that something looks very wrong.... Â john Link to post Share on other sites More sharing options...

k-hawinkler Posted October 29, 2014 Share #2 Â Posted October 29, 2014 Could you please post an image of the lens, showing details near where it attaches to the camera? Link to post Share on other sites More sharing options...
John McMaster Posted October 29, 2014 Author Share #3  Posted October 29, 2014 Some quick phone snaps, to be focussing like this the tube would have to be extended...  http://johnmcmaster.com/lens/560-4/560-4_01.jpg  http://johnmcmaster.com/lens/560-4/560-4_02.jpg  http://johnmcmaster.com/lens/560-4/560-4_03.jpg  http://johnmcmaster.com/lens/560-4/560-4_04.jpg  john Link to post Share on other sites More sharing options...
Moritz Posted October 29, 2014 Share #4  Posted October 29, 2014 Hi John,  there must be always a series 6 filter in the Leica Apo Module Lens, while this is a part of the lens design. So this  will most likely cause your focus problem.  Best Regards,  Moritz Link to post Share on other sites More sharing options...
John McMaster Posted October 29, 2014 Author Share #5 Â Posted October 29, 2014 Thanks, I will track one down, probably from the USA... Â john Link to post Share on other sites More sharing options...

John McMaster Posted October 30, 2014 Author Share #7 Â Posted October 30, 2014 Advertisement (gone after registration) It is on its way from Germany ;-) I should be able to compare Leica 280/4, 560/4 with 1.4x and 2x apo converters and the Mamiya 300mm f2.8 APO plus 2x.....

John McMaster Posted October 30, 2014 Author Share #9 Â Posted October 30, 2014 Ah yes, the rear element is further back than the mount so will hit mirror I think... Â john Link to post Share on other sites More sharing options...
John McMaster Posted October 30, 2014 Author Share #10 Â Posted October 30, 2014 Another thing, while I wait on the Series VI filter, I assume that the knurled knob on LHS of lens mount is to rotate the lens barrel for portrait format? Lens seems to be stuck solid, no rotation... Â john Link to post Share on other sites More sharing options...
Moritz Posted October 30, 2014 Share #11  Posted October 30, 2014 Hi John,  on the older Leica APO 2,8/400mm, which is superior to the later module system, the screw you  described is to fix the focus point to a certain point. So if you shoot sports you can have the focus preset to  this point ( i.E. the goal) and reach it fastly with a turn.  Best Regards,  Moritz Link to post Share on other sites More sharing options...

John McMaster Posted October 30, 2014 Author Share #14  Posted October 30, 2014 Hi Moritz, there is another ring by the focus ring (so on focus module) which limits the close focus. You can see the arrow and locking pin in this shot http://johnmcmaster.com/lens/560-4/560-4_02.jpg  The one I am talking about is under (or to the left in this image) the Leica logo http://www.l-camera-forum.com/leica-wiki.en/images/thumb/6/67/R-telyt56f4.jpg/500px-R-telyt56f4.jpg  john Link to post Share on other sites More sharing options...
John McMaster Posted October 30, 2014 Author Share #15  Posted October 30, 2014 Thanks. So this might cause the problem!  Nope, that ring physically stops the focus going closer than whatever you set it to, does not limit the far focus  john Link to post Share on other sites More sharing options...
gbealnz Posted November 2, 2014 Share #16 Â Posted November 2, 2014 John, did you get a Series 6 filter? I could possibly lend you one to try, it would at least establish the issue or not? Regards Gary Link to post Share on other sites More sharing options...
John McMaster Posted November 3, 2014 Author Share #17 Â Posted November 3, 2014 Thanks Gary, should arrive this week to go with my Series 5.5, VII and VIII filters ;-) I do not think that will cure it, too far out as I tried my 280/4 with and without filter with negligible results, so asked Lacklands (NZ importers) to make some enquiries....

gbealnz Posted November 3, 2014 Share #18 Â Posted November 3, 2014 No worries John. And I tend to agree with you. I know from personal experience that the thickness of a filter makes a slight, but not huge difference to the focus point. Not as much as I guess you are talking, something is definitely wrong within. Gary Link to post Share on other sites More sharing options...
Mantice Posted November 5, 2014 Share #19 Â Posted November 5, 2014 Sounds like internal element may be out of alignment. If I recall correctly the focus limiter switch sets the minimum distance to infinity and not other way around? Link to post Share on other sites More sharing options...
John McMaster Posted November 5, 2014 Author Share #20 Â Posted November 5, 2014 Correct, limits the close point but can always turn (if not focus ;-)) to infinity. I now a have a Leitz Series VI filter which only makes a small difference, so it will be off to Wetzlar.... Â john Link to post Share on other sites More sharing options...
