rscheffler Posted November 13, 2017 Share #1 Posted November 13, 2017 Advertisement (gone after registration) Wondering if other 28 Lux owners have come across this problem: play in the focusing ring that results in a 'dead spot' when switching focus direction. My copy of the lens currently has about 3mm play where I can move the focusing ring left-right, in the focusing directions, but it does not result in any change of focus (doesn't engage the helicoid). The ring feels entirely disconnected before it pushes against something underneath it. If I keep turning the ring once it 'engages' it then changes the focus as it should. It also moves freely in the north-south directions (if focusing is east-west). Recently I noticed a faint rattling sound of something like a loose small screw or ball bearing when changing the orientation of the lens. This happened all within the span of about a day a little while ago and have kept using the lens, in part due to reluctance to be without it for up to two months for servicing. Initially it was a very slight wobble that was annoying enough on its own, but quickly got much worse with the much greater and more annoying dead spot, as mentioned, of about 3mm. While I'm not the gentlest with my gear, I don't recall any specific incident that may have damaged the lens. I'm the second owner of this copy, received in nearly mint condition back in June 2016, and have used it fairly regularly since then. I thought it might be bad luck but this has now also happened to a friend's copy (that I have not touched ), which seems too coincidental... 1 Quote Link to post Share on other sites More sharing options...

darylgo Posted November 13, 2017 Share #4 Posted November 13, 2017 If the lens is not under warranty an independent repair could have the lens turned around much sooner. I wouldn't hesitate to use DAG in the US, direct communication with the repair person has advantages. 1 Quote Link to post Share on other sites More sharing options...
rscheffler Posted November 13, 2017 Author Share #5 Posted November 13, 2017 Thanks. I'm in Canada but know some up here have dealt with DAG and am considering doing so instead of Leica. Quote Link to post Share on other sites More sharing options...
rscheffler Posted November 13, 2017 Author Share #6 Posted November 13, 2017 I'm not expecting this will be a widespread problem since I haven't read any complaints about it before, but wanted to mention it since there are at least two of us with this problem occurring within about a month. Perhaps it's something that will start to appear after longer term use for some. Quote Link to post Share on other sites More sharing options...
anickpick Posted November 14, 2017 Share #7 Posted November 14, 2017 Advertisement (gone after registration) None of the three copies of the 28 Lux that I have handled had this problem. There should be zero play. 1 Quote Link to post Share on other sites More sharing options...
colint544 Posted November 14, 2017 Share #8 Posted November 14, 2017 I have the 35mm Summilux ASPH FLE, and it, suddenly, did exactly the same thing. Probably about seven or eight millimetres of play. Quite annoying on a very expensive lens. I'll just have to live with it until I can afford to have it serviced. 2 Quote Link to post Share on other sites More sharing options...
Bundestrainer Posted November 15, 2017 Share #9 Posted November 15, 2017 Just to let you know I'm the friend of Ron having the same problem with my 28 Summilux. My lens is under warranty and I'll be sending it to Leica CC at the end of this week. I'll report back once I've got the lens back. Quote Link to post Share on other sites More sharing options...
