 My 35 lux FLE focus ring is stuck and loose with out any apparent  reason. Bought new 3 years ago. Just sent in for service. Any one reporting same problem?

I've had my 35mm Summilux ASPH FLE for six years. I bought it new. It has always had a distinctive rattle, and a slack aperture ring, but about a year ago it also developed a little play in the focus. Everything (apart from the optical quality, which is superb) just feels slightly sloppy and second-rate. Bit disappointing because it hasn't been heavily used, and I've looked after it. Also, it cost £3600.

 

In contrast, my battered 1960 35mm Summaron F2.8 operates with jewel-like precision.

Floating elements are the culprit i suspect. Three of my FLE lenses (35/1.4, 50/1.4, 70/2) have got focusing issues more or less. I would not ask for a FLE version of the 90/2 apo for this only reason.

 Yes. I have been thinking the floating elements could have something to do too.
