Dear members, I got an estimate from Leicashop in Vienna http://www.leicashop.com/ for installation of the 2nd cam to my summicron-R 50mm. It`s 240 Eur. I think this is out of proportion, since their estimate for leicaflex SL CLA is 150-200 Eur. But to be fair, the lens also has some haze/fog that can only be seen looking trough the lens against strong light source and black background and at certain angle (I hope I have explained well to be understood). I got the lens from their shop with designation "clean lenses..." AND for this reason they are willing to clean the lens for free. This is I believe very fair, because their money-back guarantee expires 14 days after the purchase (I bought the lens last september). So tell me should I send them the lens or buy another 3 cam lens (no problem for 240 Eur). Thanks, Miha
