Fujica

Hi, did anyone noticed a lack of quality with the newer Fujifilm XF lenses, too? I have 4 older lenses which have engraved serial number and are said to be manufactured in Japan and they are all excellent build quality with no issues at all. The two newer lenses I bought this year have a sticker with its serial number on it and are said to be manufactured in China. Both lenses have Quality issues I am currently dealing with and also the Fujifilm Europe Service until now was not able to solve the problems. The XF 18-135 doesnt fit well to the body of my X-E1 and has room while being attached to the body. The Service replied after I sent them the lens that it is within their technical specification. Well, although the X-E1 is not wheather sealed there would probably be an issue if this happens on a X-T1 body, because I assume with a slightly moving lens on a body the wheathersealing is not working properly anymore. The second lens XF 27mm has a big issue with autofocussing because it misses more than half of all shots. This one got exchanged. Surprisingly the new lens has exactly the same issue (also from China). So I am wondering slowly what happened to Fujis excellent lens quality... Anyone recognizing similar issues?

I'd take the combo: 14mm - 27mm - 60mm
