I recently brought a 12 f2 from B&H and surprisingly found it is made in China:-( as stated on the outter box and at the back of the lens. It has a big issue of being really tight to mount onto my GX1, I have to really force it. Tried in local store, an saleman says it's reallt tight to mount on a store GX1 as well. Tried other Olympus lens mount on easily onto my GX1 (Such as 17 f2.8). Quality wise it's not sharper than my 14-42 powerzoom. Anyone has experience with 12 f2 on Lumix body, especially GX1? Does yours mount on easily? Is it made in Japan or China? Should I return the lens? Any input is much appreciated.:-P thanks.

Try using a squirt WD40 on the back of the lens mount and it should go on and off your GX1 smoothly.

Or you could exchange yours for a MIJ copy.

Good luck whatever you decide to do.

Good luck is what they will need if WB40 is used on lens/mount.

More than luck I would think. They would need a miracle not to mess up the lens and camera.

Not sure where you get that information from. Much of it is about saving labour costs, saving money through lack of legislation and having a production facility in the fastest growing market in the world.

It does matter where it's built. Many of these companies are having the assembly carried out in China but the hi-tech manufactured parts are imported. There is a huge amount of technical daily support that goes into manufacturing cutting edge technology.

Try manufacturing a Euro V or US10 diesel injection system in China, or a precision internal grinder, or a electro discharge machine, or a compliant explosion proof electric motor. There is a very long list of everyday equipment that can only currently be manufactured in a handful of places.




I'm not saying China will never catch up as clearly they will but currently the manufacturing capability is not at the same level as Japan, US, Germany, UK, Sweden etc.
 
bought mine 12/2 in early June. No issues with mounting on EP2. Super high quality in IQ and everything else. From my experience there is always a difference between Japan, Germany OOH and China OTOH. If I had a choice for high-end products origin I would never buy "made in China".

Manufacturing is about process, equipment and quality control, which is also mostly process. Strict process reduces human factor to a minimum, so it doesn't matter where stuff is built.



FYI, Nikon 105mm F2.8 VR is an excellent lens that costs $900, and it also has been made in China for years. How does that correlate with your theory?
 
and mind your own business. I know without your stupid advice how to spend my money.

Never worked in lens manufacturing but I would imaging that the glass elements are ground outside China and the lens is assembled and tested in China.




It's not a theory, if we talking about manufacturing capability Japan, the US and western Europe can manufacture things that China simply can't even is they buy the same processing equipment (which never runs itself without support, even highly automated FMCG plant needs technical support). That comes from years of experience working in NPI of cutting edge products and working with manufacturing facilities in the US, UK, France, Sweden, Germany, India, Turkey, Mexico and China.

You can't manufacture many cutting edge, high precision, high endurance products in China at the moment. The products I stated are examples of that within automotive, there will be other examples from other industries. You can't manufacture them in China, the skill base is not currently there.

Nooo!. No WD40 near a camera. Insead, use the 40 year old technique - nose grease. Just wipe your finger on the side of your nose, and rub it on the camera mount. Safe, convenient, and you can do it as often as you please.

if you get oil into the shutter blades it will spray it all over the sensor from now to eternity.

Really, Len_Gee where did you come up with that idea?



I would call Panny and see what they have to say.

Chinese quality is very good - more than 1 Milliarde human power - the overtaking us all at some point: high quality made in China is awesome - a bit of spit on the bayonet connection and you can do it on it can always ;)

You crazy. Don't tell him to spray it directly on the lens mount. He can spray it on a napkin then apply it. He can even use a little olive oil using his finger to spread it on the mount. Spread a very tiny amount of it on using fingers and use a towel to dry excess oil off, that will leave a thin layer of oil that won't drip anywhere.
