12 f2 made in china really tight to mount

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".

oh dear my OM-D is made in china.  I guess its destined to spontaneously implode or do something just a remarkably impressive as it is made in china.

You do have a choice, just don't buy oly gear.  there is fuji, canon, nikon...  all of which have MIJ bodies/lenses for you to avoid the made in china problem you seem to have.

Whether it's made in China is immaterial. Japanese or German or <insert country here whose trade practices are favorable to American sensibilities>'s manufacturing is not inherently any better than China's. In fact, dollar for dollar, China is doing by far the finest manufacturing in the world. This is a fact. It's not even about saving on labor costs anymore: China's manufacturing centers are better equipped logistically for manufacturing than Japanese or American manufacturing centers. What matters in the end is the design. Regardless of where it's being built.

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.

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.

Ultimate responsibility for quality rests with the company that puts their name on the product. Apple 's product are made in China to high standards. If Olympus is going to put their name on a product, it is their responsibility to ensure that the quality is the same regardless of where it is made.

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.

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.

It's a tight twist, as is the Panasonic 20mm lens I've had for a while. It's been discussed before, and there's been no reports of issues arising from it.

Have it weared in over time and become loosened? thanks.

It may have to some degree (I'm not sure it's that, or I'm just used to it). The tight fit lenses are still a tighter fit than all the others (after 2-3 years). Some adapters and lenses that are looser have rotational play (where the tight ones don't). I only think about it when it's raised in discussions like this one. These differences in fit tolerances are of little significance and concern.

"of little significance and concern"

suppose say I am going out to shoot a little film with my new GH3 in the near future consists merely 30 shots, use only two lens 12 f2 and Canon 50 f1.8, half the shots with 12 f2. In most extreme case I will be mounting and dismounting 12f 2 for 15 times. (The shots must be taken in sequence for video production of course). That comes to 15 mount +15 dismount =30 time struggles for every small video shoot out, if this is true would you still think it is of little concern in this case? I will not be taking two cameras body with me for a while. thanks.

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

All I can relate is in over 2 years with quite a few lenses, I've used the 20/1.7 a lot, and changed lenses more than a few times.    In addition, I've been following user experiences here just about daily.   There's usually one odd report about something most don't encounter issues with.

The most negative report on the tightness has been only about concerns - there's been no evidence I've read of which would suggest there is a reason to worry.   And my own experience supports that.

The concern with alarm usually comes from those that don't have a lot of experience with interchangeable lenses.
