Olympus 100-400 mount problem?
1

I bought the new 100-400 Zuiko and I am happy but I find a little bad problem with the mount.

The lens has a little movement with my all 3 cameras (Pen-f, em1 mkii and em5 mkii) and with mc-14 .

I show you a video: Can be normal in this lens for size and weight ?

My panny was the same, never had an issue. The Oly is the same, not going to worry.

Read about a few of these loose fit issues for some people, but not all. This implies inconsistencies. I would give Olympus a call and hear what they have to say. For this price, a loose fit might work just fine but it can be annoying, even more so when the time comes to sell it.

I called my support and I explained the situation.

They told me that the movement can be a tolerance problem for camera mount because every lens is tested first to received the quality ok.

I explained that mount has a differente hole and  that with 3 cameras I received the same problem and sound.

They decided to test my 100-400 and search for the origin of the problem because time to have a new 100-400 is very long (about 40-60 days).

No, not a problem

That slight twisting slop does not change the distance of the lens from the flange at all, as far as I can see.  Therefore not a problem.

Keep us posted as to how it worked out when it comes back

Could be a problem when it comes time to sell it. Also, not sure, but wonder if twists and turns offset some of the dual sync ibis 🤔

It is a problem for movement and bad sound .

I will post here some videos for understand the really difference between an zuiko lens as 40-150 pro or the 1,4x and the 100-400:

Most of my lenses, both m43 an Nikon Fs have a very slight mount play when mounted on the camera.

But none has the amount of play you have in the clips you have posted.

I hold the truth... A very specific, based on my experience and only relevant to me truth, but the truth nonetheless!

Minor rotational movement on the x about the same as the 300mm f4 and 1.4 tc on the em1 Mark III

Can you insert a photo of the lens mount?

I handled 100-400mm today

I was at Yodobashi today and looked at the 100-400mm. It was mounted on an E-M1III. Although I knew the lens was rather large it still surprised me a bit as to how big it is. The 75-300mm was sitting right next to it and there is no comparison as to size. I noticed that the 100-400mm when mounted on the camera could rotate a small amount.

Re: Olympus 100-400 mount problem?

The only problem I can see is that the weatherproofing around the lens mount is compromised. Perhaps it is the rubber seal that is not thick enough to to tighten up the joining of lens and body.

I have had various camera systems over the years and with one or two exceptions there has always been a varying amount of rotational play in the lens/camera interface. I had one body/lens combo that had enough to lose connection at times and I chalked that up to both the body and lens being at the ragged edge of their respective tolerances. One cause of excessive play could be that the in your case, the locking hole in your new lens is oversized and allows the lens to rotate an extra amount. Since it seems to be the same amount for all your devices, you should ether return for one that you are happy with or let Olympus take care of it under warranty. On the other hand, if it works on all of your devises  without a problem and is sharp, I would be inclined to keep it. Now if it is bad enough that you can feel the movement simply zooming a lens then that would bother me.

The official answer from Olympus is :”It is normale and all 100-400 have this game/play”.

I decided to leave the lens in the store because i can’t use a lens with click and game every time i zoom from 100 to 300-400mm.

It could also affect the weatherproofing.

For Olympus until electronic conctacs works the problem is normal
