Eye eye ... I can see you

Well I also just found this on

The Zuiko Lenses That Never Made It

Then there is the 'L. Zuiko Auto-W 18mm/F3.5' prototype with 12 element in 10 groups, and a fixed 72mm thread. This version was never marketed. The final version is multicoated (Zuiko MC 18mm/F3.5), has 11 elements in 9

So it seems it was never marketed, how interesting! I wonder why they dropped the front design?

Hi all,

there may be an answer to this or then again maybe not...I've had a couple of these 18mm lenses in the past, I found it to be a very good lens and one I enjoyed using very much, so much so that I still have one in my lens drawer, however when reading through some literature I noticed that the original version has a fixed filter ring around the top as opposed to the more common 49>72mm adapter ring setup.

I would love to know from anybody if they have actually seen a version of the 18mm lens like this with the fixed filter ring

Also note that the newer version or the one I and other are more familiar with suggests that it is currently in development, although the original version with the fixed filter ring does not mentioned being under development which assumes this was in circulation before releasing the updated one?

Original version, text taken from The World of OM-Systems - Franz Pangerl and early OM System Manual for Zuiko Interchangeable Lenses Group

The newer version of the version - Text from 2nd Edition The World of OM-Systems Franz Pangerl and newer version of OM System Manual for Zuiko interchangeable lenses group

Thanks

Hi,

Apologies been away for a couple of days, I've attached a picture that will hopefully highlight the part Crumbo is referring to, if you want it let me know if you want it, I have plenty, I'm sure we can work somehting out.

Kind regards

Hi, thank you for your reply!

 

 

When I raise the mirror by finger it goes all the way with no sticking. What exactly is the mirror lifting bumper? If it is the small piece of foam that keeps the mirror from hitting the top of the mirror box when it is raised, then I believe it is fine at the moment.

 

When I first got the camera when the shutter was fired the mirror would do a small little jump (as if it were wanting to lift up), but it would only be a few millimeters. Since that side of the mirror box couldn’t complete the full cycle, I would use the mirror lock knob to reset it, which would complete the firing of the shutter. If I leave the mirror locked up, the camera is able to fire on all shutter speeds just fine.

 

I am beginning to believe that the mirror lifting spring does not have enough tension, since there is no other obvious mechanical failure. If there are any other photos of videos I could show you to help you see the issue, please let me know! Thank you so much!

Hi,

When I say bumper I'm thinking about the shock absorber bumper which is on the other side, these can wear and is part of the lifting mechanism, it's a difficult one, when the camera was together did you ever try pushing the mirror up with your finger after you had fired the shutter to see if it completed the shutter firing cycle?

As I say happy to send a spare mirror box if it may help.

Kind regards

Hi,

I've attached some picture of a complete OM1n Mirror box that may help, I'm not sure what state yours is in but I assue the mirro lifting spring has enough tension, also when you raise the mirro by finger soes it go all the way without any sticking or juttering? One other thing, when in the chassis the mirror lifting bumper may be degraded or misaligned, finally when it was in the camera did it lift to a certain point but not fire the shutter or just do not lift at all?

If it helps I could post the one in the picture, I'm in the UK, but if your outside the UK it may be cost prohibitive.

Hi,

Did you get this sorted?

Kind regards

@conmai

Very nice image - I'm envious ! Might I ask, however, if you could post smaller images in the future, please ? The usual guideline is not over 1000px on the longest side, so that they load more quickly ? Many thanks.

Hi Tony,

Yes of course, thanks for the heads up.

Kind regards

Beautiful color and detail.

 

I assume you were using a 4/3 system camera body.Will you post any more shooting data, please?

Hi,

Yes of course, I was using an olympus om-d e-m10 mark iii with the 60mm Macro lens, the image was cropped a little, I cannot fault the lens and really is one of my favourite modern lenses, I do however spend alot of time using manual lenses.

Kind regards
