Trying to install my Contax Metabones adapter now but the lens falls out EASILY upon use. This is very scary. Focusing is great, very smooth, and akin to the 14-45mm ring (okay, maybe not that smooth.. but does feel like it 'belongs'... and when it works, it works.
When I adjust the aperture, the part of the lens body that rotates to secure to the adapter doesn't seem to 'click' into place (or secure into place for that matter.. it freely moves like a focusing wheel, and if you aren't careful enough while adjusting aperture, the lens will come out of the body -- which is a huge problem).
Is this a problem with my lens or the metabones adapter?
Hi,
It's not a lens problem and it is not an adapter problem (from a technical point of view). Then again, it is an adapter problem as mounting and un-mounting the lens and adapter isn't very intuitive and basically this is an user error as you didn't get it right...
English is not my strong side, nor is peadagogics but I can try.
1: Make sure your lens is unmounted correctly. You can't open the aperture blades all the way up and the aperture scale is seemingly un-aligned.
2: face the lens downwards
3: Have a look at the adapter from the camera's angle of view. There is a sliding switch which should be positioned to the right.
Now look at the lens and the adapter and find the correct way to align them.
4: Here you may have to align the adapter focusing drive tip with the lid on the lens' focusing screw. Then push the lens and the adapter towards each other (the same way you mount the G lens to a G camera or any other adapter) without turning anything. Turn the knurled, or grooved, ring just in front of the adapter focusing ring only (meaning you should try not to touch any other ring or part of the lens barrel) to the right seen from the front of the lens. That is the lens "mounting ring" and a special for these G lenses.
When turning the mounting ring some power is needed. It is a tight fit and you turn the lens mounting ring until the whole thing clicks in place. The click comes from the adapter locking pin falling into place, a small lid, to the lens. You can see this happen from the adapter side.
5: Now again look at the adapter mount surface (the side mounting to the camera) and push the sliding lever to the left locking the lens to the adapter.
6: You should now be able to turn the aperture ring and see the aperture blades open and close corresponding to the marks on the lens.
7: Mount the lens/adapter to the camera. When locked to the camera the lens will now align correctly with the aperture index mark facing straight upwards. Done.
Yes, it is fiddly. All G -> µ4/3 adapters I have tried are fiddly in some way and this one is perhaps the worst. Maybe it is needed with this construction for a very safe lock between the lens and the adapter. Maybe it is a sign of a design that could be done better. Whatever, after some practice it is easier to do than describe.
I tried this procedure twice with my Planar 45 just to check I got things right. Still, I may have missed something.
I hope somebody fluent in both English and mechanics can describe it better later and that Metabones include a user guide with their adapters. The box is nice though...
