Olympus 1.4 converter

Hi -

Last weekend all was well - today when photographing a kingfisher I couldn't get focus using the converter with the Olympus 40-150 lens. Fortunately Anne was with me and I was able to use her lens+ for a few moments before the bird was off. I had the Olympus 12-100 lens which of course didn't have the reach same as the 40-150 on its own.

Any ideas or suggestions to the sudden failure of the converter would be welcome as it seldom leaves the body.

Re: Olympus 1.4 converter

I have heard mention of the screws coming loose on the face plates - not sure if it is relevant but it might put something out of kilter. Contacts is the other thing, it would be worth giving them a clean.

Re: Olympus 1.4 converter

I have had the problem of the screws coming loose - there was no contact through from the lens to the camera for aperture or focussing. Once I realised what had gone wrong - after I came home, of course - it was an easy fix and no problems since.

Hope that helps,

Graham

Re: Olympus 1.4 converter

Hi Iain an Graham -

Some time ago I had the screw problem which was easy to fix.
When returning home today I checked the base plate screws and on one side all was well - the opposite plate a slight turn on all four didn't fix the focus problem. There was some slight cleaning needed to all contacts but not much to be concerned with.
I have tried the converter on Anne's camera without success.

I would have got much closer had the failure not occurred.


Thanks so much for responding.

Re: Olympus 1.4 converter

It is a shame about the focusing problem as it looks like you had some lovely light. It is still a much better shot than I have managed of our local Kingfishers.

Re: Olympus 1.4 converter

Of course, you didn't push the focus ring back on the lens, did you?

As my 300mm + 1.4 are almost permanently on my OM1ii, that prompts to ask is it just autofocus not working when using the TC, or manual focus or both. If one still works it might help avoid panicking if a similar situation were to arise

Off to check my screws ...


EDIT: And when moving the focus clutch ring to and from manual, did it change the focus setting focusl in the SCP, or was it not communicating back to the camera?
