I.7 con not working.

[mark richards]

for some reason this wont work anymore, any ideas what it could be?.seems like its not opening the aperture enough on the lens,its very dark
it still auto focuses, if held towards a light you can make out the bulb, probable only only used this a dozen times, so bloody p***ed off.

Are you sure it's not your lens or have you changed bodies recently , personally I would give ALL the contacts I.e body,lens and t.c a very thorough cleaning ,de-greasing

+1 to this.......apparent miscommunication is often due to poor connection/connectivity.

Nick-crap 1.7 tc

Try cleaning all the contacts as ready suggested by Jeff there is very little to go wrong with them and if images are dark it could well be a lens fault!
Do you always mount converter first to the body then attach lens ?

What camera are you using this with?
What lens?
What model 1.7 is it?
Have you dropped it?
If you hold this up 'by itself' - no lens or camera attached - can you open the blades ?

 

[Martyn...]

Have you connected it in haste and slightly bent the flat connecting pin on the TC that moves the aperture blades.

I did it something similar on a 1.4TC, I separated the TC from the lens and saw that I had forced some lever where it shouldn't go, put it back together with a bit more care and it worked fine.

couldn't find the two fingers.


I use this with 300 f4 that works fine, its just not opening aperture, I cannot see anything out of place Martyn, will match this up with my 1.4x and see if i can see anything out of place.

I had a similar problem with a 1.7 TC when at Bempton I left it on the body and changed lenses ( trying to keep dust out ) it had slightly bent the aperture prong. Managed to sort it and since then I always put the TC on the lens and then onto the body.

Hope you get it sorted Mark.

Mark might be worth checking the lever on the back of the lens as well.
