yes, it may help if I use a tripod as well I think.
It was a bit of a strain on the arms.

Sigma 135-400mm DG APO with 2x Vivitar Teleconverter.

Well having read this thread I then went back to the Sigma Macro sale and to my suprise found a lot of it missing.
I am presuming this must have something to do with it and to some extent I feel a little responsible because the second post on the thread was deleted by myself, purely because I was interested to see if it could be done and with no malice intended . infact it only said : you have a PM re sigma lens but from thereon everything by me has been left .. unlike the original authors comments.

Anyway, I think the fact that a post can be totally deleted after any time limit is totally wrong, as for alteration, I quite often go back to a post to add more content but I have never changed the meaning of anything I have written and could live with a 30 minute limit if necessary .. but I am not sure it is.
The only thing is that it is going to be nigh on impossible to prove if you go the punishment route unless you have a backup of everything posted here as it is written.

I read that its best to fit the mount wide open, I am lining up the green dots and the lugs click into place.
The actuator on the mount is not operating the one on the lens (or the teleconverter when attached to the 90mm).

The lens itself: if I press the actuator when the aperture ring is halfway, the iris will close half way and if I press it when in A mode it will close all the way and when I release it will open.

It works exactly the same as my 90mm ... just not when I attatch the mount.

It really is doing my head in.

I do have a lot of trouble mounting it properly on the 90mm when I take it off and I tried the mount on a adaptall 2 SP 2x teleconverter which I attached to the 90mm and then had the same problem.

90mm Mount.




70-210mm mount.




2X Teleconverter Mount.




They all look slightly different to me anyway.

Has anyone got the manual that comes with this mount that they could photocopy for me?
I have a 90mm Macro f2/8 72B that came with one on it and works fine but I cannot get it working with my 70-210 SP f3/8 that came this morning.
For some reason it will just not work the aperture lever, therefore the lens is always wide open.
I have spent about 3 hours this morning trying to get it working and decided I had better ask here now before the lens ends up in the TV screen.

Thanks.

Ahh, thats why she goes all funny when I start blowing on the lens and rubbing it down after a day out.

Well it certainly does now, I actually missed the out of the first sentence of my last post.

Still trying to work out how we got from photographic techniqe to paedophile puppet makers.
Talking of which, I have never really noticed before but when we used to go to the park where all the duck are a few months ago everything was fine but since I have taken up photography as a hobby and take my camera even my wife comments about me carrying it around and I do get some very strange looks.

I suppose it's the world we live in today ....

Yes, thats just what I am after thanks.
As for the name change, I asked for it before the weekend, I am having it done on all the forums I use as I wanted it to be the same everywhere and it is the name my flickr account is in

Also, I was bored of being a Sockpuppet, I wanted to be a real boy
