Interesting, thank you Ray. I have indeed learned a lot and am continuing to learn. I will try again now that I understand it's only the centre of...
I haven't quite given up yet but I am approaching that stage now. I spent a couple of hours tweaking the end pins today and whilst I can see focus...
Thank you, Ray. I hadn't considered the fact that identical lenses could have different results. I will fiddle with the end pins until I can get...
Ray, do the eccentric collars only need to be positioned in one of the three orientations shown in your diagram or are they more of a ballpark...
I have the lens part-disassembled so none of the electrics are connected. I have a rubber band holding the focus arm and am manually tweaking the...
Haha, no sorry for the delay. I was struggling a bit with the eccentric collars as they are a little chewed which makes it tricky to tell when...

Well, the good news is I managed to find the other cable, which is marked UK1303 -02. The bad news is one of the screw towers which holds the...
Oh wow that's really useful thank you. It is a minus on the large cable as I assumed it was a dash. I'll have a proper look after work, and I...

Made an attempt at adjusting the eccentric screws on this, I can certainly see a difference in focus when making fine adjustments and I can get a...
Thank you both for going to the trouble of giving your feedback, and replicating the photo using the same lens. It's quite clear the 24-105 should...
I managed to find a decenter test grid and followed the instructions, and the lens appears to be perfectly centered. Following the other advice...
Thanks guys, I just got finished reassembling this lunch time and early indications are that it all works perfectly. Thank you. I don't know if...
Well, not exactly overwhelmed with responses but to draw the issue to a close for anyone else struggling, I managed to get some screws for £10...
