Title: 105/1.8 Repair?
Post by: Tristin on April 30, 2019, 01:06:38

My beloved 105/1.8 took a fall without it's rear cap and the result is as shown.  The focus ring can't rotate outside of ~.9-1.3m and the aperature is stuck at 5.6.  It won't mount so I have no idea if the impact jostled the elements, but a simple flashlight examination shows no issues.  What do you guys think, worth repairing?  I hope so!  If anyone is so inclined, I would be more than happy to pay for the job.  This is an excellent sample, and would like to keep it instead of getting a new one.

Welcome back, Tristin.  The only regret is that you returned with the sad news.  Wish your problem is solved in any way pleasing to you.

I suggest you remove the black stray-light baffle first, then see if that's the reason the lens workings are jammed. The baffle is kept in place by three small screws, plus probably also the stop screw (even smaller). You need to use JIS screw drivers otherwise there is a danger of stripping the screw heads.

If the lens once free of the baffle works, the remaining task is to reshape the baffle into a round form again. Or try shooting without until a replacement is found.

I removed the baffle and tried my best to reshape it, but I do not see success happening.  Then I accidentally wrecked the tiny spring for the aperature lever.  So, looks like a replacement is in order.  I suppose on the bright side I have nearly an entire replacement lens for the future.

Btw, thanks for the welcome back Akira.  Been on a creative hiatus for a few years now, looking to dust it off!

I can arrange that, it would be great for a write up to be done on the 105/1.8 and you are the man for the job!  Pm'd.
