R-D1 & Hacked Industar-69

[Mr_Flibble]

Got this lens a week ago, and I finally got round to adjusting the focus for. I consulted the local lens guru Brian "Mad Gearhead" Sweeney and read through Hamish Gil's tutorial. I decided to go with Brian's method of cutting down the top of the focusing ring on the lens mount.

It took about an hour of trial and error with a Dremel tool. Around the third attempt I had filed down enough of the ring on the lens mount. So I cleaned everything up again, re-lubed the lens helical with some military grade rifle grease and assembled the whole thing.
Then I went for a walk, R-D1 dangling from my neck

Came across this oldtimer. I think I'll run take my jeep for a run today too, if I can get it started.

I found that setting the lens to f/8, focus at about 4 meters and leaving the camera on AE turns your R-D1 into a point-and-shoot camera. 😉

Except for a little bit of vignetting the I-69 behaves pretty well.
The 28mm frame-lines of the R-D1 of course do not correspond with the lens and focus distance, which takes a little getting used to.

I have one too, I modified it with the Hamish Gil's method.
Would you please share details about the Brian's method?
Could you post pictures?
How much thickness did you cut down?
Thanks for sharing.

I wanted to take pictures of the work in progress, but that's kind of annoying when you need the same camera to test if the I-69 finally goes to infinity. 😉

This is Brian's method from another post:

The Focus ring comes off with three set screws. There is a raised metal ring in the aluminum mount that stops the helical from going to far in. I filed off about 1/2 of the thickness of that ring so the helical would keep on going. Used a through-the-lens viewer to get infinity- then put the focus ring back on. The only trick is to space the ring out a little bit so that the focus range goes from infinity to near, and does not get caught on the stop-pins. I just backed the ring out a few millimeters and tightened the screws. We're looking at 30 minutes of filing and hacking here.

I used a dremel to file off about 1mm of the inner raised ring on the mount and the stop pins in this picture

I went for Brian's method, because it was easier to file this part with the dremel. I think if I had tried it on the helical, I would have damaged quite a bit of it.


p.s. Couldn't get the jeep to start 🙁

It looks really good!

I did the I-69 for a Leica M8 user, and it covered the frame as well. It looks really good on the RD-1.

Thanks for the quote!

Now I've mount the industar-69 on a LTM > M43 adaptor to make tests :

It's interesting too and the look is great.

 

[Mr_Flibble]

Looks pretty sweet to me too. I guess an SLR would have made it easier to collimate the lens. Unfortunately I only have an LTM-to-M adapter, but no M-mount SLRs

I thought I didn't have a lenscap for it, but it turns out I had an old RICOH cap in my bits-box that seems to fit it quite well.

Took this one a couple of hours ago. Easter Dinner at my Sister's place. Slightly cropped.

And finally got the jeep to start today,

Here it's parked at the momument at the Kapelsche Veer. It was the site of a fierce battle during the December 1944 and January 1945.
