Manually change DNS servers
Most likely your DNS servers are set to “Obtain DNS server address automatically” (by default) my browser wasn’t loading pages fully and all kinds of stuff, that’s when I found this trick. Click the “Use the following DNS server address:” and type in the numbers shown above: 126.96.36.199, 188.8.131.52, then click “OK” no need to restart your computer.
This address is for “OpenDNS”, a company owned by Cisco, there are others, including Google 184.108.40.206 , 220.127.116.11 but the OpenDNS was the fastest I could find.
After completing the service, cleaning, repair, adjustment on the 1936 Leica IIIa, I shot a test roll to see if everything was working as it should. There are a lot of things that can be wrong on an 80 year old camera. A test roll can show if the film is advancing correctly, getting the proper space between images on the negative, shutter speeds are correct, the rangefinder and lens are in good sync so the images come out good and clear. etc…
The first test roll showed that the shutter was at the right speed but on the faster speeds, it was not adjusted correctly. The second or “closing” curtain was catching up with the first curtain part way across the film area.
On this type of camera, there are two curtains that act as the shutter. First the opening curtain starts it’s travel then, depending on the shutter speed you choose, the closing curtain starts it’s travel. On this model, at 1/20 of a second the opening curtain has exposed the entire film area before the closing curtain starts it’s travel. At 1/500, it only gets about 1/8th of an inch before the closing curtain starts it’s travel. They travel together at 1/8″ across the entire film area. No matter what speed you set it, the curtains physically travel at the same speed, (about 1/20th sec.) it’s the size of the opening that determines the shutter speed. At 1/1000 shutter speed, the opening is about 1/16th of an inch, 1/200 about 3/16ths and so on.
So you can see, the curtains have to be adjusted so they travel at the same speed. After the first test roll, I had to take the camera apart again so I could see the shutter at work. (this camera and many others like it doesn’t have the back open to put in the film, you load it from the bottom so you can’t see the shutter working unless you take the outer shell off) I was able to tension the curtains so that the closing curtain wasn’t catching up with the opening curtain.
It’s very rewarding to take an instrument almost 80 years old and repair it and know it’s good for at least another 10-20 years before it will need to be cleaned and adjusted again.
Before giving my Leica IIIa a semi-complete CLA, I want to tackle the slow speeds being sluggish problem. Thanks to the Internet, I found a few sites that explained how truly easy it is. I mean, anybody can do this task and perhaps bring their 75-80 year old camera back to it’s former glory.
Two screws to get started is all it takes. The hardest part is putting it back in and that just takes some dexterity. This method is possible without a complete removal of the body shell as is needed for the newer IIIb. IIIc, IIIf, IIIg, but if you are planing a shell removal for whatever reason, CLA, investigation of a problem or the like, then by all means, wait until then, it would just be easier to put it back in but taking it out makes no difference.
