How do I mount lenses on Omega D6 turret board?

There are a few different mounting plates depending on the focal length of the lens you are mounting. The basic plate is a 421-055 which has no offset for a 50-80mm lens. The 421-132 is used with a 135mm. There are other plates, but I dont have a list handy. Also there are a couple of models that do not require a ring nut to secure the lens, you just screw the lens in. Hope that helped.

I was where you were at when I got my D5, turret, one lens, no flange plates, and other lenses to mount. I used the lens flange I had as a template to make others out of thin aluminum plate, and then put the lens in and made a thread holding ring out of fimo modelling clay rolled into a ring and them pressed into the threads that were though the plate. Before I could get it painted I found the real deal in a lot of bits I bought off craigslist, but the home made solution worked fine for the week that I used it. When fimo is not strong enough on its own, I spead the outside of whatever I have molded from clay with hot glue. They are not pretty items, but are functional.

 

As you are buying lenses, try to get ones that have their "jam nut",

If not, they are available. http://www.shop.com/lens+jam+nut?g=1&t=2&p=259444460&k=24

Lenses and mounting plates, nuts, etc are all readily available. Ebay is a good source for this sort of thing. As someone already said, there are lens plates for the Omega that are already threaded, and you won't need a nut if you get that sort of plate. The Nikkors are generally 39mm, which is oftern called "leica mount". This is close to being a standard for enlarger lenses, but it is not universal. But a 50, 80 or 105 will most likely be 39mm mount. Larger lenses may have a larger mount.

Flat plates are available for mounting single lenses. However, on the turret, you may need plates that allow the lens to be offset a bit so that the back of the lens will clear when the turret is rotated. This is hard to describe without pictures, but since you have the turret, it should reveal itself to you.

This should guide you to the lens/mounting plate combo you want.
As mentioned the size of the mounting hole is variable but standardized. as well the thickness/length of the lens requires mounting plates of different thickness to slide in.

 

I am not sure what you mean by this but if you don't use the turret at all you will need a single lens slide in mount thingee in addition to the lens and the plate.

 

Not sure. Actually, it references the 50mm f2.8N specifically. There are other Nikkor 50mm lenses and there may be something to that. I don't believe it is eliminating all other Nikkor focal lengths, especialy since the chart lists the proper mounting plates for all the rest for the turret.

On my turret, I had mounted (all EL Nikkors) a 63mm, an 80mm and the 105mm.

One option would be to get the slide in lens plate and a threaded mount. You could then put on any one lens at a time. To help finance this, the turret could be sold. They usually go for pretty good money. Just a thought.

 

Very carefully.

 

There are differences in the protrusion of the lens above the L39 mounting threads, some are below the threads, some are flush and other lenses protrude above the mounting threads. A lens that protrudes above the threads just might have something jam in the turret mount.

 

Don't be so quick to rid yourself of the turret, you'll find it's quite useful once you start shooting multiple formats.
