Omega D2 cone question

[ari velazco]

Hi everyone. I've recently purchased this enlarger with different sizes of cones, from a flat one to a tall one. When should I use one? I have lenses from a 50mm to a 135mm. Thank you very much.

The D2 has a relatively short bellows. So each different focal length lens uses a different cone, in order to achieve the correct focus for enlargement. For example, a 50mm lens uses a flat panel, a 150mm lens uses the longest cone. You'll also need the round adapter plate (these are all the same) that the lens attaches to, and this fits to the cone with two screws. You can find more detail at classic-enlargers.com.

Thanks Mark. Now it makes sense.

The 135mm lens uses the shorter cone, 2 1/2" I think. The longer cone, 4 1/4" or something like that is for the 150mm lens. A 50mm-105mm uses the flat board. In addition to the different cones, there are also different size condensers for each range of lenses or there is also a variable condenser head with a moveable third lens.
