50mm is normal for 35mm. 80 is normal for 6x6. 135-150 is normal for 4x5. You need a cone to move the enlarging lens for 4x5 farther away from the film. Looks like:

(that one is over 4 inches - there are shorter ones that will be fine for the 135mm lens)
Why is this extension needed for 135mm? The focus bellows extend more than this.
The door swing up and the top condenser can be moved for 50 to 80mm, middle position for 100 to 135 lens and removed for 150 and longer.
Pretty sure the cone would be for 4x5 size lenses. 35mm lens is much closer to the film plane.
The OP photo shows the variable condenser head. If it is like the variable condenser for the D5, no condenser is needed for 4x5. A 150mm lens is, though, and of course a 4x5 (preferrably glass) carrier.

I just dug out my variable condenser and put it in the slot for 135 (since I have a 135mm lens on the enlarger right now) and I can't see anything that it's doing. I assume it should impact the brightness in the corners - that that is where it would be apparent - but I can't see any difference whether it's in or not.
Here is a link to the manual.
any recommendations for 4x5negative carriers? I think it should be a glass carrier for 4x5.
found another manual with accessories:
I think an older model
I have a 135mm that will cover 4X5, but prefer either a 150 or my Wollensake 162, 150s are the most common. The D series can use a number of different boards with different size plates, it is the smaller plate that is attached to the lens board. I have different plates for many different size lens. 39mm is common.
yes, noted the condenser placement inside. Is there a filter tray for Omega D and would you place it in one of these spots?
