Are enlarger lenses interchangeable?

[Eric De Santiago]

I’m planning on selling my Vivitar 356, and I want to know if I should sell it with the lenses (50mm f/3.5 and a 75mm f/3.5), or if I should keep the lenses for when I buy a 6x7cm enlarger. Also, any tips on selling an enlarger?

If the enlarger accepts interchangeable lens boards, then just about any enlarging lens can be used on any enlarger. Enlarging lens focal length has to do with the negative size and your choice. For example, most folks probably print MF with an 80mm enlarging lens, but I prefer 100mm. I use the more typical 150mm lens for 4x5.

Selling enlargers is tough, unless you have something that people really want. Probably most used enlargers wind up in the landfill.

You not necessarily need a lens board. One may just screw out the lens and screw in another. On the assumption that the thread is the same and that the position of the lens board is apt for the focal lenght of the lens if that focal length is at the shorter side.

Some autofocus enlarger make it difficult to mount other then the proprietary lenses.

As the lenses are not high spec, I would sell them with the enlarger.
The last enlarger i had like this I gave it away to a school teaching analog photography, One of the students gave a donation to the school for it
.........It was no use to me as I have 3 High end Durst Enlargers but it was to good to just bin it
.....it has a new home and another student can print from film.

Craigslist or local sales resources work better than something like eBay, because shipping an enlarger is prohibitive.
If there are any used goods "swap" meets that you would be willing to rent a table/place at, they can be a good place to try - consider supporting that effort with a Craigslist ad indicating that the enlarger will be at the meet.

Sell your entry level lenses with your entry level enlarger. Your cheap 75mm will not "cover" 6x7 anyway, for that you need a good 80mm (and not all 80mm lenses are suitable either) or 90mm lens.
