Minimizing enlarger upgrade cost

[yeknom02]

Hi everyone,

Being a mostly 35mm and 120 photographer until this point, I have a recurring itch to dive into 4x5, beyond just trying it for a weekend every few months. I've only made a handful of images by now since my only option at this point is to scan the negatives.

I've got a Beseler 23C (series II, the blue one), and I've got it outfitted with the multigrade filters, the right negative carriers, lens boards, and lenses for both of my current formats... Did Beseler make a 4x5 enlarger that will take these 23C accessories so I can start to shop for an enlarger that can minimize my upgrade costs?

And before you suggest it, I can't have more than one enlarger at a time. The amount of available space makes any more unreasonable.

Somone else might be better able to answer your compatibility question between Beseler 23 and 45 enlargers.

However, given the current market for darkroom equipment particularly big enlargers, I wonder if you question might be moot. You might find the cost of a used but complete Beseler 45MX or Omega D5 enlarger relatively low.

I had a nice Beseler 45MX with condenser head, cold light head, 35mm, 6x6, and 4x5carriers, Beseler drop table, and an 80mm Rodagon and 135mm Ysaron enlarging that I sold relatively cheaply to make room for another acquisition.

Have a look at the local market (Craigslist, Kijiji, etc.) if there is one, to find out.

Good luck!!

You can convert a 23C to a 4x5 with a few simple steps -

I just did his conversion of a 23C and am quite happy with the results.

That link does not work for me can someone point me on how to convert my23c into a 4x5

I was thinking of that link myself, but couldn't remember where I'd seen it. Beseler also made an adapter (part #8273) which allows using a Beseler 4x5 light source on the 23C enlarger. I'm not positive of its suitability once the modifications mentioned in the link are done. But it may be a simpler way to mount a 4x5 light source if building an LED head is not attractive.

The link to the modification indicates that you will lose 35mm capability. Perhaps with some further ingenuity, that can be overcome. Or perhaps R Mann can shed some insight on it.

If space is an issue, a 4x5 enlarger will make it more of an issue. And even though used enlarger prices are low, unless you can find one locally, shipping costs will be high - if the seller is even willing to ship at all.

Going from a 23c to a 45m requires larger negative carriers and filters, but both use the same lensboard and lenses.

More on the 23C conversion to 45 -

The 35mm "problem" occurs because when you combine the top and bottom bellows in the conversion, you can't compress them enough to focus a 50mm lens. But, if you use a longer lens (80mm) and you will have no problem with a 35mm negative - just less enlargement. As the link states - Omega 4x5 negative holders fit just fine, and are easy to find used. Filters are not a problem, either use a below the lens set, or include a filter slot in the head - which is what I did to fit a set of 6x6 Ilford VC filters.

Total conversion cost including the new LED Head and a set of Omega negative holders was less than $175.

When I get a chance I will post a few photos, but they are really just a repeat of the photos in the link, except for the light source. I used an LED set up that is a little different.

I'm guessing this will be ok... absolutely everything I enlarge goes onto 8x10 paper. I actually toyed with the idea of trying to design a "fixed" enlarger that would do a 2x (4x?) magnification from 4x5 film to an 8x10 since it's the only paper I use. I imagined that since I wouldn't have to adjust height (maybe just a fine-tuning adjustment for focus) I could make it pretty lightweight. Unfortunately, I don't know much about optics and the idea never evolved.

...Unless someone else would like to chime in with some support for this idea...?

Get a 60mm WA and it covers up to 67cm while almost giving the same print size from 35mm.
