There's no single right first enlarger. There's the one that takes your biggest negative, comes with the parts to print it and fits the room you have. Get those three right and the rest is detail. Here's how we'd narrow it down, starting with the film you shoot and ending with the extras you'll need on the first night.
Buy for the biggest negative you shoot
Enlargers are sorted by the largest negative they take. A 35mm machine tops out at a 24x36 mm frame. A medium-format one takes roll film from 6x4.5 up to 6x9 cm. A large-format one takes 4x5-inch sheets or bigger. Going up a size doesn't lock you out of the small stuff, because bigger machines print smaller negatives with the right carrier, lens and condenser or mixing box. Beseler's 4x5 carriers include 35mm, 6x4.5 and 6x6 versions, and the LPL and Omega 4x5 range runs from 35mm and Xpan up to 4x5.
If you shoot 35mm and might pick up a Rolleiflex one day, a medium-format enlarger saves you buying twice. Take the Beseler 23C. Its carriers run from 110 and 35mm through 6x4.5 and 6x6, and Beseler made glass carriers up to 6x9. The same carriers fit every 23C, so a later 23C III takes them too. If you'll only ever shoot 35mm and space is tight, a 35mm machine is smaller. KHB, for example, lists LPL's 3301D as a 35mm condenser enlarger that doubles as a copy stand.
Pick a light source
The head decides how your prints look and what paper control you get. Our guide to condenser, diffusion and color heads goes deep, but the short version comes from Omega's own manual. A condenser prints about one paper grade harder than a diffusion head from the same negative, and sharpness is the same because the lens sets it. Condensers show dust, scratches and grain more. Diffusion heads hide them.
Variable-contrast paper lets you change grade without changing boxes, and condenser, diffusion and color heads can all print it. A condenser head does it with filters. KHB lists filter drawers for Omega's B-22, C700 and B600, a filter holder for the Beseler 23C, and a filter tray on the LPL 7700 that takes 100 mm squares. Ilford sells Multigrade filter sets in 3-inch and 6-inch squares for drawers, and a kit that hangs under the lens. A dichroic color head skips the filters. You dial magenta for more contrast and yellow for less. LPL's VCCE heads let you dial the grade itself and keep the exposure the same.
Think about the room
Size creeps up fast. LPL's 7700 medium-format machines weigh about 16 kg, and KHB says the XL column throws 16x20-inch prints on the baseboard. LPL's 7452L 4x5 stands on a 135 cm column with a 60 by 80 cm baseboard and weighs about 31 kg. Some heads turn around for bigger prints. The LPL 7700 head rotates for wall projection, and Omega's C760 manual mentions a reversible girder for floor projection of mural-size prints. If you're short on headroom, wall-mount kits were made for some, including LPL's 4x5.
If it's a color head, the lamp matters as much as the size. Several halogen lamps for Beseler, LPL and Omega color heads were listed out of stock at KHB when we checked in October 2026, so buy one with a lamp that lights.
Heavy machines also mean a trip to collect one. Our guide to moving a big enlarger covers how to take one apart.
Pick a model with parts around
Carriers, lens boards, bellows, lamps and mixing boxes are all model-specific, so a common model is easier to complete. KHB is a factory-authorized service shop for LPL, Omega, Beseler and De Vere, and its lists of new and used carriers, boards and parts are full of the Beseler 23C and 4x5 machines, the Omega B and D series, and LPL's 6700, 7700 and 4x5 enlargers. It still lists new LPL 7700-series and 4x5 enlargers too. Browse Beseler, Omega and LPL to see what's for sale now, or start with a model like the Omega D2 or the LPL 7700, both well covered in KHB's parts lists.
Brand also decides the lens board. Beseler's 4x4-inch boards fit both the 23C and the 45MX and other 4x5 models, so lenses move up with you. Omega's D2 uses lens discs in flat mounts or cones, and LPL ships a 39mm thread board as standard.
Watch for rebadges, because they open up the parts hunt. KHB's LPL guide says the LPL 7452L 4x5 was first sold in the USA as the Saunders/LPL 4550XLG and is now sold as the Omega/LPL 4550XLG, and the LPL 4x5 carriers it lists fit both LPL and Omega 4x5 machines. A Saunders-badged LPL takes LPL parts.
What else you'll need
A lens, unless one comes with it. The rule of thumb from the largeformatphotography.info darkroom primer is a focal length about equal to the negative's diagonal, or the corners fall off. In practice that's a 50mm for 35mm, 75 or 80mm for 6x6, 80 to 90mm for 6x7, 100 to 105mm for 6x9, and 135 or 150mm for 4x5. Wikipedia's enlarger article adds that enlarging lenses are sharpest about three stops down from wide open.
A timer. A GraLab 300, the classic dial timer, switches the enlarger and the safelight, has a focus switch and runs from 1 second to 60 minutes. If you get serious, an f-stop timer changes exposure in fractions of a stop, which makes test strips even. RH Designs, which makes the StopClock, credits Gene Nocon's 1987 book Photographic Printing with popularizing the idea.
A focusing aid. Grain focusers from Paterson, Peak and others magnify a small patch of the projected image so you can focus on the grain, and Paterson makes one meant for big enlargements.
A simple way to decide
- Shoot only 35mm and short on space? A 35mm machine with a 50mm lens.
- Shoot 35mm and 120, or might later? A medium-format machine with carriers for both.
- Shoot 4x5, or want one machine for everything? A 4x5, if you can collect it.
- Dusty or grainy negatives? Lean toward diffusion or a color head.
- Want punchier prints with filters? A condenser head and a filter set.
