KEY TAKEAWAYS

• How to check: Inspect the leaf shutter mounted in your lens and test at each speed setting

• What’s acceptable used: Look for consistent operation across all speeds with no oil or debris on blades

The Deardorff 5×7 folding view camera shutter count works differently than modern digital cameras because it uses external leaf shutters mounted in each lens. Unlike DSLRs with body-mounted shutters, checking your camera’s condition means inspecting the mechanical shutters in your lenses.

How to Check Shutter Count on the Deardorff 5×7 Folding View Camera

The Deardorff 5×7 folding view camera shutter count isn’t a single number stored in the camera body. Large format cameras like the Deardorff use leaf shutters built into each lens (Copal, Compur, or Ilex), so you need to check each lens individually.

Here’s how to assess your shutter’s condition:

1. Step 1: Remove the lens from your Deardorff and inspect the leaf shutter mechanism. Look at the shutter blades through both the front and rear elements.
2. Step 2: Fire the shutter at each marked speed setting (1 second through 1/400th or 1/500th depending on your shutter). Listen carefully for consistent operation – each speed should sound distinct and operate smoothly.
3. Step 3: Check the shutter blades for oil residue or debris. Oil on the blades appears as rainbow-colored streaks and will cause sluggish operation. Dust or debris can prevent full closure.
4. Step 4: For precise measurement, test with a shutter speed tester. This electronic device measures actual vs marked speeds. Acceptable variance is typically +/- 1/3 stop.

Unlike digital cameras that track every exposure, mechanical leaf shutters don’t record their usage. The Deardorff 5×7 folding view camera shutter count assessment relies on physical inspection and performance testing rather than a digital readout.

What the Shutter Count Means for the Deardorff 5×7 Folding View Camera

Deardorff has not published an official shutter life rating for the 5×7 Folding View Camera. This is standard for large format cameras since the shutters are in the lenses, not the camera body. Each lens manufacturer (Copal, Compur, Ilex) had different specifications for their shutters.

Similar mechanical leaf shutters from this era typically last 100,000-300,000+ actuations when properly maintained. However, age and storage conditions matter more than total actuations for these vintage shutters. A 50-year-old shutter with 10,000 actuations stored in humid conditions may perform worse than one with 50,000 actuations kept in proper storage.

When evaluating a Deardorff 5×7 folding view camera shutter count isn’t about a specific number – it’s about current performance:

• Excellent condition: All speeds accurate within 1/3 stop, no oil on blades, smooth operation
• Good condition: Minor speed variations (1/2 stop), clean blades, occasional hesitation at slow speeds
• Needs service: Speeds off by 1+ stop, visible oil or debris, inconsistent operation

How Shutter Count Affects Used Deardorff 5×7 Folding View Camera Pricing

Since the Deardorff 5×7 folding view camera shutter count can’t be numerically determined, pricing depends on overall condition and included lenses. A camera with recently serviced shutters commands premium pricing regardless of age.

Shutter service typically costs $150-300 per lens. Factor this into your buying decision – a lower-priced camera with sluggish shutters may cost more after necessary repairs.

Selling your Deardorff 5×7 Folding View Camera? Knowing the shutter count helps you price it right. Document each lens’s shutter performance with test results or recent service records to justify your asking price.

Remember that collectors often value original unserviced shutters if they still function properly. Some buyers prefer knowing the full service history rather than wondering what work was done. Visit the Deardorff 5×7 Folding View Camera GearMaster page for current market pricing trends.

FAQ

Can leaf shutters in Deardorff lenses be serviced?

Yes, qualified technicians can clean, lubricate, and adjust most Copal, Compur, and Ilex shutters. Service extends shutter life significantly and restores accuracy. Costs range from $150-300 depending on shutter type and condition.

How do I test shutter speeds without electronic equipment?

Use the “TV test” for rough accuracy. Set your shutter to 1/60th (or 1/50th) and photograph a CRT television or monitor. The number of scan lines visible indicates accuracy – you should see one complete scan at these speeds.

Does the Deardorff 5×7 folding view camera shutter count include both front and rear shutter use?

The Deardorff body has no shutter – only the lenses contain shutters. Each lens accumulates its own wear independently. When buying used, check every lens you plan to use, not just the one mounted on the camera.
