Fotodiox repair, service, and parts

Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.

2 Most Seen Failures:

Loose or Wobbly Lens Mount

Lens adapters can develop excessive rotational or lateral play between the lens, adapter, and camera body as mounting flanges lose tension or retaining screws loosen. The movement can interfere with precise focusing and, in severe cases, optical alignment.

Autofocus Slow, Hunting, or Nonfunctional

Fusion Smart AF adapters commonly exhibit slow autofocus, repeated hunting, inaccurate focus, or complete loss of autofocus with certain lenses. Older, third-party, and long-telephoto lenses appear especially susceptible to compatibility problems.

Camera Freezing or Adapter Lockups

Electronic Fusion adapters can cause the attached camera to freeze, become unresponsive, or require a power cycle or battery removal. Lockups are particularly associated with certain video modes, lens combinations, and firmware compatibility issues.

Electronic Aperture Control Failure

Smart adapters may intermittently fail to control the lens diaphragm, produce aperture fluctuations, or cause visible exposure flashes when changing f-stops. Some reports describe aperture mechanisms becoming unresponsive or remaining at an incorrect opening.

Incorrect Infinity Focus or Focus Calibration

Mechanical and optical adapters can be manufactured slightly outside the required flange-distance tolerance, preventing lenses from reaching true infinity focus or shifting their indicated focusing distances. Even small dimensional errors in an adapter can noticeably affect focus calibration.

Lens or Adapter Binding in Mount

Some Fotodiox adapters fit excessively tightly or have release mechanisms that bind, making lenses difficult or impossible to remove normally. Manufacturing tolerances, retaining hardware, or misaligned locking components can cause the lens or adapter to become stuck.

ND Element Contamination, Haze, or Flare

Vizelex and ND Throttle adapters can develop image degradation from contaminated, oily, streaked, or optically problematic internal ND elements. The resulting symptoms include haze, flare, faded areas, reduced contrast, and uneven image sharpness.

Aperture or ND Control Ring Slipping or Jamming

Mechanical control rings on ND Throttle and aperture-control adapters can loosen, slip from the selected setting, become imprecise, or jam. Wear in the detent, spring, bearing, or ring-retention mechanism is a recurring cause.

Filter Holder Slippage or Loosening

WonderPana filter systems can allow filters to move or fall when the retaining bolts or grooves do not provide sufficient tension. The system's rotating components can also loosen threaded filters during adjustment, increasing the risk of accidental filter release.

  1. 1 Repairs are performed on a best-effort basis. Acme Revival utilizes a network of sophisticated technicians and engineers with diverse service offerings; despite this, factors that influence the repair outcome may ultimately prove unsuccessful. Acme Revival makes no claim that it can, guarantee a repair before your device is sent in for diagnostic evaluation; even then, repair and diagnostic work are not mutually exclusive. Despite well-intentioned quoting, repairs may still prove unsuccessful.
