Do you have a question about the Panasonic Lumix H-ES12060 and is the answer not in the manual?

This document provides a comprehensive service training manual for the Panasonic LUMIX DG VARIO-ELMARIT 12-60 mm/F2.8-4.0 ASPH./POWER O.I.S. interchangeable lens for digital cameras, model H-ES12060. It covers technical information for service personnel, including specifications, exploded views, replacement parts, service fixtures and tools, maintenance procedures, disassembly and assembly instructions, and adjustment procedures.

Function Description:

The LUMIX DG VARIO-ELMARIT 12-60 mm/F2.8-4.0 ASPH./POWER O.I.S. is an interchangeable lens designed for digital cameras, specifically for the Micro Four Thirds Mount system. It features a versatile zoom range suitable for various photographic situations, from wide-angle to telephoto. The lens incorporates POWER O.I.S. (Optical Image Stabilizer) to help reduce blur caused by camera shake, enhancing image sharpness, especially in low-light conditions or when shooting handheld. The "ASPH." designation indicates the use of aspherical lenses, which help to correct spherical aberrations and distortion, contributing to high image quality across the entire zoom range. The "ELMARIT" branding, associated with Leica, suggests a high-quality optical design with a relatively fast maximum aperture. The lens also includes a dust-proof and splash-proof design, making it suitable for use in challenging outdoor environments.

Important Technical Specifications:

Focal Length: 12 mm to 60 mm (35 mm film camera equivalent: 24 mm to 120 mm). This provides a versatile 5x zoom ratio.
Aperture Type: 9 diaphragm blades, forming a circular aperture diaphragm, which contributes to smooth and attractive bokeh (background blur).
Maximum Aperture: F2.8 (Wide) to F4.0 (Tele). This relatively fast aperture allows for good performance in low light and shallow depth of field control.
Minimum Aperture Value: F22.
Lens Construction: 14 elements in 12 groups, including 4 aspherical lenses and 2 ED (Extra-low Dispersion) lenses. This complex optical design aims to minimize chromatic aberration and distortion while maximizing sharpness.
Nano Surface Coating: Yes. This coating helps to reduce ghosting and flare, improving image clarity and contrast.
In Focus Distance: 0.20 m (0.66 feet) to ∞ (infinity) at the wide end, and 0.24 m (0.79 feet) to ∞ at the telephoto end (measured from the focus distance reference line).
Maximum Image Magnification: 0.3x (35 mm film camera equivalent: 0.6x).
Optical Image Stabiliser (O.I.S.): Available.
[O.I.S.] switch: Available (Switching ON/OFF).
[AF/MF] switch: Available (Switching AF/MF).
Mount: Micro Four Thirds Mount.
Angle of View: 84° (Wide) to 20° (Tele).
Filter Diameter: 62 mm.
Max. Diameter: Approx. 68.4 mm (2.7 inch).
Overall Length: Approx. 86 mm (3.4 inch) (from the tip of the lens to the base side of the lens mount).
Mass (Weight): Approx. 320 g (0.70 lb), making it a relatively lightweight lens for its capabilities.
Operating Temperature: -10 °C to 40 °C (14 °F to 104 °F).
Dust-proof and Splash-proof: Available.

Usage Features:

The lens is designed for use with Micro Four Thirds digital cameras. Its wide to telephoto zoom range makes it suitable for a variety of photography genres, including landscapes, portraits, travel, and everyday shooting. The fast maximum aperture allows for creative control over depth of field and good performance in challenging lighting conditions. The built-in Optical Image Stabilizer (O.I.S.) is a significant advantage for handheld shooting, especially at longer focal lengths or slower shutter speeds, helping to produce sharper images. The AF/MF switch provides quick toggling between autofocus and manual focus, offering flexibility depending on the shooting situation. The dust-proof and splash-proof construction ensures reliability in various weather conditions, expanding its usability for outdoor photographers.

Maintenance Features:

The manual emphasizes the importance of a clean environment for repair and maintenance, recommending work in a clean room or clean box (at least class 10,000).

Dust/Dirt on outer casing: Can be cleaned with a soft cleaning brush and a dry fuzz-free cloth.
Dust/Dirt on lens glasses (outside surface): Should be gently blown off with a blower, then wiped with a lens cleaning kit (VFK1900BK) if necessary. The cleaning instruction specifies wiping from the center outwards in a circular motion.
Dust/Dirt on lens glasses (inside surface): Requires disassembly and must be performed in a clean environment.
Disassembly and Assembly: Detailed flow charts and step-by-step procedures are provided for disassembling and assembling various units of the lens, including the Decoring Unit, Filter Ring, Shading Frame, L Mount Unit, Dustproof Rubber, Rear Frame Unit, Lens P.C.B. Unit, L Mount Contact Unit, Rear Frame Earth Spring, Zoom Drive Pin, Ring Mount Base Unit, Zoom Ring Unit, Wave Washer, 1st Lens Holder Unit, 2nd Lens Frame Unit, 2nd Lens Shading Plate, 3rd Lens Frame2 Unit, 5th Lens Frame Unit, and Cam Barrel Unit. Specific screw types, sizes, and torque values are provided for assembly.
Adjustment: A matrix chart indicates necessary adjustments (Electrical Adjustment and 1st Lens Frame Adjustment) when specific parts are replaced. A flow chart outlines the adjustment process, which involves initial electrical adjustment, 1st lens frame adjustment, confirmation using an RP chart, and gluing of adjustment pins.
- 1st Lens Frame Adjustment: Involves rotating adjustment pins using a Torx driver (RFKZ0609) while visually checking the Modulation Transfer Frequency (MTF) at TELE and WIDE settings. The MTF is checked at the center and four corners, with specific resolution specs for concentric circles and radiation (lp/mm).
- Electrical Adjustment: Performed using a PC with adjustment software.
- Visual Checking (RP Chart): Involves mounting the repaired lens on a master camera, setting specific camera parameters, and taking photos of RP charts (L-size and M-size) to visually check for focus, resolution, and balance across the image.
Service Fixture & Tools: A list of required tools includes a Lens Cleaning Kit, Torque Driver, Torx Driver, Blower, Collimeter, Reference Camera/Lens, Lens Projector for Adjustment, Lens Adaptor, Projector Chart, Lens Control Adaptor, General-Purpose Camera Body, Hand Miller, RP Chart L-Size, RP Chart M-Size, Tripod, PC, SD Card, and Dark Room. A clean hood (RFKZ0429) is also recommended.
Important Notice: Emphasizes the need for close attention during repair due to the lens's sensitivity to dust, soil, sand, and fingerprints. It also states that the repair method described is not identical to the factory production line and stresses adherence to the manual's instructions, especially regarding disassembly/assembly order, screw torque, and screw order.
