Sony a-5056-308-a First Group Assembly Lens

Product Description

The SONY a-5056-308-a is a first group lens assembly designed as an internal optical component for compatible Sony camera lenses. This part serves as the front optical group within the lens barrel, housing the primary glass elements responsible for initial light gathering and image formation. It is a factory-replacement assembly intended for bench-level repair by qualified camera repair technicians or Sony-authorized service centers. The reference designation SELP16502 in the supplier data suggests association with Sony E-mount zoom lens assemblies. Proper installation requires precision optical alignment and clean-room handling practices.

This first group assembly is used in professional and consumer camera lens repair scenarios where the front optical group has sustained damage, delamination, fungal contamination, or physical impact. It is not a field-serviceable part and is intended for depot-level or bench-level disassembly and reassembly by technicians with experience in optical component service. Typical applications include lens refurbishment and optical path restoration in Sony mirrorless or interchangeable-lens camera systems.
