Yes — based on the information shared, H-X025 and H-X025E are the same lens. The extra letter is a regional suffix used for different markets, not a different optical design or a newer/older version. Panasonic support reportedly confirmed that the suffix identifies the country/region where the product is sold. In practice, lenses with these regional suffixes are typically identical aside from packaging, documentation, warranty region, or local certification markings. So if the lens is the Panasonic Leica DG Summilux 25mm f/1.4 ASPH, receiving a box marked H-X025 instead of H-X025E does not by itself mean you were sent the wrong lens.
