49mm UV Protection Filter

The Haoge 49mm Ultra Slim MC UV Protection Filter fits any lens with a 49mm thread. It uses B270 optical glass with double-sided multi-coated nano layers that deliver over 99.5% light transmission. The filter shields the front element from scratches, dust, moisture and fingerprints while adding negligible optical impact.

49mm Thread Compatibility Limits

The filter mounts directly on standard 49mm threads found on lenses such as the Sony 40mm f/2.5 G or Sony 50mm f/2.5 G. Fuji X100 series cameras require the separate Haoge adapter ring ID LAR-X52W or hood ID LH-X54W before this 49mm filter can be installed. The Leica Q3 43 is explicitly excluded because the filter would interfere with its macro function.

Slim Frame Prevents Vignetting

The ultra-slim aluminium alloy frame with double-thread design avoids vignetting on wide-angle lenses. Matte coating and laser-engraved markings reduce internal reflections. This low-profile construction is the decisive specification for buyers who need full corner-to-corner coverage on 49mm threaded optics.

Questions about this item

Which 49mm version should I choose for a Fuji X100VI?

The filter itself is 49mm, but Fuji X100 series cameras need the Haoge adapter ring LAR-X52W or hood LH-X54W first; without one the filter cannot be mounted.

What does the 99.5% light transmission figure mean when the filter is on the lens?

Over 99.5% of visible light passes through the B270 glass, so exposure and colour balance are virtually unchanged while UV haze is blocked.

How does the double-thread design affect stacking or lens caps?

The frame has front and rear threads, letting you keep a 49mm cap on the filter or stack another 49mm filter without vignetting on most lenses.
