Tiffen 49SFX12 49mm Soft/FX 1/2 Filter

The Tiffen 49SFX12 is a 49mm screw-in diffusion filter from Tiffen's Soft/FX line, designed to produce a gentle softening effect at 1/2 density. Unlike a standard soft-focus filter that blurs the entire image, the Soft/FX works by selectively smoothing fine details — skin texture, small wrinkles, and minor blemishes — while leaving larger structures like eyes, hair, and facial contours sharp and well-defined. This makes it a popular choice for portrait, beauty, and interview work where a flattering, polished look is desired without the artificial appearance of heavy diffusion.

The filter is manufactured using Tiffen's ColorCore technology, a process in which the diffusion material is laminated between two layers of optical glass. This construction ensures consistent effect across the entire surface, maintains accurate color transmission, and provides the durability expected from professional-grade filters. The 49mm size threads directly onto compatible lenses and retains front filter threads for stacking with polarizers, UV filters, or other accessories. A plastic storage case is included for protection when the filter is not in use. For photographers who want more or less diffusion, the Soft/FX line is available in multiple densities, with 1/2 sitting at the milder end of the range.
