Tentang file PEFPerbandingan Keunggulan
AVIF Keunggulan
- Best-in-class compression efficiency — 30-50% smaller than JPEG for the same quality.
- Royalty-free and patent-unencumbered (unlike HEIC).
- Supports alpha transparency, HDR, wide gamut (BT.2020), and up to 12-bit color.
- Progressive decoding: a blurry preview appears while the file is still downloading.
- Supported in all major browsers since late 2022 — no polyfills needed.
PEF Keunggulan
- Full Pentax sensor data with 14-bit or 12-bit depth.
- Rich Pentax makernotes for lens and filter metadata.
- DNG alternative available on body — user choice of archival openness.
- Every major raw processor supports PEF.
Keterbatasan
AVIF Keterbatasan
- Encoding is CPU-expensive — an AVIF export can take 10-30× longer than JPEG.
- Older software (pre-2022) cannot open AVIF without plugins.
- Email clients still largely ignore it — stick to JPEG for attachments.
- Metadata support (EXIF, XMP) exists but tooling is less mature than for JPEG.
PEF Keterbatasan
- Proprietary with no public spec.
- Niche market share — Pentax DSLR sales are a fraction of Canon/Nikon/Sony.
- Lightroom profile coverage trails the Big Three.
