Pentax-DA 18-270mm F3.5-6.3 Review
Specifications
The Pentax 18-270mm zoom is designed exclusively for digital cameras and only covers the APS-C image circle.
This lens foregoes the traditional Pentax screw drive focusing mechanism and features a built-in super sonic focusing motor (SDM) only. This means that this lens will not autofocus on certain early Pentax DSLRs: the K100D, K110D, and *istD series.
Below are the official lens specifications:
| Lens Name | SMC PENTAX-DA 18-270mm F3.5-6.3 ED SDM |
| Optical Formula | 16 elements in 13 groups. Two of the elements are ED (extra low dispersion) |
| Image Circle | APS-C Only |
| Autofocus | Built-In SDM Motor |
| Field of View | 67° to 5° horizontal, 75° to 5.5° diagonal |
| Aperture Range | F3.5 - F22 at 18mm F6.3 - F45 at 270mm |
| Aperture Blades | 7, rounded |
| Aperture Ring | N/A |
| Max. Magnification | 0.26x |
| Minimum Focusing Distance | 49cm |
| Internal Focus | Yes |
| Quick Shift | No |
| Filter Diameter | 62mm |
| Cap | Plastic, pinch type |
| Hood | PH-RBD 62mm, included, petal-style |
| Case | None included |
| Diameter x Length | 75.8 x 89mm / 3 x 3.5 in |
| Weight | 453g / 16oz |
| Mount Designation | KAF3 |
| Weather Sealing | N/A |
| Price | Current (US): $799.95 |
As this is a DA-series lens, modern Pentax DSLRs will support in-camera distortion and aberration correction when used with this lens.
