Pentax's enthusiast DSLR without AA filter — the K-5 IIs for maximum sharpness.
The Pentax K-5 IIs is a variant of the K-5 II with the anti-aliasing filter removed from the 16.3MP APS-C sensor. Removing the AA filter provides visibly sharper images — moiré is the trade-off but rarely problematic in practice. Full weather sealing, in-body SR, and professional-grade construction make it one of Pentax's finest APS-C DSLRs.
Image quality is excellent — the AA-filterless sensor resolves noticeably more detail than AA-filtered alternatives. Dynamic range is very good. In-body SR works with all K-mount lenses. 7fps burst shooting. SAFOX X 11-point AF with 9 cross-type. Weather sealed to -10°C. One of the best APS-C DSLRs of its generation for landscape and detail work.
Pentax K mount. Weight is approximately 680 grams. Build quality is outstanding with full magnesium alloy weather sealing. Dual card slots. 100% viewfinder. The K-5 IIs pioneered AA-filter removal for Pentax — the K-3 III continued this approach. Compatible with every K-mount lens. The weather sealing is professional grade.
Available at moderate prices — the AA-filterless sensor commands a small premium over the K-5 II. Check shutter count and weather seals. An excellent enthusiast DSLR — the AA-filter removal provides genuine sharpness improvement. The K-3 III is the natural upgrade. Outstanding for landscape, architecture, and detail-oriented photography.
