Pentax D FA 24 70mm HD F 2 8 ED SDM WR Review | 54 Data compared

The HD Pentax-D FA 24-70mm f/2.8 ED SDM WR is praised for its outstanding central sharpness, effective weather sealing, and quiet SDM autofocus. Its robust construction, including ED and aspherical elements, delivers high contrast, though the lens is heavy (787g) and lacks built-in stabilization. Performance drawbacks highlighted include soft edge sharpness at f/2.8, significant distortion, and noticeable vignetting when shooting wide open. While offering a versatile zoom range with a useful lock switch, the 82mm filter size and weight may be considerations for long-term handling.

The HD Pentax-D FA 24-70mm f/2.8 ED SDM WR is a high-performance, weather-sealed standard zoom designed for full-frame Pentax cameras, featuring an advanced optical formula with ED and anomalous dispersion elements to control aberrations. Key strengths include a constant f/2.8 aperture, quiet and accurate Supersonic Direct-drive Motor (SDM) autofocus, and robust construction suitable for challenging environmental conditions. On the downside, the lens is notably heavy and bulky, which may hinder extended handheld use. Technical limitations include substantial barrel distortion and vignetting at 24mm, a lack of optical image stabilization, and a moderate minimum focusing distance.

The Pentax-D FA 24-70mm f/2.8 ED SDM WR is a well-built, full-frame K-mount DSLR lens that offers a classic shooting experience at a relatively affordable price point compared to modern mirrorless alternatives. Weighing 812g with the hood attached and measuring 109.5mm in length, the lens balances comfortably on chunky DSLR bodies and features a robust, weather-sealed construction. Optically, it excels by delivering rich, accurate colors, smooth rounded bokeh, and a highly pleasing, streaky lens flare. Its center sharpness remains strong and reliable across the entire zoom range, even when shooting wide open at f/2.8. Additionally, manual focus users will appreciate the inclusion of a classic focal distance scale window alongside a handy zoom lock switch at 24mm. However, testing reveals notable drawbacks when navigating demanding photographic scenarios. The autofocus performance is prone to misses, particularly in limited low-light environments or when tracking fast-moving subjects heading straight toward the camera. Photographers must also contend with prominent barrel distortion at the wider 24mm focal length, which remains visible in both JPEG and RAW files. Corner vignetting is another issue when shooting against...

The HD Pentax-D FA 24-70mm f/2.8 ED SDM WR is a robust, professional-grade zoom lens delivering stellar, near-prime sharpness and excellent color rendering across its range. It features durable weather-resistant sealing, a fast and accurate SDM autofocus system, and is nearly free from chromatic aberrations. Conversely, the lens is heavy at 887 grams, requires large 82mm filters, and utilizes an external zooming mechanism. Optical compromises include strong vignetting at f/2.8 and noticeable barrel distortion at 24mm.

The HD Pentax-D FA 24-70mm f/2.8 ED SDM WR is identified by ePHOTOzine as a crucial, high-performing standard zoom lens for full-frame Pentax K-1 users, featuring a robust, weather-resistant construction. It provides exceptional sharpness across the frame and excellent bokeh, all at a lower price point than many competitor f/2.8 alternatives. ePHOTOzine While offering high performance, the lens is heavy at 787g, which may feel unbalanced on smaller camera bodies, and it requires expensive 82mm filters. Despite these points, its consistent f/2.8 aperture and robust weather sealing make it a versatile choice for professional shooting conditions. ePHOTOzine

The Pentax HD D FA 24-70mm F2.8 ED SDM WR is a robust, weather-sealed standard zoom designed for full-frame Pentax DSLRs, offering strong central sharpness and a constant f/2.8 aperture at a competitive $1,099.95 price point. While offering great value, the lens suffers from soft corners, significant edge distortion, and vignetting when shooting wide open, alongside a heavy, 1.7-pound build.

This review highlights the HD Pentax-D FA 24-70mm f/2.8 ED SDM WR as an essential, high-performance standard zoom lens co-developed with Tamron but built to strict Pentax specifications using premium Hoya glass. Tested on a Pentax K-1 Mark II, the lens features a robust, weather-resistant build, a quiet and fast SDM autofocus motor, and the convenient Quick-Shift manual focus system. Optically, it delivers excellent contrast, high image homogeneity, and strong color reproduction, achieving its best performance when stopped down to f/4. While its 0.79 kg mass feels bulky, it remains well-balanced on full-frame bodies, and its independent front filter thread ensures that polarizing filters do not rotate during zooming or focusing. However, the lens comes with several drawbacks, including a somewhat cheap, plastic exterior feel and an ergonomic flaw where the 8 mm focusing ring is too narrow for comfortable handling. Optically, its weakest performance occurs at the wider 24–35mm focal lengths, where users will encounter noticeable chromatic aberrations and cylinder (barrel) distortion at full aperture. Vignetting is also visible at f/2.8 across the entire zoom range, though it fades...
