Irix 45mm F 1 4 Review | 54 Data compared

The ePHOTOzine review of the Irix 45mm f/1.4 Dragonfly lens highlights its outstanding sharpness, robust weather-sealed construction, and exceptional control over distortion and chromatic aberration. This manual-focus, 5-star rated lens is praised for its versatility and high performance across the aperture range, particularly when stopped down. Drawbacks noted in the review include significant vignetting at f/1.4, a heavy 905-gram weight, and the limitation of being a manual-focus-only lens. Despite these considerations, the lens is considered a high-quality, technically impressive option for photographers.

The Irix 45mm f/1.4 Dragonfly is a robust, full-frame compatible standard prime lens designed for Canon EF, Nikon F, and Pentax K mount DSLRs. It provides a natural 51.4-degree angle of view, making it slightly wider than a traditional 50mm lens. Built with electronic contacts, it communicates seamlessly with camera bodies to allow full PASM exposure mode functionality, EXIF data recording, and viewfinder focus confirmation lamps—a vital feature given that it is a purely manual-focus lens with a long rotational focus travel. Its premium construction consists of magnesium alloy and high-quality composites featuring extensive weather sealing, though it is notably large and heavy, weighing over 900 grams depending on the mount. In terms of performance, the lens delivers spectacular sharpness across the image frame, maintaining excellent edge-sharpness even when wide open at f/1.4. Its optical layout effectively minimizes lateral and axial chromatic aberrations, and its multi-layer "neutrino" coating ensures outstanding resistance to ghosting and flare. A primary advantage of the lens is its premium, weather-sealed build, alongside exceptional image quality, beautiful, buttery-smooth bokeh, and a convenient focus locking ring. However,...

The Irix 45mm F1.4 Dragonfly is a manual-focus-only lens designed primarily for DSLR mounts like Canon EF, Nikon F, and Pentax K, though it adapts beautifully to mirrorless systems due to its electronic communication and electromagnetic aperture control. The reviewer praises its exceptional "Dragonfly" build quality, which incorporates weather sealing, scratch-resistant finishes, and a highly precise, smooth rubberized focus ring. A standout feature is the innovative focus ring ridge and an integrated tension ring that allows users to increase friction or fully lock focus at a desired distance. Optically, the lens embraces a classic design choice by opting not to fully correct spherical aberrations. This tradeoff yields a uniquely artistic, dreamy global rendering characterized by stunningly creamy bokeh and rich, Zeiss-like color contrast, even though pixel-level sharpness is low when shot wide open. The primary advantages of this lens include its fantastic build execution, excellent weather sealing, exceptionally smooth manual focus action, and beautiful bokeh rendering. Furthermore, it demonstrates minimal chromatic aberration, strong flare resistance, and becomes technically flawless with superb contrast and sharpness once stopped down to smaller apertures...

The Irix 45mm f/1.4 Dragonfly lens delivers excellent to outstanding sharpness, featuring highly satisfying bokeh, minimal chromatic aberration, and exceptionally low barrel distortion, according to the ePHOTOzine performance review. Praised for its robust, weather-sealed build and solid, smooth-handling manual focus, the lens is ideal for architectural and general photography. However, the lens exhibits highly visible vignetting at wider apertures that requires correction, and the manual-focus-only design combined with a heavy construction may limit its usability for some photographers. Overall, the lens is lauded for its superb optical quality and unique 43mm-adjacent field of view.

The Pentax Forums review concludes that the Irix 45mm F1.4 Dragonfly is a robust, weather-resistant, and high-value manual focus lens that competes well with more expensive alternatives, offering smooth bokeh, low 0.15% distortion, and uniform sharpness when stopped down. Key strengths include a well-dampened focus ring, a functional focus lock, and superior build quality, positioning it as a compelling, budget-friendly option against the Pentax D FA* 50mm F1.4. However, the lens suffers from reduced resolution and contrast at F1.4, along with significant vignetting, visible chromatic aberrations, and field curvature on full-frame bodies, according to the review. Despite these optical quirks and the lack of autofocus, its strong price-to-performance ratio makes it a solid choice, notes the review.

The Irix 45mm f/1.4 Dragonfly lens for the Fujifilm GFX mount delivers exceptional image quality, striking color rendition, and impressive sharpness with high contrast that minimizes the need for post-processing. Released in April 2020, this manual-focus lens offers a 35mm full-frame equivalent angle of view while retaining a shallow 45mm depth of field, making it a unique ultra-fast option for medium-format photography. Physically, the lens features a highly robust "Dragonfly" build quality, a stepless 9-blade aperture, and a well-damped, smooth focus ring with an ergonomic ridge and an appropriate focus throw for precise adjustments. It also stands out for its remarkable close-focusing capabilities and minimal barrel distortion in real-world application. Despite its strong optical performance, the lens presents several usability challenges that make it a niche choice, leading the reviewer to ultimately withhold a recommendation for standard medium-format manual-focus users. The primary drawback is the complete lack of focusing scales on the lens body, making it exceptionally difficult to use for zone or hyperfocal distance focusing with preset distances. While the hyper-fast f/1.4 aperture is unmatched for the GFX system,...

The Irix 45mm f/1.4 Dragonfly is described by ePHOTOzine as a high-performing manual focus lens offering excellent sharpness, very low distortion (-0.28%), and low chromatic aberration. Its rugged, weather-sealed construction and 45mm focal length provide a unique, smooth shooting experience that delivers beautiful bokeh, earning it a 5/5 rating. While optically superb, the review notes heavy vignetting at f/1.4 that requires correction and points out that the manual-focus-only design may not suit all users. Overall, the lens is lauded for offering high-end performance, particularly for architectural and travel applications.
