IRIX is one of the lesser-known lens manufacturers, but they produce some rather interesting lenses that promise high levels of image quality, particularly suitable for landscape photography. The 15mm f/2.4 Dragonfly offers a fairly wide maximum aperture paired with an ultra-wide focal length, all at a modest price, and this excellent video review takes a look at the sort of performance and image quality you can expect from it in usage.
Coming to you from Christopher Frost, this great video review takes a look at the IRIX 15mm f/2.4 Dragonfly lens. At $599, the 15mm f/2.4 is fairly affordable. Though it is a manual focus design, considering its focal length and designed applications, that should not be a particularly bothersome issue. It comes with a nice range of features, including:
- Two aspherical elements and two low-dispersion glass elements for reduced distortion and vignetting and increased sharpness
- Neutrino coating for fewer flares and less ghosting and deeper contrast
- Positive focus lock mechanism
- Declickable aperture mechanism for video work
- Large depth of field scale
- High level of build quality and weather-sealing
While not the sharpest lens on the market, the 15mm f/2.4 seems to occupy a good middle space. Check out the video above for Frost's full thoughts on the lens.
