Most photographers probably had the same wish in the past. The first time you picked up a wide-aperture lens, you wished there was a zoom lens with a constant aperture larger than f/2.8 that you can use everyday.
The common, rational, and technology-imposed limits state that you can have such a lens, but it’ll be very big, heavy, and expensive. While all of these are true, Sigma seems to declare “well, we’ll still do it!” with this latest exciting rumor of the Sigma 18-35mm f/1.8 DC HSM.
First sighted at a Czech photography website Digiarena, then later reported by the good folks at PhotoRumors, the lens looks like it’s designed for APS-C cameras in mind. Possibly with the usual Canon, Nikon, and Sigma’s own mounts.
Here are some of the rumored specs of the Sigma 18-35mm f/1.8 DC HSM
- Designed for APS-C based DSLR cameras
- Ultrasonic auto focus (HSM)
- Type A (Art), which guarantees quality materials, metal bayonet
- 9 aperture blades
- Filter size: 72mm
- Maximum aperture: f/1.8
- Minimum aperture: f/16
- Lens construction: 17 elements in 12 groups
- The maximum magnification ratio: 0.23x
- Weight: 810 grams,
- Total Length: 121mm
- Angle of view: 76.5 – 44.2°
- Internal zoom and focusing
- Minimal focusing distance: 28cm
It seems too late for an April Fools joke, and I’m not sure the Czech folks celebrate that anyway, so let’s keep our fingers crossed that this will come to life.
810 grams for wide to normal angle lens is mighty heavy though, but I’m sure most DSLR users won’t mind.
