Last week I decided to invest in a new lens, and with my increasing interest in Landscape photography I decided an ultra-wideangle lens was the way to go. A friend introduced me to MPB Photographic a while ago and I've often window shopped, but this time I picked out the Sigma 10-20mm F4-5.6 EX DC HSM. This lens would normally be well out of my price range, but as a second hand lens in near min condition, the price was much more reasonable.
I'm not an expert on lenses so I'm not going to give you a detailed explanation of how the lens is constructed or anything technical like that. What I can say is that this lens is sharp as hell and it's a valued addition to my camera bag. So far I've only used it for taking sunset shots, as there's nothing nearby where I live that I can get to before the sun sets after work, but that will hopefully change this week as I have some time off work. I've already got a trip planned to Brimham Rocks next week, so hopefully that will provide me with some suitable material for a good test of this lens.
Here's a few details I've borrowed from Sigma's own site, and here's the link in case you'd like to know more: -
- 102.4 ° at 10mm and 63.8 ° 20mm
- Minimum focusing distance of 24cm
- Three aspherical lens elements offer excellent correction for distortion and Three SLD (Special Low Dispersion) glass elements employed for effective compensation of color aberration
Internal Focusing System allows the convenient use of a polarizing filter for creative effects & improves the optical performance of the lens at various distances
