The weather has been miserable lately, but we finally got a fine day on Sunday, so I went out late afternoon to one of my favorite coastal beaches to try the 10-20mm out.
|9 Mile Beach - Nikon D90 with Sigma 10-20mm @ f8|
The Sigma 10-20mm f4/5.6 EX lens is a solid, compact lens with a fast and quiet HSM focusing motor, which allows for full-time manual 'tweaking' of the focus, even when you remain in autofocus mode. Not that you really need to tweak the focus on an ultra-wide. Set it to f8 and just about everything from front to back will be in sharp focus (see above).
|Same settings as above. Why change a winning formula :-)|
The lens is finished in the famous Sigma 'matt black crinkle' which also, famously, tends to wear off - although my lens shows no signs of that at the moment. I must admit I'm not a huge fan of this type of finish and I think in more recent models Sigma has moved away from this to a more traditional (harder wearing) finish.
|Lots of detail and heaps of colour - that's what ultra-wides are made for!|
The huge field of view that this lens afford is what makes it such fun, but also what makes it rather tricky to use effectively. Tilt the lens down and horizons will start to bow, yet not alarmingly so. The lens is actually well designed to avoid any massive distortion - but you can make it happen if you really try (and if you like the effect). Focus was fast, snappy and silent on my D90 - and the large zoom ring turns smoothly and is a joy to use.
|NOT taken with the Sigma 10-20mm. I just like the shot :-)|
I'm very happy with the lens, and with the first images I've taken with it. Hopefully, over the course of this summer, there'll be plenty more where that came from.
