Went out to try my new Sigma 50-150mm f/2.8 today and got this among other, less interesting shots: It's a crop roughly 1/4 of the original photo. It is rather soft, shot at f/2.8 and ISO 400. Processing is levels adjustment and light sharpening with high pass filter. Any comments welcome. Looking at the exif now, i find it curious how only the right wing is blurred, altough i really like the effect. Shutter speed was 1/800.
