Sample Shots

Ok, finally here're some sample shots taken with the EOS 350D (converted RAWs). Click on a thumbnail to view the original file (opens in a separate window). Please note that the full-size images are supplied in JPEG2000 format. You should be able to display the images in most modern imaging applications such as Photoshop. This is a measurement to limit the bandwidth which is a scarce resource.

If you prefer to watch the full-size samples in your Internet Explorer browser you may try the JPEG2000 ActiveX Control (Windows) plug-in. I've checked out a few plug-ins for Mozilla/Opera but haven't really found a good one. Firefox will open IE if you install the ActiveX Control above.

Verdict

We all know that zoom lenses are compromises regarding speed and performance but we expect fix-focals to perform better than that. Sigma AF 30mm f/1.4 EX DC HSM may perform pretty good in absolute terms but for a fix-focal the lens disappoints a little. The center performance is exceptionally high but the borders are not all that impressive. The other image parameters such as distortions, vignetting and CAs are Okay but nothing to rave about. So at the end of the day the only differentiator is its ultra-large aperture - it's up to you whether this is good enough compared to classic 28mm or 35mm lenses.
