Sample Images

Ok, finally here're some sample shots taken with the EOS 350D (converted RAWs via RSP v1.0). 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

The EF 300mm f/4 USM L is a superb lens which is capable to deliver an almost flawless performance in all aspects. Adding the EF 1.4x II converter only results in a slight decrease in quality equivalent to about a school mark. So if you can live without image stabilization (which is very useful in the field) there're no reasons to "upgrade" to the current lens. At the end of the day the EF 300mm f/4 USM L remains a highly recommended lens!
