Olympus Lens - Focal Length Comparisons

As a way to evaluate the performance of Olympus OM System lenses mounted on a Canon EOS 5D Mark II using a 3rd-party lens adapter, I made this series of images.  The images were made from the same location, using a level tripod and camera.  This is not a scientific test - just a practical one to see how well the lenses put an image on the sensor.  All images were made with the lens at the smallest lens opening for that particular lens. 

The last three outdoor images were made at a different time using Super-Multi-Coated Takumar lenses with the Canon EOS 5D Mark II and 3rd-party lens adapter.  I have included these images because they provide an interesting extension to the comparison.

The series show the difference in the image made by changing focal length.  Scientific conclusions cannot be made about color because the camera was set on auto-white balance, causing the camera to make changes for each image, preventing a valid assessment.  Reasonable conclusions may be made about sharpness though these images were sharpened at the same time they were reduced in size for presentation here.

A link on the main image page (click the image below to enlarge) will take you back to the lens data page where may be seen a crop from the original, full-sized file.  From this may be observed more useful examples of lens performance during this shooting.
