In this test, the 35mm lenses were mounted on a Chinon manual Bellows unit. The extension needed for the 135mm was >100mm, which is max. possible for this bellows. The 100mm needed ca. 60mm extension. | ||

At this distance, the 120mm performs slightly poorer than the others, IMO. | ||

Here, the difference angle of view between the lenses is more noticeable. Since the details section are about the same area of image surface, the level of detail should increase with focal length if the resolution is the same. This doesn't happen, however. Look at the detail page on the hillside for more comments. | ||
