give some idea of what the Slightly Longer focal length and wider openings mean in terms of background defocus and subject isolation.

Compared to the Panasonic Lumix G 20mm F1.7 ASPH
Shot a couple of (very) quick comparisons with Panasonic's popular and highly-regarded 20mm F1.7 pancake prime - one of our favourite lenses of the past few years. We've shot the same image with both lenses set to their maximum aperture, using the Panasonic DMC-G3 at ISO 160. In both instances we've attempted to recreate approximately the same framing - meaning the 20mm shots were taken closer to the subject. |
