Here's a comparison of the X14-42mm (at 35mm, on the right) and the 14-140 (at 32mm, at left). Both were shot n RAW, hand-held, f5.6, 1/1250, ISO160, and with stabilisation. This is a shot of tree across the street. This is a 2 to 1 crop from Lightroom. The crop is from the near-centre of the frame. No sharpening for the crops, but the full frame below has Lightroom's output to JPEG sharpening.
