Optically excellent - sharp and good color rendition across the frame

controlled++ Generally fast focusing++ Silent operation++ Excellent, neutral color output

Nice color contrast and rendering

From my personal test of real world shots, not a test shots of charts, I can tell you Panasonic is sharper, but color and contrast of Sigma in my taste is bit warmer and vibrant.

great MFT lens with excellent sharpness and color

Very happy with this lens,found it to be very sharp right to the edge, have it on my a6000 and see it's much sharper than the 16-50 lens, bright colors, fantastic lens for the money.

It’s pretty sharp and the colors are accurate

The lens is sharp, has very accurate color, and controls very well for pincushioning and barrel distortion

so, when you shoot "standard," it actually WILL be standard; if you shoot "vivid," it will BE vivid without bizarre colors showing up)++ Made in Japan with extremely high manufacturing

Sharp, with great color rendition.

Quick focus, great color and fast lens in low lights.

This lens does the trick, with images that are crisp and detailed with nice color saturation.

I can say the color and contrast is excellent.

Aside from the rattling sound when this is attached to the camera and off (normal according to the various sources I have read), this lens focuses fast, is sharp and has very good color rendition

The color this lens produces is beautiful, and the clarity is great, even towards the edges

A really fabulous lens at crazy bargain price very sharp an great saturated colors, very very light but appears well constructedhighly recomend

I took identical picture with this lens and with my Sony 18-200mm lens (at 18mm length) and the color depth and clarity of the Sigma was near perfect

Great color and super sharp

Very sharp and great color
