I bought the Large High-Resolution Test Chart for Camera Lens off eBay for $27. Here is a link if you choose to do something similar.
Here is the setup where I had two soft boxes at 45º. I did a custom white balance using ExpoDisc.
Put the chart on a music stand and then moved the camera back as I zoomed in.
I made all the photos at ƒ/8, 1/180 @ ISO 200. I also used a tripod to be sure I didn’t introduce any camera shake into the pictures.
Below each photo is a link where you can download the high-resolution JPEG as the camera captured it. The color space is ADOBE RGB, and I chose the standard color setting comparable to the Provia color space.
My conclusion is that both of the lenses are sharp. Now, this is at ƒ/8, and later I will test the lens at all the apertures, but this is to give you a glimpse into how nice the lens performs.
