GT35pro Standard vs GT35pro Advanced

I've been asked many times what's the difference between my gt35pro Standard and Advanced version so here are the 2 test charts to show the difference. The Advanced version has close to no no chromatic abberations and the Standard version has a slight touch of chromatic abberations at the edges. You will not see the chromatic abberations unless you zoom in to the picture 200 percent at the extreme corner of the frame to notice it. The picture quality is almost identical. Note that this is shot using my Digital Rebel 300D 18-55mm kit zoom lens at 50mm f5.0. Both version features very good edge to edge sharpness. The advanced version is also a tad brighter due to the multi coating on all sides of the glass in the achromat. You can see that in the test charts. The difference in picture quality is very small but there is a price difference of $55. For those who want the perfect picture quality, the $55 may be well worth it. Also note that all other adapter makers do not display test charts.
