Gt35pro 35mm adapter test charts
 

I've been asked many times what's the difference between the gt35pro Standard and Advanced version so here are the 2 test charts to show the difference. The Advanced version has close to no chromatic abberations and the Standard version has a slight touch more chromatic abberations at the edges than the Advanced version. You cannot see the chromatic abberations unless you zoom in to the picture 200 percent to notice it. 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 slightly brighter due to the multi coating on all sides of the glass in the achromat. The difference in picture quality is very small but there is a price difference of $75. For those who want the perfect picture quality, the $75 may be well worth it. Let me know that you guys think about this. View the test charts below
