In order to test the resolution of cameras for which there were no evaluations yet, I was forced to carry out tests myself. But I had never done this seriously before, so I had to find out more first. There are many tips online, but they were either too technically complex or they were just the author’s emotional assessments.
I was tired of hearing ‘creamy bokeh’ and ‘sharp corners’ in lens review videos. With a little effort, I could carry out meaningful lens tests at home. The results may not be as good as professional laboratory tests, but in most cases they were sufficient to get to know my own lenses better.
