⚠️
Note (Focal length / calibration):
Not all focal lengths are an exact match (for example 35mm vs 37mm). To make the comparison as fair and usable as possible, the shots have been calibrated so both images align properly in the viewer. As a result, some clips may be slightly cropped and/or have a small position shift applied. You can disable this calibration in the Advanced menu.
⚠️
Note (T-stop / exposure compensation):
Some lenses may show a small shift in T-stop because these are vintage optics and real transmission can vary. To keep the comparison consistent, exposure has been matched in the grade so the tool performs at its best. You can turn off this exposure compensation in the Advanced menu to see the actual recorded exposure.
