Instead of the previous lug around a bulky gray card, it is nevertheless much smaller and lighter - and with a lot more features.
In addition to the color temperature and the mean gray values for exposure setting, there are white and black values, absolute black and the small chrome ball on top of it (in the truest sense of the word), to assess the highlights.
In summary, the closing date of RAW images with this handy tool easy. So: buy!
The quality is very high, you get a small cloth bag included. The price made me initially a little surprised - However, if you consider that a good gray card also costs> 20, it is still appropriate. So full marks.
