This version is the longest of the series. The Version 9 I use for years, only longer bright Teles not fit in there. So I relied on the specified internal dimensions and bought the new version 10. The course was very naive, because almost all manufacturers tables the customer as to fairy tales, so here also. The width is not 20 cm, but at best, 18 cm, but even very top of the zipper. The width is reduced rapidly to only approx. 7-8 cm. That's for Teles, particularly with turned upside down sun visor, too little. The depth of allegedly 16 cm above 11 cm, below only meager 6.5 cm.
On the side of the bag each is a tab, can be attached to the other accessories, usually Objektivköcher (MAS) system, a huge advantage over other bags.
Conclusion: A very good and very flexible solution with accessories, but you have to take into account the actual interior dimensions. Now you can worthy of debate, how many points you should pull it, I pull from just one point.
