Carry-on: You should be fine with the camera bag and another bag.

Other baggage: Once you understood that there are two different kinds of charges, it's quite simple. They charge for every kg above 20kg and for every bag above the free one. In detail:

• You are allowed to bring one bag with a maximum of 20kg for free
• You can bring as many bags as you want, but you have to pay 15€ for each piece (one is free). You can buy extra bags online at the time of booking for only 7.5€ for each.
• You can bring up to 50kg in total, but you have to pay 7.50 for each kg above the 20kg limit. And - as always - one bag mustn't weight more than 32kg

So let's make some examples to illustrate that :
You will have 2 bags with a total weight of 29kg: You will have to pay 15€ (for the 2nd bag) and 9x 7.50€ for the excess baggage
You will have 4 bags with a total weight of 49kg: You will have to pay 3x 15€ and 29x 7.5€ (no bag heavier than 32kg)
You will have 2 bags with a total weight of 19kg: You will have to pay 15€ (online at the time of booking: 7.5€)
You will have 1 bag with a total weight of 27kg: You will have to pay 7x 7.5€
You will have 1 bag with a total weight of 19kg: You won't have to pay extra


To sum up: As long as you have not more than 50kg, you will be charged, but allowed to fly! And if the flight isn't sold out, they will also accept 200kg (180x 7€ plus charges for additional bags)
