Blossom End Rot

Does anyone else get this on their tomatoes please ? My plants look fine and Im maintaining even watering, but I still get this on quite a few of the fruits. Can I do anything ?

Thank you

Hi Blueroses. Once the tomatoes have BER there's nothing you can do about it.
I get it with the bigger varieties - Marmande and the like - so I don't bother to grow them anymore.
The smaller varieties of tomatoes are trouble free in that respect.
