I am trying to decide on my first LF camera. I shoot mostly landscape and some architecture.

I really like the convenience of roll film and the 6x9 format. On the other hand there are occasions when I would like the larger 4x5 film size. I know that some 4x5s are adaptable to 6x9. It would be nice to have both film formats in one LF camera but I am concerned about 2 things:

1 - I will comprimise some of the functions of the 6x9 format. Perhaps it be better to get a separate camera for each format?

2 - It will complicate my LF learning process.
