I heard also that P30 is not suitable for tilt camera and still-life setting due to the design. P25(+) or P45(+)(also of course P65 and IQ 140,160, 180...) should be better. In still life setting, a normal lens is around 100, for example, schneider 100 digitar lens can be a starting point for still-life setting. 80 becomes a little!! wider lens and 120 becomes a little!! long lens. Degitar or digital lenses are usually better. For the macro work, schneider 120 macro digitar is respected... A big advantage is the fact that you can use tilt (and swing). You can control perspective and focus plane using bellow cameras. This control can be important in some areas of photography.
You have a good choice of lenses. A disadvantage is ...it can be very complicated regarding with the equipment and skills to handle those, for the beginners... you need some skills and a lot of infos to deal with this set-up... It can be expensive to have the right set-up too. It might be a good idea to study enough before you start to buy things.
