Is it possible to DMA DCMI data to external SPI PSRAM (8MB)? I don't have enough pins to place SDRAM and wish to buffer Camera data.

Yes this should be possible. The OCTO or HyperRAM SPI PSRAM has to be in Memory Mapped mode to do this.
Be award that there are limit's (and Errata's) on some STM32 MCU's when using external PSRAM's.

Thank you very much I will try.
