ADA4351-2 Input capacitance & feedback capacitors

Category: Datasheet/Specs
Product Number: ADA4351-2

I am considering the ADA4351-2 to convert photo diode currents into voltages.  Some of the photodiodes have long cables however which means a large input capacitance (up to 1 nF) to the TIA.

To prevent oscillations in our own TIAs I use feedback capacitors. The datasheet makes reference to 'internal compensation' reducing the need for external compensation capacitors but doesn't specify any further. 

  1. What input capacitance (for what gains) can these TIAs handle without compensation?
  2. Will adding external compensation capacitors be ok?
