Great bit of kit
Advantages: This is a great camera .. the output via wifi as preview may suffer in quality but this is outweighed by ZERO lag and the final images are quite stunning.. the settings are awesome.. exposure is a joy to play with and it goes to ISO 100-1600 The 20.2 mp image is actually interpolated from a 14mp sensor so 14mp is the setting of choice.. 20.2mp just adds noise.. ...OK to make this more usable, use a decent powerbank with dual outputs.. for your phone and the camera.. It will function normally whilst plugged in .. But use the lower amp rated port to charge the camera. The final stage in the tiered lense system is a 62mm screw ..so you can use 62mm adapters and lense hoods.. and I have mocked up a 62mm telescope fitting for it rather successfully . I have mine sat in a 15mm rail system with barn doors.. it looks sexy :)
Limitations: short battery life -- use a powerbank
