What lens are you using?

We use 9-18mm Olympus on I2 for survey and all other photo jobs with an large contractor.
 
6hours of flight now. It balances ok. Have not done anything extra.

The zoom has to be manually adjusted before flight :-(
 
Im starting out with real estate than going into survey and farming.
Can you attach any pictures you have taken?
Also, did you have to order or do any balancing for the lens?

Thanks
