Hello Haris, I echo the previous post in using what you already have. What a wonderful opportunity that you have to document your country's and society's changes in the time ahead. Bigger is not always better. One can produce some wonderful work with medium format. The expense of using medium format is more manageable. I can see a day when your documentary of your country in transition would be applauded by the masses. Good luck to you, no matter what you choose to do.
