Changing Lenses in waterproof housing
I've done some research but nothing I find helps! I want to take my 500d to the Holi Festival (the one where they throw coloured powder and water around). I want to buy a waterproof housing which is obviously affordable.
I would like to know if anyone knows an affordable and reliable brand but mainly how to change between my 10-22mm and 85mm. Can I do it whilst still in the case? Is there a waterproof case just for a lens?
Any tips or advice, especially from people who have been to the festival would be amazing! Many thanks!
