PThomas Posted February 15, 2007 Share Posted February 15, 2007 I took a photo with my digital camera earlier today, the end of the drive is approx 10m from the house. What lens will give me this coverage (or slightly less width)? Link to comment Share on other sites More sharing options...
luggsey Posted February 15, 2007 Share Posted February 15, 2007 I would say that is between 4mm and 6mm. If you have a varifocal camera fitted, you can adjust it to the exact coverage you need. Be careful not to be able to see into your neighbours window. Who knows what you might see with a 4-6mm camera lens! Lights on or off or curtains open or shut lol.... ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!
