I am a fairly new photographer and take pleasure in taking pictures of my travels and my family. I have an Oly 14-150 that meets 90+% of my needs. On my most recent vacation I found myself having to back further and further away from my subject to get the desired background with my lens backed down to 14mm. After viewing the link below that I found floating around in another thread it made me realize just how much wider I would like to be able to go. Olympus Zuiko lens field of view comparison Is there an underlying reason why Panasonic or Olympus doesn't make a 7mm, 8mm, 9mm, or 10mm prime? Is it easier to produce a wide zoom as opposed to a prime?
