Time to upgrade my wireless plan iPhone 5, which is still usable but the camera sucks and it's not water resistant. As I use it more and with various camera control apps from Canon and third parties, and also for the upcoming minimalist genre of smart phone photography, the 7 and the 7 Plus are very attractive. I have some questions, regarding which hopefully users can share some insights: How much better than previous gens (especially 5) is the camera in the 7? Is the 7 Plus optically superior to the 7, or is the difference solely the 2X optical zoom? Are both 7 and 7+ going to work well with the external lens kits that are becoming available? Finally, inasmuch as September will soon be upon us, would I be well advised to wait and possibly go for the 8? Any ideas as to what the camera specs are for the 8?
