Currently I have an SE. It takes serviceable pics, but not quite the quality I want/need. I prefer shooting with my DSLR, but obviously as many know, the best camera is the one you have with you. And since my phone is always with me, it provides opportunities to catch moments I wouldn't otherwise. Because of this I'm considering a 7, 7 Plus, 8, or 8 Plus. I have no interest in the X. The dual cameras are appealing, but when I had a 7 Plus prior, I only rarely used the portrait mode, and 2x zoom gave less than ideal results with the lack of OIS on the telephoto lens. Are the 8 and 8 Plus significant enough in improvement to justify over the 7 or 7 Plus? I could see some of the new photo modes coming in handy, but can recreate them in photoshop as well. If you were buying based on the camera today, which model would you go with?
