Well, I think this answer can be addressed technically of course but first lets approach it from a personal standpoint. First, the IPhone 5 has a larger screen but still an 8-megapixel camera This version does have, a new sapphire-crystal lens, and improved hardware enabling features like dynamic low-lighting adjustment, image stabilization It’s on the 1080p video camera, and the capability to take still shots while shooting video.
The other advantage include is fact that it is carried wherever we go, have all the pictures we ever took on it in our pocket, and of course can share (or bore others to death) instantaneously with a click of send or upload. Recently we went to a wildlife park with both our Iphone and our DLSR and I have to say when looking at the pictures side by side, they were pretty even in quality. I noticed the shutter was quicker vs. my 4 and although they haven’t upgraded their megapixels, I was pleased with the end result.
Another upgraded feature was the u quality of the low lit pics where I failed to use my flash– not camera quality but nicer. I have to say the one area where the Iphone will always trump the DLSR is that I don’t have to schlep it with me, I don’t have to worry if I brought the lens, are the batteries working, did I empty the card and who is going to carry it all day. Even a small thing as the noise factor of a camera working is a nice element of the Iphone. At the end of the day, an Iphone is just that – it’s a phone with features, not first and foremost a camera.
Professionals and amateur photographers alike I think will still lean towards a DLSR and who can blame them. A dedicated camera will never compare to device that’s full of other features. Lets face it, a phone will never perform in low light conditions the way the DLSR will. It also doesn’t need a flash to capture images like the Iphone will and it doesn’t, in most cases, require a flash. Also you can set your focus point, have greater control over exposer and what it is exactly you want to pinpoint as the feature in your shot. Also, you can only manipulate a JPEG so much whereas an actual photo has endless possibilities and allows the photographer manipulate and edit the picture make a statement if he so wishes.
Both have pros and cons of course, so it come down to one question – Do you want ease and convenience or do you want to work a little harder to achieve quality?
