Can someone explain the real differences between a full frame camera and an APC format camera. It seems to me that the higher end APC cameras have more to give than the full frame versions. They are somewhat less expensive, lighter, smaller, have more lenses available to them and the sensors seem to be more advanced. Am I missing something here? I currently own a Canon 40D and T3i, both are APC, and as stated in a prior post, looking to replace the 40D with either a 70D or 7D, also both APC. I have gotten some very informative responses with suggestions on these to cameras, but also many suggested going to a full frame format. I looked into some comparisons on line between some full frame Canons and the 70D, or 7D, and fail to see any real benefits to purchasing a full frame version.

Why is it going backwards? I see it more as going in a different direction. The capabilities of the bridge camera is constantly improving. There is a Panasonic bridge camera on the market that has a Leica lens with f2.8 through all focal lengths. I think many forget that today's DSLRs are very sophisticated computers and it is just a matter of time before camera processors will be able to make up for shortcomings of the lens. Think about it, it was just a short time ago when many of the features in todays cameras had to be purchased as software for use in PP.

I was talking with a friend yesterday and he wants to take one of my photos and do a full wall scene in his newly remodeled home.

The photo is a very sharp scenic view, with a couple of elk standing in the foreground and some huge mountain scene in the background.

The photo is only 10 mega pixel, so I know without doing something, it can't be blown up to the size he wants without running it through some sort of program.

With that said, I was talking with a guy last summer when I was out shooting some wildlife photos that told me he no longer worries about mega pixels and his only concern is getting a good sharp photo because he said there are several good programs out there that will allow you to blow up the photo to almost any size you want without loosing the quality of the photo.

Now my question-----Is he correct, and if so what program or programs do you suggest, and how big could one blow up a 10 meg photo with them and still have the quality that was in the original photo? And if such programs exist, how much are they, and how hard or easy are they to use for a handicapped computer person?

I can't think of a better place to bring this question than to UHH for a fast and accurate answer.

I appreciate your reading and responding.

Have a great day. BB

This link helps to explain a lot. When you look at the "circle" photo it will help explain a lot. The circle is what the lens projects to the sensor. The large rectangle is what a full frame sensor sees. The small rectangle is what a crop sensor sees. You'll notice that the image in the center that the full frame and the crop sensor sees is the same size. The crop sensor has no extra "reach." A 50mm lens only sees 50mm. It is merely a difference in the angle of view, and when you print those two rectangles on similar size paper, the image in the smaller rectangle will come out larger than that same image in the larger rectangle because the larger rectangle sees not only the center image, but surrounding image as well. This is what gives crop sensors the illusion of reach.
