Full frame or not to full frame? That's the question

The magnification increase caused by using a smaller format occurs in the display stage. The lens projects the same size image on whatever format sensor. If the scene is composed with the same field of view then the smaller format requires a greater enlargement factor to get the same size print as the larger format. Technically increasing the enlargement factor decreases image quality, although it may have to be pushed pretty far to see quality differences in the real world.

Whether or not a smaller format would be more efficient at longer focal lengths for in-camera cropping depends on photo receptor size, quantity, and density so you have to compare specific sensors and not just format. If you are using an APS-C format camera that has significantly more mp, then it probably is more efficient. Compared to a 35mm format camera with a similar amount or more photo receptor quantity/size/density then cropping the larger format in processing may be better. For instance if I crop my 21mp 5DII to the same field of view as my 10mp 40D I'm going to end up with a higher pixel count image (about 13mp). At that point as long as I crop them the same way the 5DII shot is always going to have more pixels than the 40D shot. On the other hand if I compare a 7D (16mp?) to my old 5DI (12mp) then the opposite is true.

My mis-focus rate with your three worst cameras is about 1 in 1000 shots. That may be horrible compared to the latest wang-doodles, but in my world that's well beyond the limit of idiot proof.


Jump into a 1d series cam or the 5d mark III and you'll hate your AF on the other cams...A LOT.

If you are not totally bought into any system yet, I would recommend you to rent some of the cameras you want to get, and try the cameras before you make up your mind if want to swap sensor size, camera make and so on. And don't get to hung up on the AF. AF is only important if you shoot sports, journalistic or wildlife. If what you're into is macro and landscapes, you don't need a snapping AF since you have enough time to manual focus when it comes to both landscape and macro.
And when it comes to Nikon D800/E, this is not a general purpose camera. If you don't need those large files, there is no point in investing in that camera. A D600 is more than up for the job (even with clustered AF-sensor nest in middle of the view finder). And as I said in another thread here with regards to that, it's like getting a souped up Corvette Viper to use it only to drive to supermarket and take the kids to football practice.
And there is the cameras of yesterday on the second hand market, though discontinoued, they still present you with much camera for years to come. But what to look for at the second hand market is an entire thread in it's own.

Looked quickly at your zenfolio. I saw nothing there that needs tracking AF. Still like Scotty said, try something better and you'll realise what you were missing. Being able to track a moving object is great.
