I have both ff and crop sensor cameras but I haven't got rid of my aps-c crop sensor yet because its many benefits. I find them more compact in my hands even with a battery grip. The 1.5 reach is great for those closeups. I know the option is included in ff but still the size and weight of the camera trumps the option. The lenses are another thing. Less glass cheaper buy and weight. Its too many to dismiss. I think I am a lifer with this setup. Do you guys owned both? What you think about the two form factors?
I did - for 9 years (Canon 20D and Canon 5D).
I recently switched to all-crop (Canon 7D Mark II). There were many reasons for the switch but size was not among them as the 7D is the same size as the 5D.
I have a 6D along with a few crop bodies, and I noticed something in the exposure characteristics between them, curious if you also noticed this. I'll preface this by saying I'm an occasional camera user, so I haven't shot thousands of images to analyze this, its more of a seat of the pants thing.
If I'm shooting anything with the sunny sky in the background (Calif) the 6D tends to underexpose compared to my crop bodies. If the horizon happens to be in the vertical center of the frame, I think the 6D tends to meter more of the sky exposure, and the crop body tends to average it out a bit more.
What I think may explain it is just like the focus points in the crop body take up a larger area in the frame, I suspect the CWA zones are different too. Have you noticed something similar between your 5D and crop bodies?
