Thanks, Aussie shooter, for responding to my post. Looks like you will have all your bases covered.
Be sure to get the 7D II in plenty of time to learn the AF system. It is a bear! In fact there is a whole manual that you can download just for the AF system. It took me a couple of thousand shots to become comfortable with it. But for still shots it won't be too much different from all the other cameras. When you are shooting fast moving subjects, be sure to keep the shutter speed high enough or the subject's movements will make you think the camera is not focusing properly. For BIF I usually keep it over 1/2000 sec. But once you have become adept at using the focus system, you never want to go back to the other AF systems.
One thing I discovered by accident is that, unlike all my previous cameras the Scene Automatic setting, (green square), will allow you to shoot in RAW. The camera does all the work, but the downside is that the AF is set to use all the focus points only so you have to be aware of what subject is closest as the camera will focus on that. Normally, though, I shoot RAW in Manual mode to be able to use all the AF features.
Being a crop sensor, the noise is more pronounced than on a full frame camera so be sure to buy good, sharp, fast lenses. The 5D classic should still give you wonderful photos in spite of its age.
Cheers again, mate.
