Quick AF point question

Huh! It's been so long I clearly forgot.

I just learned that Liveview has three different autofocus modes all using the AF-ON button to focus, and the shutter sound I was getting in Liveview when pressing the back button/AF-ON was the mirror dropping down in AF quick mode. Don't think I'll bother much with Liveview.

That's why I didn't bother! it's not true electronic shutter, if it was, it could be silent.

Yeah, it's not great. However, might come in useful if I ever record video with the 50mm f1.8. I've never shot video with bokeh. :)

The 5D2 was the FIRST camera that isn't a massive cine cam that you find in movie sets that can shoot video with bokeh. Sure there were compact cameras that can shoot video but their sensors are small, 5D2 changed all that. Now Canon is putting 8k/30 in the new R5...You can shoot and project a movie with that. Or pull stills from it.....
 
A couple of other points to remember.
  • To get good, sharp panning photos you will need to adjust your shutter based on the distance and speed of the subject. A road car further away will typically require a slower shutter speed (E.g. 1/60) vs a Superbike from the side of the track (e.g. 1/125).
  • Don’t forget the shutter speed / focal length rule, especially if your lens doesn’t have IS / IS panning mode. If you are shooting with the shutter speed set slower than your lens focal length without any IS, then your panning technique needs to be super smooth. Else the subject blur you see won’t be caused from missed focus but camera shake.
Here are a few panning shots I took using a Canon 20D and 100-400 L IS, all standing at the side of a track at 1/125

Wow, those are great shots SDK! Very well defined cars and bike.

"Don’t forget the shutter speed / focal length rule".

I was using my 70mm to 300m lens at 70mm minimum focal length when I did my panning the other day, so does the rule mean my shutter speed should have been 1/70th? I did have IS on though.
 
IS isn't going to help you in panning, IS helps you when you are trying to keep the camera still. You are not, you are panning.

That’s not true though is it. Lots of lenses and camera bodies with IS have modes designed to be used whilst panning.

Some Canon lenses have 2 or 3 IS modes.

Mode 1 is the standard two axis operation (pitch and yaw) in which the camera attempts to correct any movement it detects. This is the standard mode intended for stationary subjects.

Mode 2 is intended especially for panning. It is designed to ignore motion in the direction of the panning, but to correct any detected motion at right angles to the panning direction.

Mode 3 is for photographers who don’t want the viewfinder image to be affected by IS. In this mode, stabilisation is applied only during the actual exposure.

Some recent IS lenses dispense with a mode switch altog
