Hi everyone,
I just got my R7! I also picked up the RF 100-500 for birding. I'm new to photography and can't seem to figure out how to quickly switch from AF to MF so I can use the control ring on my lens to focus. In many cases AF works great but when my subject is far away, the AF isn't as precise as I need it to be. When I see this happening in AF mode, is there a way to quickly switch to MF and improve the focus manually?
How far away is it not focusing on subjects. It is by all accounts better than R5 and that is good.
Great shot by the way.
Thank you! ❤️
Mostly this happens with large distances (50+ yards) but I’ve seen it happen with less. When it does happen, it’s almost always a bird in a tree where the tree the bird is on appears in focus, but the bird itself isn’t as sharp. I’m hoping that a slight manual adjustment will make the difference but open to other suggestions!
Most people including myself use two back buttons to focus. One set to a single point, for situations such as this. The other set to multi point with eye focus.
Not sure how you have yours set up. there are loads of examples on YouTube.
So I followed this video to setup my back button focus: https://youtu.be/vpEGBiIMAZk
The AF with the back button seems different the AF I get in auto mode. In auto mode when I half-press the shutter I get a beep and green boxes. Both are missing when I press the back button AF. Is this expected?
I’m also noticing that the the back button auto doesn’t detect birds as well and doesn’t seem to have any eye detection (even though I’ve got animal + eye detection enabled).
I think I was just shooting in low light so eye detection wasn’t able to do its thing. It was 6:30am. Now it’s past 7 and I can confirm eye focus is working! Although I’m still a little confused re: the difference in AF behavior between auto and back button.
