This post is a bit technical and, if it is not of interest, you might just want to scroll down to the pictures - I will not be in the least offended!
It is almost exactly a year since I bought my current camera set-up. My kit was getting worn out, and in need of service, but it was also getting a little too heavy for me to carry about over long distances, so I looked into going mirrorless. Having been an avid Nikon user for about twenty years, that is where I first looked. I had been using a Nikon D7200 body with a Sigma 50-500 lens. I found that if I wanted to go down the Nikon route it would cost me a small fortune, and save me virtually nothing in weight. This caused me to look at Canon. I found that there was a suitable alternative from Canon in the form of their EOS R7 with their RF 100-400 lens. This came in at about a third of the price of the current Nikon offering! Yes, the lens was not quite as versatile as was the 50-500, but the set up came in at half the weight of my exisitng Nikon set-up. Furthermore, the 32.5 megapixel cropped sensor of the R7 versus the 24.2 megapixel cropped sensor of the Nikon, made up, somewhat, for the loss of reach of the lens.
Although I was immediately impressed by what I had bought, it took me quite some time to get used to the switch between Nikon and Canon. I now feel that I'm fairly well accustomed to it.
If there is a downside to the set-up it is that the largest aperture available with the RF 100-400 is F5.6 at 100 mm (F8 at 400 mm), meaning it's a little more difficult to use at low light levels, although the lack of noise at high ISOs is rather good, and compensates for this to some extent.
One of the features of the Canon R7 is the AI driven focus facility. This can be set to recognise animals (including birds) and focus on the eyes. In servo focus mode, once the focus has been achieved, the focus will track the item, no matter where it moves to in the frame. I found this to be very useful, but I was having difficulty in achieving that initial focus, especially when the subject was a fast-flying small bird at a distance.
We now come forward to 4th March this year. I was aware of the facility to set up the R7 with three separate custom settings (C1, C2, C3), easily accessible from the dial on the top of the body. I had briefly played with this in the early days of owning the camera, but kept putting of actually using this facility. On this day, I decided that it was time to do something about it.
I frequently take photos of birds, etc. that are in confusing backgrounds or have intervening foliage in front of them. I therefore have my camera set for 'spot focus' for most of the time. It was only when reading up about the facilities of the camera that I found a recommendation that for moving subjects in an open background (sky, for example), the thing to do is to use 'whole area' focus. The AI looks for the nearest object in frame that conforms to the target focus (animals) and locks onto it.
I then set up C3 to incorporate this focus facility together with servo focus, which takes changing distance into account.
So that I can quickly get back to my static subject in a confusing background, I set up C1 accordingly.
C2 is not yet set up but I am reserving that to potentially use in the dragonfly season with settings more suited to photographing dragonflies in flight with confusing backgrounds.
The very next day, I went out specifiacally to put the C3 custom setting to the test. This is what I found.
Tuesday, 5th March Sence Valley Forest Park
I set off in the ealy afternoon with Sence Valley Forest Park being only ten minutes from our home. Having parked my car, I entered the site, stopping to photograph a pair of Canada Geese beside the path by Goss Water. Here's one of them.
Canada Goose (Branta canadensis) - Sence Valley FP |
Black-headed Gull (Chroicocephalus ridibundus) - Sence Valley FP |
The tern rafts, installed by the excellent Leicestershire and Rutland Ornithological Society (LROS) were occupied by Cormorants. I love the punk 'hairstyle' of a Cormorant in 'courtship' plumage.

Mute Swan (Cygnus olor) - Sence Valley FP |
Although the majority of gulls present were Black-headed Gulls, I am relatively positive that these two, sitting on posts out in the water, were Common Gulls - but I'm not very good at gulls! Common Gulls are not a species that I'm used to seeing in these parts.

Tufted Duck (Aythya fuligula) (male) - Sence Valley FP |
I was on my way back to my car when I heard the distinct call of a Common Buzzard somewhere. One of the problems of wearing the sort of hearing aids that I do is that I have no sense of direction of what it is that I'm hearing. However, I soon located the Buzzard as it emerged from behind trees and made some circuits high above Horseshoe Lake. I quickly turned the dial on my camera to C3 and was back in business again!

Switching back to C1, I took a few more shots as I passed Goss Pool once more.

I was, of course, highly delighted with this newly-found facility on the camera - my only regret being that it took me a year to find it! I suspect that there are people out there that are astounded by my ineptitude - I'll use my age, and the many distractions I have had over the past twelve months as my excuse!
