I’ve shot air shows using my EF100-400 mkii handheld, with and without a 1.4iii extender mounted on my EOS 1DXII and have always left the IS on. Never encountered any problems with leaving it on, more important to have the camera setup correctly.

I seem to recall that the Canon utilities have had a software update since Catalina was issued which I downloaded and have not experienced any problems. I have got into the habit of connecting my Canon cameras to my iMac to download images and the utility opens with no problem at all.

You can also program the Af on button and * button to settings different to those that you may have set up when using the shutter button to focus. That is shutter speed, aperture etc.

I have an old Wacom Intuos tablet, which as you say, is no longer supported by Wacom. This doesn’t however stop it working for me, other than you can’t resize the working area under the preferences. There may be other attributes which no longer work but the pen still works ok.

New Canon software is out. Latest Canon DPP and Canon Utilities compatible with Catalina.

I think Linda, if she doesn’t mind me saying so, meant thumb knuckle smears on the lens of the glasses she wears.

I think most people will charge a battery ready for going out however I think all this talk about damaging a battery if you let it completely discharge is a load of guff.
All the 1D series cameras right up to the latest 1DX mkiii have a calibration setting which is indicated on the back of the camera screen telling you to calibrate the camera battery the next time you charge it. This facility on the charger completely discharges the battery before recharging it. The point of this exercise is to reset the battery charge information on the camera battery menu to the actual charge condition of the battery.
Ok this is not available on other Canon series cameras but the batteries are all lithium ion irrespective of the model.

It’s telling you the batteries are starting to fail, that’s the point of having battery info on the camera. It’s a fairly simple piece of information to tell you the condition of the batteries.

The wildlife in Scotland is wild. Even your 300 will be too little, so don’t expect to much. I use a 100-400 with a 1.4 extender on my full frame and even then I pack my 500 and use that with the extender. Hope you have a great trip, you’ll enjoy it although it’s a long drive up from London.

Photographing the man in the moon can be a bit of a fools errand. Look at the pictures posted here and ask yourself ‘is this up close and personal’ enough for me. The next lens up, like the the next camera body up in the range will always offer something and most of the time a lot better than what you’ve got. You can take pictures with a $12000 super telephoto and get something that will leave all the pictures posted way, way behind and then some bugger will come along with a telescope attached to their camera and leave your pictures way, way behind. Look at what’s been posted and if that’s what would satisfy you then buy the lens that goes with it but don’t go selling the farm for it, it’s too early to be that serious.

I spent 10 weeks cruising around South America this time last year starting from the Uk and taking with me a 1DXII and a 5Dmkiv together with a range of lenses and a number of memory cards. I was concerned like you about storage and took my basic 2017 MacBook Pro with me loaded with Photoshop CC. I wasn’t worried about hard disk storage (256gb) because I took a couple of Sandisk 500gb SSD’s. This is a really lightweight and portable setup which allowed me to download daily to the SSD’s and to use the MacBook for processing pictures if I was so inclined. This worked with no problem at all other than on a couple of occasions, having to log in to Adobe to verify my Photoshop subscription. Absolutely recommend this to you.

You can see from the comments why, when talking about named software running on your computer you should say what it is and what it’s running on. That’s why half the comments have no relation to your question.

I went on a printer workshop at a paper supplier. They were using an Epson printer and showed how to set it up, profiling etc with Photoshop controlling the printer. When it came to black and white printing however the printer was set to controlling the printing in Photoshop.

Having shot with a 1DXII and a 5Div you have obviously gone for the two cameras in the Canon setup to give you real quality pictures. Like you I shoot with the same cameras but to be honest the 5Div only comes out when the 1DXII would be out of place.
All the people piping up about how wonderful their camera bodies are have obviously never used a top end camera like the 1DXII or the Nikon equivalent. I too am looking to go to a lighter weight setup and that means mirrorless.
The outstanding mirrorless cameras are in my opinion made by Sony and as someone who shoots mainly wildlife it is the Sony a9 or now the a9ii that stands out although the a7Riv with its huge megapixels is in the race too. Coupled with the 200-600 lens it produce amazing pictures if you don’t wish to spend mega bucks on the 600 Prime.
