I now had the EOS R mirrorless camera and Sigma Sports 60-600mm lens back, and was keen to set everything up again, and also having learned from Canon how to shoot sequences with breaks in shooting, without the interruption of the saved files in the viewfinder until I needed to review the captured images. I did not find it as fluid as when using a conventional DSLR, but with practice I believe I will manage to master it. When you learn how to set this up, it is straightforward, but I had to find the setting by asking my Canon Guru!
Now if I need to review the image I click Preview rather than have to wait as the sequence is displayed in the viewfinder, when what I was trying to do was continue shooting once an action continued. Thus far it is not as fluid as my earlier experience with a mirror flipping, but I am hoping I will master it with more practice. One piece of advice offered was to slow the frame rate, but that would seem counter-intuitive, but I will explore all this as every opportunity arrives. What I have already found is that the quality of the captured images exceeds that of the earlier lenses due to the reduced camera shutter vibration and the larger inherent file size; in other words the image quality exceeds what I previously achieved. Another factor also comes into play in low light levels; the image brightness improves both the cameras ability and mine to focus accurately.
The adapter to use my existing investment in lenses is yet another benefit of the move to a mirrorless body, but it has been a steep learning curve, and as yet I do not have the fluidity I experienced with my earlier bodies (and my brain is older, and less tractable!) My own body has a similar issue with my wonderfully stable Benbo tripod, whose weight is a severe issue when travelling on foot for any distance!
On this trip the only bird that was in any way special was a lone Grebe, but the trip was mainly an exercise to gain confidence in the mirrorless body and the Sigma 60-600mm lens, which I fulfilled albeit not spotting the incorrect setting of colour temperature, which fortunately I was able to sort in ‘post’! I still have further settings to reinstate, but for anyone considering the change to the EOS R, fear not.
