Those are wonderful photos -- love those kangaroo paws flowers! Very cool, capturing the birds in there! In Oz, you have such interesting flora and fauna!
The duck orchids are intriguing -- and I can definitely see why they are called that! Definitely looks like a duck!
I envy you with being in summertime right now as here winter is approaching and we're having a chillier November than we usually do, which makes it less pleasant to go out shooting. We have a lovely botanical gardens not too far from where I live and in the spring and summer it's a real delight; even in early fall there are plenty of things to shoot, but now, heading into winter the main place for shooting flowers and plants is in their indoor atrium area.
Focus stacking is one thing I've never attempted, although I've seen comments about the process and the results of the process -- really makes a difference when shooting macro!
I've been waffling and waffling for over a year now trying to make up my mind about what I want to do and have watched and waited, read others' comments, seen various images from various cameras, etc. Ever since I purchased my Sony NEX-7 several years ago I have really liked mirrorless and knew that I probably would not buy another DSLR, that whatever I chose next would be mirrorless and preferably full-frame. About a year and a half ago I started really thinking about getting a new camera, and then of course Nikon announced and eventually released the Z series and I thought, "well, let's watch and see how this goes...." and Sony announced and released the A7III, which had stellar reviews, and then I became more interested in the A7RIII, and just about the time I was settling on the idea of getting one of those, Sony released the A7R IV! Time to get moving with whatever I am going to do, I've been dawdling long enough now!
A photographer friend here in my area and I went out shooting together a few months ago and he had just recently gotten the new Canon R something-or-other, his first mirrorless, and he is very pleased with it. He's been a Canon shooter for a long time. I'm not sure if he needs to use adapters with his earlier lenses but the day we were shooting he had a couple of native R lenses, one a medium-range one and the other one a longer lens.
I agree with you about portraiture -- that's not something which interests me much, either, although I do enjoy occasionally capturing candids when people are having fun and not aware of the camera, not deliberately posing. Macro (flowers, objects, etc.) and birds (especially water birds) are my favorite things to shoot. It drives me wild when I'm out shooting and the day is windy so that just as I'm about the press the shutter button, my subject suddenly gets blown by the breeze! Frustrating! Even a fast shutter speed may not be enough to stop the motion.
Enjoy your new Lensbaby and I'm looking forward to seeing more from that unique lens!
