As far as I know and care, equipment is NOT the most important for any photographer. The image itself and the story it’s telling is the main issue.
To me it’s certainly more important to know the camera you carry and use, than to long after bigger, better and more expensive gear. That said, here are my three options today:
1. My cell phone, an iPhone 12. Not the largest sensor in it, but capable to take decent pictures, when the light is good enough. Sometimes a pic from your mobile is all you need. And I always carry it.
2. My full format Canon R5. Full format because I rarely use a flash. And I can push my ISO way up and still get great pics on occasions when I lack light. I mainly use my 24 – 70 mm 1:2,8 with it or the recent 16-35 mm 2:8.
3. I do have a compact Fujifilm X100T. A camera I’m not that comfortable with. Not quite pleased with what I get yet, even though I really like the small size and noiseless effort with it.
For postproduction I use both Photoshop and Lightroom, depending on what mood I’m in.
