The new released Sony a9 III is another great camera for professional shooting.

For professional photography, I highly recommend the Sony a7R V. Key benefits:

• Extremely high resolution 61MP full-frame sensor for incredibly detailed images
• Fast and accurate autofocus with real-time eye AF
• In-body 5-axis image stabilization for sharper handheld shots
• 4K video recording and pro-level video features
• Durable weather-sealed body

The a7R V is an all-around workhorse that excels for studio, landscape, portrait and event photography. The high resolution and pro features make it an ideal choice for serious photographers.

If your work demands the utmost in detail and resolution, then the Sony A7R V is the undisputed king. With its 61MP full-frame sensor, this camera is a dream for landscape, studio, and portrait photographers who need to produce large prints or have the flexibility to crop significantly without losing quality. 

The AI-powered autofocus is a significant upgrade, with impressive subject recognition that locks onto eyes, animals, and even vehicles with incredible accuracy. While it might be overkill for some, for those who are obsessed with detail, the A7R V is in a class of its own. It's a powerhouse for anyone whose career depends on delivering the highest resolution images.

Sony a9 III or Sony a1

Just wanted to say thanks for everyone chiming in. Super helpful discussion.

Depends on your budget, if budget is not problem, get the Sony a1.

Waiting for Sony a1 II.

I think in 2024, Sony a1 is a bit outdated, just waiting for Sony a1 Mark II.

Sony a1 Mark II now released, get it now: https://bhpho.to/40Gs0yN
