As a fellow Sony shooter, I can share my experience. I started with on-camera flash but quickly moved to off-camera for most situations. Here's my take:

On-camera flash:

• Easy to use, always with you
• Good for run-and-gun event photography

• Can produce harsh, flat lighting
• Limited creative control

Off-camera flash:

• Much more flattering light, especially for portraits
• Greater creative control over lighting
• Can create depth and dimension in your images

• Requires more setup time
• More gear to carry around

For portraits, I'd definitely recommend off-camera flash. For events, a mix of both can be useful. As for specific models, I've had great results with the Godox V1 for Sony. It works well both on and off-camera, and the round head produces nice, soft light.

Jumping in here to add a bit more technical weight to the discussion. @Reply #3 - good point! That model is popular but before we get ahead of ourselves, what kind of ambient light are you usually fighting? Knowing if you're trying to overpower midday sun or just fill shadows in a dim hall changes everything about the wattage and recycle times you'll actually need. In my experience, everyone talks about the light quality but ignores the hardware stress. A few things you really gotta watch out for:

• Weight distribution on that Sony Multi Interface shoe. It's fragile compared to older mechanical mounts. Hanging a heavy unit off it while running around is a recipe for a cracked mount or bent pins if you catch it on something.
• Thermal throttling. If you're shooting high-speed sync at high shutter speeds, your head is gonna get hot fast. Some systems will trigger a lockdown after just 15 or 20 full-power pops to protect the electronics.
• Recycling lag. If your shooting style involves bursts, an on-camera unit without an external battery pack wont keep up with the a7iv's frame rate, leading to black frames. I've tried many setups over the years and honestly, the biggest mistake is choosing based on convenience instead of the actual duty cycle. Let me know your typical environment and I can give you a better breakdown of what wont fail on you mid-shoot.

Saw this and it took me back to my first big gig with the a7iv. I was so worried about recycle speeds and burst performance that I over-prepped my bag with like six different triggers. Actually reminds me of a shoot I did at this old heritage hotel downtown. The architecture was stunning but they had these ancient elevators that kept getting stuck. I ended up taking the stairs with all my gear and nearly passed out from the heat.

• the hotel bar had the best ginger ale ever
• elevator guy said the place was haunted by a bellhop
• met a guy there who claimed he invented the selfie stick The stairs were all narrow marble and I was terrified of dropping my bag. Thinking back, I spent more time worrying about the ghosts than the actual lighting that day. My bad, totally lost my train of thought lol.

Just caught up on this thread. ^ This. Also, you guys are right about Godox being the value king, but I'm always a bit paranoid about the Sony hot shoe. Those pins are tiny and easy to bend if you're not careful. Basically, everyone is saying on-camera for speed and off-camera for looks. If you want to keep things reliable and stay satisfied with your gear long-term, I've had good luck with these:

• Godox X2T-S TTL Wireless Flash Trigger
• Sony HVL-F46RM Wireless Radio Flash I usually stick to the native Sony flashes for paid gigs just to be safe, tho Godox is great for personal stuff. Been using that F46RM for a while and honestly, no complaints so far... it just works every time without stressing the mount.

Both are OK, and I suggest you get the Godox flashes, they offer both great on or off camera flashes.

When deciding between on-camera and off-camera flash for your Sony camera, consider the following:

1. On-Camera Flash: Convenient for quick shots and portability. Ideal for bounce lighting in small spaces.
2. Off-Camera Flash: Offers more creative control and flexibility, especially for product or macro photography. It allows for better positioning and lighting effects.

If you choose off-camera, ensure compatibility with your flash system, as many brands have exclusive triggers.

I love Godox V1.

For Sony a7iv, on-camera flash is convenient for quick snapshots, but off-camera offers more creative lighting control for portraits and events. Godox V1 (on) and AD200 (off) are popular choices. Consider your budget and desired level of control.

On camera flash is more easy to use.
