Tip: Grab the Sony E 11mm f/1.8. I went through this last year and the Sony E 15mm f/1.4 G felt way too tight once you add the 4K60 crop and Active Stabilization. The 11mm maintains a wide, natural field of view even after the software crops in, so ur head isnt filling the whole frame. Its just a better technical fit for handheld stuff. gl!

Just catching up on this thread – good points made about the crop, for sure. But honestly, for vlogging, especially if you're out and about doing walk-and-talks a lot like you said, I'd push back a bit on making focal length the absolute #1 priority. From my experience with gear over the years, the biggest headaches often come from reliability issues down the line with heavy use.

Late to the party but I wanted to add my perspective. @Reply #4 - good point! Durability is something people often overlook until something breaks right in the middle of a shoot. Before I give my full take, I have a quick clarifying question for you. Are you planning to do most of your filming in controlled lighting environments, or are you strictly sticking to outdoor handheld work? Knowing your typical lighting setup helps narrow down the aperture requirements quite a bit. Regarding brands, here are my thoughts on the general directions you could take:

• Sony native glass is basically the gold standard for autofocus reliability. I have been using their lenses for a long time and they just work well without any complaints.
• Sigma is another brand where you really cant go wrong. Their build quality is consistently excellent and they feel very professional in the hand.
• Tamron offers some solid alternatives that are very reliable for travel and everyday vlogging. Basically, if you stick with any of those major brands, you are going to get a high-quality experience. I am personally very satisfied with the results I get from third-party manufacturers these days because the quality gap has basically closed. If you want the safest path, stick to the main brands and you wont have any issues with that new body.

The Viltrox AF 13mm f/1.4 Sony E is a solid bet for long-term use. Its built with a metal chassis that handles bumps better than the plastic Sony primes. At 13mm, it sits right in that sweet spot where the 4K crop still looks wide and natural without the fisheye look. If you vlog outside a lot, the Samyang AF 12mm f/2.0 E is a decent option too. It has weather sealing which keeps dust and moisture out of the internals. Its simple, reliable, and the autofocus holds up fine for tracking faces while you walk. Both lenses offer better value and durability for the price imo.

In my experience, you definitely wanna go with the 11mm for those handheld walk-and-talks. I've spent years dealin' with Sony's crop factors, and it can be a real pain if ur not careful. - The 4K crop factor: Seriously, once you turn on active stabilization on that body, the crop is pretty intense. The 11mm gives you that extra breathing room so your head isnt just a giant bobblehead filling the frame... it looks way more natural.
- Arm fatigue: I mean, holding a camera at arm's length gets old fast. The wider lens means you dont have to stretch ur arm out as far to get a good shot. - Low light: The f/1.8 is still plenty fast for most stuff, honestly. Be careful with the 15mm—it’s a beautiful lens, but for vlogging, you might find it feels way too tight once the digital stabilization kicks in. I would suggest the wider one cuz it's way more forgiving when you're on the move. gl!

Been using this for years, no complaints
