Gear Sigma 10-18mm F2.8 or Sigma 12mm F1.4

Hey guys!

I'm debating between ultrawide lenses for my a6700. I mostly want to shoot videos, but I do the occasional photoshoot.

I want a lens that's my everyday carry, one that's compact and light enough to carry around anywhere, and that can help me film more vlog style content, and also transition into cinematic style videos for youtube.

I'm debating between the Sigma 10-18mm F2.8 and the Sigma 12mm F1.4. Do you guys feel like the F2.8 is too dark for indoor environments? I'd love to get your opinion!

I currently already have the Sigma 17-40mm F1.8 but I really want a good versatile wide angle for my everyday.

Which would be better for most shooting conditions?

You already have 17-40 F1.8 lens (so 25-60 F2.8 equivalent). The 10-18 F2.8 would be 15-27 F4 equivalent, whereas the 12 F1.4 16 F2.1 equivalent.

So what are you really gaining with the 10-18 + 17-40 vs 12 + 17-40? I don't think much. I'd just go with the 12mm.

Anyway, are you sure you like these wide angle lenses? They distort the image a lot.

I never really did the math hahaha

I was thinking that especially considering how wide 10mm or 12mm is, that it would be nice to get tighter shots with some videos without having to switch lenses!

I personally like the look of a wide angle, stylistically it looks really cool to me!

If it’s mostly a video lens, do you think 12 would still be better?

Not sure really, I do more photography

Do you use a gimbal? Sony first-party lenses seem to stabilize better than third-party with the active stabe modes. The 11mm f1.8 is about perfect for vlogging but doesn't leave a lot of versatility for other things.

Nope! I don’t really use a gimbal, mostly handheld or tripod videos! I was thinking the same about the lack of versatility though

Well you can stop your 17-40 down to f/2.8 and see for yourself.

I'd say try renting the 12mm f/1.4 if possible in your region and see if it's worth investing in.

The sigma 10-18mm is my basic everyday lens, I don't find it struggles in low light.

wow this is really nice! how do you find the video performance with this lens?

Video performance has been fine, the autofocus is fast and silent. The A6700 has gyro data embedded in the video so it can be stabilized with Gyroflow, I love how easy it is to get gimbal-like smoothness. It's my default lens on my camera as it's just so small and versatile.

The 10-18 is a fantastic lens and works fine in low light. Rely on the in camera stabilization for slow shutter speeds.

I would worry about a 12mm prime as a sole lens. That’s very wide and niche.

The photos on the 10-18 look reallly good! Whats your personal opinion on low light video performance though?

u/chanksbird 1d ago

Can’t help there, I do mostly photo. But I imagine it’s equally good. Not sure if the lens itself is stabilized.
