The 3.37mm is our newest 4K lens designed for the GoPro® HERO® 4/3, DJI Phantom 4/3, DJI Inspire X3 and Yuneec Typhoon H CGO3+ camera lines. With its 87 degree HFOV 16MP sharp 7 glass (4G+3MO) non-fisheye optics this lens captures the entire image sensor.
[Summary]
Compared to our popular 3.97mm lens, the 3.37mm is a little wider field of view and has better edge sharpness. The flare is a little more concentrated into points instead of spread out like with the 3.97mm. The 3.37mm also has a shorter TTL, so it sticks out of the camera less. This means you can use it in the GoPro® HERO® 4/3 waterproof housing and the focus will not change.
After removing the stock lens the 3.37mm threads in easily. No need to change to a different lens mount and all GoPro®, DJI and Yuneec accessories that mount around the lens surround are supported. No gap is present between the lens and the black GoPro® lens surround as the 3.37mm lens spans the entire cavity. On the DJI cameras a small gap will be created as the lens is not as large in diameter as the stock lens, so we recommend using the original glass lens protector to keep debris out. On the Yuneec CGO3+ camera the stock lens is the same diameter so no gap or modifications to the lens surround is required with the 3.37mm lens installed.
On the GoPro® HERO®, we recommend using an ND4 filter (or higher) with ISO400 for full sun shooting. On the Yuneec Typhoon H we recommend keeping shutter speeds at 1/500s or slower to reduce jello from the rolling shutter during full sun shooting. If the slower shutter speeds are too bright you can add ND filters to stop down the light.
With the same f-stop as the stock lens on the GoPro®, DJI and Yuneec cameras the capture software will never know the lens has been changed. Light levels will be handled as normal and depth of field will be very similar.
With it being 36 degrees narrower than the stock GoPro® lens, 3 degrees narrower than the DJI Inspire X3 and Phantom 4/3 cameras and 11 degrees narrower than the Yuneec H CGO3+ camera, this lens brings your subjects closer without being too zoomed in to introduce unwanted image jitter.
| When you change the lens on the GoPro® HERO® cameras we recommend having us remove the stock lens profile software so the colors are natural (and not tinted pink around the edges). All GoPro example media shown has this lens profile removed from the camera. |

I love them
Size: 12-18 Months Toddler, Color: Under the Stars Camping Blue Leather
The absolute cutest shoes ever. I will be keeping them forever. The size is perfect, they’re very lightweight, and perfect for indoor outings like the library. They seem pretty comfortable, my son enjoys putting them on.

Hard to put on but easy to come off
Size: 12-18 Months Toddler, Color: Sebastian Shark Blue
As the title says, the shoes were a bit hard to put on and perhaps that was because we were doing it for the first time . However, they would come off super easily and so we lost one of the shoes the second time the baby wore them. That was a bummer as they aren't particularly inexpensive. We didn't really get to try them out as much as we'd have liked but based on what we saw, they looked comfortable and durable. Baby loved the shark design.

Held up for well for 5 months. Fit my son’s chubby feet like no other shoe.
My son has been wearing this shoe since he was 9 months old and was cruising furniture. I bought the 6-12 month size. He started walking at 10 months and is 14 months now. He’s still wearing this shoe and it has held up well. I have him barefoot in the house and mostly use it for when he’s in the back yard, at the gym childcare and when we are out and about. He wears shoes for several hours a day at least, though I bought the Robeez sandals at the start of summer and have been switching between the two pairs. My son has wide feet and doesn’t really fit in anything but soft sole shoes. His feet are about 5” long now and these shoes are getting too small. It’s almost time to size up! They’ve treated us well. Plus they are super cute and match every outfit. He giggles when I put them on.

Cute, different, and good quality
I had these for my kids when they were little. I am now buying them for my first grandchild. They appear to be the same good quality they were years ago. I highly recommend : )

Great shoes for the little one taking his/her first steps
Great shoes for the little one taking his/her first steps!! I actually ordered 2 pairs, one for my son in the 12-18 months (even tho he was 10 months old) and a 6-12 month for a friend. The 6-12 month fit my son perfect!! (my son was in a size 5) but I knew they would only last a few weeks so I kept the 12-18 month ones and he started wearing them. He seemed to like them, never tried taking them off and they were easier to walk in than socks but for some reason the top of the foot area is HUGE! They stayed on no problem but lots of wiggle room in the top... He is now running and wears shoes with a thicker sole for the rocks but we still love these for inside when it is too cold to go barefoot. I would say the 12-18 month fit like an average size 6.
