The 3.97mm is our newest 4K lens designed for the GoPro® HERO® and DJI Phantom/X3 camera lines. With its 16MP sharp 8 glass non-fisheye optics this lens captures the entire image sensor.
This model of the 3.97mm lens has our Blue 450nm filter cemented to the back of it. The blue channel of the image will contain the Blue light.
After removing the stock lens the 3.97mm threads in easily. No need to change to a different lens mount and all GoPro® and DJI accessories that mount around the lens surround are supported. No gap is present between the lens and the black GoPro® lens surround as the 3.97mm 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.
No fisheye/barrel distortion means objects are naturally straight and just as your eyes see the world. Mounting to a UAV? You'll be glad to know that's exactly where we mounted this lens the most as we were tweaking its production. See the videos below for examples mounted to the 3DR SOLO.
With the same f-stop as the stock lens on the GoPro® and DJI 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 over 40 degrees narrower than the stock GoPro® lens and 8 degrees narrower than the DJI Inspire X3 and Phantom 4/3 cameras, this lens brings your subjects closer without being too zoomed in to introduce unwanted image jitter.
If you've thought of changing the lens on your camera but were never happy with the way the lenses on the market handled lens flare, you'll be glad to know that was a major concern of ours during development. We went through many iterations to reduce any "bad", concentrated flare spots and left only minimal cinematic flare. See the "Sunset at Scripps Pier" video below for an example.
| 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 example media shown has this lens profile removed from the camera. |

Pack's Promise was okay but not great
Format: Kindle
Pack's Promise was okay but not great. I won't recommend it to anyone that I know.
PRO:
* Very likable characters
* Lots of steamy scenes that are written very well
* The spelling and grammar are good
* The punctuation is good with the exception of using hyphens instead of commas. Lots of hyphens. Lots and lots of hyphens.
CON:
* Almost no interactions with any characters outside of Madison and the pack
* Nearly no plot. They meet, get together for a heat, agree to make it permanent, done
* Quite a few typos such as extraneous words, missing words and words out of order
THINGS TO KNOW:
* More steamy scenes than storytelling
* A lot of MM & MMM, some MFMM during heat

Fluffy and Nice Omegaverse
Format: Kindle
… this would have made 5 stars but for 2 reasons.
A.) there were quite a few typos; misspelled words, missing quotations, “the his” mistakes, and various signs that maybe a proofread would do good.
B.) the writing was quite textbook. Late blooming omega is struggling with her new self, finds a absurdly wealthy pack of alphas, every thing is almost insta-love but she resists, then decides to love herself and let everyone be happy.
Rian was my favourite (obviously the author’s favourite too because he got the most page time) but I wish we could see more of his CEO side? He went to work maybe ONCE the entire time. Gray was supposed to be the “growly one” but he turned out to be puppy dog. Lucas was a genius brainiac doctor - but also super alpha with an aggressive hindbrain with a breeding k*nk?? And then there was no actual “breeding”??
Spice 3/5 - normally omegaverse books are super high on messy smut but this was tamer.
Romance 3/5 - insta-love that was then resisted because of personal hangup’s
Plot 2/5 - weird paced head hopping, showing the same scene from different POV’s that made me feel like it was 2 steps backward, 1 step forward.
Humour 4/5 - there were a dozen lines that genuinely made me chuckle out loud
Would have been five stars but the lack of proofreading and the predictable plot made me unable to get up to ADORED IT level - four stars is still and official ENJOYED IT, y’all. This isn’t a bad rating. The “Club Heat” has intriguing possibilities so I’m going to give the second one a shot.

Fun with a late blooming omega
Format: Kindle
I like this book. The story is fun, cute, and sexy. There's just a little drama, some excellent, steamy scenes, and a fairly good relationship building storyline. I especially like how all the main characters are a bit older than the usual 20 somethings I tend to see in this kind of book.
Having said that, I wish there were more descriptions of the places, as well as the food in the fancy restaurant. I enjoyed the cocktails at the club, so I missed that kind of detail when Gray took Madison on a dinner date. I also wish there had been more interaction between Lucas and Madison, and Lucas and Rian. It felt a bit lopsided, with a focus on Rian, Madison, and Gray.
I wish it had been proofread - there are a lot of typos, but nothing too distracting.
