Reddit reviews Vicdozia 2.5mm Replacement 170 Degree Wide Angle Camera DV Lens for GoPro HD Hero, Hero 2, SJCAM SJ4000 SJ5000, HS1177 Runcam Swift FPV Cameras

That one on amazon you found looks really bad to be honest. When something breaks you'll have trouble finding a replacement, the radio is proprietary and will never work with anything else, it's got tons of plastic parts, and the battery is probably crap. Even if I'm completely wrong about it and it isn't garbage, there's no way it's worth $450, since you can actually get a pretty decent set up with that much.

There aren't going to be many good full kit options out there. The only one even worth considering is the eachine wizard, and even that is dubious at best. Instead you'll want to buy the radio, goggles, and then a BNF (bind and fly) drone all separately, which means you choose which receiver to put in it (usually when you buy it, you select which one when you add it to your cart and they'll put it in for you), and when you get it you just bind it to your radio.

For a radio, get the Taranis QX7. There are several options to consider, but you really can't go wrong with this, it's worth every penny: https://www.amazon.com/Frsky-Taranis-Transmitter-Racing-Drones/dp/B06XQWQ7C3/ref=sr_1_1?s=toys-and-games&ie=UTF8&qid=1510987554&sr=1-1&keywords=QX7

This is a FRSKY radio, which means when you're buying the drone, just select FRSKY version so you get the right receiver in it.

Check out the channel uavfutures, he reviews a lot of prebuilt stuff, as opposed to other channels which review individual components. He does really clickbaity titles which can be difficult to get through, but check out his playlists as they're a bit better organized.

For goggles, there are so many to consider across a huge price range. The big two "types" are box style vs compact style. Boxes are big and bulky, but also a lot cheaper. Usually under $100. Most compact goggles are way up in the $300-$500 range, but there are a handful like the eachine EV100 and F640 that manage to get that slick form factor in at just over $100. Here's UAVFutures' playlist on them: https://www.youtube.com/playlist?list=PLP0PoGwU8OPYW549moGE6OSj5qNa8vx67, but if you prefer written down with way more detail and comparisons, Oscarliang is a fantastic resource as well: https://oscarliang.com/fpv-goggles-review-fatshark-skyzone/

It's also worth noting, since you asked, that latency is not really going to be an issue as long as you're using fully analog 5.8GHZ, which is going to be basically anything you see on uavfutures. Latency is only a thing on digital, like those shitty wifi cameras that connect to your smartphone. There are a couple digital FPV systems worth using, but they're still very new and thus very expensive.

Field of view is very important. The more you see, the more awareness you have. However that's a property of the camera lens, not the goggles. You can also swap out the lens very easily if you want it wider or different. I personally use this lens which is branded for gopro, but they're all the same.

Field of view in goggles is different, it's the size of the image in front of you. Getting wider field of view in this case won't actually allow you to see more, it'll just be stretched. You don't want to go too small or it'll be hard to see, but you also don't want to go too large or you'll have to move your eyes around the screen to focus on different things. Not too many goggles go outside of either extreme, so you probably won't need to worry about this part.

For the drone itself, again, UAVFutures. He reviews a ton. Just watch through a bunch of them and see which one catches your eye: https://www.youtube.com/playlist?list=PLP0PoGwU8OPaYMlsaWxSg7xr7xZXbxhf1

here is one I found on amazon with a large lens, I know you have to remove the lens on the pi camera but I do not believe the lens would screw directly into the module. I used an adapter because of two reasons, the tutorial i was following did and I wanted to keep pressure off the module because I was using a 175mm telescopic lens and I was worried about the torque pressure. I'll do some more research and either edit the post or reply to you, whichever comes first.

Woops, not sure where it went. Here:

maybe something like this? https://www.amazon.com/Vicdozia-Replacement-Degree-Camera-Cameras/dp/B015EE7G58/

​

or this? https://www.amazon.com/Yohii-Fisheye-Megapixel-BL17820-5MP-Panoramic/dp/B07DJZJD8V/

I got this one https://www.amazon.com/dp/B015EE7G58/ and adjusted the ring on it until it was focused.

Not sure if you screwed the adjustment ring all the way on, screwed the lens all the way in, and then unscrewed the lens and check your goggles until it's focused. Then bring the adjuster ring down until the lens is locked in place, focused.

Same experience, I tried the one below and couldn't get it to focus

edit: It works! I really forcefully cranked it down hard with my fingers and was able to get it to focus
