Replacing the GoPro Hero Lens

[kweeni]

Hello!

I was wondering what you guys think of replacing the GoPro fisheye lens with a different one.

Has anybody attempted to try this? If yes then I'm wondering how the results are and if you thought it was worth it or not.

Example lens: https://www.amazon.com/5-4mm-Megapi...31330&sr=1-3&keywords=gopro+hero+4+5.4mm&th=1

Some video example I found:

Yes it's possible and recommended if you want better overall footage. There's many discussions on here. Try using search. 'Gopro lens' 'peau lens' etc. I'm actually waiting on my cheap Chinese lens to come in. Peau is pricey but some say it's better.

What brand is that lens you're looking at? I couldn't find the name. I swear I've seen that same exact lens somewhere on the Internet for like 20 bucks. For a few dollars more you could get the Peau.

Which chinese one did you find actually? I was just on Peau's website and would definitely buy it if it was on sale but.. it's not so it's $140. A little over my budget.

I did also find this: 4K LENS 3.97mm f/2.8 82d HFOV 16MP Gopro Lens(Flat)

Edit: found a Chinese one here for $25: Buy Products Online from China Wholesalers at Aliexpress.com

This is the lens I put in my GP 4 black. Works very well. Getting it properly focused was a bit challenging but got it after a few attempts.

Does that lens have this problem?

I checked sample videos and this looks great! I ordered it.

I'm not sure if it had the pink corner issue. I'll have to wait till it comes in to test it

By the way, how did the installation go for you?

The pink cast isn't an optical problem, it is a lens calibration profile problem. The GoPro firmware has a color calibration baked in that adjusts for the color cast of the wide-angle stock lens. When you change the lens, you get a color cast in the corner as this calibration is correcting for a color change across the glass that isn't occurring. Peau offers the lens profile service to rectify this issue.

If you primarily want to shoot B&W, it doesn't matter much if at all, and you always have the option to correct for this in post-processing manually yourself.

What's B&W?

 

[Saijin_Naib]

What's B&W?

Black & White, like the attached image.

 

[kweeni]

Black & White, like the attached image.

Oh, well I don't do any black and white. If I have a red corner, I can easily fix this post in a software like adobe premiere?

Fix yes, easily, depends how familiar you are with this type of post-process work. You likely will have to make your own color-correction overlay image. Not rocket science, but it can be a bit fiddly.

Just pay the money to Peau for the color correction download and the camera will be good for any aftermarket rectilinear lens. I see it as just part of the cost of modifying the Gopro.

True, but if you have multiple GPH4B, it's very costly. I wish the $50 at Peau was a one time cost.
This why I haven't done it yet. The only time I get pink is in the panorama's stitching. That's where Photo Shop earns it's money.
