3D Printed GoPro Filter Adapter

If you have a GoPro camera, you may wonder if filters normally used with DSLR cameras could be used with it. The good news is that yes, you can, and if you have access to a 3D printer, a handy adapter can be printed for this purpose. This adapter was originally seen on Reddit, and you can get the print file here if you’d like to make one. It’s designed for 52mm filters, but the design should be able to be modified for whatever size you need.

I’ve actually done something similar to this 3D Printed GoPro Filter Adapter, instead cutting out of wood using a CNC router. You can see my results, as well as video of it in action here.

Alternatively, if you don’t have access to “exotic tools,” you can simply buy a GoPro filter kit with three lenses from Amazon for just under $12 (as of this writing). This is certainly the easiest option, although possibly not as fun!

An Inexpensive Fisheye and Macro Lens Adapter

fisheye and macro lens adapter on a Canon T2i 58mm lensI recently mentioned a technique for making a fisheye adapter out of a pair of glasses, but considering you can simply buy one for $12 on Amazon, sacrificing a pair of glasses might not be the smartest thing.  The model I bought can also be used as a macro lens adapter, which I was extremely impressed with, and discuss later in the article.

Fisheye Lens:

My first impression of this is that for the price, it seems like an incredibly well-built piece of kit.  It comes with a bag, and screws onto a 58mm lens just like a filter would.  You can use it in conjunction with your normal filters, and autofocus should work in both modes.

No fisheye adapter on the left, versus fisheye adapter on the right

As for how effective it is, the photo above shows a comparison of the stock 18-55mm lens that came with my Canon T2i on the left to (roughly) the same zoom settings on the right.  As you can see, it is zoomed out more, but there are some small black spots in the corners.  This can be eliminated when not zoomed out, but if you’re not zoomed out most of the way, your wide angle is sacrificed somewhat.  Read on for a more extreme example of this effect and a discussion about the included macro adapter: Continue reading

A DSLR to GoPro Lens Filter Adapter

If you have a DSLR camera, you may use polarization, UV, and other filters to give you the photographic effect that you want.  There are some lens filters available specifically for a GoPro camera (see these on Amazon), but what if you want to use DSLR lens filters with your GoPro?

An extremely simple GoPro lens filter adapter

My first, and simplest lens filter adapter is show above.  I simply took one of these step up ring adapters and found the correct configuration to fit my 62 mm lens to hang off of my GoPro.

This configuration worked OK, as seen in the time-lapse video below, but I eventually came up with something potentially much better.  Read on for the rest of the details. Continue reading
