Frii Trilens REVIEW Carry Three Lenses at Once | Mac Sources

Frii Trilens


Leave the backpack at home the Trilens keeps you with the right lens

I have an issue when it comes to taking photos. I always want to travel with ALL my gear. I end up taking lots of stuff but never using half of it because I hate getting in and out of my backpack. Because of this, I sometimes end up missing some cool shots since I don’t have lenses in an easily accessible location. Enter the Trilens by Frii Designs. This is a device that allows you to hold up to three lenses on your belt like a holster. The Trilens keeps me using the right lens for the job without needing to fumble through my bag. And, as an added bonus, I sort of feel like a cowboy reaching for a sidearm when I use it.


The Trilens is made from high-quality elements (high-strength steel, fiber reinforced nylon) and is heavy-duty. It’s built to be weather resistant and can hold loads up to 220lbs. The device slides onto any belt and the auto-friction mechanism keeps the Trilens stable while you move. In the package, you get 1 x Trilens beltclip, 1 x Trilens housing, 1 x felt bag, 5 x sets of cap magnets, and 3 x protection caps.

The set-up of the Trilens is very minimal. There is no assembly required other than attaching the belt clip. The Trilens comes with magnetic arcs that are designed to keep your lens caps safe and magnetically snapped to the empty slots on the Trilens housing while the lens is in use. This was an invaluable accessory to me as I tested this product out. I hate having to place lens caps in and out of my pockets. Keeping the caps on the housing of the Trilens is much more practical. Plus, the lens cap keeps dirt and debris out of the housing so there is a far less chance that you might end up with dust inside your lens.

Using the Trilens has been an interesting experience for me. I decided to test it out initially by taking it to our local zoo. The zoo is scenic, but very hilly. It’s a decent hike to get from one end to the other so I thought it was the ideal situation for the Trilens. I mounted two lenses onto the housing and placed the third onto my camera. The operation of the Trilens was very fluid. I was able to swap out lenses with little effort and it was a big help to me while I was in the park and moving from environment to environment. As I moved through the zoo, I didn’t have any issues with swapping out the lenses even though they did seem to weigh down the side I was wearing them on.

I think the Trilens has a great build quality and works very well but the weight from my lenses really puts a strain on my belt. I find myself distracted because I was constantly pulling my pants up or in pain because I have tightened my belt way too tight to keep the device from dragging on my side. Having the option to keep three lenses on my side is awesome and for some occasions, it’s going to be the way to go. I think if they would have made this for just two lenses it would have been less stress on my pants and belt.

Even though I had some difficulties with the weight on my belt, the Trilens does manage to keep the lenses secure. I never felt like there was any danger of them becoming loose or falling out of the housing. I really liked how the Trilens manages its center of gravity. The heaviest lens will always dangle at the bottom. So it doesn’t matter what size lens you store on it.


I feel like under the right circumstances and for the right person, the Trilens is a great product to use. It does what it is supposed to even though I felt like the weight in one spot was just a little too much for me. I think the Trilens is an extremely well built product with a unique purpose and design. I can recommend it to photographers but would warn them to be selective about which lenses they store on it.
