OKKO Magnetic Filters Review
I recently did a deep dive into image quality of magnetic filters, and one brand came out a clear winner. I like the OKKO gear so much, I can't see myself switching to any other brand now. Here's why they work for me.

The Photography Blog

Two essential things you need to know about the OKKO gear. First, they have a no questions asked lifetime replacement policy which means even if you drop and break the filter, OKKO will replace it for you. That’s kind of a big deal. Second, they sell each magnetic component separately. You need to buy a magnetic ring to mount your ND or CPL or cap onto. The Clear UV filter is also a magnetic base, if you don’t want an empty ring in the mix. Then you add a magnetic version of the ND or CPL or cap. Each item is sold separately.

I can see the wisdom of this, having bought a several different brands of magnetic filters for testing, and am now in possession of roughly 12 magnetic base rings for my 77mm threads. If you’re starting fresh with magnetic filters it’s important to make sure you order a base ring (or the clear UV) for the OKKO in addition to whatever filter you intend to snap on later. In my testing the ND64 and lens cap from OKKO also played nicely with all the K&F base filters. They are similar in look and finish, although some clear differences in design are evident. Kase inner rings also work, but not the regular adapter rings.

Your standard lens caps will play nice with the OKKO Clear UV magnetic base ring, thanks to it’s depth and inclusion of an inner lip for the caps to grip onto, but there is no thread for stacking conventional filters. It’s designed for magnetic only. K&F and Kase magnetic filters snapped onto this OKKO Clear UV base just fine, in case you’ve already got some of those on your shelf.

I also tested the 77mm OKKO filters on my Freewell 67-77mm magnetic adaptor, and while the cap fits nice and snug due it’s threaded design, the ND64 magnetic from OKKO doesn’t sit flush on the Freewell. The same scenario was true for the Kase in-laid magnetic rings and the OKKO; those rings essentially sneak the magnetic ring inside the existing filter thread, and it’s the filter thread itself that the OKKO magnetics are not designed around.

Every OKKO filter, base ring or cap you buy comes with a cleaning cloth. It’s a small detail, but you can never have too many of these. OKKO put a little branding on one side of the cloth, so I can quickly tell which side is the “clean” side, and which is the side I repeatedly paw with my grimy fingers.

The most important factor for magnetic ND filters however is image quality. Colour shifts on ND filters is something that really causes me issues when shooting video, and just makes life harder than it needs to be with stills. Some things you can correct easy enough, some you can’t. This review is part of a wider set of tests I ran on the Kase, K&F and OKKO magnetic filters, and from my slightly scientific testing (using an X-rite colour checker and a standardised studio setup) the OKKO was a clear winner. When compared to one of my favie Variable ND filters it was even more impressive.

In my testing the primaries showed little or no shift, except for the yellow channel with a tiny 2% burn. That’s easy to correct, if you even notice the shift in the first place. The bigger test for me takes place outside of the studio though. In the real world I find myself shooting not in perfect clean daylight, but instead I am drawn to the rough edges where the sun is low across the horizon or throwing sunset colours straight down the lens. I like the messy stuff, but filters often do not.

After two weeks shooting with the OKKO filters on the Kimberley Coast I was super happy. I reached a point fairly quickly where I didn't want to risk shooting with the other filters I had brought with me. A had a little pouch full of other filters, but once you find something you're happy with, and can see the footage is coming out clean, you wanna stick with that.

Between the excellent results on colour accuracy, the practical aspects of their design, and the lifetime backup the OKKO brand comes out a clear winner in my testing.

SD Cards Explained

Shopping for an SD card is frustratingly hard, with so many brands, standards and price points to navigate through. Especially when speed is a necessity rather than a luxury. It's also possible that the best value SD card is a MicroSD card, if you have the right adaptor.

Tamron 35-150mm F/2-2.8 Di III VXD

I travelled in the Himalayas for a few months in late 2023 with this lovely lens. If you're interested in more than just tech specs, and what it's like to work with this lens for an extended time then you've come to the right place.

20mm is the new 24mm

20mm is now far more common than ever for both primes and zooms, but is 18mm the better option for photographers? And why even bother with 24mm? When shooting wider than wide does it make a difference to buy an extra few mm of perspective?

Tamron Got It Covered

The Tamron 20-40mm F2.8 and 35-150mm F2-2.8 narrow the gap between primes and zoom. I didn't think I'd like these new lenses from Tamron so much, but the fact is every time I took them out to shoot I ended up with a tonne of great images. That’s a little bit annoying for a prime lens snob like myself.

My Favie Magnetic Filter

From the studio to the harsh sunlight of Australia's North-West, I dragged my little pouch of magnetic ND filters around the country to find out which system works best. And found myself a new best friend in OKKO.

SIGMA 60-600mm Field Review

I spent a few weeks in The Outback with the new SIGMA 60-600mm F4.5-6.3 DG DN OS SPORT L-Mount. The name is a mouthful, and the lens is a handful. This super telephoto represents the latest in AF and OS technology from Sigma, packaged into a superbly flexible and optically impressive full-frame wildlife lens. Available for both L-Mount and E-Mount.
