Switching to the Kase Filter System

Back in July I shared with you my thoughts on the Kase Filter system. I had made the switch from Lee Filters to Kase Filters back in late 2018, but I wanted to give them a proper test before I told you what I thought about them. If want to see that video and see the images of Boscastle harbour that I captured that beautiful summers evening then check out this blog post here.

Going from Kase K8 to the Kase K9 Filter Holder

As I said in that video, I was very happy with my Kase filter system including the K8 filter holder and slim polariser. I know nothing is perfect but I honestly didn't think there was room for improvement with the K8. That was all true until I picked up a Nikon Z7 with the Nikkor 14-30 mm f/4. With my previous wide angle lens, the Nikkor 16-35 mm f/4, you could happily shoot at 16 mm with the K8 and polariser with no vignetting. However, at 14 mm on the Nikkor 14-30 mm with the K8 and polariser, you could get a little bit of vignetting (the same applies for the Sony GM 16-35 mm.

So when the team at Kase Filters UK told me about the improvements they had made with the K9 and asked if I'd be interested in trying it out I jumped at the chance. I was keen to put this new K9 filter holder and polariser to the test but I needed a suitable location. Where could I shoot super wide angle images that need a polariser? Dawlish Warren beach of course!

Super Wide Seascapes

The removal of vignetting at 14 mm isn't the only improvement to the K9, there are a number of other minor, but very welcome improvements as well. If you want to know what they are, or if you should upgrade to the K9, then check out the video below:

When I got my Nikkor 14-30 mm f/4 lens I didn't think I'd notice that extra 2 mm or use it that often, but as it turns out I really appreciate it. Not only does it give me more creative options in certain scenarios, but the image quality and sharpness, particularly around the edges seems to be much improved over my trusty old 16-35 mm f/4. It's also good to know that I've also got a filter system that can make the most of those super wide angles and help me create images like this:

I hope enjoyed this quick look at the K9 and the images I captured that morning on Dawlish Warren. If you've got any questions about the Kase Filters system, the K9 or the images I captured let me know in the comments below.

A Quick Word on Moving to the Kase System

Since moving to the Kase Filters system a number of regular readers of the blog and viewers of my YouTube channel have asked about how easy it is to move from another filter system to Kase. Well, the good news is that if you are coming from another 100mm based system such as the Lee100 Filter System, most of your existing ND and ND grads should work just fine in the K9 or K8 holder.

The Lee Filters range of Stoppers, which have foam on the inner edge, need to be slotted in with the foam facing outwards (as shown in the image).

Kase circular polarisers (CPLs) are designed specifically for each of their filter holders so you probably won’t be able to use a CPL from another manufacturer. The good news is that the K8 and K9 filter holder kits come with the correct CPL for that holder.

I appreciate that changing filter systems can be costly and the need to gradually transition is an important one so I hope this information is useful for you. I would of course recommend you plan to replace your ND and ND grads with Kase equivalents as Kase filters have some useful benefits (which you can hear about in the video below).
