Now that you’ve heard my thoughts on the Freewell Prism Filters, first let’s look at some samples with the prism filter. These were taken at f/5 and f/7.1 on an 85mm lens, 77mm filter thread.

I had to stop down this far to get much distinction out of the subject, Roumy, otherwise the repeating patterns were too indistinct from one another. Obviously it’s quite difficult to get a portrait out of this lens, at least one so close up. I suspect it would be more ideal for other subject matter.

Some images with the prism filter now. For all of these contrast is pushed a fair amount to bring back proper tones. These are nearly all shot at f/6.3, which I found to be the best compromise for clarity vs effect. Except for one at f/1.8, and I think you can figure out which one that is ;)

Next we’ll look at the split diopter filter, my favourite of the bunch to use. If you’re unfamiliar with the diopter effect, it alters the depth of field for a potion of the frame, so this filter crates vastly out of focus ‘auras’ around our subject Roumy. These are shot between f/3.2 to f/6.3. Going any wider spreads the out of focus areas too far, and any narrower creates too much distinction between the areas.

Now let’s take the centerfield split diopter out for a cold and rainy stroll through the Christmas lights.

And there you have it. If you want to pick up any of these filters, feel free to use one of my affiliate links to help support this channel, and feed my fat cats:
