Focuser 8 – Single Focus Solution

September 23, 2018

The Focuser 8 is the single focus supermatch for last week’s Aivascope. A tiny single focus solution for baby anamorphics at a very competitive price point.

Tito Ferradans here for a quick episode on yet another single focus solution. The Focuser 8 – as the name says – is aimed at 8mm scopes, so it is the smallest single focus out there. This one is made by Valdas Misevicius, the same guy for the Aivascope I talked about last week.

So, what’s the deal with the Focuser 8? It goes in front of your double focus or locked focus scope (such as the Baby Hypergonar or the Aivascope) and it turns your system single focus. This one has 52mm rear threads and 67mm front threads for attaching VariNDs, Polarizer or even diopters for stronger closeups. It weighs 140g, so it adds next to nothing to your rig.

Focus throw is about 90 degrees and it ranges from 45cm at minimum focus to infinity. There are no focus distance marks, and some versions have focus gears, but others don’t – like the one I’m using here. It doesn’t extend much when close focused either, which is great, roughly one centimeter. Focus is reversed though, which always bothers me tremendously, and the build feels a bit flimsy if you’re constantly racking all the way through.

When it came out it costed $245, sold by VM Optics on eBay, and these days you can find them used every once in a while, or when Valdas makes a new batch. The price hasn’t changed much.

For the sake of image quality comparison, I have it combined with the Aivascope, so we can compare it with last week’s video and, since the Aivascope is not the sharpest lens around, I paired the Focuser 8 with a Bolex Moller 16/32/1.5x and compared it to the same Bolex paired to a Rectilux HardcoreDNA. At 40mm you can kind of say they look similar, but as we move on to longer and faster lenses, the Focuser has a hard time keeping up with the HCDNA. The corners are also severely compromised not only by blur but also vignetting is introduced much early.

My pairing with the Bolex is unfair due to the Bolex’s large glass. The Focuser 8 transformed the way I experienced the Aivascope, allowing me to go much more freestyle without introducing a ton of vignetting. As you can see, this is the Aivascope at 28mm, then with the Focuser 8, still at 28mm, and as soon as we step to 35mm, vignetting is gone, so the slim profile helps by not limiting your choices of taking lenses. And this is how it behaves with the Bolex, without the Focuser 8, the Bolex clears 35mm, but with the Focuser, we’re doomed in vignette-land.

This covers all the aspects about this single focus solution. From your perspective, is the Focuser 8 useful for baby anamorphics, or would you stick to a bigger glass option even if that sacrifices the shape and weight of the whole rig?
