I am selling the close up I used for this tutorial on eBay. It’s in perfect shape, no scratches or blemishes and perfect shape. I would love to keep it, but I already have plenty diopters, so it will be happier on somebody else’s hands.

Hey there, Tito Ferradans here! Last week we talked about splitting diopters, and it was extreme, so here’s the cheapest – and easiest – way of getting a +0.5 diopter. +0.5 diopters are particularly coveted for their 1-2m focus range, which is the hardest focus range for most anamorphic adapters, so they go for higher prices and aren’t very common. If you wanna know more about diopters, I recommend checking this article on the Anamorphic on a Budget guide, where you’ll find all the math and effects of using diopters.

For this tutorial we’re gonna need an empty 72mm ring, with the retaining ring intact – you can get the spares from last week, like me – or just order a cheap 72mm UV filter. A lens wrench, an exacto knife and, the secret piece, a Tamron 28-200mm Close Up filter. They go on eBay for under $30 and are fairly common, the only problem is that they come in a weird mount without filter threads.

You might’ve guessed this step: Remove the diopter from its retaining ring. These flaps keep it in place, so rip them off using the exacto knife. Take your time and be careful not to score the glass. Now put it on the 72mm ring and screw back the retaining ring. Lastly, celebrate and go out to shoot the medium-to-close-up shots you used to struggle with.

This was more of an insider trick rather than a real tutorial, trying to shine some light into the tricks I learned along the way that don’t necessarily involve buying expensive lenses or tricky DIY stuff. It’s something I believe will benefit most anamorphic users out there. If you found this useful, subscribe now and keep an eye for the following videos, for they should be helpful too.

JULY 13th, 2016 – UPDATE: After posting this tutorial, a friend reached out about a unusual Tamron diopter that, according to him, is only sold in Japan. WHOISJSD confirmed that the Tamron A9F Close Up Filter is indeed 72mm threaded and +0.5 in strength. Here are his tests. The one I use in the video is the A9FB (B for Bayonet). The only problem is that it’s hard (impossible?) to find the A9F on eBay. If you wanna give it a shot, contact WHOISJSD through Instagram or Twitter and see if he can grab one for you! He warns they would go for about $50 though, which isn’t so cheap compared to the mod option. “That said, the quality is excellent. No ghosting, no chromatic aberration. I’m a fan. We did a lot of shots with it on my friend’s Sony and my 1.33x [anamorphic]“, WHOISJSD says. On the bright side, you just need to take it out of the box and shoot.

    […] believe it’s a useful technique for medium close ups. If you can’t afford a +0.5 diopter (seriously?!), I’d say it’s a reasonable solution. The edges become more messed up, but they’re […]
