Tamron A9F Close Up Adaptor Lens for 28-200mm

• Diopter by Tamron

For 28-200mm F3.8-5.6, most often bayonet (A9FB): remove glass and place in threaded 72mm filter ring. Also a threaded version (A9F)

+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. So here's the cheapest - and easiest - way of getting a +0.5 diopter!

For this tutorial we're gonna need an empty 72mm ring, with the retaining ring intact. A lens wrench, an exacto knife and, the secret piece, and the Tamron 28-200mm Close Up filter (A9FB). They are fairly common on eBay and 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. Rip out the plastic flaps that bind the glass to the plastic frame 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 capture the medium-to-close-up shots you used to struggle with.
