In the end, we never stop talking about these suckers across multiple threads, so I'm gonna try to compile as much information as I can into this one.   As in most cases, diopters are cheaper than a

Hi all, Inspired by Tito and Bold and their anamorphic Lens-cyclopedia, I decided to try and make a list of low power diopters useful for anamorphic video. Using the info in this thread and searching

Well done, man! +0.25 is hard to get! I have this minolta, it's almost the same as the Tokina +0.4, except it's +0.33 http://www.ebay.com/itm/111827493087

Tito, asking, you're a guru! Is it possible to put the single focus element not in front of anamorphic lens BUT between the taking lens and anamorphic. It would be easier for focus pulling and matte box usage.

Thank you!

Heya! No, that won't work because optics don't work that way. :)

Hello everybody, I'm selling a couple of diopters. They are all in good shape (Tokina and Tamron nos). 

- 72mm Kaiser +1

- 72mm Pallas (made in Japan) +1

- 67mm B+W 0.5

-55mm Kenko achromat 0.0

-72mm Tamron (threaded!) 0.5

-72mm Tokina 0.5

I don't have a clue about pricing. I consider Tito's list from page one outdated?! So just drop me a line when you are interested.

I found a set of 46mm +0.25 and +0.5 dpts close up lens on ebay if anyone needs that: ebay.de

I ordered the same in Series 8 size (https://www.apotelyt.com/photo-accessory/series-filters) I think their outer diameter is about 63mm but they are not threaded, it'll probably be to small for my lens so I might sell them in the next few days, PM me if you're interested. 

I sourced an optician that can provide me a +0.25 diopter 65mm glass element but I have no idea how I could attach that to my lens, any one has experience with custom glass element holder / clamp ?

Hi everyone, i'm having a hard time distinguishing between the many types of closeup lens attachements. I have an aivascope anamorphic adaptor with an 82mm front thread. It focuses to about 1m away, but I would love to have an adaptor to do extreme closeup macro shots (within 1') of the lens.

I've seen closeup lens filters for as little as $3 all the way to $200 for the Hoya set, all claiming to do the same thing. Can anyone explain why there is such a variance in price? Is there nothing available for around $50 that will do the trick well enough?

Here's some info on the price/quality variance

A very short extension tube turns ONLY your spherical lens into a macro one.
The anamorphic adapter is an entirely independent optical block and therefore is not affected by it.

If you put a diopter in front of the entire setup (assuming it's properly focused, meaning: you can get a sharp image from it), then it acts globally.

      eBay Listing: http://www.ebay.com/itm/112426475899?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
      Superb close focus lens filter / diopter. Size 72mm filter thread. Increases minimum focus distance in front of lens. Same result as a macro lens or macro extension tube. Purchased 2, selling 2. Both in excellent condition. No scratches or dings. Threads perfectly in tact.
      These are the non-bayonet A9FB version, that come in 72mm filter size. 
      I sought this filter out specifically for shooting video on modified anamorphic lens adapters. Vintage anamorphic lenses typically are handicapped by close focus distances of over 1 meter or more. Stacking 1 or more close-up diopters on the end of your anamorphic can decrease this minimum focus distance. Stacking multiple diopters on top of one another will minimize this close-up focus distance even further, without noticeable distortion.
      +1 lens filter equals roughly .8 meter minimum focus distance.
      +2 lens filter equals roughly .5 meter minimum focus distance.
      These are also wide & slim enough o they don't produce a dark vignette in the edge of the frame. I used step-up/step-down rings to mount to my lens.
      *Be aware you won't be able to rack focus very far, or focus to infinity with this on. It is not a one size fits all solution.
      I'm told these adapters replicate what a Tokina +.4 achromat diopter can do at much less the price.
      Payment via PayPal only. Questions welcome.

      Hi Guys,
                   I'm looking to purchase a set of Voigtlander 95mm Focar A or B diopters to use with an Iscorama 54. Hoping someone has a set for sale as Ebay hasn't listed any lately. I just joined the forum after reading the posts for quite some time. Thanks in advance.

      Hey everyone, I'm looking to buy a Helios 44m-7 lens.  I don't trust ebay with this lens as it looks like most are switched plate fakes, unless you know of a reputable seller with one.  Also looking to pick up a Tokina +0.4 Diopter, if anyone would like to part with theirs.  Thanks!

      Can some explain to me why +0.4 and +0.5 diopters are more desirable than +1 diopters? Are +1 diopters terrible? I would assume using +1 would grant the user the the option of being able to shoot at the distance a +0.5 allows and closer since its +1. Maybe someone can enlighten me on the pros and cons of each diopter strength.
