Sigma +0.5 72mm - this one is interesting since it's a low power, but has this dreadful bayonet ring. I though about buying it, since it's very cheap, and trying to fit into a 72mm UV filter, without the glass. If someone is up to the task, go ahead!

I have two of those, bought one on marktplaats.nl for 10 euros :) Ordered 2 chinese UV filters for a few euro's, just going to break the glass and superglue the thread to the Tamron (it's not Sigma ;)) filters. This should work fine, I already put it on another 72mm filter (that I don't want to break) and it fits exactly.

 

 

Just bought a super cheap achromat (€30 incl. shipping). Minolta No. 0 (+0.94). It's only 55mm, but it might fit on my Iscomorphot 8/2x.

Just got this one in. Tried it holding in front of my Iscomorphot 8/2x and it brings the focus down to something like 1,2 meters, have to measure it exactly. No vignetting with 50mm taking lens on Panasonic G6. Looking good!

 

Waiting for some step up/down rings to make a filter solution for the Iscomorphot.

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

I've been waiting to hear this since forever! Relatively cheap 72mm diopters, at last! :)

Hello, I think part of this question is related to diopters so I think I'd post. Hope it's oaky. I've been searching for a solution but haven't found any discussion. Is it possible to mount 77mm Hoya diopters on 15mm rods in front of a lens? 

 

I've got a huge Rectimascop 48/2 X II. This version has a rare 3 meter minimum focus distance rather than 6 meter from what I've seen online. The front element is too large to use a filter clamp. So I'm trying to see if there is a way to mount my Hoya diopters or filters separately on 15mm rods. Any suggestions?

Woah... I don't think that would even be safe... I mean, to get it fixed/stuck to something, it would have to resemble a clamp, so, I'd risk saying you're probably better improvising something to stick to the lens.

 

Tell me more about the Pentax's, I have never seen the T ones ,,,

I've never seen them either. Sound like good options, though. Low power and big sizes!

Thanks for the reply. That's what I'm trying to figure out, to secure it. I was wondering if there is any product that holds filters with adjustable height, something like a mattebox (with 15mm rod clamps) but only the filter part (I can imagine an O ring shape) that comes with different diameters and threads. 

 

Maybe I'm thinking too far for this. Just trying to find a solution.

Stanley; you could buy a cheap 77mm UV filter (break the glass) or a 82mm-77mm step down ring, and solder this ring with some kind of 'holder' to a rod clamp.

 

Or buy something like this:

telephoto-long-lens-support-mount-rod-cl

 

Superglue the Step down / emtpy UV filter to the top of the Lens Support. The height is adjustable :)

I thought about this, but it might be too expensive, no? :P

Haha no worries,! Love this topic and the anamorphic eBay topic btw, keep up the good work!

 

 

Minolta +??, 67mm, for Autopak Super 8 camera.

http://www.ebay.com/itm/330915280246

 

I'm almost sure this is a low power since it wouldn't be of much use to Super 8 shooters if it restricted focus too much. Couldn't find any information on google about it. Ends in 4h.

 

I got this one in today. It is definitely more than +1. With my Iscomorphot 8/2x it lets me focus from around half a meter.

Oh well, I can do anamorphic close ups now :) Not bad!

      FOR SALE: Tamron Close-Up adapter / Diopter lens for 28-200 A9F 72mm
      By DIGICHombre
      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.

      WTB: Helios 44m & Tokina +0.4 Diopter
      By brianmcall
      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!

      Why are +0.4, +0.5 diopters more desired than +1 diopters?
      By harharj
      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.
