SLR Magic Rangefinder Cine Adapter (Calibrated in Feet)

Key Features

Simplifies Anamorphic Focusing
Manual Focus Control
Minimizes Breathing on Still Lenses
For Lenses with 77mm Front Threads

Made to greatly simplify the process of focusing with anamorphic adapters, this SLR Magic Rangefinder Cine Adapter provides a calibrated focus scale, marked in feet, industry standard focus direction, and a cine-style focus gear for your lens set up. When using most anamorphic adapters that mount to the front of your lens, focusing requires matching the distance on the anamorphic adapter and the lens itself; this can cause problems when trying to pull focus. However, when using the Cine Rangefinder, you set both your anamorphic adapter and lens to infinity and pull focus on the rangefinder.

SLR Magic SLR-77RFWM Overview

You can use the Rangefinder Cine Adapter to provide accurate focus markings, and using the adapter minimizes the appearance of lens breathing. It mounts to lenses with 77mm front filter threads, and you can use optional step-down rings for lenses with smaller front threads. The adapter integrates a cine-style focus gear, allowing it to easily interface with a variety of optional focus accessories. It allows you to focus your lens or lens/anamorphic adapter combination from 3.5' to infinity.

Works with SLR Magic Anamorphot adapters (1.33x50 and 2x50) to provide single gear ring focusing.

You can use the Cine Rangefinder on lenses without an anamorphic adapter as well. This is useful when working with lenses such as Nikons, which focus in the opposite direction from cine-style lenses, or when using lenses that have neither focus gear nor reliable distance markings.

Using the adapter allows you to minimize the effects of breathing that your lens or lens / adapter combination would ordinarily suffer from.

Once your taking lens is properly set to infinity, the focus distances on the adapter (marked in feet) are accurate and repeatable.

The adapter provides your lens with a focus range of 3.5' to infinity. Even if your lens or lens and anamorphic adapter combination by themselves do not focus as close as 3.5', using the adapter brings the minimum focus distance to 3.5'

The front 82mm filter threads of the adapter rotate as you pull focus on it. This may cause unwanted optical effects when using filters such as star or polarizers.

Great Cine Adapter by SLR M

I truly value the quality and build of this Cine Adapter by SLR Magic. I do recommend this for anyone who is interested in converting their lens into a Cine Lens.

Does what it's suppose to, but not without issues.

Unlike many others, I had few issues getting sharp images from the Rangefinder. I just followed the suggested guidelines from SLR Magic and made sure my taking lens and anamorphic were actually at infinity (Please don't just turn the lens to the infinity marking and assume that's infinity, always test on a far away object first, especially with old lenses.) My issues were the blue flares and spots that sometimes appear at the worst times. It you are flying a small rig and don't have a matte box (You will definitely need one) light at the wrong angle just gives these horrible blue spots that clash the image really badly. Also, on some taking lenses with modern coatings, when you WANT it to flare, it flares weird occasionally... like a weird blue blob appears on pans. This is not a good run-and-gun focusing solution, as many of tried to state it is. If you are going super light without a follow-focus it's huge and difficult to focus quickly. The Rectilux without focus gears is better suited for that. If you are shooting in a controlled environment with a solid rig and this is all you have access to, the Rangefinder works fine. There are just too many of the wrong optical surprises for run-and-gun use. For the price, especially used, it's definitely not bad. Just don't expect perfection. I sold mine after shooting 10 hours of test video in various environments while on other jobs. It just doesn't work well for what I want.

question

Will this work on a Isco 1.9x anamorphic lens?

Asked by: David

It would depend on the size of the front of the Isco 1.9x lens. Even if we knew the exact lens, this information seems to be unavailable since the lenses appear to be out of production since 2001. If it is 77mm or less (by using step down rings) it probably will work. However, without the two pieces in hand, we are unable to say for sure.

question

Does the threaded front rotate as focus is rotated?

Asked by: Thomas

so basically pickup the Genustech fader ND 82mm or the SLR Magic Variable ND both has little to no color casts and are rotatble (good for fixing the 'underlying polarizing' effect due to the variable ND's

question

do the diopters that come with the 1.33x set work as well to help the rangefinder focus closer if you attach the diopter first to the 1.33 then the rangefinder to the diopter?

Asked by: Anonymous

We are of the opinion that the results will will be the same whether or not it is possible to do what you are surmising.

question

Will this work on a Panasonic LA7200 1.33x anamorphic lens? It has 77mm threads.

Asked by: Mario

Well, in the chain of lenses , we have the taking lens (mounted to camera), the anamorphic lens (mounted to taking lens) and finally the SLR Rangefinder mounted to the anamorphic lens. This means that it would be necessary to find some way to mount the Rangefinder on the front of the LA7200; probably not easy and probably subject to vignetting. While there are other reasons besides the single focus capability to use the Rangefinder, be aware that one of the LA7200's great advantages is that is a focus through anamorphic; that is, the action of the taking lens focusing does the job. Hope this helps.

question

What the difference with this model? https://<a href= http://www.bhphotovideo.com/c/product/1211003-REG/slr_magic_slr_72rfnn_rangefinder_cine_adapter_with.html target= _blank >www.bhphotovideo.com/c/product/1211003-REG/slr_magic_slr_72rfnn_rangefinder_cine_adapter_with.html</a>Looks similar, but that model twice cheaper. Cause of 72mm this device for 77mm lenses?

Asked by: Dmitriy

If I remember correctly, the glass and front are exactly the same. The only difference is the mounting on the back and the imperial focus marks on this one.
