Anamorphic Lens Calculator: What Lenses Will Work?

Posted by | Cinematography · Tutorials | 6 Comments on Anamorphic Lens Calculator: What Lenses Will Work?

Updated Oct 17th 2017.

Our most common question from those interested shooting with anamorphic lenses on their DSLR: will my camera and lenses work?

The DSLR anamorphic lens calculator below makes answering these concerns much easier. Just input your lens, you camera specifications, and hit calculate to see what you will need to be able to shoot anamorphic on your DSLR.

Why do longer lenses work better with amamorphic?

Remember that when using 2x anamorphic lenses, you are doubling field of view. Using longer lenses is perfectly acceptable from a cinematography standpoint as they will render much wider in anamorphic and give more freedom to compose a frame while emphasizing anamorphic bokeh. A 100mm anamorphic setup will result in the same field of view as a 50mm aspherical (non-anamorphic).

If you’re shooting with a full frame camera and want to use wider lenses, check your options to enable crop mode on the Sony A7s or shoot in x3 or x10 mode with Canon Magic Lantern.

hello,

i have a couple of questions with regards to one of your isco lenses.

Specifically this one:
http://www.ebay.com/itm/Isco-Micro-2X-Anamorphic-Lens-for-GH4-DSLR-READY-TO-SHOOT-w-clamp-amp-58mm-filter-/181748133837?

i am looking at ANAMORPHIC set up for my gh4 and was wondering about if this workflow would work after reading your tutorials.

YOU SAID THAT YOU RECOMMEND HELIOS 58MM LENSES FOR PRIME. I FOUND A Helios 58mm f2 Lens for M42 Mount ON EBAY AND WAS WONDERING IF THIS WOULD WORK ON THE GH4 WITH THIS ADAPTER: (https://www.amazon.co.uk/Fotodiox-Lens-Mount-Adapter-Mirrorless/dp/B002RJKVY2).

iT SEEMS LIKE IT WOULD FIT BUT WOULD RATHER CHECK WITH AN EXPERT BEFORE PURCHASING EVERYTHING.

Thanks,
Connah!

Hi Connah, that lens adapter will work perfectly for mounting the Helios. Just make sure that when you buy the Helios that you specifically order the M42 mount, as there were variations in M39 and other mounts.

Hello,

I have a c100 with a 24-105 L series kit lense. I want to use an anamorphic lens but i am not sure which type (of the isco) to get. I do not shoot macro so i would want a lense that does not restrict me to that.

Thanks!

Hello Abe, thanks for your inquiry!

For anamorphic lenses, we would typically recommend to purchase a set of cheap vintage primes over using a zoom lens. Specifically, the Helios 44-2 (58mm), the Jupiter 9 (85mm), and vintage Japanese 35mm lenses (Soligor, Nikkor) can be found on eBay for less than $100, work with Canon cameras via AF-EOS and m42-EOS adapters, and pair very well with the Isco Micro anamorphic lens.

What is the sensor crop factor for 16mm film?

Anamorphic Lenses says:

August 28, 2017 at 6:55 am

16mm film is approximately Super 16mm, so the Black Magic Pocket Cinema Camera option will work, or 2.4x. Make sure to set the aspect ratio to 1.33:1.
