Chapter 3E: Anamorphic Lenses
OK, this is really getting interesting now. So, for those of you who don't know what is an anamorphic lens....wait, one sec. First we have to talk about aspect ratio!
The aspect ratio of an image describes the proportional relationship between its width and its height.
I just couldn't say it better than that. Please don't confuse this with image resolution as many people do. This has nothing to do with the actual resolution of a camera. In the next picture you will see the most common aspect ratios used today in the world of filmmaking:
Now that we got that out of the way:
Is it better to shot in anamorphic than widescreen? Well, it depends. It is a tool.
For many years anamorphic format has been used by some of the greatest directors to portrait a reality in a more immersive way. Movies like The Good, The Bad and The Ugly, needed to be shot in anamorphic to immerse the audience in this vast space in the desert:
While films like The Grand Budapest Hotel, are perfect in their less wider aspect ratio:
Also, anamorphic lenses tend to have very attractive flares and an oval-shaped bokeh. So, it depends on the project but I'm getting off-topic.
There are two ways to get an anamorphic optical image: with an anamorphic lens or with an anamorphic adapter in front of our normal lens. The anamorphic lenses are incredibly expensive, even the old ones. A good anamorphic lens can easily cost thousand of dollars. So I'll just leave that option out of the equation.
The second option is with an anamorphic adapter. This is a much, much cheaper way to obtain anamorphic optical image BUT it has its cons:
- As you will have the anamorphic in front of your habitual lens, you will have to focus with both lenses. Which is not practical at all and will most likely make your shot incredibly difficult.
- Again, because you are using 2 lenses, a loss of resolution and a softer image must be expected.
- Most of them are huge and will make your rig a lot bigger, bulkier and heavier. Not good news for your steadycam operator.
Now, if you are adventurous enough and despite those cons you still want to get an anamorphic adapter, here is something very important you have to consider. Anamorphic adapters come for different aspect ratios. A adapter that says 2x will create an anamorphic image from a 4:3 aspect ratio. A 1.3x adapter will create an anamorphic image from a 16:9 aspect ratio. Basicly, if you put a 2x anamorphic adapter on your 16:9 camera, it will create an ultra widescreen image, and not the traditional 2.39:1. You need to find the adapter right for your camera's aspect ratio.
16:9 = 1.3x anamorphic adapter
4:3 = 2x anamorphic adapter
Now, enough of theory. As for lens suggestions, because most of these lenses are used and old rarities, I would suggest you to search on ebay and save a search. Then ebay will ask you if you want to be notified when a new item with that description is at sale. That way you will be informed if there is a good deal. Like these:
Meopta Anagon 2X 82.5mm Anamorphic Lens - Price: US$ 201.00
Century Optics 1.33x Anamorphic Lens - Price: US$ 675.00
You might need one of these clamps to adjust your anamorphic adapters on your normal lens:
Finally, for some of you who wonder:
Wait, what if I just crop the image?
It's a way to do it. How ever you will only get the wider image. You will lose the coolest things about anamorphic, like oval bokeh and those nice flares.
This is obviously a personal choice. I personally really like the anamorphic look, but I rather wait till I can spend US$ 3,000-5,000 in a real anamorphic lens, and not an adapter. Adapters seem too difficult and impractical for real shooting.
Anyways, I hope this gave some of you an idea of how anamorphic lenses work. Please buzz and subscribe if you found this useful, and leave a comments if you have any questions or just want to say hello!
