My favorite?

I’ve shot recently with the Arri Master Anamorphics and the Red Monstro. You can watch more about it in my Monstro review. I actually used the higher focal lengths to get by 7K 6:5. When I went 50mm or lower, there was vignetting. However, I was also shooting 5K here, so I could crop for a 4K DCI 2.39:1 finish. The point is, the Master Anamorphics are limited when it comes to resolution, but it’s still a great choice on the LF and Mini LF if you’re okay with the crop. On the other hand, Master Anamorphics are fine for the LF and Mini LF as far as Netflix is concerned:

When shooting with 35 format 2x anamorphic lenses for a 2.39:1 aspect ratio result, Netflix accepts the use of a
3148 x 2636 area on the ALEXA LF and ALEXA Mini LF sensor.

However, it’s hard to recommend them for all kinds of work. Recently I had a chance to play with the Cooke anamorphics and the P+S Technik anamorphics, and I must say I’m most impressed by the Cooke Anamorphic/i Full Frame Plus Standard, for these reasons:

  1. They give me an actual 4K resolution and I can still shoot open gate.
  2. The Cooke look.
  3. Better front focus than the others on this list.

What do you think?

Hi . What I noticed was scorpions doesn’t have ovel bokeh and anamorphic flare . If they would give anamophic perpective as you know for instanse . When you shoot 35mm in full frame but magicly It would give 24mm field of view with 35mm perspective. I would be happy but if as it’s looks . just have physical hood front of first glass which crops top and bottom . It’s ridiculous . But about cookes .did you use 32mm as well ? Did it gave you 16mm field of view of FF with 35mmFF perspective ?

Not everyone prefers oval bokeh or anamorphic flare. But it’s an economical option for a lot of shooters who can’t afford the top range options. I don’t understand your second question.
