nicknabors Posted May 31, 2017 Share Posted May 31, 2017 I'm sporting a T3i and I have a NAP2-3m. That adapter only covers ~80mm FF equivalent without vignetting from a 16:9 ratio. Does anyone know of shorter focal length 2x adapters that can cover 50mm FF equivalent without vignetting, or possibly shorter? I want to be able to shoot wider for some shots.

Justin Bacle Posted May 31, 2017 Share Posted May 31, 2017 May I ask you would want to use the full 16:9 aspect ratio ? This gives a final ratio of 3.56:1 which is basically unusable IMO. I record in 4:3 or 1.2:1 myself as I am aiming at a 2.40:1 final aspect ratio. In that case you can use wider lenses Quote Link to comment Share on other sites More sharing options...

In that case you can use wider lenses If I could go 4:3 I would but I'm not worried about the final aspect ratio. If I had a gh4 or gh5 I would love to use that for anamorphic but I'm limited to the T3i. I would just like to know about any wider adapters. Some say 35mm but they aren't 35mm. So that's the dilemma. Also if I crop to 4:3 in post, I lose detail so that's why I'm shooting in 16:9 Quote Link to comment Share on other sites More sharing options...
Justin Bacle Posted June 2, 2017 Share Posted June 2, 2017 80mm in full frame when shooting 16:9 sounds quite wide already You can use @Tito Ferradans's calculator here http://www.tferradans.com/blog/?p=13386 to check your possibilities Tito Ferradans 1 Quote Link to comment Share on other sites More sharing options...
