Mr. Ambiguous Posted March 2, 2017 Share Posted March 2, 2017 Hi everyone! I apologize if this have been covered here before, I searched and googled for it but came up empty handed (feel free to send me a link if you know any) So, I have an upcoming project which are about to shoot this summer. At our disposal we have a Sony A7s II together with the Sigma MC-11 Canon to Sony adapter and also a Speedbooster for those APS-C shots. We've been looking at the Anamorphot 1.33 - 50. At SLR Magic's website they state the following: "40-85mm focal length can be used for Full Frame sensor." Since the Anamorphot adapter will make the focal length wider, is there a way to calculate what for example a 50mm lens will become equivalent to (in terms of focal length) with the 1.33 -50 Anamorphot adapter? Is is as simple as multiplying the focal length of the lens by 0,77? (Figured x0,77 since the adapter squeezes the image by 33%: 100% - 33% = 77%) A 50mm turns into 38,5mm? A 85mm turns into 65,45mm? Also, why 'can't' you use a lens above 85mm? //cheers Quote Link to comment Share on other sites More sharing options...

Awesome, great tool! Watched a lot of your videos on YT, looks like you know your stuff I bet it's hard though to find a sharp taking lens above 85mm with a small enough front element to be used with anamorphic adapters?

Thank you! Make sure to subscribe! And yeah, that sums it up. I bet one of those compact 85/2.8 would do an amazing job, but I haven't had the chance to test one yet! :D Mr. Ambiguous 1 Quote Link to comment Share on other sites More sharing options...

Keep up the good work Yeah I've been looking at a few lenses now and most of the narrower ones have quite a big front element, but I've found a few that might do the job. I'll post another thread where I've gathered a Canon prime setup, I'd love to hear your input on that once I've posted! //cheers Quote Link to comment Share on other sites More sharing options...
