I got a Viltrox speedbooster, and the edge of the frame is a disaster on both my M50 and M3. Anything not in the center square of a 3x3 box is a blurry mess. Trying to AF outside of that center box results in AF misses. I bought a new 85mm 1.4 to use with it and almost sent the lens back until I tried the lens without the booster on a 5D and it was so sharp. When people said that you'd experience some softness with the speedbooster, I think they undersold how detrimental the image quality hit is.
It maybe ok for 1080p video, but I can't imagine that anyone could use this for anything except dead center compositions.
The one i tested worked very well with the 100mm macro IS. It is good at f/2.0 and very good at f/2.8. I can use it perfectly for rule of thirds compositions.
AF is slightly off sometimes, reason for me to return it. I re-ordered it a view days ago, since the price dropped, and my needs changed (want to do video with the 24mm f/2.8 IS USM).
I am surprised to hear it works so bad with the EF 85mm f/1.4 IS USM. If you have invested in this lens, it might be a good idea to get the RP for it.
Video with the 24mm 2.8?
The sigma 16mm 1.4 is a better buy, probably sharper and faster native AF.
A sigma lens has native AF, while a Canon lens has not? Granted, the AF of the Canon lens is influenced by the speedbooster, but that doesn't make a third party lens have native AF.
No need for clunky adapter.
The overall "clunkyness" won't be much worse.
This lens is very popular among youtubers
I am not a youtuber
No IS though
Exactly. And in my case i already own the 24mm IS, while the adapter is only 125 euro. I plan only doing 1080p, which is only 4Mp, so IQ is the least of my worries. Gathering more light isn't that important, i only want a wider focal length with IS, and - in my case - 125 euro is hard to beat.
