EphraimP Posted July 27, 2020 Share Posted July 27, 2020 A Metabones EF to X- mount Speedbooster hit my doorstep Friday and I've started to play with it a bit. I know it was mentioned in a conversation about EF adapters on a recent Fuji thread but I can't remember which one. I'll give my impressions on it once I'm more familiar with it, if people want that. First impression it that is produces a nice image quality with my 17-40L and 180 L macro. I took some shots with my 70-200 L 2.8 (old non-is version) but I haven't looked at them yet. The autofocus works with both the wide and telephoto zooms, though I'm not sure yet how it compares to native lenses. I did a side-by-side setup with the wide Canon zoom on my T4 and my XF 17-55 2.8-4 but I haven't had an opportunity to look at them side by side yet. On a separate note, I'm running a test on the T4 right now to see how long it can record in DCI 24p with HDMI out to a Ninja, not recording internally. I know internal recording has limits and possible heating issues, so I'm testing HDMI out recording first. Later I'm going to test how many times I can restart internal recording in DCI or 4K before heating is an issue. I'm recording in my home office, which 78 degrees Fahrenheit, 25.5 C for those of you who live in a place with a rational measurement system. Tomorrow I'll be using the T4 on a doc project outside with temps around 92/33 degrees, so we'll see how it does in real-world conditions. Btw, is it possible to turn IBIS completely off on the T4? When I turn off the OIS switch on my 17-55, the IBIS option is grayed out in the menu, but the boot mode is still available? And what if I'm using an non-stabilized third party lens like my L-glass or Meike prime? ade towell 1 Quote Link to comment Share on other sites More sharing options...
