Thank you for the video. You are the first one who did a more extensive review. There was a lot of rumors that this Speedbooster has a lot of bugs. Seems to me yours works fine. Thanks again.
Somehow this is the only video on RUclips for Meike speedbooster review for Rf series. Is it possible to make some more tests for photo and video. I have r10 and ef-s lenses but planing to buy 24-105 f4 or 24-70 f2.8 and if there is no problem with video (autofocus and is ), 24-105 will be awesome with speedbooster. Thank you
@@jadersuriano the trick is to use manual lenses with no IS. I purchased a viltrox ef-Eos r pro mount adaptor and a manual lens and the Ibis works just fine - with minor wobble - but the Ibis wasn't behaving when I tested with the meike speed booster for video 😢
@@andydlamini It's not a big deal for me buy an adapter and don't use with a autofocus lens. I prefer the Meike EF RF adapter with nd filter, autofocus works great and no problem with ibis.
it shouldn't be reporting back to the camera that you're using a 17-49mm F2 lens because you are not. The 24mm focal length is multiplied by 1.6x because the camera is a crop sensor one, so now you have a 38mm lens, and then you use the speed booster and the focal length is multiplied by 0.71x so it's a 24mm again. It is, though, what a 17mm lens used on a crop camera would look like but it doesn't make sense to use that analogy instead of just saying it's a 24mm. Same goes for aperture as well. If you'd use this speedbooster on a full frame camera then yes, you'd have a 17-49mm F2 lens, ignoring the fact that your photo would be a circle
It makes sense to use that kind of analogy because that's what the optical system in front of the camera actually becomes. different sensor size is just pre-cropping the sensor, changing the optical system actually affects focal length and light density projected on the sensor (as in f stop).

Dude, whythere isn't a resolution test in this review, i want to know about picture quality

Thank you for making this video. I needed to know what the custom thumb ring was for 🙂
My ef-s 10-18mm doesn't seem to mount on the speed booster though? Have you tried to mount an ef-s lens?
@@andydlamini I do not have EF-S lenses. Did you line it up to the white dot and not the red?
Hi, I did but it doesn't seem to go all the way in, and I'm assuming it's because of the protruding rubber ring on the 10-18mm lens...
@@andydlamini L lenses have a rubber gasket and I didn't have an issue.
@@1KINDPhotography Yes L lenses have no issues because they are full frame 'EF' lenses but thanks for your video 🙏

Hello. I want to see a test with AF in both photo and video mode. from the test presented above there is nothing relevant. thank you
Speed booster still working well?
Did you noticed any optical issue or is it good in that point?
@@joaovtaveira I have not noticed any optical issues.
@@1KINDPhotography that is great news, thanks.
Hi! Did you experienced any issue with the stabilization? The Viltrox speedbooster has a problem with estabilization, this one hasn't?
Did not notice any issues with stabilization during testing.
Tested it with my Canon EOS R7 - which has Ibis - and it wasn't stable...
@@andydlamini I have a R7 too and this is what I was thinking. Some users said about this problem with ibis and this the reason I will not buy anymore

Anyone try this on a Komodo？
No image test with and without speed booster renders this video useless.
Will it work on the r7
Yes
@@1KINDPhotographyI’m having a hard time finding one

The reason it does this is because even though there is a crop factor of 1.6 the camera will still report it as 24mm, so it makes it messy.
