Thanks for that Joe
I have at last made my mind up to get a VG900 looked at loads of lenses,apart from SONY 18-200 LENS which does have auto focus all the expensive lenses CANON 24-70 etc none of the auto focuses work, just why is that it seems a bit daft to me' when you go on you tube and watch all the lens reviews they talk about how quick they can focus why the heck does it not work on a video camera .I watched a review on the TAMRON Think it was 80-300 imagestabalization (vc) etc focused on a small object on a pole it was pin sharp so please someone explain why auto focus does not work on a vg 900 with this sort of lens on the front .Meny Thanks Wilf.

Hi Wilf, sorry about the late reply but I just seen this post. The VG900 only has AF with E mount lenses as far as I know. I have the new Sony 16-50mm OSS power zoom lens that I use on my VG900 in APS-C mode. The new 18-200mm OSS power zoom also works the same on the VG900 with control of the zoom on the VG900's zoom rocker switch and you can set the zoom speed in menu. I also have a 28-300mm full frame Tamron zoom that I tried on my VG900 using a PK-NEX adapter in manual mode. I don't think there is any full frame camera that could AF in video mode with full frame lenses except the A99 but I think it only works @F3.5 and faster apertures.

Here are photos of my VG900 with Sony 16-50mm OSS power zoom in off and on positions .
