In video recording on Zoom auto focus work or not

Hi,
I am interested to buy S100fs but In some review I read that S 100fs has some problem with focus setting in video capture mode with zoom. Please tell me how much video quality will impact and whether its comparable to other digital camera like Canon S5 or not.

Thanks in Advance

That's because it doesn't zoom durign video recording. You'll need to zoom first, then press record.

I haven't seen the results on a TV screen but I have tested this feature in a Jessops shop. I can confirm that it does refocus while recording video - there is a short delay if you go quickly from full wide to full tele but to me it was acceptable for a stills camera.

Actually, the camera can zoom during video recording (since it uses a mechanically linked zoom ring) but the zoom ring is quite stiff for smooth transitions and you might not get a smooth zooming effect like you would with something like the Canon S5. It would however be easy to get a sudden stataco zoom (wide to tele) which you probably would not be able to do with an electronic zoom (like on the Canon S5).

About the focus, it depends on which auto focus mode you are set in. If it is continuous AF, it will keep focusing and if it's in single touch, you would have to half press the shutter every time you went out of focus, which is also okay.

Hello all,

Zubin is correct, the S100fs does indeed zoom while recording, and with the manual zoom ring, it is very easy to get exactly the zoom position you want. My Fuji is about a month old and the zoom is very smooth, much better overall than my Sigma 18-200 dSLR lens, and it does not show any signs of lens creep (lens zoom mechanism moving as a result of gravity/weight). Yes, I love this camera.
