Hi,

I've been wondering how shallow of a depth of field can be achieved with this camera? I understand it has a 1/3 " image sensor, even smaller than last year's Canon HFS21. I want to make short films and web content, so having a shallow DoF is important for me (I don't like using DSLR's for video).

I know the DoF isn't fully dependent on sensor size, rather aperture and focal length, but compared to the canon hfs21. which has a 1/2.6 image sensor, what kind of depth of field would the xa10 have?

That is a DoF test with the HFS21. It seems to get pretty good DoF, and if the XA10 can match it, I'm happy. Do you guys think I can the get same DoF as the video with XA10?

Thanks

I share your sentiment about video with DSLRs. Luckily, the XA10 should definitely be able to match the shallow DoF of the HF S21 -- we haven't seen but a few seconds of footage from the XA10 so far, but those glimpses show video that at least meets that level of DoF. The XA10 should be an upgrade from last year's HF S21 (hey, it sure costs twice as much), so I can't imagine Canon giving it less shallow DoF ability. Unfortunately, with the lack of actual video or an in-depth review of the XA10 (yet) I can't say this with 100% certainty.

Also, Canon has also mentioned that the XA10 is shipping with an 8-bladed iris, which is supposed to produce smoother, more "professional-looking" backgrounds than camcorders with the usual 6-blade iris. More footage will need to be seen before we get a better feel for what that actually looks like.

I intend to use the XA10 for short films as well, so I'm very interested in the DoF capabilities. Anyone else have any thoughts on this?

Guys, I have a general question on the Depth of Field.
Can the Depth of Field accieved in auto mode, or it is something that can be achived just in manual focus ?
Lets say I want to get a video of just the subject and wash out or unfocus the backgrownd, can it be done in auto mode ?

thnak you

Thanks for the reply again!  Grin

Yeah, with the money we're spending we better be able to get that DoF hehe. I suppose all we an do is wait until March.

@ third poster: I think Auto mode sets the aperture at one level and doesn't change it so you might not be able to change the DoF. Its probably best to do it in manual mode. I can't answer this for sure but I'm a manual controls type of guy.

@marcolisi Yes, like with the Vixia HV series there is the "aperture priority" and "shutter priority" auto modes, but like that1guyy said you can always just use full manual controls and get the depth of field you want to achieve. Canon's manual mode is pretty simple to use, too.

Some would say too simple...

Others would say just simple enough.  Smiley

Also, I'll second that yes, compared to a camera like the HFS21, the XA10 should be able to produce an equal or "greater" shallow depth of field, if you're into that sort of thing.  Wink

The essence of cinema is editing. It's the combination of what can be extraordinary images of people during emotional moments, or images in a general sense, put together in a kind of alchemy.
