I have a WD-58 0.7x58 wide angle converter. Any XA10 users know if it will fit the that camera . . . ?

Hi Ron,

The XA10 handbook quotes the w/a converter as part no WD-H58W. I don't know what the consequence of the "H" is.

Thanks for that Glyn. It's not certain, eh? I'll have a look at the European Canon Customer Services to see what they say.

Okay. Fed-up with trying to get an answer from Canon Europe.

Anyone know . . . ?

H = high price LOL

The WD-H58W is a much better piece of glass than the standard 58 w/a converter

Will it fit? Probably not Ron, but you can hold it up in front of the XA10 and if the image looks to be what you want you can go out and buy a 46>58 (whaever) step-up ring.

The "H" lens is better than the cheaper version

The 'H' means designed for HDTV. that means the circle of confusion is designed to match the much-smaller pixel size of the HD camera. So you should get sharper pictures with more contrast than when using a non-'H' adaptor.

Alan,

As a slight aside, why does the 'H' range give more contrast? I can understand the higher definition achieved as the sharpness is no longer optimised to reduce artifacts at SD, but does (effective) contrast improve because of a sharper image or is it just better lens design that reduces reflections and flare to improve contrast?

Both. the increased sharpness comes through better control of the surface grinding, and through better surface coating. That reduces the dispersion, and that, in turn, reduces the amount of light not contributing directly to the image. And that means less light rattling about, which means less flare which means better contrast.

So it seems that the 'H' version is better quality overall, like the 'HG' WA lens I have for my HC3E.

Thanks for the explanation Alan.

Yes, that should be the case.

Thanks everyone for those contributions and especially Alan.

I'm now much better informed but less satisfied . . . !

The zoom-through will have three elements so robs you of contrast however expensive it is. It'll also increase the barrel distortion - something you may find acceptable out in the fields but will make cathedral interiors look a bit bendy.

That latter I've noticed in the past, Tom, and not only with cathedral interiors!
