    Personally found it to be blocking the flash, which is bad when i do indoor macro, especially up close where the object is on a table and i'm taking top down.

    expert here mentioned abt the difficulties in comparing high pixel camera with lower pixel camera at lower resolution..

    Hmm. Maybe our next test will be all the cameras runn at their max resolution. Problem is that resizing may introduce new problems...

    We chose 1024x768 comparison as we felt that it's one that most cameras have.

    Don't notice any except the shadow cause by the can itself.

    This is what i mean in macro mode.



    Also, another flaw is that the extended lense will block the path of the flash, which makes it nearly impossible to take shots of a fast moving nature. Flash is needed when a need to take fast action, like a dancer in motion, but the lense adapter blocks out half the flash effective light, mainly to the right of the camera, resulting in a under exposure of the pictures. AiAF beam seems to be blocked, which means AF speed in dark condition is compromised.

    The supporting example.



    Notice the right side of the picture being under exposed?

    hi guys, some 'fun' shots from me...





    Too bad it isn't focused well.. maybe it's my shaking hands.


    comments?


    ps: if you can't see the pics (some problem with tripodasia) then can go to http://welcome.to/jammers under the Pics.

    Anyone can recommend a free, reliable server that can do external links?

    The lens adapter is certainly useful, but the flash problem is really annoying.

    How could Canon design it without any thought of the shadow caused by the adapter? Also, we can't add an external flash, so looks like no way out of this.

    Can only use the adapter in non-flash shots.

    I wonder can complain to Canon about this or not?

    It is normal the LCD screen look noisy (pixel running around)
    when
    1. the surrounding is light is low, eg nite shot.
    2. the surroundng is bright but the dark area is noisy, eg dark
    brown door with light blue colour wall.

    Final output and preview does not look noisy. If taking movie clip, it will look noisy like the LCD screen.

    Does anyone have similar problem or mine set got problem?

    the lens adaptor shadow thing is a known problem even for the G2, and G2 users get around it by either zooming in all the way, or using an external flash. It's kinda demanding to ask for no shadowing, at the same time wanting a good flash and compact body. If the cam is designed to fit a lens adaptor without flash shadow, the internal flash would have to be much higher, thus compromising the size of the body.

    Rather than complaining to Canon (which prob can't generate much useful feedback for you guys), maybe you would like to try the following:

    1) When you want to use flash, take out the lens adaptor. Since for most flash shots, you won't really need filters like UV or starburst.

    2) When taking macros, don't use flash, either use artificial lighting if not enough light, or use long exposure (with tripod).

    3) Get an external slave flash, which can be triggered off by your A40's internal flash.

    That's all I can help....flash shadowing is indeed an irritant but it occurs for almost all compact cams with protruding adaptor. My c700uz has flash shadowing too at the widest end (38mm), but zooming in a little will get rid of it.

    Default Shot with +4 close-up filter

    Macro shot with close-up +4 filter. A bit better than stock lens, but still not great.

    Default Hoya Close Up +4 Filter

    Hmmm.... for me the close-up works well. Lets me get closer.

    This photo was as close as I can get with macro (without +4 filter):




    This photo with +4 filter:

    It is still about 16cm to be able to focus. But the picture is magnified.

    I would say the close-up filter is like a magnifying glass.
