Comparison between native 24mm & 3rd party Emolux Adaptor ($30 new) + 52 - 55mm step up ring + Oly 0.7x wcon ($80 used)

With refer to the user manual (pg 90).
http://service.us.panasonic.com/OPERMANPDF/DMCLX3.PDF
For better performance, the Wide conversion setting is set to "ON". But During this test, this option was set to "OFF"

Only resize done, no other PP for all photos.

This test is done with aspect ratio set to 2/3, F2.0, 1/8sec

Although there's vignetting, I would say that the corners of the pics are still reasonably sharp...

Actually, if you change the aspect ratio to 16:9, it's even wide but have to forgo the height. Have tested the function "conversion" setting inside the cam, seem like it does not performance better when that setting was trun off for this mini test.

So there is a difference when we switch on or off for the conversion mode. Where did you get the wide angle len from?

Me and my friend (denniskee) did a test with the conversion "on" and "off" using the 3rd party wide con, seem like when set to "on", the pic seem soft compare to "off" setting. Will upload some sample pic on the later thread. For the mean time, you can refer to his thread http://www.clubsnap.com/forums/showthread.php?t=477934&highlight=wide+angle+converter for more information on some Wide con.

We are using the Olympus 0.7x wide con

Saw the thread you mentioned. In my opinion, it seems like the Olympus 0.7 wide con has better quality.

Looking at this test, Peterpan1975 & me might have made a mistake of not using manual focusing. under low light condition (coffee shop infront of BenPhoto at peninsula), with the wide con attached, it blocks the AF asist light, so the 2 photo we took than may have different focusing distant, resulting in what we thought is the result.

too bad, those who has the Panasonic DMW-LW46 original wide con doesnt want to contribute,:dunno:


pls see this site review for the LUMIX DMC-LX3 with DMW-LW46 original wide con.

http://dc.watch.impress.co.jp/cda/review/2008/09/03/9133.html

what i can see, though not a direct side by side comparison :

1) there is no vignetting when using DMW-LW46 as compare to Oly 0.7x wcon. Given the fact that LW46 is 0.75x conversion, resulting in a minimum of 5degree tighter in diagonal angle of view, so if one crop the image taken with Oly 0.7x wcon to one that has the same angle of view, result may be very similar in both cases.
2) the corner suffers similar degree of image degrading as the Oly 0.7x wcon.
3) not sure how much the in camera WCON-Compensation affect the image quality since this site didnt do a comparison. all images shot were taken with the compensation turn on.
