    Very nice indeed - it appears to be slightly sharper and render colours slightly more saturated than the 20mm.... hope the Oly 45mm turns out to be as good as these two lenses....

    You know in looking at those images it seems to me that they are almost too close to call. I agree the Leica seems to render a bit more saturated but I think sharpness is a tossup.

    Hmmmm. Need to see more. I am a little concerned that I detect some of those slightly ethereal things about the 25: tone, character, warmth, contrast - that are significantly different than the 20.

    This does not necessarily mean better, just different. Same camera and settings, yet a different feel.

    This concerns me because I find the character of the 25 attractive, and I don't want to have to buy it.

    Anyway, much more comparison needed.

    I saw this earlier, but it didn't help convince me to pre-order the PL25. It is certainly has shown to have a desirable bokeh quality (to me) from most of the samples online.

    But that pic of the guy.. seems unfair to the 20/1.7, seems like it's at a slightly different angle.

    Need more samples =) and an AF review. I don't think the 20/1.7 is all that porky, but faster and silent might actually be worthwhile to add.

    The photo of the guy is a bit unfair, but some of that difference just has to do with how much closer one needs to get to have the same framing. The 20 can have a much wider feel, which is one reason I like it so much, but not so great for head/shoulder portraits unless you want that very close perspective.

    I agree that the portrait with the 20/1.7 was a fair comparison because of the angle. The PL25 does show a little bit better sharpness. As expected, it has a shallower DOF, and the bokeh is a bit more creamy, IMO.

    Any size comparisons of the lens themselves? One of the best assets of the 20 is the size. I hope the PL25 is not more than 2x the size of the 20.

    I can think of no better way to pit Micro Four Thirds owner against Micro Four Thirds owner! :wink:

    I don't know of a direct size comparison, but based on the comparison shown to the 14/2.5 and 14-42 at CNET Asia, I'd say the PL25 is just about 2x the size of the 20.

    I should add though, if the oly 12/2 proves to be as good or better than the 20/1.7... I will probably buy it. And it would pair w/ a PL25 for me much much better =) And if the 45/1.8 is also as good... I will be a very very happy m43 camper.

    Indeed, I was all set to get the 20/1.7, but now I am seriously considering the 45/1.8 instead. I'll have to see test shots first... but the rumoured price is attractive ($300). What I am debating is which FOV I would prefer, and how much I would really take advantage of the smaller size of the 20.

    Instant classic

    I own the 4/3rds equivalent to the PL25 and they seem to speak to each other... the new one may be slightly sharper with a touch less CA, but retains that overall softish/warm character that draws you in. I also find the new PL25 and the 20/.7 to be very different in that regard, at least from samples of the former to date (I think the creamy bokeh reinforces that perspective).

    Unreal rendition capabilities.

    Bokeh D


    The 4/3rds PL25 becomes clinical with a CP filter....

    Not having the 20/1.7 (my GF2 kit came with the 14mm), I figured I may as well order the PL25 given that at Henry's it was only another $140 or so... I'm not sure where I am in the preorder list but as soon as I get it I'll post some shots :-D

    1) I can't believe it :eek: They dared the brick wall!
    And yucch... to make it worse, the sky is overcast? You can't learn or conclude anything from such shots. This is not a lens target, it's just a bore. And it casts a doubt on everything else: is the cameras stable, the focus double-checked, the exposure consistent?

    2) Excellent illustration as to why shorter lenses tend to make caricatures out of portraits. Next lesson will be about the fisheye...

    3) Surely informal shootout... Looks like the credits screen in a late, not to say senile, Bergman movie.

    However, it does point to some information about the Leica lens:
    • a. The blurred picture frame on the wall has double edges
    • b. The round highlights on the table edge exhibit double contours too, and their edges have distinct red and green outlines.
    • a+b= this kind of bokeh is certainly not ideal, and I find the Panasonic's less disturbing, as in more natural, even taking in account the change of scale.
