Which lens and where? 

the leica 25 mm, its on a local photography magazine. Gave it a solid 8.2

I hope you gave us a mention. :-P

I actually did!! I posted a link to the samples thread.

single photo 7.5 x 5.5 feet print from the gh2. No jaggies or artifacts to be seen even when viewed at an insane distance of 3 feet away. it can be do be done people, no 40,000$ camera required, just careful editing and proper resizing. Put that in your hasselblad and smoke it!

Some sort of bicubic interpolation has to be used otherwise things will look ugly. Smartedge 2 is free (beta version) and does a fantastic job (better than the paid version of alien skins blow up), but its a bit hard to find sometimes. Photoshop's bicubic smoother when resizing also does the job but its not as consistent with complex edges (but it works really well). Its quite a feat for any computer, so be sure to have any other program/aplication closed. Even then itll take a while. Sharpening HAS to be done after the resize and not before, otherwise youll get halos to no end and moire. So its RAW conversion with sharpening for lens, resizing with no sharpening and then sharpening. After the resize youll need a slightly bigger radius in the sharpening process than what you would normally use. Check for noise and/or artifacts (remembering that luma noise is not nearly as apparent in print than on the screen) and youre done!
the finished size was 27648 x 20736 at 315 DPI (which comes to about 7.4 feet by 5.42 feet. And it wasnt even at ISO 160, it was at ISO 400. I cant stop staring at it, its wonderful, I didnt think it was possible without looking super soft or with jaggies. I dont even want to deliver it. I just did with m4/3s what I didnt dare ever do with APS C...

Sounds fun, if you do Ill resize an image to that size and post the 100% crop and procedure.

Ill post a sample when i wake up

Lisandra as always and even more so now i'm very impressed by what you do with m4/3 and photography in general! Thanks for posting

i want to read it

Highlights:
While the purpose of the review is certainly not to pit the leica against the 20mm pancake, its hard not to compare these seemingly similar lenses. I mean, for 399$ or so you can get a lens that's almost as fast and has a bit shorter focal length, Is the leica worth the extra money?
The first obvious thing to note is that the leica is not a pancake, not by a long shot. Its not huge either, its about the size of the 14-42mm. The design of the leica is a bit more complex than the 20mm, coming in with 9 elements in 7 groups, while the 20mm is 7 elements in 5 groups. So, are they different enough? Yes. Simply put, the slightly larger aperture combined with the slightly longer focal length makes for a dramatic change bokeh wise, even when you match the 20mm's image to the 25. The difference can be easily seen in the samples.

Optically I deem it worthy of the leica brand, it might not be a resolution monster stopped down like the 45mm macro, but it makes up for it in one very important area: wide open. Ive used quite a few fast lenses in my short life, and this thing wide open simply shines above all. Things do get better when stopping it down, even as little as 1.6, being its sharpest at f4-5.6. BUT, according to the lab tests using imatest, when both of them are stopped down (the leica and the 20mm) the 20 mm is sharper. So, wide open goes to the leica by quite a margin and stopped down to the 20mm.

Focusing is fast with the GH2, definitely faster than the 20mm, and manual focusing is also better. Thats not to say that focus by wire isn't still a nightmarish affair, but there's a bit more room to do things on the leica than with the 20mm. To this reviewer's personal taste, the focus ring is simply to soft, and makes manual focusing at f1.4 (sometimes a necessity)  extremely frustrating.

Is it worth the money? that's up to you of course but I will say this, its fast, sharp wide open (a rare thing, believe me), and not super expensive for something with the leica brand. It doesn't get a 9/10 because of the manual focusing and it doesn't get a 10/10 because as sharp at it is wide open, stopping it down it doesn't improve dramatically like other primes. I recommend it
