    I own both and - after purchasing the 23 (as second) - I've run a brick wall shooting test. Which I hate to do, but in this case I was very courious to see the IQ difference.
    To my surprise, I verified that they're really very close, and the only remarkable differences I could notice are @f/2.8 and in the outer regions of the frame.
    I almost regretted purchasing the 23....

    Surprise to see a cheaper lens wide open better or same than a fast prime stopped down two stops (from f1.4 to f2.8).

    I think you misinterpreted his remark.
    It seems to me the 27mm is not the best wide open, but stop it down and it's a very good lens. So between f/1.4 and f/2.8 definitely a properly aligned 23mm should outperform the 27mm. For me I'd say probably until about f/5.6 the 23mm is the clear winner if sharpness is what your looking for. Not to mention the huge difference in handling. You always pay a lot for wide aperture quality and build quality.

    The 27mm doesn't outperform the 23mm at 2.8, that's for sure. It isn't the sharpest at f/2.8, but then, light gathering and shallow DOF isn't really the main focus of the lens.

    If you only care about resolving power then the 27 is a better lens.

    But it has other issues, like field curvature.

    Anyway, here's the resolution details.....

    From photozone.de read the full analysis, don't just rely on MTF.

    I was actually meaning the opposite ;)

    But anyway don't expect major differencies.

    For the price, the 27mm is a stellar lens, especially if you got it on markdown like a bunch of us did. The $200 it cost me definitely gives a very high price : performance ratio. Not sure I can find a single other lens that I would say gives that kind of ratio, even though most other X lenses are also stellar performance, the low price weighs heavily in its favor with me. Agonizing over the new 90mm as that may be out of reach for a very long time.

    I think I made up my mind :) Get 27mm first, and when I have extra cash trade it in for 35mm.

    Great post!

    Get both now! B&H has the 27, 35 and X-Pro1 for only $949! Buy that package, then sell the brand new X-Pro1 and you'll have both lenses for the cost of 1.

    Thread resurrected! :p Apologies in advance - ;)

    I'm in this same boat as the OP but with the *new* 23F2 and the 27mm. I already have the 27mm and am very curious what the 23F2 would buy me beyond an additional stop of light and quicker focusing. I'm an amateur picture taker (notice I didn't say Photographer). I'm not certain the new lens would be advantageous for me. I'd be curious about your responses if you felt so inclined... Thanks good folks!

    Wider field of view, and more important (at least to me), an aperture ring!

    As technical matter, a newer design with better optics (similar to 35mm F2 which I have), weather sealing and most importantly, an aperture ring. I would get the new lens just for the aperture ring and the convenience it offers me!!!
