    I played with my new X-E1 & 18-55 yesterday after updating the firmware of both camera & lens (1.04 and 1.01 respectively), and found results when using manual focus mode to be quite poor.

    If I used the rear AE-L/AF-L button to focus, it would lock on but the displayed distance would be way off; i.e. 15-25 ft. for something 4-5 ft. away from me. It would also not be sharp.

    If I manually turned the focus ring, it seems I can dial out to infinity and beyond (he he) and still not get something 20 ft. away to be sharp.

    It seems that when using "S" auto focus with this lens, it produces a sharper image and can (somewhat) correctly focus on things at different distances, although I'm not yet all that impressed with how sharp it is.

    This was all at dusk and indoors - is there a focus issue in low light? I haven't had a chance to get out in broad daylight, but I normally shoot blue hour / golden hour light anyway.

    Does this all seem normal, or do I have a bad lens? I can post my camera settings if necessary. I might be able to post some of the test shots later, after work.

    I would try to re-apply the firmware, but it seems that isn't possible.

    Hi Kev,

    As far as I can tell, the manual focus ring appears to operate when the focus switch is set to "M." Have you been trying it when at the "S" setting? Just want to be sure I understand how you're operating it.

    If so, the X-E1 may have a "AF-S + M" mode, but I'd have to read the manuals and/or dive into the menus to see if that's available.

    My X-E1 and 18-55mm does quite well in low light:

    I haven't had to resort to manual focus, so far I just point at something with a bit of contrast at the depth I want to be sharp, press half-shutter, re-frame and take the shot. For grins I've tried manual focus while out at dusk, and I didn't seem to have problems. Later I can look through my exif data to see if there are representative shots like that.

    My images have been really sharp so far ...

    I don't think I've tried using the focus ring while in "S" autofocus mode. These have all been in "M" manual mode (focus mode selector dial on front of X-E1 near the lens) using either the focus ring or the rear AE-L/AF-L button.

    Here are original SOOC shots.

    The sunset shots from yesterday were handheld from inside parked car, with OIS on.

    The midday shots from today were tripod-mounted with OIS off.

    OK, here were two manual focus shots tonight with the 18-55mm:

    Long-end (53mm), 1/30th second, f4.

    Focus was on the window and lights on the house across the way:

    Focus was on the utility pole:

    So, no problems for me grabbing manual focus (focus switch was set to "M") ...

    Woh! Somethings not right there ... Is there a "Complete Reset" type of menu option you can try? Also, try re-seating the lens ... Ehm ... shucks, I hope that doesn't need to go back, but it might.

    I haven't tried a camera reset yet, I was hoping to re-apply the lens firmware but I'm not finding any way to do that. I have removed the lens numerous times, even gently wiping the contacts, but it doesn't seem to change anything.

    I'm off to find out how to reset the camera. *edit* Found it, did it, but it doesn't seem to have made any difference.

    Sorry to hear that - unless someone else can chime-in I'd say it needs to back. :(

    Update - I'm sending the old kit back, it's definitely not working right. In the mean time, I couldn't wait and already have my replacement and IT'S SHARP SHARP SHARP! Finally! Third kit is a keeper.

    OK, Spring, I'm ready for you now.

    YAY! Glad to hear that. Congrats, and hope you get a chance to shoot a bit tomorrow. I hope to get out near dawn for some good light. :)
