    P vs P+ ..what's the diff?

    I am researching Phase One backs.

    I am looking at a Phase One P30 and a P21+ . Both of these backs are selling for roughly
    the same amount of money. Besides the difference in resolution, what is the difference?
    The capture time seems to be roughly the same. Is there a reason why the P21+ would
    sell for the same price as higher resolution back?

    Which would be a better buy?

    Re: P vs P+ ..what's the diff?

    The big difference is the sensor one is 9 micron which is the same sensor in the P25 plus but with Micro lenses. The P30 Plus uses a 6.8 Micron sensor


    P 21+

    Imaging technology
    CCD: Less than full frame CCD
    Lens Factor: 1.3
    Resolution: 18 mega pixels
    Active pixels: 4904 x 3678 pixels
    CCD size effective: 44.2 x 33.1 mm
    Pixel size: 9 x 9
    Image ratio: 4:3
    Microlens on CCD: Yes
    Antiblooming: 10 f-stops
    Dynamic range: 12 f-stops


    P 30+

    Imaging technology
    CCD: Less than full frame CCD
    Lens Factor: 1.3
    Resolution: 31.6 mega pixels
    Active pixels: 6496 x 4872 pixels
    CCD size effective: 44.2 x 33.1 mm
    Pixel size: 6.8 x 6.8 micron
    Image ratio: 4:3
    Microlens on CCD: Yes
    Antiblooming: 10 f-stops
    Dynamic range: 12 f-stop

    Allso the P30 plus is rated 1 stop better at ISO 1600 compared to ISO 800 of the P21 Plus. The P21 Plus is a faster capture back at .8 seconds and the P30 plus is 1.25 capture rate.

    So technically they are similar but do sport different sensors

    Also here are the PLus series special features. I just pulled this part off there website but the Plus does have a better brighter LCD. There are more features but I can't seem to find the comparison page they once had up between the NonPlus and the Plus. I myself have a P25 Plus

    P+ SPECIAL FEATURES

    1 Hour Exposure - The patent pending XPose+ technology enables noise-free exposures of up to 1 hour. Create fantastic images using extreme light painting or capture great architectural designs at night time.

    Live Preview - The scalable focus window supports an effective workflow on large production jobs between the photographer, the art directors and the stylists.

    Level Meter - The unique and patented high precision level meter ensures a perfect horizontal setup.

    Extraordinary color reproduction - Opticolor+ is a unique image processing algorithm delivering high color accuracy in deep shadows and perfect skin tones.

    Noise-free capture - The Dynamic+ technology ensures less noise at all ISO settings and break limits on the ability to work in very low light.

    Efficient workflow - Capture One is Phase one’s RAW workflow software. Capture One provides an efficient workflow and handles the processing of all RAW files, delivering optimized image quality. You can read more about Capture One here: www.phaseone.com/4

    Where do I call up the level meter in the menu?

    i believe a major difference between the plus and non-plus versions is that the plus provide live view

    Jack,

    I'm trying to find it myself. I'll research it and let you know what I find.

    Chris did I miss something in the comparison by chance. I remember Phase had on there website at one time the actually differences on a chart and I can't find it anymore and this question does come up a lot.

    That is true. Just remember that live view can only work when tethered.

    Currently the level is only available when using Live View tethered to a computer. The on-back bubble level has been discussed for quite some time for the next version of the digital back firmware for existing + series backs, but no ETA or details.

    There was also some discussion that the P65+ would ship with the bubble level firmware. I don't know if it made it into the production units which are shipping at the end of the month.

    Now that's just plain stupid... If I'm in the studio using live-view, I can certainly tell if I'm level. The real need is in the field when not tethered!

    Re: P vs P+ ..what's the diff?

    I'll add my voice to those who would love to have a level indicator feature available on the un-tethered back. I use a hot-shoe-mounted spirit level most of the time (when appropriate), but it would be handy to have one available on the LCD.

    And I agree with Jack's sentiment above.

    Certainly you won't see me argue that point.

    Ditto. Would be a great feature, especially if the hardware to make it happen is already present in the back. Seems a bit silly not to add it as another viewing option on the back LCD.

    Slightly off-topic, but my wish-list item would be live view displayed on a large panel on the back. No need for an external computer, and no need for a sliding adapter; in fact, no need for a prism or mirror, either!

    Do you guys know if anything has been discussed in this area?

    After digging, I found a thread on LL that goes some way to answering why we can't do this at the moment.

    Please excuse my laziness
