    You got that right 100%!! Its all about being easily able to compose.... although live view for focus is still very viable for me.....

    So one problem I'm having with LV is it seems to pause without any feedback - have to touch the screen to get it working again. Normal?

    Also have to change the power saving setup or the screen keeps turning off. Seems it should ignore the screen time out settings whe active.

    The 72mm Schneider is a great lens on any Tech camera. Compact and decent image circle with little or no distortion.

    Wayne,

    I have my back set for screen power down at one minute. This, to me, is long enough as live view eats up batteries too quickly. I use the Disto to get me really close and check with live view..... this really is only for a few certain images as the Disto is so accurate that I find live view too slow and too power hungry. Composition, though, is fabulous with live view and doesn't require much time! I also don't have any pause issues.

    this may be too geeky, but where do you set the base (zero point0 of the disto when measuring?

    I add 0.02 feet To the zero point in the menu settings (sorry - I have the hpf rings in feet). Then with the 90 degree base plate flipped open I position that up against the back of the STC. Since I don't have a viewfinder I can put the disto right on top of the camera. I estimate the distance between that part of the camera to the sensor surface to be about 0.25 inches, hence the 0.02 feet.

    Yes, I changed mine to 1 minute, although I prefer it shorter for anything other than Live View. As I mentioned, seems that LiveView should ignore that time since while you are in live view you obviously need the screen on, also should be a more obvious way to turn live view off when you are done. the time out doesn't actually disable live view, just the screen. The green light is still flashing, so it's still eating up battery power until you turn live view off.

    My real problem is the screen seems to freeze. I'm trying to focus and suddenly see no changes, I can even move the camera and see no changes. Touch the screen a pause icon flashes briefly then it begins to work again. At this point LV is totally unusable. I have no clue what purpose pausing the live video would serve... it certainly should only pause when I want it to and make it obvious on the screen that is was paused.

    I was just hoping I was missing something ...

    I've cobbled together two cheap 77mm non circular polarizing filters as a variable ND and it works fine in bright daylight at f 16.
    Hi Woody, congrats on your IQ180. As I understand it, these are your steps for using the IQ180 for composition using live view:

    1. Eyeball an initial composition, choose your lens focal length and orient the camera as a first guess.
    2. Mount a variable ND filter to the front of the lens.
    3. Capture live view with the IQ180 and adjust the setting of the ND filter until you can see a decent image.
    4. Now, you adjust the camera orientation to get your desired composition.
    5. Focus your scene using distance measurement with a Leica Disto.
    6. Remove the ND filter.
    7. Measure an initial exposure for the scene and take the shot.
    8. "Work the composition", by re-mounting the variable ND filter and repeating steps 3 - 7 for each new composition.

    I do not doubt the value of the live view feature of the IQ backs, but I find the repeated re-mounting of a ND filter to be a hassle. In the field, I almost never get the composition right on my first attempt, and am never sure of which composition actually "works" until I am analyzing my various captures on a computer. So, in general, I need to shoot many times from many different angles and positions, changing often from landscape to portrait orientation, etc. The thought of having to put a ND filter on and off between different compositions sounds painful to me.

    I prefer the iphone solution myself, at least for composition, as it is much faster to test the different possibilities in the scene. The need to work quickly is often critical. For example, the available light in a landscape scene is somewhat "short lived" and fumbling with a ND filter may lose potential compositions.

    Re: IQ Series Firmware 1.33 Released w/ Live View

    BTW, I believe my issue was a low battery. Replacing the battery and no more pauses. Put the old one back in and the back struggled again.

    More optimistic ... focusing was actually pretty manageable, and composing in conjuction with the iPhone viewfinder was terrific. Have to try it for real over the weekend, although I'm still not sure I can live with the lens cast on my 35xl.

    was working in normal "evening" light, and didn't need an ND filter.

    David,

    There really is no need for a ND filter for composition..... just stop the lens down. Use the Disto for distance checking and set your HPF ring and you are done. If, however, you are using Live View for focus then you may, or may not need a ND filter. I have not needed one except for very bright scenes.

    Ah, I see now. Once you have chosen your focal length, then you can fine tune your composition by just stopping down the lens in live view mode. Yes, this is indeed very useful. But, I still like to use the iphone for "walking the scene" and determining focal length selection without having to lug the tripod setup around to see if the shot will work.

    I am very interested in the live view and will get a chance to test it in the near future. My use would be on a tech camera.

    In the meantime a few questions for those of you who have the camera and will have more time to test it and in a variety of situations:

    Since live view would be very useful in shooting interiors, I would like to know how it works in LOW light, not just bright light. What is the limit on how low a light illumination level it can be used with??? No one seems to have mentioned this. Does the gain of the image cause it too become too grainy, especially when stopped down in low light? I am comparing of course to a 5d2 live view which is phenomenally useful in low light, making focus much more accurate than using the viewfinder.

    What about gauging the sharpness of a tilt or shift at the edges of the frame? And for that matter, the depth of field.

    Thanks
