    The only close-calls I've had with RRS clamps have been with the screw-type, and always because I thought I had it seated correctly, but did not. Working in the field in awkward positions, with cold hands, etc., I have "skewed" the placement and the clamp pinched just the "rim" of the seat.

    With the lever I have better feedback as to whether it is seated correctly. IMO both are good, and both require that I pay attention (easily said, but not always practiced by me).

    I tend to shoot a fair number of vertical comps, and often shoot a scene horizontally then look for something vertical I can use from the scene (or visa-versa), for which the lever style clamp is a life saver. And further, I prefer the way the RRS lever tucks under the Mamiya body. Really I like both, but I do find advantages to the lever-type at times as well. I just have to be careful with either.

    Re: Medium Format Pano's

    I just picked up the RRS BH-55 LR. When I called them and told them what I was looking to do, the suggested that the lever was the best bet. The said that sometimes the twist lock can not be fully tightened and the plate/ camera could slip. From the other posts that I've read... they might be correct. I have to say the build quality of this head is top notch!

    I'll have a better idea how it truly works in Carmel / San Francisco this week.

    Re: Medium Format Pano's

    the only problem I encountered using the RRS slider is that the slider clamp to the camera is meant for a left-right oriented camera plate, which is what RRS provides for the mamiya, M2 and dslrs. for the Blad and Rollei, though, the camera plate is front to rear. the plates are not made to be rotated 90 degrees, as they rely on the camera edge as an anti-rotation method. I had to stack another camera plate at right angles to the F-R plate! but it is tidy and works

    John:

    If you buy the basic plate -- MLP 1 I think -- then the little $5 stop, then the clamp of your choice, you can mount the clamp on the rail in either direction for fore/aft or side/side attachment of the camera.

    First real work with my Cambo RS/P45/35xl. Feeling real good about the kit but have a lot of learning to do.

    Anyone care to share their focusing routine? The calculated hyperfocal distance doesn't seem to give sharpness to infinity.

    Hi Ed:

    Nice pano! You might want to use the LCC tool to prevent the magenta-green color casts that get imparted with the lens shifts, though they look kind of cool in this shot

    As for DoF with medium format -- I say use a two stop lower hyperfocal for the actual aperture. IOW use the f11 hyperfocal for an f22 actual lens setting... Or consider focus stacking.

    Cheers,

    Re: Medium Format Pano's

    an issue with the lever clamp on the cube is that it has a minimal range of travel, so if you set it to grip well, it doesn't open very far and as you have so slip the camera base plate in from the end it is fussy.
    the screw clamp from RRS will open far enough so you can drop the camera plate straight down into the dovetails. much nicer

    This is not the case with my RRS quick-release clamp. If I open it to 90 degrees, yes, I have to slip it in, but if I open to 180 degrees, it drops in vertically. Is yours different, or is it somehow Cube-related??

    The Arca clamp that came on my cube opens all the way if the ribbed metal latch is pulled back with the thumb.
    Plates then are easy to get in or out even sideways.

    Re: Medium Format Pano's

    Mine will move about 180.
    First stage lock:
    Round sliding button on side of lever unlocks for the first 90 degrees.
    Second stage lock:
    look at the lever surface that is now newly exposed. There you will see a serrated pin that connects the sliding button to the lock. pull that pin out just a bit with your fingernail, and the lever will open the remaining 90 degrees.

    Re: Medium Format Pano's

    John:

    The other option if you want to stick with the Cube clamp --- that lever is Delrin and easily machined. (To remove it, simply loosen the jaw adjustment wheel all the way until it slides out.) I re-contoured the cam surface to a larger flat at the 90 degree stage. This allowed for an easier in and out of standard plates.

    IMO the gold fix would be a longer shaft and adding a washer and small o-ring a-la the RRS clamp

    Jack,
    With the current lever design, that is not necessary.
    The double catch allows a bit of safety as well as the convenience of complete opening.

    Understood, but I think it can be improved upon and who better than John to do that?

    Guys you have inspired me to try this.. I have a heavy duty CF Gitzo tripod, I can't afford a cube now what would you recommend as a kit? I have a Sony a900 with a CZ 24 -70 or G 70-300. I will purchase APP.

    I like the RRS BH-55. The pan base locks very solidly (good for using off-axis or horizontally) because they employ a tension strap design, instead of the common set-screw type of design.

    You could get by with a lighter head than the BH-55 also, such as the BH-40 or Arca-Swiss ball head, or Acratech as offered above. I prefer the pan base on the RRS (BH-55 head, but these others are strong enough for you kit in terms of weight.

    Re: Medium Format Pano's

    Mike,
    If you want to do panos with a BH-55, I would recommend topping it with an RRS PCL-1 pano clamp. I use it on top of my gitzo head in my light-weight setup. If course, it is not as easy to level as the cube, but it is usable. It is important to level the panning element most of all, and a ball head helps with that.

    Re: Medium Format Pano's

    I thought about mentioning the PCL-1 also, but not knowing the budget thought I let it trickle into the conversation. I get by without the PCL-1 by taking extra time at setup, but after trying one have planned to add it also. I just tend to take some long hikes at times and my kit is already rather heavy.

    The PCL-1 plus an additional dovetail mount allows for a quick setup. Or one can forgo the "normal" RRS clamp and use the PCL-1 as the clamp (rather than the lever clamp or screw-type clamp).

    Good call, Bob.

    Re: Medium Format Pano's

    I seems I need a ballhead because the one I have now is the RRS 25 for the M8, and a L- bracket for the camera, ball-head, PCL-1 with dovetail, and a RRS rail to set the nodal point...correct?

    Re: Medium Format Pano's

    For single-row panos, yes. Btw, you only need the rail if you will work with things close up. For landscapes it might not be necessary. For multi-row panos with things close up, you will need the full pano kit, not just a rail.

    Re: Medium Format Pano's

    Mike,
    You can order the BH-40 or BH-55 with the PCL-1 pre-installed as the top clamp.
    I would use a rail usually, since the nodal slide is more an issue in a three dimensional scene. The dovetail piece is needed only if you want to use a regular clamp as well as the pano clamp. I keep my pano clamp mounted all the time.
    I don't have a full pano kit, since I don't do VR and prefer to use a wide-ish lens and a portrait orientation to the camera to avoid as much geometric distortion as possible.

    the acractech clamp is completely functional with any of the RRS dovetails. I used it with right angle brackets, camera plates, pano rails and the pan head.

    Re: Medium Format Pano's

    You can do without it if your subject is pretty much in one plane and relatively far away.
    If your subject contains tree trunks in the mid or fore-ground, for example, then you will find the nodal slide to be beneficial.

    This might not seem to be a very exciting image on the surface however it represents my first multiple image panorama using the Cube and Novoflex combination.

    4 shot image, Phase AFD, 75-150 lens came out to 51x17.

    Now to find a better location to shoot!

    I wanted to test the limits of both the Cube and RS this morning so I did a test. Standing in my backyard I put the RS with a 72mm lens attached onto the Cube all attached to the tripod. I leveled the RS using the Cube then began taking images from left to right beginning at the furthest point at 20mm working my way right at 10mm increments for a total of 5 images. I opened the images directly into Bridge and photomerged from there. I didn't do any LLC or other type of post processing although looking at the images color I know I needed to. What I was looking for was the type of image I could obtain doing what I did; if I worried about the content I would have gone somewhere else.

    What I found was that I can produce a single row panorama using the Cube/RS combination at measures 16.64x43.553 inches. I know I can do multiple row/column images with the RS so the next test will be using the Cube/Phase AFD along with either my 28 or 75-150 lens and will try a multiple row/column merge.

    I want to try this out prior to meeting Ken next month in Canyon de Chelly.

    Re: Medium Format Pano's

    just completed a two row by 3 column shot using a combination of the Cube and Phase AFD along with a 28mm lens. I found the markings on the Cube to be very friendly and returnable shooting the first row then moving upwards to the second row. Again while this might not have been the greatest subject matter I can see where the Cube can be used to do multiple row image merges.

    Here's two sample images:

    The first just after it was merged while the second shows what I feel is a usable crop. No post processing has been done as I wanted to leave it as it came from the camera and yes I can see the dark streak in the sky right of center. The object of this was to see if I could obtain a multiple row/column image using the Cube and I proved to myself it can be done.




    While I think I proved what I set out to I also proved (at least to me) that you just can't beat a technical camera for flat multiple image stitching.

    Gotta run
