    No, quite opposite, because of the smaller needed flange distance of the "tele" designs you (once you position on the same place as normal 240mm which is further relative to it's design) you will be focusing more closer, giving you more of a "portrait" approach, as it was intended.
    Originally on these machines there were tapes for measuring
    Enjoy your camera! I just did the 1st shot with it yesterday: https://www.flickr.com/photos/milosg...posted-public/

    I have the Big-Shot rangefinder on mine, it works great! Way faster and easier than the tape-measure. My 2 of these came with a Tele Congo 240 (which is NOT a tele lens, despite the name - it's a tessar) and a G-Claron 240/9. I haven't tried the G-claron version yet but the Congo version is nice - great tessar bokeh, as expected.

    I have thought of fitting other lenses and redoing the rangefinder, considered the Nikkor-T 270mm since i Have one lying around. It would probably be a tighter framed shot than what the 240 offers. Could also try a Nikkor-T 360/8. Both use the same #1 shutter as what comes on the Cambo Maxiportrait.

    Misko, I thought you had several bigshots and were going to cannibalize one for this? Good to hear you got a Maxiportrait at last!

    The bigshot rangefinder has a huge RF base, about 5.5" , so it's perfect for this, and very sensitive.

    I took mine out on the worst possible day - harsh overhead sun

    with no shade around

    this was the only one I got out of all that

    The original f 6,3/240 Tele Congo covers 5x7".

    Hey Ed,

    I have asked over on APUG - how does the Big Shot's RF work? Is it usable for framing too or only for focus?

    Do you think that one you have with G-Claron was originally built with that lens? And I am surprised to learn that Tele-Congo is not of Tele design!

    Problem with fitting longer lenses to the focal point planned for a lens of 240mm is that it will not necessarily mean that the frame will be tighter. Would have to calculate but could be even opposite.

    I do have 3 Big Shots but all three are in different usage:
    1) With cut nose (shutter) and attached new shutter with PC Sync that I use most of the time (a bit wider frame & further focus than original)
    2) completely in factory stage - which I would like to keep "as collector item" and
    3) with focusing flash plate cut off which I use with the flash sync of my creation to shoot with Canon Flash & this one still hase same framing as original (no alterations to the shutter / lens)

    Dr Tang,
    This was not fully opened apertute on the shot you have posted? I can see the shape of the aperture in the bokeh spots in the background...

    Plaubel - that's why many people buy the camera & remove the lens which is very sad!

    MIsko -

    Good to know you have a few Bigshots- it sounds like you need another one you can cannibalize. ;-)
    The 2 I have gotten were under $20 on ebay, I felt a little bad about hacking them up but not really bad enough to not do it.

    The rangefinder is basically perfect for framing too. Between the focal length difference from the original big shot, to the larger format of 4x5, the framing turns out to be pretty much spot-on. A very handy benefit! I was able to recalibrate the rangefinder just using the screws on the bottom mirror for adjustment, no major surgery required.

    Regarding the G-claron one - I am not sure if that was how it was supplied but I believe so. It was in a Copal Press 1 shutter, and I think I have read in Cambo literature that it came with that lens later in it's lifetime. (There are 2 "versions" of the Cambo maxiportrait, the casting and viewfinders differ, and perhaps lenses were always different between them as well. )

    For longer lenses - the Nikkor T 270 would be a tighter shot I think, since it has a lot lower flange-focal distance than the normal congo 240. For the 360T, I think it would be a wider shot (based on the same reasons) but would require some experimentation to figure out. I'll give it a try once I get a chance to see. I thought of switching to a regular Copal 1 shutter too, since the Copal Press 1 only goes to 1/125.

    congo is odd in that they name those lenses as Tele when they are not tele. They are also labeled Commercial Congo too, I think - (maybe like Commerical Ektar?) not sure why - but in general, they only have a couple true telephotos in their lineup, I think 300mm and 400mm lenses possibly.

    keep us posted on your efforts,
    -Ed

    Ed,

    Yes, Big shot is one of my fav cameras out there! I shoot with it all the time. I am continuously looking to purchase one more for this purpose but I cannot justify 70$ for a finder (20-30$ for a camera and 30-40$ for damn shipping to Shanghai). I am really glad to hear that framing of BigShot's finder fits "bigger" Cambo brother too! And yes - I know recalibrating it easy. That's how I did my finder when cut the nose of one of my BigShots in order to install new shutter, which moved the focus further back.

    I am aware of 2 versions of the Cambo. Here in the topic - one present is completely different than the one I have. I am just not sure what does it's viewfinder do? It has 2 panels on the front (one frosted) so I am not sure if it has any purpose except aiming a shot?

    I would love to see some of the examples you have shot with your cameras and especially if you gonna be shooting some tests with Nikkor or 360mm lens!!

    And yes - normal Copal has shorter speeds but needs cocking which can be a tiny issue once you start doing the portrait without a rangefinder. Now that you have installed rangefinder - it is much easier!

    Awaiting my cheap Lomo finder (12$ in total with shipping) and when it arrives I will be adding it to the camera!
