I love how much more "natural" fish-eye distortion is than a rectilinear ultra-wide: Jam your nose into the image (or my big print and you don't even notice it. It was also an attempt to produce an interesting composition using a full-frame (37mm) fish-eye lens of an angular, architectural subject.

The skylight at the top left is in full "sunny 16" bright sunlight, whereas the area underneath the tables in the extremely dark library were almost pitch black to the naked eyed (this was a very dark library, and the image is a 4-minute exposure). On a technical note, the dynamic range of even Pan F (developed in diluted D76-equivalent developer, 1+1) blows my mind. The interior is of the very old, and supposedly haunted, Africana library.

You can directly download the RB67 pdf manual in English from mamiya Netherlands here. Indeed on the 50mm, it also adjusts the floating element. On most lenses, this ring has no other function, it is just a calculator and not linked to the optics. Third: all lenses have a front ring with an indication of distance and depth of field. All the curved lines end up at the same point at infinity, roughly next to the figure "360mm". The curved lines have colors so that you can more easily associate them to their respective focal length. It also roughly indicates your present focus distance: junction of the curved line corresponding to the focal length with the vertical distance scale. Please extend the belows to the maximum to understand the following explanation: that scale indicates, for each focal length, at which distance you need to open 1 more stop to compensate (grey zone with points) or 2 stops to compensate (hashed zone). Second: you see 1m in front of 50mm at infinity, but it has nothing to do with the floating elements. If it is focussed to 2m, put the floating element to 2m, etc. I had to get the RB67 out to understand what you meant, and you are very much confused, I am afraid.įirst: if the lens is focussed to infinity, put the floating element to infinity. Do I need to set the floating element to the hyperfocal distance or is it not necessary if always focussed at infinity and using small apertures? I suspect the closest that part of my foreground subject matter would get to the film plane would be about 2 meters. I was wondering if anyone could give me any tips with the floating element for this style of work? My lens of choice is the 50mm so shooting very wide. It seems infinity focus is attained by not extending the bellows at all which is rather convenient. Most of the images I'm likely to produce with this camera will be landscape images at infinity, often long exposures. Basically I'm still a little confused as to the floating elements, having not used them before. I actually had a technical question regarding the RB system, so I thought this would be an ideal place to ask rather than to start a new thread. Just received the cam a week ago and loving it, got some decent results already. As you've probably guessed I'm new here, I found this site via google results for this specific thread when I was researching my RB67 purchase. and I eventually began searching for greener pastures.Hi guys, some great images in here. Missing focus on roll after roll began to drive me crazy. I also found critical focusing extremely hard on the 645J due to the size and limited brightness of the viewfinder.
I attempted to compensate for this by buying a left-hand grip, but I felt that it only exacerbated the issue. The boxy design allowed no real space for a proper grip, resulting in a lackluster shooting experience. The Mamiya M645J ( find on eBay) became my go-to travel camera, bridging the gap between the portability of a 35mm camera and the quality of medium format.Īll good things come to an end, however, and a few months into heavy use with the 645J, some issues began to become apparent.įirstly, I found the camera way too awkward to operate for any extended period of time. The model I owned also came with a metered prism finder which eliminated the need for a handheld light meter and allowed for a more streamlined shooting process.

After my first roll was developed, I knew from that point on I could never return to only shooting 35mm.įor a medium format camera, the Mamiya 645 was super portable and very lightweight I could throw it on my shoulder or into a backpack and forget it was even there. The quality jump from my very first film camera, the Canon AE-1 Program, to the Mamiya 645 was, to be frank, insane.
