Telyt2003 Posted August 2, 2011 Share #62  Posted August 2, 2011 Telyt2003 - thanks for the further explanation. I think the next step is to wait until I've got the bits and see what each does - I tend to work better from empirical experience than theory (...)  Welcome! Actually for me it is the same: Normally I just try a set-up mostly empirically. (The 'calculations', hopefully correct, were done just for you, and for the first time since quite some time ). However, knowing the reproduction ratio (easy) is quite useful for an estimate of the exposure time that prolongs considerably with the 'extension', please see below).  Some suggestions, albeit not from an expert: (...) A couple of other practical questions to the experts! 1. For static work (ie tripod / small object documentation) is there an advantage in using a cable release rather than the lever on the Viso III? With a Visoflex3, you do not really need the lever for static tethered work. In red dot-mode, the mirror can be locked up before shooting, and in black dot-mode, the mirror swings up gently while the lever is depressed (only in yellow dot-mode, the mirror springs up suddenly). With a cable release, yellow dot-mode works the same as black dot-mode (mirror does not jump). Would use mirror lock-up and self-timer (Or: Black dot-mode can be combined with a cable release - and self timer ). (...)2. I use a diopter on the M. Can this be swapped onto the viewfinder of the Viso (is it threaded + the same size as the M finder), or do I need to find another solution (or wear glasses while using this set up)? Not directly. The Visoflex3 uses the same diopter correction lenses as the Leicaflex system, if a remember correctly (in a squared mount with fitting rails on the sides. Very hard to get). (...)3. For those using the M9, what's your general practice in terms of metering? Manual and experiment with practice shots + image previews until you get it right, or Aperture Priority? The 'extension factor' for the exposure time, I normally roughly calculated, then checked the results and did the corrections necessary. The formula (according to Leitz' table 12-33) is 'extension factor' = (1 + reproduction ratio) squared. (Example: A reproduction ratio of 0,3 leads to an 'extension factor' of 1,7 or a bit less - bring it down to a round figure, one often reads 1,5) The result is multiplicated with the measured exposure time.  Bellows2003 Link to post Share on other sites More sharing options...
jaapv Posted August 2, 2011 Share #63 Â Posted August 2, 2011 In my experience the A setting works best on the Viso when you set the camera to C. In S mode you get the occasional vastly overexposed shot. Of course the blue dot is covered so the camera has no idea of the expected light level, and if you are a bit fast on the VISO release it seems to react too slowly. On C it seems to remember its last setting (at least that is my theory) Link to post Share on other sites More sharing options...

chris_tribble Posted August 2, 2011 Share #66 Â Posted August 2, 2011 Jaap - thanks. Does the Nikon eye piece drop down into a slot or is it permanently fixed to the body? I've asked Malcolm to go through his boxes of bits to see if he's got any of the original Leica bits - he has a very extensive collection of odds and ends . If this doesn't work I'll see if he can do something along these lines. Link to post Share on other sites More sharing options...
wlaidlaw Posted August 2, 2011 Share #67 Â Posted August 2, 2011 Advertisement (gone after registration) If you are using aperture priority with a Viso on an M8 or 9, you need to be quite slow and deliberate about pressing the Viso arm down or using a cable. If you are trying to use it for say moving objects, I think you need to use manual exposure, as I don't think the TTL exposure meter has enough time to react if you move the release too fast. Maybe C mode works but I have not tried that. Â I was incorrect when I said earlier that you should have the Viso at yellow dot for aperture priority. It should have been black dot. What I did not realise is that if you are using a cable release, black and yellow dot settings both work like black dot i.e. the mirror swings up early in the process to allow light to reach the TTL meter, irrespective of at which setting you have the Viso. Â On yellow dot, the mirror only snaps up as the Viso arm reaches the end of its travel. This can be an advantage for moving shots on manual exposure, as you retain vision until the last fraction of the movement of the Viso arm. I also have to set up the arm slightly differently to get this to work, removing my softie, to allow the Viso arm to travel further, before it triggers the M8 shutter. I know folks do use M's and Viso for things like motor racing shots and I have once but it is far from an ideal combo. Â Wilson Link to post Share on other sites More sharing options...

For fixed macro work I tend to use the straight funnel viewer which does have a built-in diopter correction. Link to post Share on other sites More sharing options...
chris_tribble Posted August 2, 2011 Share #69 Â Posted August 2, 2011 Wilson - no plans to use it with long glass! Static small objects and maybe some things outdoors - but always on a tripod. The 5D2 still has it's uses (+ fast 200/300 primes) Jaap - interesting. Do you reckon the vertical viewer is worth getting? Available for the Viso III?

Brian Bower Posted August 2, 2011 Share #70 Â Posted August 2, 2011 Hello Chris, Â Just been reading this long thread on the forum. It can get get very complicated with all the adapters etc. Like you I prefer to have the bits in front of me to see exactly what they do! Â I see you list Cheshire as one of your locations. I'm there too and if you think it could be helpful to you PM me and we can arrange for you to come over and try the possibilities of different bits of Visoflex gear. I've got a 2 and a 3 with a vertical magnifier and both horizontal types, a bellows unit, nearly all the adapter rings and some extension tubes as well as various lenses. Â The Viso system is is definitely the big boys Meccano set! Link to post Share on other sites More sharing options...

Yes- they crop up quite regularly, identical for Viso II and III. I would say it would be ideal for the intended use. Only drawback: the image is shown mirrored.

wlaidlaw Posted August 3, 2011 Share #72 Â Posted August 3, 2011 These vertical (chimney) viewers are quite expensive.

Only drawback: the image is shown mirrored.  They´re beastly to use for vertical shots too... But they give higher magnification, AND have dioptre adjustment built right in.  Actually, for pure macro using a tripod, an old Visoflex I with 45 deg prism is hard to beat, and they´re usually dirt cheap.

jaapv Posted August 3, 2011 Share #76 Â Posted August 3, 2011 Yes - you can use the II with the vertical finder - or the pentaprism of the III. But there is a wide variety of release arms and not all will suit the shutter release. Link to post Share on other sites More sharing options...
thighslapper Posted August 3, 2011 Share #77 Â Posted August 3, 2011 The usual finder supplied with the Viso II sits too low and there is not enough clearance on the top of the M8 or M9. As Jaap says the alternative slide on finders allow it to be used .... but it seems sensible to stick to Viso III. Â If you are not fussed about cosmetics you can pick these up cheaply..... in fact I now have a pile that I have pick and mixed from to get a mint Viso III and Viso IIa ...... buying bits seperately was as wilson says expensive.

Is it OK to use them if you're only working with the vertical finder? If yes, then I might be able to trace one...  Chris, at risk of being a bit repetitive, I am still advertising the many (potential) advantages of the older Visoflex2 mirror housing (if combined with the Visoflex3's pentaprism or the 'chimney' finder) when used on the M8/9.  The vast majority of the Visoflex images that I have shown so far, is made with this "Visoflex2/3" combination (on the M8).  The disadvantages of the Visoflex2 housing, as compared to the Visoflex3, are quite irrelevant for me, and for macro work even more so. Both can be combined with the 'chimney finder', as already said.  All Visoflex2 housings that I have checked so far (and that were made for the M, not for a screw mount Leica), fitted the M8. The M8's shutter button may be slightly depressed permanently with some Visoflex2. Not a real problem, because the release arm of the Visoflex2 can be folded forwards (away from the camera) and then still can release the mirror - very practical in many situations! (macro and tripod work) Some Visoflex2 housings sat slightly oblique on the M8 (but then would probably also have done so on any other M camera?). I understand that the Visoflex2's bayonet can be oriented (Didn't check, if this is really the case).  Please compare here: http://www.l-camera-forum.com/leica-forum/1735000-post15.html or in the Visoflex interest group: http://www.l-camera-forum.com/leica-forum/groups/visoflex-d12-your+visoflex+....html or here (in German): http://www.l-camera-forum.com/leica-forum/1765563-post32.html  Best regards, Visoflex2(00)3 Link to post Share on other sites More sharing options...
wlaidlaw Posted August 3, 2011 Share #79  Posted August 3, 2011 I sold a Viso II last year, that came with the large case of Viso lenses, assorted bits and adapters I bought. From memory, I got around £65 for it. Even with the viewer off, the mirror arm of mine did not mate very well with either an M8 or 9.  Just looking at some other Viso stuff I have that I am never going to use, I have a 14127 adapter to mount Viso lenses on an R body. It looks as if it has barely been used. Any interest to anyone?  Wilson Link to post Share on other sites More sharing options...
