Keith (M) Posted February 4, 2011 Share #1 Posted February 4, 2011 Advertisement (gone after registration) Newbie Alert! I have just put my Summarit 75mm on my newly-acquired M2 and see that it brings up the 50mm frame in the viewfinder. Anyone any idea or experience on how accurately one can guess what will be in the frame? Does it just mean alternating between the 50 and 90mm brightlines whilst judging if what one wants to photography falls half-way between? Link to post Share on other sites More sharing options...

bill Posted February 4, 2011 Share #2 Posted February 4, 2011 'cos it's the same cam. In later cameras the 50 and 75 framelines come up together, remember. I can't say I have ever used my 75 (it's a CV) on my M2, but I have used it on my II. I just visualise slightly tighter; it seems to work. Give it a try.

Does it just mean alternating between the 50 and 90 mm brightlines whilst judging if what one wants to photography falls half-way between? Not half-way but three-quarter-way. That is, the 75 mm framelines—if the M2 had them—are much closer to the 90 mm framelines than to those for 50 mm. Three quarters of the way from the 50 mm frameline to the 90 mm frameline exactly.

Xmas Posted February 4, 2011 Share #4 Posted February 4, 2011 Hi Wait until you have no film in the M2, remove baseplate and back stick grease proof paper(from kitchen) across film gate with pressure sensitive tape rest base of canera on a table, focus on subject about 15 feet. Compare 5cm frame with 75mm picture on grease proof paper. Use 5cm frame for shooting but dont put critical things too near edge. Noel Link to post Share on other sites More sharing options...
adan Posted February 4, 2011 Share #5 Posted February 4, 2011 Since 75 = 50 x 1.5, and the ratio of the 35mm frame is also 1:1.5, the horizontal framing of the 75 is equal to the height of the 50 "box". For estimation purposes. The 75 frame would be not quite halfway between the 50 frame and the edges of the RF patch (closer to the 50 lines). Which are both visible at once, unlike the 90 lines. For longer distances (> 10 feet), Bill's "just visualise slightly tighter" than the 50 lines is not bad (Leica frames are conservative, so you always get more than the lines in the final image). For really close work, halfway between 50 and the RF patch will be "safe" (you'll also get a bit more in the final image, but never crop off heads by mistake ) Link to post Share on other sites More sharing options...

Hi No I'm an engineer though. If you do what I suggest and investigate other distances you will have more confidence, in the other posters.

Your suggestion is certainly worth trying out when i have finished the film in there at the moment. As to confidence in the other posters, my short time on the forum has given me an appreciation of the wealth of knowledge a lot of forum members have and their willingness to share it.

earleygallery Posted February 5, 2011 Share #11 Posted February 5, 2011 Another option, sell the 75 and buy a 90! Or if you have an iphone you can download a 'viewfinder' app. Link to post Share on other sites More sharing options...
ho_co Posted February 6, 2011 Share #12 Posted February 6, 2011 Keith-- Remember, instead of trying to interpolate the 75's field of view, you might also think about buying a Voigtlander Viewfinder with Brightlines for 75mm Lens - Silver DA414A.

wda Posted February 7, 2011 Share #13 Posted February 7, 2011 Keith, when I occasionally used a 135mm lens on my M8, I quickly found that I could estimate the reduction of field when using the 90 frame as a guide. Admittedly you don't have instant feedback with film, but it is worth trying interpolation. There is some latitude in framing, usually. Link to post Share on other sites More sharing options...
tobey bilek Posted February 7, 2011 Share #14 Posted February 7, 2011 75 mm Cosina Voitlander bright line finder. I prefer this even on cameras that do have 75 mm lines. You can not guess. Link to post Share on other sites More sharing options...

Thanks for the suggestion . However at a new price of over $140 (plus shipping, import duty, VAT), I think I'll try interpolation for a while! (The viewfinder does not appear to be marketed in the UK). PS - just seen one on EBay with a current bid of $12.50 (4 days to go). My first rolls of film should be back before bidding ends, so I'll be able to see how my attempts with interpolation came out and decide whether to bid or not.

tobey bilek Posted February 8, 2011 Share #16 Posted February 8, 2011 I am sure there is a CV dealer in UK or Stephan Gandy will ship one `cross the pond. Photo Village in New York also stocks them. You can also calibrate an Imarect VF. Crappy viewing, but infinately variable in the design range, ie analog not digital. Link to post Share on other sites More sharing options...

Washington Posted February 13, 2011 Share #19 Posted February 13, 2011 I too use the Voigtlander bright line finder purchased from Stephen Gandy and it's great! Very well made. Link to post Share on other sites More sharing options...
ferider Posted February 19, 2011 Share #20 Posted February 19, 2011 Given 50mm lines, you can estimate the 75 framelines like this: Link to post Share on other sites More sharing options...
