John Ricard Posted June 5, 2014 Share #2 Posted June 5, 2014 I am just wondering, would it make any sense to make the patch a bit larger in the next generation of M cameras?The idea is one could compose a bit easier out of the center of the image. Would not make any sense at all. No matter how big the patch, the only part that matters is the part of coincidence between the two images. If you are shooting at 2.8 or 2 or 1.4, that area of coincidence will be very small because only only that precise area is in focus. In other words no matter how big the patch you are still basically going to be trying to line up details in an eyeball and not an entire head on a standard portrait.

mirekti Posted June 5, 2014 Author Share #3 Posted June 5, 2014 Correct, but I could put that eye more off center. Link to post Share on other sites More sharing options...
250swb Posted June 5, 2014 Share #4 Posted June 5, 2014 80 years of photographers focusing and then composing, when the simple solution was to make the rangefinder patch bigger. I think most people would value the clarity of the viewfinder window as it is rather than have a large blue patch within which most of the image you are seeing double.

Just use the EVF. This auto enlarges the area your focusing on. Link to post Share on other sites More sharing options...
jaapv Posted June 5, 2014 Share #6 Posted June 5, 2014 Correct, but I could put that eye more off center. Which would make the focusing inaccurate. The only way to get exact focus on a rangefinder system is to have your eye in the optical axis. It would also increase the parallax error of the patch. You can even try this one out on the present patch. Focus on a point in the midlle of the focus patch. Now check that point at the edge of the patch. The focus will be ever so slightly off.

genefama Posted June 5, 2014 Share #8 Posted June 5, 2014 Leica makes some of the best lenses in the world but rangefinder focusing makes it so you can't take best advantage of them. In the age of high rez digital, focus and recompose doesn't work for critical sharpness, unless you shift the camera exactly on the focal plane when recomposing.

farnz Posted June 5, 2014 Share #9 Posted June 5, 2014 I am just wondering, would it make any sense to make the patch a bit larger in the next generation of M cameras?The idea is one could compose a bit easier out of the center of the image. If you would find it easier with a larger rangefinder patch then all you need to do is attach a Leica 1.4x magnifier to the eyepiece and as if by magic your rf patch will be larger. In the past I've tried the MegaPearls magnifier and the even cheaper 'Hong Kong' magnifiers and in my opinion the Leica one gives the clearest, cleanest view by a country mile. Be aware though that I stopped using a magnifier (with my 90 APO-Summicron-M asph) because it slightly lowers the contrast in the viewfinder. I had been using my Leica magnifier for a few weeks and took it off briefly to use a 28 mm lens and noticed the additional contrast straight away. Pete.

mirekti Posted June 5, 2014 Author Share #10 Posted June 5, 2014 I do use a magnifier, and that's how I started to wonder about the patch size. I didn't know one should use the center of it for maximum precision, though. Link to post Share on other sites More sharing options...
jgeenen Posted June 6, 2014 Share #11 Posted June 6, 2014 How do You compose in the viewfinder if virtually half of the frame is disturbed by double contures (and you don't see which are the correct ones)?. The size of the focussing patch is a tradeoff: make it too small and it will be Hard to find an edge to focus, make it too large and the viewfinder frame will not show the real target.

mirekti Posted June 6, 2014 Author Share #12 Posted June 6, 2014 I am not saying this is a must. It was just an idea. If the size of the patch would be as when 1.35 magnifier was on, that would be perfect for me. However, I learned the system is the most precise in the centre of the patch so I discarded the idea. Regarding the composition, I try to make the photo in my head first, I don't walk around with camera glued to my face. Link to post Share on other sites More sharing options...
