cliveruss Posted February 8, 2015 Author Share #21 Posted February 8, 2015 Advertisement (gone after registration) selected f16 on the APO 50. Other stuff: 1/250 sec. medium red filter, ISO 320/M Monchrom and focussing on the legs of the horse in the centre We are buried under feet of snow, -20C and windy, so it is nice to see your Summer photo. Thank you for including it in this discussion. Your image looks very clear on my screen. If you were to make a 20" wide print, does the detail on the area of focus (horses) become fuzzy? At the enlarged size does the whole image look fuzzy? I often need to focus at about 10' but would like the dof to include about 5' to ∞. The red filter does not make the sky as dark as I expected. Perhaps the M sensor is quite sensitive to red light. Pan film would have rendered the sky darker. monadnockregion - Page 1 Link to post Share on other sites More sharing options...
Advertisement Posted February 8, 2015 Posted February 8, 2015 Hi cliveruss, Take a look here ƒ/16 with a 50mm Summicron or Elmar. I'm sure you'll find what you were looking for!
platypus Posted February 8, 2015 Share #22 Posted February 8, 2015 cliveruss, Your winter does sound extremely severe, you have my sympathy! As regards my shot of horses on the beach; I printed it yesterday to A3+ (19") on Canson Infinity Photographique (which is not as textured as some) and was pleased to see that everything is still sharp, from the foreground grass up to and including the far headland. A3+ is as large as I am able to go with my Epson R3000 printer, but I see no reason why this image would not go larger without loss. As to the sky....that is not the result of the red filter, I must admit to having darkened it a tad in pp, I have a weakness for dramatic b&w skies.

cliveruss Posted February 9, 2015 Author Share #23 Posted February 9, 2015 everything is still sharp If you can make an A3 print which looks good from an ƒ/16 exposure, I am surprised and pleased, except that I will have to now get one! At the very least I will have to make the effort to test one against an Elmar. I bet using the Apo Summicron at wide apertures is a treat. Using an M camera is so much easier than dragging a view camera up a mountain. View cameras are a bad mix with snow and wind. Link to post Share on other sites More sharing options...

So true about the size of the camera relative to the size of the mountain! Regarding my pleasing print result; you should note that the image was taken with the APO 50 attached to an M Monochrom...... a combination of camera and lens which makes all the difference to the final print result, or so I have found. And yes...the APO 50 (+MM) is a joy through all apertures, they are far from a one-trick pony. Link to post Share on other sites More sharing options...
Exodies Posted February 9, 2015 Share #25 Posted February 9, 2015 Thank you Exodies. That is exactly what I want to see with the Apo-Summicron 50mm. The image looks soft to me, but that is on my computer screen. If you were making a 50cm wide print from this image (the whole image), does the diffraction blur the fine details even in the focused part of the image? Does the snow look like chalk? If you are able to describe the image quality as you see it on your screen, I would find that helpful, or a print would be even better. Do you think the image quality is any better than the image from an older Summicron-M 50mm, both at f/16 of course? We know your new lens is better at f/2. I have sent you a link to the DNG in Dropbox, see your private messages. The snow at the focus point glitters; it's not chalkey. Most of the image is soft because I focused on the front of the snowbank which stretches away almost perpendicularly to the sensor plane. The distance from the focus point to the oval window on the old tower is 98m, to the office building at the back is 471m. Here is a plan of the shot (I'm a diagnostician, can't help obsessively gathering evidence): Welcome, dear visitor!

cliveruss Posted February 9, 2015 Author Share #26 Posted February 9, 2015 Thank you very much for the DNG file, Exodies. It is very informative. A full sized image (about 20" wide) shows that the detail is still excellent in the focused area. I did not expect it to be this good. The diffraction does not harm the detail much at this size. The next surprise is that the out of focus area does not have any "color" which means that the chromatic aberration does not damage the image. Okay, that's why they call it "Apo". My Summicron-M shows obvious "color" in the out of focus areas, green behind, magenta in front of the focus, even at ƒ/8. My 1959 Summicron is even worse. I am using an M9. Platypus tells us that her A3 print with the Apo at ƒ/16 and Monochrom is sharp. The Apo-Summicron is clearly a better lens than my Summicron-M, even at ƒ/16. I don't have any images from an Elmar-M, but I suspect it won't be any better than a Summicron-M. I have attached a color image from my Summicron-M to show why dof matters. Even movements on a view camera would not help this image much. ƒ/16 or ƒ/22 on a small camera is advantageous here ... as is a tripod. Link to post Share on other sites More sharing options...
platypus Posted February 9, 2015 Share #27 Posted February 9, 2015 Advertisement (gone after registration) Platypus tells us that her A3 print with the Apo at ƒ/16 and Monochrom is sharp. I don't want to appear pedantic but....to be accurate, the print size is A3+....13"x19" or (in metric, which we use here) 329mm x 483mm. I have utilised the full sheet. On close inspection I think the image would quite happily go to A2. Link to post Share on other sites More sharing options...
cliveruss Posted February 10, 2015 Author Share #28 Posted February 10, 2015 A3+....13"x19" Yes, I got that. It is about 20" wide. That is a bit bigger than I usually print, but close enough to show that the lens is really good. It may also mean that I will just have to get an Apo! It seems like my image did not show in my previous reply. I definitely uploaded it, but I must have missed a step in the process of having it show.

cliveruss Posted February 11, 2015 Author Share #30 Posted February 11, 2015 1979 Summicron at ƒ/5.6 showing "color" in the background trees. In a 13x19 inch print it is very obvious.
