Specially due to the hard shooting conditions. How was the lens a different apertures? I forgive you 😂 By the way, I like this wide open month (f/2 for me)... Hi Dennis. Yes; the first - poor thing - was in effect shooting dark shadows with the lens pointing directly at what little light there was so I thought it would be a good test of the lens' ability to deal with veiling flare. 'Not its Strongest Suit' as it turns out! I'll see if I can salvage something better from either that frame or one of its neighbours - I only had a quick edit last night after I returned home so might easily have overlooked a more capable file. As far as using different exposures is concerned I limited the aperture use to either f1.5, f2 or f2.8. As one might expect sharpness tightens up quite quickly on stopping-down but, in doing so, IMO loses a bit of the 'wonder' of the image. As you say; the wide-open shots are very reminiscent of 'Old Glass' but as the lens was designed over eighty years ago I suppose we should hardly be surprised! Here is the companion frame to the one in post #139 with this one being shot at f2.8; Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! If you click-to-enlarge both images it should be evident that the detailing of the aerials on the mast is much clearer. Obviously these have been reduced from 51mb down to sub-2mb and at lower quality into the bargain but hopefully the difference can be seen. Anyhow; just some snap-shot experiments under 'interesting' conditions. The sun is shining in a cloudless sky at the moment and the snow has not yet vanished so I will try to make time for a walk to grab some images further down the aperture road. I might have to jury-rig a lenshood onto the Summarit - but if so I'll also be interested in trying-out both 'with' and 'without' versions to discover how much difference a hood makes; the Summarit takes a XOONS hood which is in 'Collector's Territory'. I doubt I will have time to get back to the same place but we'll see... Philip.

In any case if I want crispness I can use my Summicron but if I want 'A Foggy Day in London Town' I can use this wide-open!............ I did manage to shoot off a few frames earlier on today (whilst doing the milk-run) and one notable result is that when using the Yellow Filter - which I'm using all the time to protect the very soft coatings on the front-element more than for any other reason - I will, in future, need to compensate for focus-shift by turning the indicated-focus half-way towards the infra-red mark on the lens' d-o-f scale. If I want sharp images. Which I might not..... All the mid-range (f4 - f11) apertures produced 100% perfectly good images after which point diffraction gradually becomes a major issue. Still Learning! Best wishes for the continuation of the f2 month! Philip. Edited February 10, 2021 by pippy 2 Link to post Share on other sites More sharing options...

And because the 50 it's my longest lens on M, I'm interesting to get another not expensive 50 to use it wide open only, such as TT 50/1.4 or the brand new CV 50/1.5II.. Still seeing and asking as always between threads. I'm not sure yet, but after three years, I guess my perfect FL trinity could be 21 + 35 + 50. For my way to shoot and to see (and interpret) the world, it totally makes sense. 11 minutes ago, pippy said: Best wishes for the continuation of the f2 month!

pippy Posted February 12, 2021 Share #148  Posted February 12, 2021 (edited) Well, still learning and having fun with the old Summarit. Last night's wander took me down to the short parade of shops which is the tail-end of our 'High Street'. Tonight I removed the yellow filter just out of curiosity. Snap was taken on M Monochrom set to ISO 320. Exposure was 1/25th @ f1.5. I'm still surprised at how well the lens copes, in terms of flare-resistance, with specular highlights within picture area. Also there appears to be less 'Craziness' going on here but that might just be because there is less 'well-defined' stuff to go crazy with! Must do more experiments. As usual double / triple click to get slightly sharper, larger view; Welcome, dear visitor!

With those settings I find 1/25th is pretty straightforward when using a 50mm lens. With a good stance I can usually get down to 1/8th but below that can be very hit-and-miss. Usually miss!

Just going back to this point for a moment; This is the strange thing. I had heard so much about the Summarit being a low-contrast design and so prone to flare that it was ridiculous to even think about using the lens without a seriously good Uv filter and an even better hood. But the images I've been posting here have had practically no Post-Prod work done whatsoever. All images are shot as DNG so straight-conversion apart my main input is primarily about correcting horizons / verticals as and when neccessary. I have come to the conclusion (perhaps erroneously) that most reviews have been carried-out with sub-par examples and that the way mine behaves is more akin to what they would have been like when new.

Thanks, Dennis. Yes; I think it's fair to say that I'm both surprised and also very encouraged by the first week's worth of experiments and am delighted with the potential of what it can provide. So far I'm trying to use it (almost!) exclusively wide-open on the M Monochrom for the 'One Lens / One Camera / One Aperture' idea. Going forward I will be very interested to see how it behaves if used as a 'regular' 50mm but there are obvious reasons why this is impossible for the time being. The images I have snapped, so far, further down the aperture scale suggests it might be pretty useful as an all-rounder - although (probably) not nearly as 'good' as the Summicron - but, in any case, my gut feeling is that it will only come into its own when rendering at f1.5. First day of shooting apart (the Red Berries on Tree snap) I've not really taken it out with the 'Colour Body' yet so that is another treat to be savoured as and when the time comes. And I am looking forward to it! Philip. Edited February 13, 2021 by pippy 1 Link to post Share on other sites More sharing options...

Snap is actually a central crop from a horizontally-shot pic but I couldn't get any closer to the subject matter (fence / pallisade in the way) so had to crop-in later. Although it looks like nothing is sharp here there is the TINIEST hair of grass on the main 'head' of the plant which, even when viewed at 200%, is razor sharp! If you double / triple click and look at the area lower-right-hand-side where the seed-head is seen against the dark patch... Hey; I'm not going to say "At Minimum Focus This Lens Back-Focusses 2cm!" or any such crap. I could hardly focus the camera as it was both windy and rather dark at the time I took the snap. I don't mind there being so little 'sharp'. In fact I love the fact that there is so little sharp! It seems to be a defining feature of the character of this lens when used wide-open and I love the look. I did also shoot some images at f4 / f5.6 and, down there, the Summarit is as sharp as anything I'd ever need. But as you, yourself, noted in post #148 it's only at f1.5 where this lens comes shows its real character. True Story! When I was a student there was a watercolour by J.M.W. Turner ("Seascape; Folkestone" I believe) which sold at auction for around the $10m mark which, 35 years ago, was quite a bit of loose-change. I remember reading an article by a journalist at the time who, in conversation with the London cabbie in whose taxi he was travelling, mentioned he had just been covering the sale of the painting for his column in the paper. The cabbie was shown the catalogue's picture of the work and said "Funny how these Paintings which sell for millions always seem to be a bit out of focus"...
