Advertisement Posted November 25, 2018 Posted November 25, 2018 Hi jrp, Take a look here 50mm Summilux vs Summicron. I'm sure you'll find what you were looking for!
Peter Kilmister Posted November 25, 2018 Share #62 Posted November 25, 2018 I would also add 'weight' and 'blocking the viewfinder' to any list. Some lenses are so huge that they become a Herculean labour to being carried any distance and, by virtue of their size, prevent an unimpeded view unless an EVF is used. Those might be acceptable, and surmountable, problems in a studio. On a long walk they become a real irritation. The 50mm APO Summicron is light and compact, doesn't block the viewfinder, is very sharp from corner to corner, gives excellent bokeh. I think that a couple of stops of speed can be easily compensated by increasing ISO from 200 to 600 with no loss of image quality. Precisely what 'near limit' means is a mystery to me. In summary, use whatever lens with which you feel comfortable and takes great pictures. For some it will be a Sumo wrestler like the Noctilux 0.95. For others it will be a Voigtlander. For me, an elderly country bumpkin who likes to walk, it is the 50mm APO Summicron. Quote Link to post Share on other sites More sharing options...

a.noctilux Posted November 26, 2018 Share #65 Posted November 26, 2018 Satisfaction has no price 😵. Illusion can lead to satisfaction or whatever it's called if one can buy the objects of desire. Quote Link to post Share on other sites More sharing options...
Exodies Posted November 26, 2018 Share #66 Posted November 26, 2018 There is an illusion associated with ageing eyes. In low light one can’t read a map or make anything out in a picture but one can read text. It may be partly the higher contrast of text but there is also the massive quantity of brain dedicated to the task of reading. This effect can be quantified and can also be classed as an illusion. 1 Quote Link to post Share on other sites More sharing options...
Pyrogallol Posted November 26, 2018 Share #67 Posted November 26, 2018 (edited) Advertisement (gone after registration) For those of us who enjoy trying to get the best out of a variety of uncoated pre-war lenses “sharpness” is something we appreciate when we can achieve it. Lighting, hand steadiness, aperture, haze - inside or outside the lens, all add up to the sharpness we can end up with in prints, and I mean prints, that can be studied at leisure and under different lighting and on different papers, just viewing pictures on a screen for a brief moment does not really amount to much. For me, any modern lens seems to be very sharp and contrasty when I use one, like my 50mm v4 Summicron or 35mm v3.

anthonym3 Posted December 8, 2020 Share #68 Posted December 8, 2020 Think about this. Is it at all believable that KEN ROCKWELL who is always begging for "donations" has the wherewithal to afford the hundreds if not thousands of photographic items that he reviews or is able to borrow them? I believe that he gleans information from reviews by others and tailors them for his reviews. His review of the LEICA 3f in particular indicates that he has probably never actually used one. His "twice as many knobs and settings" etc. claim puts the lie to his alleged review. Quote Link to post Share on other sites More sharing options...
84bravo Posted December 10, 2020 Share #69 Posted December 10, 2020 If I were limited to only one lens, I could do almost everything with just the 50mm Summilux asph. It's incredibly sharp across the range and I like the look it has when shot wide open. It's a very snappy modern lens and very versatile. I have the 50 Summilux asph and the 50 Summicron (IV). I bought the Summicron used in the early 90's. It was cheap and cosmetically not pretty, but a stellar performer. I used it hard as a working photojournalist for years. I felt convinced that it would be the only 50 I would ever need....until I purchased the Summilux asph. The advantage of the Summilux is the 1.4 aperture and the look that it makes that you just can't get with an f2 lens. If that look is not important to your style of photography then save your money and get a Summicron. BTW, I have an embarrassing number of 50mm lenses as I find it the most versatile lens for my work. One can easily go down a rabbit hole of different looks with the variety of Leica 50mm offerings. The old Summilux V1 and Summarit I find very difficult to use, but can produce a classic look that modern lenses can't when used properly. The modern designs are much more forgiving. The Summitar is one of my favorites of the classic designs. 3 Quote Link to post Share on other sites More sharing options...
