![]() This is the top of the sheet for the interchangeable examples (there was another page for fixed lenses) and there were 300 rows, indicating 300 example lenses, on this page alone. Among the things we did were measuring the physical length of the barrel and also checking the focal length group for the ones which we actually had in our collections. Von Hasbroeck had listed 25 variants, but, of course, we found many more, particularly after consulting the book by von Einem on Model I As with Elmar. Some years ago, fellow Forum member Jerzy and I started a joint (should really be giant) spreadsheet on the humble 50mm/5cm Elmar to determine how many variants actually existed. I assured her this is very unlikely to be the case. Reaching for the kitchen scales just now I was surprised to be accused by Mrs C as being "the only person in the world who keeps a spreadsheet of the weights of their lenses" Incidentally - and as has been widely discussed elsewhere over the years - the f2.5 was, according to Erwin Puts, really an f2.4. For the sort of stuff I use a 90 for this 10cm difference has never once even remotely been an issue. Mine happens to be the earlier "f2.5" verision which has a min-focus of 1m instead of the 0.9m of the later f2.4. The Summicron is also slightly longer than the others (82mm).Īt wide apertures the rendering of the Summarit - as might be expected - is definitely more 'modern' than any of the others but once stopped-down to f5.6 there's really no appreciable difference in 'real-world' shooting (IMO). ![]() The T-E weighs 115g less than the Summarit (225g / 340g) but the latter is still 145g lighter than the Black-Chrome finish Summicron (485g). It has that half-stop speed advantage over the T-E yet is almost exactly the same length (69mm / 70mm) when these lenses are both sporting their hoods (reversed for carrying) and caps. The Summarit is sharper at wider apertures than either of the Summicrons or the '74-'90 f2.8 Tele-Elmarit 'Thin' and handles beautifully. Time for a few more weights and measures. I'm still keeping my eye out for the 'perfect 90' for that.įirst-off I'm happy relieved to read that you like the Summicron otherwise I'd suffer from guilt-pangs for the rest of time.Īlways bearing in mind that there is no 'perfect' lens I've said it before but if I could only keep one of my 90mm M lenses it would be the Summarit. I'm still keeping my eye out for the 'perfect 90' for that □ ![]() Really beautiful lens.ĭefinitely not for travel though is it. I bought it on impulse (and largely on your recommendation) when I came across one in an in-person store rather than online. It is, however, a beautiful performer and with looks to match. To put this 'mass' into perspective my usual trio of 'carry-about' lenses - a 28 Elmarit ASPH v1 a v2 ('74) 35mm Summilux and a 50mm Summicron v4 - come in at a positively anorexic 561g for all three combined(!) their respective weights being 178g, 186g and 197g.Īdmittedly the 90 S-C has a bult-in lenshood whereas the others were 'un-hooded' for the purpose of the experiment but even so it is definitely on the 'Big Boned' side. It weighs-in at 686g so pretty much exactly the same as your own example. These scales are only accurate to the nearest gram so no decimal points I'm sorry to say. Just for interest's sake, Graham, I've just re-weighed my 90 S-C Summicron v3 on a set of digi-scales.
