Abhinava Goswami Posted January 5, 2013 Share #1 Posted January 5, 2013 Advertisement (gone after registration) Here my question is that,that somebody told me that 50 has more resolution that 35 so I am confused. Abhinava Goswami Link to post Share on other sites More sharing options...
Advertisement Posted January 5, 2013 Posted January 5, 2013 Hi Abhinava Goswami, Take a look here 35f/2.5 vs 50f/2.5 Summarit. I'm sure you'll find what you were looking for!
01af Posted January 5, 2013 Share #2 Posted January 5, 2013 That's nonsense. Both lenses are fine; simply choose the one that matches your requirements/preferred subjects/way of seeing. Link to post Share on other sites More sharing options...
jaapv Posted January 6, 2013 Share #3 Posted January 6, 2013 There is not one lens in the current Leica lens line that has "insufficient" resolution. Apart from being nonsense, it is a non-issue. Link to post Share on other sites More sharing options...
kokoshawnuff Posted January 6, 2013 Share #4 Posted January 6, 2013 As was said above, in addition to the fact that those who know about such things and have done testing (ie Puts, Reid and others) say that the 35 "out-performs" the 50...ultimately they're two fantastic lenses (I've owned both) so pick the focal length you prefer Link to post Share on other sites More sharing options...
lct Posted January 6, 2013 Share #5 Posted January 6, 2013 I have no experience with it but the 50/2.5 outperforms the 35/2.5 on the M9 according to J.M. Sepulchre (http://tinyurl.com/6bjmngt): less vignetting, less distortion, less CA and more sharpness on edges and corners. Link to post Share on other sites More sharing options...
Tonki-M Posted January 6, 2013 Share #6 Posted January 6, 2013 no sensor in any foreseeable future would out-resolve the resolution of Leica lens..even a summarit...a non-issue indeed, as Jaapv said. Link to post Share on other sites More sharing options...
MarkP Posted January 6, 2013 Share #7 Posted January 6, 2013 Advertisement (gone after registration) Why the question as you are comparing different focal lengths? If you are considering one of these two lenses base the decision on the FL you want, not minute differences in performance. Both are excellent lenses.

Carduelis Posted January 6, 2013 Share #8 Posted January 6, 2013 I have no experience with it but the 50/2.5 outperforms the 35/2.5 on the M9 according to J.M. Sepulchre (http://tinyurl.com/6bjmngt): less vignetting, less distortion, less CA and more sharpness on edges and corners. I think this is where the confusion lies because the 35 mm Summarit seems to be the best out of the bunch according to Erwin Puts and the 50 mm Summarit seems to be the weaker lens out of the bunch that is often compared with the 50 mm Summicron. From what I can understand of MTF curves, there does not appear to be any resolution issues with the 50 mm Summarit, particularly at f5.6. From what I can understand of MTF curves, the 35 mm Leica lenses do not quite seem to follow the resolution performance of the 24mm Elmar and 50 mm lenses particulary towards the edges.

lct Posted January 6, 2013 Share #9 Posted January 6, 2013 Edges are very good at f/2.8 and on with both 35/1.4 asph and 35/2 asph, less so with the 35/2.5. As for the 24/3.8, it is a great lens indeed but it is softer on edges and corners than the 24/2.8 asph below f/8. Just Sepulchre speaking as i have not the latter lens and i don't use the other ones on full frame cams so far. Link to post Share on other sites More sharing options...

Carduelis Posted January 6, 2013 Share #11 Posted January 6, 2013 If you read Erwin Puts completely you will learn that it is incorrect to compare MTF curves across different focal lengths. Fair comment. However I was making my observations based on the MTF curves either side of 35mm lenses for 24mm and 50mm lenses. Intuitively I was expecting the 35mm lens MTF profiles to be flatter and not to fall off as much at the edges. I would welcome a thread in this Leica M lens section of a couple of appropriate illustrations of lens MTF curves for discussion by forum members so I could further my knowledge about them.

swamiji Posted January 7, 2013 Share #12 Posted January 7, 2013 There is not one lens in the current Leica lens line that has "insufficient" resolution. Apart from being nonsense, it is a non-issue. Ok, Gentlemen, here is a variation of Swamiji's question. The difference between optical resolution and digital resolution. One of the selling points that I remember reading about with the 50mm APO-Summicron ASPH, is it's higher resolution with both the Monochrom and the M type 240. It's been my experience that no matter what lens I put on my Monochrom it produces a high resolution image (given the nature of the lens of course). I have not seen that much of a difference, in comparing one lens to another, on the Monochrom vs. the M9. Reading the early promo material, it kind of implied that if you own a Monochrom, you need the 50mm APO-Summicron ASPH, or you are wasting some resolution. Which from my experience so far, is silly... But if Swamiji had picked a comparison of the 50mm Summarit and the 50mm APO-Summicron ASPH, would your answer been any different?

jaapv Posted January 7, 2013 Share #13 Posted January 7, 2013 The point in case is that it is not either/or. The lens and the sensor work together to create the image. Even if you put a lower resolution lens on a higher resolving sensor there will always be an improvement, and the other way around. I would take the Monochrom out of the equation, as we are talking about better acuity there, not higher resolution. It is the same 18 Mp the M9 is. Additionally, it eliminates chromatic aberrations, especially when one uses color filters. One of the reasons , if not the reason, that it does so well with older lenses.

swamiji Posted January 7, 2013 Share #14 Posted January 7, 2013 Well, the word Leica used was Resolution. But either way, does that imply you would not see the extent of improvement from the 50mm APO-Summicron on the M9 as you would on a Monochrom (or reportedly the M 240)? Thats what Leica PR wanted us to believe. Does absence of color, since it eliminates chromatic aberrations, also remove the need for an APO lens?

01af Posted January 7, 2013 Share #15 Posted January 7, 2013 ... if you own a Monochrom, you need the Apo-Summicron-M 50 mm Asph, or you are wasting some resolution. Which from my experience so far, is silly ... That's what I keep saying, over and over. There is no such thing as a lens that outresolves a sensor, and neither there is a sensor that outresolves a lens. Improve the sensor, and it will improve the image quality, regardless of the lens. Improve the lens, and it will improve the image quality, regardless of the sensor. It's so simple, still people refuse to understand ... Link to post Share on other sites More sharing options...

Thats what Leica PR wanted us to believe. Does absence of color, since it eliminates chromatic aberrations, also remove the need for an APO lens? Basically yes, but you may create focus shift if you use a red filter, for instance. Having said that, it is not just the absence of color. If you use full-spectrum light the chromatic aberrations will produce unsharpness (which is as such a lot better than color fringes), but if you use monochromatic light like a filter produces, those aberrations will become largely irrelevant. The Apo-Summicron is not just about lack of chromatic aberrations, btw, it has other qualities that are just as important. Link to post Share on other sites More sharing options...

It's so simple, still people refuse to understand ... It makes sense to me, and it's also my experience! But when Leica PR implies differently, confusion can occur.

jaapv Posted January 7, 2013 Share #19 Posted January 7, 2013 I suppose the reason is that marketing-speak needs to scale down to the lowest common denominator. Start talking about frequency response and microcontrast and you lose 80% of your audience...Not to mention esoterica like Airy disks, diffraction limitation etc, and the percentage mounts to 95%. Precisely the opposite of the effect you want when pushing lenses. They cannot reach for their wallet with glazed eyes. Link to post Share on other sites More sharing options...
