The problem is that most photographers use them wrong. Just thinking that it is a lens that will cram more field of view on to the sensor is bound to lead to disappointment and complaints about "distortion". For instance macro photography of model buildings etc. requires wideangle lenses to get a natural-looking perspective. Emphasising fore- vs. background is another use. Or taking a scene within a scene. 6 1 1 Quote Link to post Share on other sites More sharing options...

Or taking a scene within a scene. Surely this is just semantics, Jaap? If you are meticulous about levelling your camera, or more accurately having the plane of the sensor perpendicular to the image you wish to capture, and you’re careful about the corners, then no - distortion won’t be an issue. If you’re not careful, you won’t get a “natural” image, with egg shaped heads and curved lines. I agree that is strictly an issue of perspective, but calling it distortion is still correct. Distortion (in a lens sense) is a different issue - barrel distortion, moustache distortion etc ... but I do think it’s misleading and unhelpful to say “wide angle distortion does not really exist”. Of course it does, 2 Quote Link to post Share on other sites More sharing options...
pgk Posted March 16, 2020 Share #23 Posted March 16, 2020 FWIW I should have added that friends have used 24mms as their 'standard' wide angle (none use Leica though) so the focal length certainly does have its afficianados. 1 Quote Link to post Share on other sites More sharing options...
jaapv Posted March 16, 2020 Share #24 Posted March 16, 2020 Egg-shaped heads are no rectilinear (pincushion) distortion as is often thought. It is perspective distortion, caused by the lens being so close to the subject that the size relationship between front and back of an object differs too much compared to the perspective of our eye. As such it is not a function of the focal length of the lens, but of the distance between lens and subject. Simply said, the perspective distortion is the same for all focal lengths if used at the same subject distance, but it will be cropped off by the more narrow field of view of the longer lens. Wikipedia: Quote In photography and cinematography, perspective distortion is a warping or transformation of an object and its surrounding area that differs significantly from what the object would look like with a normal focal length, due to the relative scale of nearby and distant features.

jaapv Posted March 16, 2020 Share #26 Posted March 16, 2020 If you were a fish it would be the only undistorted view. It is a mathematically undistorted projection of the lens, but it is a discrepancy with the view of our eye, which has a more narrow field of view and gets its wideangle vision from scanning - and has a curved retina. That is why a swing-lens camera like the Horizont gives an "undistorted" view. It is a clever trick, really. The lens moves in a curve and the film is curved. Welcome, dear visitor!

mdemeyer Posted March 16, 2020 Share #28 Posted March 16, 2020 (edited) Working on a series of photos for a winery in Napa and used the 24 F3.8 Elmar extensively in their tasting cave last Friday. Here’s an example, probably at F8.0 for depth of field. M10 on a tripod. Framed with the LCD on the back I love this lens! Welcome, dear visitor!

But it sat on the shelf too much, being in between my favorite 35 and my 21. +1 But I didn’t sell and I never will, very nice rendering. A 24 is destined to be used not as often as midrange lenses. That is for me no reason to sell it. I don’t like a 21, perhaps that’s also a thing. I jump with pleasure to 15mm and this is how it is for me. 2 Quote Link to post Share on other sites More sharing options...
IkarusJohn Posted March 16, 2020 Share #31 Posted March 16, 2020 Odd, isn’t it? I like the 50, probably prefer the 75, don’t like the 35, really like 28, never got my head around 25 (Zeiss), enjoy the skies of the 21 and liked the 15 (Zeiss - Italian flag got to me).

newnew Posted March 17, 2020 Share #35 Posted March 17, 2020 I have the SEM 21, and Summilux asph 35mm. I like both lenses and use them depending on the situation . However the 21mm is sometimes too wide, especially if people are integrated into a landscape background or for street photography. With the 35 we are already out of the ultra wide angle space definition. I have an Elmarit 24 asph and I am delighted by its performance both in colour rendering and special signature. It is a great compromise between a 24 and a 35 as it is as well good for landscapes as for people and street. I have taken it for travel in japan and made some of my best photos, in a combination of 24 Elmarit, 50 Cron and 90 Macro Elmar. I was also tempted by the 24 Summilux but agree with Adan's comments , as it would not really bring any bigger benefits versus the Elmarit Asph. I wold really recommend to try that lens which , in addition gives a really special point of view. As to the finder , I use either a dedicated 24 or the visolux and the problem is gone.

Anyway I don’t get what you mean and I don’t know if the image is from a 21 or from the 24. I think a 24? I would like to agree with you but I’m not sure of the content. Btw, one more reason I prefer the 24 above a 21 is that a barely need a separate viewfinder. I use the metal frame of the finder as the 24 frame and that goes quite well, sometimes I have recompose but not so much. 1 Quote Link to post Share on other sites More sharing options...
darylgo Posted March 17, 2020 Share #37 Posted March 17, 2020 One more reason to love the 24 Elmar M 3.8 is it's diminutive size, if I want to carry a wide with minimal weight (backpacking) this is my go to lens, along with the equally brilliant 50 Summilux. The lens is magical for it's beautiful rendering of landscape, I'm looking forward to seeing what it will do with the rumored M10-R. What I find so anti-M about it's alleged demise is that it meets all the criteria for what the M is about, small, basic and superb IQ. What is Leica thinking? 2 Quote Link to post Share on other sites More sharing options...

I meant the 24 was a good compromise between a 21 and 35. The picture is from a 24 mm showing the fine colour shade separation of the Elmarit. 1 Quote Link to post Share on other sites More sharing options...

Any perspective issues (which can sometimes be the fault of the photographer) can be fixed in seconds in Lightroom. It is a superb little lens which can be heartily recommended.

james.liam Posted March 18, 2020 Share #40 Posted March 18, 2020 (edited) My favorite FL when I shot Nikon digital and film. Had the 24/2 AIS for years and later on, the 24/1.4 G. Really preferred it to both 21 and 28. On RF, not so. Have a 28 Elmarit and 21 SEM. Recently bought a ZF 2,8/25 for my film Nikons. Fantastic. Perfect FL on an SLR.
