Leica Super-Elmar-M 21mm f/3.4 ASPH. Reviews

Superb Lens

The lens is well known for exceptional sharpness and that really came home when I paired it with a M10 Monochrome. The tonal qualities rendered are extraordinary too.

Possibly Leica’s best lens?

By Douglas

No hyperbole... definitely one of Leica’s finest lenses, and as we know that’s saying a lot. Compact, superbly designed and built, sharp enough to cut yourself. Works stunningly on M and SL bodies, with an incredible amount of detail and clarity without distortion - to the corners. I’ve actually used this lens on Sony’s A7R/S with a Novoflex adapter and the results were outstanding. If you like this ultra-wide focal length, you’ll thank yourself for buying this lens. A real keeper.

Second review after 3 years

I'm leaving a little gift here, see photo. Now, this image passed quickly through lightroom. That said, this is what one can do quite easily if you don't overexpose your image. I love this lens. When in New York with my 35mm lens, I wished for something wider. When I'm out in nature, the 21mm can pull things in without walking backwards. It feels more natural to move in closer if one wants to tighten a shot. You can tilt the lens and pull in some foreground objects to add interest to the image. Leica lenses capture colors, or render then like no other lenses. It kind of strange, and subtle. If you are tuned to color, not all people are equal here, you will love what you see. Likewise, when you tweak the saturation and colors in lightroom, the Leica has them all. If you don't overexpose the image, the dark shadows come to life and becomes more of what the human eye sees in reality. Our eyes change exposure as we look around a scene, though you know that already. Nonetheless, the lens has some majic to get the light on your sensor so you can play with it later. Leica does it like no other, which is why I use my Leica 240 even though I wear glasses and my eyesight isn't so great anymore. I like the process and challenge of manual focus and the rewards this lens gives. I usually am not so technical anymore about sharpness and things of that nature. Leica hasn't failed me with any lens that I own, build quality is always perfection. I rarely carry a tripod anyway. Only a tripod and patience will give you ultimate sharpness. I carry my Leica because it's not the monster my Canon 5Ds is. The manual focus slows me down so I don't fire off 100 shots subconsciously thinking that I must have caught it all. The photo I uploaded was, again, on a fishing trip. I brought my Leica even though I knew it was up for abuse on dirt roads and water. As I was driving home during sunset, I spotted a patch of beautiful aspen a way off the road. I pulled over, did a short hike, and captured one of the most beautiful scenes of spontaneous beauty. I think we all want to be prepared when these moments pop up but seldom are. Many landscape photographers can spend hours seeking, traveling, planning, hiking and hoping. Outside of those grand efforts, I like to throw my fancy expensive Leica in a bag with this 21mm lens and my 35mm and hope I cross paths with something special. I highly recommend this lens on many levels and even for things I haven't though to write here. It's a great lens to have in your bag when an unexpected scene arises and a wide angle lens is what you need.

Stunning!

Great contrast and color, super-low distortion. All the other rave reviews are correct - this lens is a stunner. If you want to go wide, this is your lens.   I'm loving it on my M10-P. I can either use live view or my visoflex, or, you can use the entire optical viewfinder even outside the 28mm frame lines and it's pretty close to the 21mm field of view.

Super sharp, excellent build quality

By John

Combined with my M10, this lens produces exceptionally sharp images from edge to edge.  The build quality is very high, I like the focus tab on this lens.  Using the M10 live view mode, thus far I have not purchased an external viewfinder, and think I can work with this lens in that way (time will tell).

What can I say - everything I expected!

By Roland

This lens has lived up to all the previous reviews, and performs with typical Leica eye for perfection. It is massively sharp, corner to corner and everywhere in between. I have found it very easy to use on my M10, and I rarely, if ever, feel the need to use my Visoflex. I find that the image is easy to frame in the rangefinder, assuming everything I can see is going to be captured. The huge depth of focus makes focusing a walk in the park. I had hoped this would be my last Leica lens, if only for fiscal responsibility, but I do have my eye on the 135mm next. Love it!!!

Perfect Wide Angle Lens

I use the 21mm Elmar with my Leica SL2-S. I love the quality of the pictures, which are bright and crisp. Very good at all f stops. Manual focussing is a breeze and helps to fully compose a picture.

Disappointed on the SL2s

By Mark
Rated 3 out of 5
Date: 2021-09-01

While a great size, build quality and colors are typical Leica great, I bought this lens for the SL2s and would say that the performance takes a hit over using on an M camera (to be expected). Less sharp and distortion is relatively high in the outer zone - correction of the distortion reduces micro contrast and makes the images a little flat. Does not balance very well with the SL2s either, the camera is a little big for it. Typical of wide angle manual lenses, this one is hard to focus at wide aperture (not uncommon for manual, wide aperture, lenses).

does this include the front cover ring and rounded lens cap like the Summilux 35mm Aspherical?
Asked by: Erick
The lens hood is rectangular in shape and is produced out of metal which is similar in design as the 35mm Summilux. Both have a plastic rectangular cap that snaps over the front of the lens hood. Neither the hood nor the cap is round on either lens. Also there is no front cover ring for the filter threads included with this lens.

question

To use this lens on an M-E must you use a special viewfinder?
Asked by: John H.
You do need a separate view finder to frame your shot correctly. The bad news is it is pricey. If I am not mistaken the M-E does not have Live View otherwise you could just use that. The good news is the EVF really does help a lot. Once you start using it, it is really hard not to use it. On the 21mm Super-Elmar this is my favorite lens. I use it a lot for landscape photography. It is really easy to focus for landscape photography given you are almost always at infinity. The lens it self if really sharp, compact and light. The only negative is the lens cap is a little gimmicky and comes off easily. Other than that great lens.
