Hi guys.I want to buy an ultra wide lens for monochrome and SL type 601 . My budget is limited. I suggest that the M 21mm f1.4 lens buy $ 4,000 (a good field, but now it's expensive for me) and also a 21mm voigtlander. You guide me. Do you suggest another lens? What can I do with my limited budget? Thanks

Thanx Pico,but 10mm is no sharp and i have 12 mm now, i want 20 or 21mm . 21mm very tempting focal for me. 21mm leica is like new but not have hood, voigtlander is good price , i am confused, need help. 24 mm is tempting too . I have 12mm voigtlander, 35 and 50 and 75 mm leica now

Kamyar ,the 21 SEM is fantastic if you can use f/3.4; probably the sharpest 21 out there, if that is what you are after.

I don’t use a 21 much, but have been very pleased with the Voigtlander 21 f4.0, on both the M9 and especially the M10. It has slightly colored edges on my M9, but much cleaner on the M10. I especially like its tiny size. The 21 SEM would by tough to beat, and is also nicely small, but too expensive for my little use of a 21. The Voigtlander 21 f1.8 has an excellent reputation and good speed, which is what I would consider if I needed a fast 21.

The Voigtlander 21 f4 might have worse colored edges on the SL, but should be fine on the monochrome.

The 21/1.4 is huge, heavy, pricey, and optically not that remarkable at large aperture in my opinion. I suggest the CV 21 or if speed isn’t critical, the 21 SEM or the CV 15.

I love the CV 21/4.

What do you think about leica r 24mm f2.8 Rom?

[lct]

What do you think about leica r 24mm f2.8 Rom?

 

It is outperformed by modern M lenses including 24/2.8 asph. One of my least used R lenses i must say.

What do you think about leica r 24mm f2.8 Rom?

 

Generally considered to be one of the lesser R lenses, which is reflected in its price.

 

You might consider the excellent 19/2.8 Elmarit-R v2.  The v1 is not quite as good.

I can’t understand!!!

[Gregm61]

The 24mm f2.8 ASPH-M Elmar may be the sharpest M lens I own.

Lct wrote that modern M lenses are better than R 24mm lens.

 

...

my opinion:

Elmarit-R 24mm...

This is old design from Minolta 1974 adopted and adapted to R mount by Leica (with different glass).

 

This older design of 24mm R is outperformed by modern Leica 24mm as Elmar-M 3.8/24 or even older  Elmarit-M 2.8/24 Asph.

 

21mm:

I have and use some

Zuiko OM  3.5/18mm and 2/21mm soso lenses but usable

Super-Angulon 4/21 with border not very good

Nikkor 4/21 this is nice on M too

 

My prefered since more than decade and usable on 24M sensor Elmarit-M 2.8/21 Asph. this one is now very affordable and best value for money.

For 21mms I have used both the Leica 21/3.4 SEM and the Voigtlander 21/4. The SEM is better for sure - sharper, better contrast all over and has been rated one of the best Leica lenses in those aspects. But I sold it for the Voigt 21/4 (v1 LTM version) simply becos I don't use 21mm very much, mainly for travel, hiking, landscape and those are rare as I shoot more street. For its price Voigt 21/4 is great and it's so small and light - so easy to take along for long hikes.

 

You also went into 24mm. Most people who have the Leica 24/2.8 swear by it. There's also the Zeiss 25/2.8 which is reasonable and very good as the reviews go.

 

Most people who have to decide between 21 and 24 (or 25), including myself, decide it based on distortion - most agree that 24/25mm is the best balance between wide angle and less distortion. Hope that helps.

The 24mm f2.8 ASPH-M Elmar may be the sharpest M lens I own.

 

True, but isn't it 24/3.8 ?

[darylgo]

Leica has many many great lenses in 21 and 24mm.  If your looking for the technically best M lens the 24mm f3.8 Elmar-M Asph would edge out the others but in practical terms any Leica M Asph lens in that range will not disappoint you.  For the SL the 24-90mm is good throughout it's range, 24mm (zoom) edged out the Elmar-M in my testing, the 90mm end of the zoom range is not as good as the primes.

I was mislead by the requisite for an Ultra-Wide lens which today is 10mm.

Maybe it is better to address the subject as '21mm'.

"Hyper wide", "super wide"... I don't understand those new appellations. To me an ultra wide lens has always been wider than 28 but i may be wrong. Never used a wider lens than 15mm BTW so no hyper-super-ultra-wide lens for me anyway .

Hallo,

Look here: Leica M

Understandable. If you were to try, for example, CV's 10mm lens it might profoundly shift your expectations. This kind of innovation happens only once in a generation of lens development.
