Smallest M Mount Lenses

[jsrockit]

I'm aware of a few very small M mount lenses (or LTM lenses) ...

MS Optical Perar 35mm f/3.5
Canon 25mm f/3.5
Canon 28mm f/3.5 (and Seranar)
CV 28mm f/3.5
CV 21 25mm f/4
Leica 35mm Elmar 3.5
Leica 35mm Summaron 3.5
CV 35mm f/2.5
CV 50mm f/2.5
Avenon / Kobalux 28mm f/3.5
Leica 40mm Summicron (Minolta)

Some of these are super tiny (35mm Elmar / Perar)... what other lenses are out there that are smaller than the aforementioned CV lenses?

Let's keep the Leica 50mm Collapsables out of this thread since they are too big extended and if it is bigger than the CV lenses, let's keep them out of the thread too (and no pinhole lenses either). I want to see truly tiny lenses only. I know I'm missing some, so let me know what they are. Thanks.

Zeiss Hologon 15mm f/8. 😀

The Canon 28/2.8 is quite small, similar size to the 25/3.5. The Canon Serenar 35/2.8 is pretty small too.

Well, if Rokkor/Summicron 40 is considered to be small - than CV 40/1.4, 35/1.4, Summicron IV 35/2, Canon 35/2, Komura 35/2.8, UC Hexanon 35/2 will all be same small size

Well, perhaps the UC, but not the CV, Canon f/2 or Leica 35mm Summicron / Summilux.

nikon ltm 35/2.5

 

[stupid leica]

no way is the UC smaller than the Canon 35/2. I refuse to believe it.

 

[yanidel]

The 28mm Industar 69 is the smallest I even seen.

 

[tomele]

Leica 2,8/28 Asph ?

 

[kbg32]

28/2.8 Elmarit Asph., 35/1.4 Summilux. Both pretty small.

 

[Bingley]

I was going to mention the chrome Canon 35/2.8, but Darren beat me to it. It's smaller than the CV lenses on the list.

C Biogon 35/2.8 & 21/4.5? Monsters compared to the ones mentioned here, but still small.

 

[kermaier]

The UC-Hex has a wider front rim than the Canon 35/2 (43mm vs 40mm) but I bet it's shorter. BTW, the Nikkor 35/1.8 LTM is approximately the same size as the UC-Hex.

The Canon 28/2.8 has to be the smallest in its class, with the M-Rokkor 28/2.8 following it.

I would put the VC 35f2.5 II there, as well as the Canon 35f2. The problem with really tiny lenses is one of ergonomics. When they get too small - handling aperture rings and focus rings becomes difficult. I haven't tried the Perar 35f3.5 -but from the shots I have seen of it - it does look a bit fiddly to use.
On something like a M2, the Summicron 35f2 v1, the VC 35f2.5 II and the Canon 35f2 (all without hood) are probably as small as I would want them. The UC Hexanon 35f2 is also very compact - but not much different from the Summicron/VC/Canon.
The Hologon 15f8 was indeed small - though most of the lens was inside the camera body. However, the finder was huge - and you needed it.

Pinhole in a cap?

 

[sanmich]

How can this thread gone so long without the 50 f/3.5 elmar ? 😕

[edit] oh, ok...missed that one...

"Let's keep the Leica 50mm Collapsables out of this thread"

still, the elmar doesn't seem much larger than the Perar...

True about ergonomics. But I like the little focusing lever that some of these lenses have (eg the CV 28/3.5), I find it very quick and easy to operate.

It's little known, but there is a native M mount version of the Kobalux 28mm F3.5 - in fact I've owned one.

 

[David Murphy]

The Canon 28mm F2.8 and the Komura 28/3.5 at least deserve honorable mention. The Canon 28/2.8 is a lot smaller than modern equivalents, although its optical performance leaves something to be desired IMO (it's nicely made none-the-less).
