I think measuring from the flange, without screw, is ok.

So far:
Fujita 135/4.5 has the smallest diameter
Raynox 135/2.8 has the shortest length.

My 100mm measurement included the screwmount as well as the rear cap.

Chinon 135mm F2.8 78mm top to toe.

It's not too fat either at 212mm around.

Well, I supposed my Vivitar 135/3.5 was very small (about 90mm length x 54mm diameter at mount) but reading here it is not Smile .

The early M42 Takumar 3.5/135 is really small. Not sure of the dimensions but I used to slot it into any pocket. Sharp too.

Edit: See it's already been mentioned.

Are you sure about that?...212mm is over 8" in diameter!!!

This is one of those girth vs diameter situations. Wink

Perhaps we should turn to volume now? Wink
My reference is still the K-mount M135/3.5 which
is 64mm in diameter and 66mm in length, not counting screw/bajonett.
This gives me a volume of 212 cm^3 (V = pi*r^2*l).

Can any M42 lens beat that?

That is an astonishingly flat volume. Laughing

well, put in volume, my Vivitar has about 206cm^3 . EDIT: looking back at the thread, it seems identical to Dollonds.

I think there are not so many threads around the web about who has the smallest one . Smile

To equalize the difference in 'speed' you need to multiply the volume by the F number Very Happy

Great idea. Very Happy


Just as an academic exercise, here is another way to obtain a very compact 135mm:



On the right is my Soligor 135/3.5. On the left is a Nikon 50/1.8 Series E coupled with a Soligor 3x TC. The combo on the left measures just 63mm from the flange, or 68mm including the mount protrusions. The width at the widest part is 62mm.

Granted, this combo produces a 150mm equivalent. But if you replace the 50/1.8E with a 45/2.8P, the focal length would be an exact 135mm and the package length would shrink by 7mm to just 56mm from the flange or 61mm including protrusions. Very compact indeed! Shocked "Cheating" aside, I believe this is the shortest so far...
