What tiny ~28mm lens?

As you may know, I own a few lenses. Including a 21mm, four 24mm's, sixteen 28mm's, and ten 35mm's, as well as various others. And I try to use them all.

But I have a favorite cache of tiny ultralight lenses, always in my carry bag: Enna Tele-Sandmar 100/4.5 (110g, 10 iris blades), CZJ Tessar 50/2.8 (110g, 12 blades), and pancake Meyer Helioplan 40/4.5 (100g, 12 blades). These are my favorite lenses for many situations, including the mountain passes I cruised today. They have a very 1950's German clear sharp image quality. And they easily go macro.

Alas, I am not yet happy. The Helioplan is a bit sticky and not different enough from the Tessar. I need something wider while tiny. Wider means, 30mm or shorter. Tiny mean under 150g. Ok, maybe I could stretch it to 160g, no more.

I want a tiny 28mm or shorter, to be part of my always-there kit, where I can stuff the whole kit into one pocket and hardly notice. I already have some candidates in stock:

* Paragon 24/2.4 (220g) -- my lightest 24 but much too heavy
* Tamron BBAR 02B 28/2.5 (230g) -- lightest fast 28, heavier
* Vivitar-Komine 28/2 CFWA (270g) -- fast, compact, heavier yet
* Pentax M28/2.8 (150g) -- almost light enough, but how is IQ?

When I have money again, I'll be looking for something lighter and funkier than the M28 (150g), to keep in that always-have lens pouch. I'd thought of maybe a SuperTak 28/3.5 but they're heavier (220-260g). If I can figure how to convert an Enna Sandmar 35/4.5 (60g) to PK mount, that will almost suffice.

So, the question: What is the tiniest 28mm lens you know of? Something with character, in the 100g neighborhood. Some cheap little jewel I can stick in my pocket. Does it exist? Am I dreaming?

Yeah, well, I intend to sell a couple. I don't really need the Tak Bayonet 28/2.8, nor the duplicate Makinon and Focal 28/2.8's -- I'll keep the Focal. But all the rest are different. That's the fun: comparing the taste of each.

Hello

I have a Vivitar 28mm 2.8 I bought last month who weights (by our kitchen scales) around 110/120 grams.
It’s a version K22 on the “Great Vivitar 28mm Bestiary (Great Vivitar 28mm Bestiary: Details).

Best regards,

I have the three 28s and the smallest/lightest is the Vivitar 28/2.8 CF (Komine, K02). It weighs in at 200gm. The build is not up to the same standard as my Tamron 28/2.5 (02B), but I guess that accounts for the extra 30gm.

I think that you need an M20mm f/4 at 150 grams. It's a very thin (almost pancake) lens. For DSLR use I would take an A 28mm f/2.8 over the M28mm for more convenient metering with the same optics. The F and FA 28mm f/2.8s are also pretty small at less than 200 grams each.

If m42 is OK with you I would suggest the Meyer Lydith 30mm f3.5, 10 blades, 195g.

Its bokeh has a lot of character.

M20/4 is tiny yes, but big dollar.
Meyer Lydith is beautiful ;-P

My best all around 28mm is also my smallest, the Pentax-F 28mm f2.8, better than the M but heavier too, maybe no character, expensive now. The ones I have at the moment:



Front is Tamron 28/2.5 02B, Tokina EL 28/2.8, Pentax-F.
Rear is Sears 28/2.8, Vivitar 28/2 K12, Sigma 28/1.8, Sakar 28/2/8

As you can see, no real tiny ones here.

So far, ddharriman's 120g Vivitar sounds like the winner. Douglas's Meyer Lydith is a bit heavy but I'm queer for Meyer so it's hot on my want list. Any mount is fine; my current lightweights are in Exakta (40+50mm) and Argus (100mm) mounts. Again, my goal is a small set of tiny character-driven affordable lenses of negligible mass and volume that I'll always have in my bag or pocket. Keep those suggestions coming! Thanks.

Industar 69 28mm f2.8 might fit the bill, never used one though.

Isn't that an m39 lens, with a short Leica registration distance? Will take heavy modification to make it work on a Pentax DSLR.

I would have to go with the F 28/2.8 here because it is about as compact as they come, AF and a pretty good performer. Of course if space was no object, I would take along the K 28/2.

Thanks. My goal is a lens that's light+tiny, with a period feel, which means MF not AF, and speed isn't important. My Komine 28/2 CFWA (270g) is hard to beat optically and it's not too huge but it's still larger and much heavier than I want for this mini-kit. The pancake M20/4 (150g) is very tempting. All I need is money. The small-version Vivitar 28/2.8 (~120g) looks like a very good candidate, depending on how it renders. Ah, if only Meyer or Steinheil or Enna had a 25/3.5 or f/4.5 around 120g...
