Yes, yes! You're on the right track! Those Super Tak 3.5's and that Dollonds look about the perfect size! I also found another old tele lens that's pretty small, dunno about the length though:

If were gettng primes under 200mm I would want to stick to to f2.8, or you might a well just use a 55-200 or 55-300 zoom which is about f4.5-5.6 and f4.5 at 135-200 range. (ok the 55-200 might be a bit soft full open)

What about FA 135 f2.8 lightweight(375g) compact (80mm long) and fast f2.8
SMC Pentax-FA 135mm F2.8 [IF] Reviews - Pentax Lens Reviews & Pentax Lens Database
It about the same size as a DFA100WR.



An M200/4 isnt really that much smaller or more than a stop faster than a zoom.

Well, you'd think that! But try to think outside of the (Pentax) box. Yes all of the M lenses 100-150 are moderately sized. (the 200 is a bit bigger than what I'm going for) but I could just as easily get a modern prime, the DFA 100mm WR and that's about the same size/weight.
Well, it's actually noticeably bigger/heavier than the M100/2.8, but definitely surprisingly compact taken on its own merits. I guess I was imagining you were also trying to keep the price down, and I did get the impression you really wanted longer. The FA135/2.8 is only barely bigger or heavier.

I'd say that if you really want it to be comparable to the kit lens in size, I refer you again to the DA50-200 - it's the only thing that comes close that I know of. The M200/4 is compact for a 200/4, but it is really is a lot bigger and heavier than anything else we're talking about here.

I know that a couple of companies made a 300mm mirror lens. That's the only other possibility I could imagine really fitting the bill.

Compact?!?!? Y'all call those great lumbering beasts COMPACT?!?!? No way! I'LL show you COMPACT! And CHEAP! It's called the Enna Tele-Sandmar 100/4.5. On the camera, it is smaller than a SuperTak 55/1.8, about 35mm wide and extends 35mm from the body at infinity focus. It weighs just 110g, less than 4oz. I have two -- one in shiny gleaming minty collectible condition that cost me US$22, the other that I use that cost US$7. Shipped.

But you'll say, "Rico, there's gotta be a catch! What's the catch??" And the catch is... it's meant for an Argus C3 camera, THE BRICK. Register distance is short and there are no PK adapters made for it. So I made my own. From a one-buck PK body cap. I dremeled a hole in the cap and used contact cement to glue the lens into it. I get infinity focus and it's nice and sharp, but with character. It's my go-to lens for unobtrusive street shots. It's so small, it just doesn't LOOK like a telephoto!

I can't really post a shot of my mod right now, but this link goes to some online images. The little silver lens, not the big black one, eh?

[ enna tele-sandmar ]

I'll try to get a shot up later today, after I escape from the PHOTOGRAPHY AND ART exhibition at the Georgia O'Keeffe museum a few blocks from our casita. And lunch at the O'Keeffe Cafe, reportedly one of the best in Santa Fe. Yum!

I figured you would be the person to ask about this RioRico!

That 180mm f/4 Voigtlander mentioned earlier looks like it has potential as a cream machine as well...

Here are the lenses I have on hand for size comparison. The first image is from left to right, a Canon FD 135/3.5, the M135/3.5, the K135/2.5 and the Auto-Tak 135/3.5.



I set the Canon aside. The background row is the Vivitar/Komine 200/3.5, K135/2.5, Auto-Takumar 135/3.5, and S-M-C Tak 150/4. The foreground has the M135/3.5 and the S-M-C Tak 105/2.8.



The Vivitar is bigger than the M200/4, 62mm filter so not a contender, but looks small where I keep it, next to the K300/4. So I think of it as small.

I think the price for the best ratio of focal lens versus physical size should go to the A* 300/4. It is tiny for its focal length and moderately fast aperture. In fact it is smaller and much lighter, than the 200/2.5.
Much longer, but very compact and light weight is the Tokina 500/8 mirror lens. It is one of the better mirror designs, with good contrast, but still unbelievably compact.

Yes yes, I am familiar with the merits of this lens! I have shot several interesting shots with mine, but unfortunately it both sticks out like a sore thumb with it's large front element, and weighs my pack down quite significantly.

Aah, the 180mm is a thing of beauty. The 150 doesn't retract as far into it's housing as I thought it would at infinity however...
