Looking for the smallest (and cheap) lenses out there

Hi guys,
I'm looking to beef up the K-01 with some small (ideally pancake, but they don't have to be strictly pancake) lenses, without going too high budget - so looking at MF.
Optical quality doesn't even have to be insane - it's just a decent camera to throw in my bag when I don't want to use my K-5 and my big beefy stuff.
So far I have a 28mm f2.0 and the 43mm LTD (I already had that) - so I am looking for more like that but under $140 or so...

I tried looking on eBay for a 135mm, but they're all a bit big. Is there a smaller short tele out there somewhere? Other than that I'm interested in cheaper alternatives to the 70mm LTD and the 77mm LTD... I dunno if there were pancake 70-ish lenses back in the day...

Any suggestions? Thanks.

The smallest tele is probably the 100mm f2,8 macro WR. The DA 70 limited is even smaller but is less of a tele.

You might consider replacing the 28 with the DA21 limited, it's much smaller but also slower. And the DA40 Limited (or the absurdly small XS 40) are both smaller than the 43, but not better.

In fact the Da limited trio (21, 40, 70) are the smallest lenses out there in any system.

Something like the M 85/2 is pretty compact and a good lens, but would fail the budget (probably mid $200's).

Pancakes by their nature need to have a focal length similar to the distance from the rear element to the sensor plane which is why they are around 40mm on Pentax slrs and 17-20mm on m43.

If you don't mind manual lenses there is the industar 50-2, very small and tessar design so very good IQ. I always
carry mine attached to a M42 Pk adapter in a pocket. Keep it set at F4 or 5.6 and just focus.

I also put together a kit of small lenses for my K-01. The F35-70 f/3.5 zoom is one of the smallest zooms (about the size of a FA50), focuses fast, and is quite inexpensive.

M-series manual-focus lenses tend to be small - apart from the original "pancake", the M 40 f/2.8, the M 28 f/2.8 (first version, with the chrome band around the front) and M 50 f/1.7 or M 50 f/2 are tiny. The 28 is my preferred "walking around" lens, because it's small and easy to use hyperfocal focus.

If you can find it, the M 85 f/2 is about the size of a FA50. The M 135 f/3.5 is bigger, but still very compact by today's standards - probably the smallest 135 out there.

Have fun!

The 40 xs is pretty cheap for a prime.

I have an Albinar 135/2.8 that I got for $15 and it's pretty small. Not tiny but when I get home from work I'll put it next to my F 135/2.8 and see if there's much of a difference in size.

I have the M135 f3.5 and it's nice, compact and cheap but the minimum focus distance of 150cm is sometimes a frustration.

For a telephoto, how about the M100 f2.8? It's physically smaller, only weighs 220g and focuses down to 100cm. Also, it's in your price range. There is a A-series version of the lens too. I'm looking for that one myself, but it seems a bit rare and more expensive.

If you want anything wider than the 28mm you have, I would suggest saving up for the DA21. I got one for my K-01 after considering a number of older lenses. The alternatives aren't that much cheaper, they're all bigger and they miss out on modern conveniences like AF and distortion correction.

That's great advice, I forgot about that one, but indeed it's surprisingly small, and quite good optically.

A Vivitar Zoom?

70-210mm f1:4.5-5.6 Macro Focusing Zoom.

Only 1 cm longer and 80 grams heavier than the M f1:3.5 135mm lens mentioned already.
As a bonus it has A contacts.
And it has a slightly closer minimum focus distance.

I've used it, it's far from being bad, but it doesn't compare to a decent prime.

I first decided to try it because "fast focusing" was frequently mentioned in reviews. That was on firmware 1.0 - it does really well with FW 1.01. If it just wasn't so homely (I'm not a fan of the F lens styling).

The F35-70 is optically/mechanically the same as its (better looking) older sibling, the A 35-70 f/3.5-4.8, which doesn't have as good a reputation because the short focus throw makes it hard to manual-focus. It's interesting to see a negative feature become a plus.

Well, he'd probably want to change the charcoal-gray body to yellow, for starters...
