Fast pancake

[Rawfa]

Since I´ve moved to the NEX5 I´m really having a lot of fun with the 16mm/24mm sony pancake, but I do miss a lot a small fast mid range pancake (I never used to take the 20mm/40mm out of my GF1). Right now I have an adapter for Pentax K and for Sony Alpha, so is there any small fast pancakes between 35mm to 50mm (equivalent) for either of these mounts out there?

Does your pentax adapter have aperture control? Then DA 21/3.2 pancake is an option, reviewed here:

Otherwise there are bunch of larger K- M- and A- primes reviewed here:

If size is key factor, there is also a Voightlander 20/3.5 Aspherical Color- Skopar. You don't need aperture control on the adapter for this one. http://www.cameraquest.com/Voigt_SL2.htm

Does the rokkor 35mm f1.8 fit on the alpha mount?

You may be interested in the smallest lens that I've ever seen, the MS Optical 35/3.5.

I received mine last month, but, due to a previously mentioned injury, I haven't had a chance to really use it, yet. It is CRAZY small. Essentially, it only sticks out 4mm past the adapter when collapsed!

Additionally from being small I'd like it to be moderately fast. I might just end up buying a Pentax 24mm or 28mm f2.8.

The problem with Pentax pancakes is that the size of the adapter kind of brings you back to square one. You may as well just look at something like a Voigtlander 35/1.4 or Zeiss 35/2, since their adapters are considerably smaller.

As I already have some pentax glass and the adapter I ended up buying a 28mm 2.8 pancake.

Has anyone tried the 40m ultron on nex?
