Prototype lenses?

As shown on the Dutch Pentaxian.BE/NL, het beste dSLR Pentaxforum - Forumindex:

On the following Flickr stream a transparent K-5 is shown but also a few interesting lenses...



Interesting is not only the gray SMC Pentax-A* 135/1.8 and the silver Takumar-DA 40/2.8:



But also the following lenses, which are *not* DA 35/2.4 or DA 35/2.8 Macro Limited lenses (the knurled rings are different):



Any ideas as to which lenses these might be?

I only know about the Takumar DA 40mm... Since you already have the name down you probably googled it already
Takumar-DA 40/2.8 AL Limited

Yup, that was the obvious one because of the AOCo logo on the lens cap

The DA's are possibly prototype macro lenses? Because these look so similar to the DA 35/2.8 Macro Limited.

Hah - just posted this on DPR. I think the two lenses behind the DA35 Limited are new (neither appear to be the DA-L 35 2.4). Interesting fuzzy-pic stuff; the one in the back looks like a macro but both are longer physically than the DA35 Limited it appears.

Also, considering both the rarity of the Pentax 645D *and* the show-room K-5 translucent body (which this poster also appeared to have access to), I'd say these shots are coming out of Japan and someone associated with Pentax quite likely.

Whoa! I now also see that it's the SMC Pentax-FA 28mm F2.8 soft behind the DA21, and the SMC Pentax-FA 85mm F2.8 soft. So it's definitely a nice collection of lenses. But I noticed on DPR that you've already seen that.

The Spotmatic is the very first version (with the small meter switch) and the 8-element 50mm F1.4 Super-Takumar.

It's kinda funny how there's some Japanese printed on the lens in the back (the place circled - you can make out some japanese Hiragana or Katagana)

Interesting! I was just going to say that these must be prototype WR versions of the DFA 50mm... but I think maybe the lens diameter looks too small for a 2.8 50mm?

I would guess a wide 28mm or 24mm? with DC motor and plastic body, the focus ring looks to have similar style with the DA35 2.4

I seem to recognize "... L* 2.1" or something!

The grey A* 135/1.8 is interesting. It seem to have the same color as the A* teleconverters and the grey part of the white long telephoto. It could be an early prototype - Pentax may have considered this color scheme for the A* lenses. However, the patterns on the focusing ring is different from all A-series lenses; or is Pentax planning to reintrodduce the A* 135/1.8? After all, Zeiss is selling high-end manual focus lenses....

The photo stream is from the person who maintains this (Japanese) blog; the Google translation is super bad (as usual with the Japanese language) so I still don't know:
