Looking for Someone Who Knows the All About Pentax Macro Lenses

Hello-

New the forum here! I write a blog and I have been trying to put an extensive list together of as many macro lenses as I can just as a resource. As primarily a Nikon shooter, I am quite new to the Pentax system. I was wondering if someone or a few of you could help me but posting what other lenses specifically Pentax has to offer (macro). This includes M42 mount - K mount - etc. Also if you know of any macro designed only for Pentax (such as Tamron had a 300/2.8 [90E] that was designed solely for Minolta I think, perhaps Pentax too).

So far I have:

Manual Focus -

Pentax-A 50mm f/2.8
Pentax-K 50mm f/4
Pentax-M 50mm f/4
Pentax-A 100mm f/4
Pentax-A 100mm f/4 Dental Version
Pentax-K 100mm f/4
Pentax-M 100mm f/4
Pentax-M 100mm f/4 Dental Version
Pentax-A* 200mm f/4 ED

Pentax-K 100mm f/4 (bellows)

Auto Focus -

Pentax 30mm f/2.8 DA
Pentax-F 50mm f/2.8
Pentax-FA 50mm f/2.8
Pentax-D FA 50mm f/2.8
Pentax-F 100mm f/2.8
Pentax-FA 100mm f/2.8
Pentax-D FA 100mm f/2.8
Pentax-FA 100mm f/3.5 (Cosina)
Pentax 100mm f/2.8 WR D
Pentax-FA* 200mm f/4 ED-IF

-

And the above are what I have found so far, my info may not even be correct. As I said, I am new to Pentax so like all systems, all the acronyms and letter designations are very new to me.

I am looking even to the most obscure so don't hesitate! I will gladly add your usertag on the site as well as contributor. I appreciate the help and am looking to create the list for everyone. The blog is MakingNotTaking.blogspot if you were wondering where this is going.

Have you looked in the lens review database here?
Pentax K-Mount Bayonet Lenses - Pentax Lens Review Database

There isn't a macro specific section, but they're all primes so that'll help

Two of the AF lenses should be as follows:
Pentax DA 35mm F2.8 Limited Macro
Pentax D FA 100mm F2.8 Macro WR

what you also need to do, aside from listing the lenses and maximum apertures, is list also the maximum magnification ratio,

The macro takumar 50mmF4 preset can do 1:1, all other macro takumar 50mm lenses and all SMC and SMC-M and SMC-A 50mm macros and all 100mm manual focus macros (k mount or M42 mount) focus to 1:2. furthermore, most manual 50mm F4 macros and most 100mmF4 macros share the same optical formulas, it is only coatings and cosmetics that are different, as well as (perhaps) aperture blades.
