I'd check the 645 lenses and discoverd that this area is quite undocumentated.
So i'd prepare a list with production years for all 33 lenses (Pentax 645 MF & AF):

Some years are already known. For some more there's support needed.
If anyone has corrections, please let me know.

Great project. Thanks, And I'll see if I can help...

The next step has been the creation of an Pentax 645-mount lenses timeline:

I'm sure that the 33-55 and the 55-110 were released simultaneously. I believe it was in 2002 but could have been late 2001.
I'm also pretty sure that the 150-300 was was release sometime later. Perhaps a year or two.

No FA645 lenses were release before the 645N body. It was released very late 1997.

[angerdan]

Thanks På, i did a update to the wiki timeline.
Will update the list later.

[angerdan]

I did some more additions and corrections in booth the written list and the wikipedia timeline.

Currently i'm without publications for following years:

• 1986-1989
• 1991-1996
• 1998-2002
• 2004-2005

If someone can comtribute brochures, catalogs or pricelists for these years, please contact me.

In your initial list, is there an inversion between DFA and DA 25 mm ? I always thought it was DFA first, then DA (as in your chart 2 posts below)

The DFA certainly came before the DA 👍

Thanks, i'd fix the list entry

[texandrews]

Is this list done? I don't see any with question marks.

Also, is this just for Pentax lenses, or do you want 3rd party ( Like Hartblei)?

Currently done, but some years are unprecise. If somebody has catalogs frome theese years, let me know:

• 1986-1989
• 1991-1996
• 1998-2002
• 2004-2005

The timeline is only for common Pentax lenses.

A couple of errors here, Mr. Anger :

1) no mention of the "A 75 mm f/2.8" (only the LS 75 mm f/2.8 is listed from 1984 to 1993).

2) "A 150 mm f/2.8" is incorrect, we should read "A 150 mm f/3.5".

Hope it helps

1. no mention of the "A 75 mm f/2.8" (only the LS 75 mm f/2.8 is listed from 1984 to 1993).
2. "A 150 mm f/2.8" is incorrect, we should read "A 150 mm f/3.5".

Thank you.
Both is fixed now at wikiepdia and the image.

Would be nice if Pentax could continue te lineup with new lenses

[RICHARD L.]

My "discovery of the year" in 2020 was the wonderful performance of Pentax 67 lenses with the '67 to 645' Pentax adapter on a 645Z. They proved to be super-sharp, exhibit true-to-life color reproduction and produce a deep contrast unseen in 645 lenses. Some of these "utmost" lenses (like the P67 late 200 mm f/4, 165 mm f/2.8 or 55 mm f/4) can be bought used for only a few hundred dollars on eBay. A couple of the most sought-after lenses unfortunately sell for insane prices used (P67 105 mm f/2.4 for over 800 US $, M* 300 mm f/4 for over 1000 US $ and the very rare 75 mm f/2.8 for around 2500 US $).
