Type of lenses to go with a K-1

I've recently come across a K-1 that I am considering. What are the names of the lenses that match with this FF camera? Must they have the 'D" and "FF" in the name of the lens? Also, I see a lot of Sigma lenses for sale on the For Sale site. Are Sigma lenses considered to be of good quality (vs Pentax) and are there any Sigma lens codes/numbers/letters that need to be on the lens if they are going on a K-1.

For Pentax, any lens series except DA covers full frame. However, the DA* 200mm, DA* 300mm, and DA 560mm are exceptions to this rule, and you also can get away with using a handful of other lenses such as the DA 40mm Limited and DA 50mm F1.8 without much issue. It's the wider lenses that struggle: DA lenses on Full Frame: Test Shots thread - PentaxForums.com

For Sigma, look for "DG" and for Tamron, look for Di (not Di II).

This may also be helpful, though the third-party list above will be more exhaustive.

Buy an FA-77mm for your K-1, the combination produces incredible results.

I have a lot of SIgma lenses and I have been very pleased with them. I have recently purchased the Pentax 24-70 and it is rapidly becoming one of my favorite lens. Some of the older SIgma if you can find them are very good I have a 50m f1.4 HSM Sigma which is a great lenses and a 70-200 f2.8 HSM both of which are no longer made in Pentax mounts but to be found used.

The K1 is a great camera and I am sure you will pleased with it

I am very impressed with the Pentax full frame zooms I have. Back in the day when I used film I checked out Sigma and Tamron but ended up purchasing Vivitar Series I lenses because the image was clean and not grainy like the other two companies. So I would suggest keeping an eye on Vivitar Series I lenses if you want some older glass. It is subjective and there will be many who disagree, but I would never suggest a person buy Sigma or Tamron zoom lenses from the 1970's or 1980's to use with a K-1.

Whilst the DA*55 is not on the list its beautiful in FF. The DA70 Ltd is also good for portraits in FF.

The K-1 is a very toughly-built pro-style camera body, which includes weather sealing, or WR (Weather Resistant). But if a non-WR lens is on the camera, this feature is not in effect. Most 3rd party lenses are non- WR, although a few of their most expensive models are. For an all-around, versatile zoom lens of very high optical quality and very good build quality, the Pentax HD (for High Definition coatings) DFA 28-105mm f/3.5-5.6 ED DC WR comes highly recommended by virtually all users having this lens. The cost is around $497.

if you need to shoot fast action subject matter, and/or shoot often in low-light situations, then a pro-style "fast" zoom lens having a wider, constant-aperture capability, letting in more light affording a higher shutter speed in the same lighting, would be best, which is the Pentax HD DFA 24-70mm f/2.8 ED SDM WR lens. As you notice, to achieve this wider-aperture "speed", the lens does not have as much zoom range, especially at the longer telephoto end. It is also larger, heavier, and far more expensive. Usually about $1,297 but now on special at around $1,097. Check B&H (whichI just did), or Amazon, and Adorama.

You can also buy the first Pentax zoom zoom lens mentioned, then also buy a non-zoom lens- a "prime" lens of a particular focal length, such as the Pentax FA 50mm f/1.4 or FA 35mm f/2 (now on special at $272) which are not WR but are very "fast" lenses, offering very wide aperture capability, for far less money than a fast zoom lens.
