One just showed up in the Marketplace.
Maybe I should clarify that I would like to have it have auto focus as well. I think the Sigma 85 would do as well, but it isn't available new which is a bit of a negative. I'd rather have a DFA 85.

There is no starless DFA 50mm that people could confuse it with. The previous 50mm lens is FA. So it's pretty clear what people mean when they say DFA 50mm.

Pentax also believes this is the best lens they've made in the modern era, at least in terms of image quality:
IQ is not only technical data of lens.

The challenge for Pentax and the lens roadmap is that there is no universal definition of the required line-up. In fact, the 2018 Pentax Survey (2018 Pentax K-mount DSLR User Survey - Photo Industry News | PentaxForums.com) proves there are no lenses at all that "everyone" wants. There's aren't even any lenses that "most people" want. The biggest vote getter was only wanted by a tiny niche 6.2% of the participants (and those are just hypothetical votes rather than cash-on-the-barrelhead commitments to buy).

Worse, even if Pentax makes an 85, most of the people who want an 85 will be unhappy with it and witll complain bitterly on PF! (As they did with the DFA* 50/1.4.) The Survey proposed three different 85 mm variants and the votes were almost evenly split among f/1.4, f/1.8 and f/2 variants at different price points. The people who want big flagship DFA* 85/1.4 won't be happy with a slower lens and the people that want a smaller, less expensive 85 won't be happy with behemoth, $$$$ fast lens. Interestingly, more people wanted an updated 77/1.8 than wanted an 85/1.4 or any other 85 mm variant.

Nothing new! Regardless, there will be some who are really happy with new big lenses. Iím looking forward of getting 85 and wide prime. I can still remember when DA*55 came and it was treated as huge too expensive lens for what it is compared to FA50 and F and A and K and also tak.50....much has changed since then? I hated that I did not jump on DA*55 earlier. I was put off by these íreviwesí. Will not make same mistake again.

The photo below shows the four something-to-300mm AF lenses I currently own, which cover a period of 23 years {I purchased (a) in 1995 and (d) in 2018} - all fully extended:

(a) Canon EF-mount 75-300mm f/4-5.6 476g

(b) Sigma K-mount 70-300mm f/4-5.6 536g

(c) Pentax-DA K-mount 55-300mm f/4-5.6 464g

(d) Pentax-DA K-mount 55-300mm f/4.5-6.3 PLM 442g


(a) and (b) are FF

(c) and (d) are WR

(a) and (d) have in-lens motor and electronic aperture control

All are roughly the same size and weight; this kind of observation is why I believe Pentax could concentrate on FF lenses for a while; we APS-C users would end up paying more, but I doubt if the FDA lens would be much larger than a comparable DA lens, and APS-C users do have a more modern collection to choose from.

Yes, some DA lenses could be refreshed with electronic aperture control and in-lens motors, but many of the FF lenses are even older than DA {some not even AF}

It means more than diddly squat. It just isnít the whole story. Such tests compare one lens to another in controlled, identical conditions and seeking comparative information for specific, tested qualities.
Testing individual lenses on individual cameras adds real world information to the objective test data so users can make truly informed compare and contrast decisions. Both have value.
yeh... but testing lenses on a camera just carries far more weight than some lasers pointed on a perfect sample in a lab...

I think that Pentax users of K-1 want the line of lenses close to old one and ASAP...

I'm not sure that we will see such line of lenses in the nearest years...

Some people want new lenses, others are complaining about them.

It will be hard.. very hard to achieve, perhaps not impossible, but extremly hard.

What I see is that Pentax have 3 main systems. APS-C, FF and MF.. all of their users wants products, all have specific needs and the worst part is that ALL of them want this products FAST, and sadly that can't be done, not for a small division such as Pentax. In the last 2 years they focus the effort in the FF system, but we can tell that is not fast enough

That is why I would like to see them work on DFA {no star, so less 'effort'} lenses - not quite 'perfect', but usable on both APS-C and FF cameras.

Wants and needs were different back then. For example, the best modern zooms (such as the current DFAs) already cover much of this ground extremely well, and most people would just perform the effects of the 'soft' lenses in PP. I don't think many modern Pentaxians would really want, use, or buy many of the lens variants above. Some of the best are still available (and still unique and fantastic!), and there are also some new primes that are far better than the former version(s), even though the spec may differ slightly from the former version(s).


Pentax is in the process of filling out the few key gaps. But it would also be great to eventually get some of the unique 'differentiators' back in the lineup, such as the 200/4 macro.

I see "FA*200/4 macro" in @Ogl's list.

Well, currently in the line up, Pentax has FA 31, 43, 50, 77. DFA 50 macro and 100 macro WR. DFA *50. DA *200 and *300. DA 560. All are considered full frame compatible. In addition, of course, several lenses, like the DA *55, DA 50 f1.8 and DA 40 are usable on full frame although they may have dark-ish corners wide open.

Beyond which, most of the lenses you have listed there are easily obtainable on e bay. I bought a FA 135 f2.8 pretty recently and it wasn't expensive at all.

Long story short, the middle of the range is actually pretty decently covered with primes. It's the wide angle that is currently missing. But honestly, if you are shooting full frame with Pentax, you should be able to make do with lenses in the line up currently, even if there are others you are thinking about in the future.

This is especially true if you also factor in the modern zooms, like the DFA* 70-200 f/2.8, that are optically at least as good as most primes across their FL range. The DFA 15-30 f/2.8 is no slouch either if you want wide. The days of zooms being a distant second-best are past.
