Pentax? Are you listening?
Pentax' brochures have always been fairly bad. I remember seeing print brochures full of errors (about filter size, QS,..). The colours that label optical elements (like ED) are applied inconsistently and vary between publications. So I am not surprised the lens roadmap is inconsistent, as well. Its almost as if the person putting it together is not a photographer, but a marketing person.
Anyway, not really much news from this chart. Good that things keep moving, but I hope there will be some surprises

Why would the DFA 150-450 be inappropriate in this context?
It's not as if an APS version would be smaller...
The wider part? The 150-450 is excellent, I wouldn't want a worse (even slightly) lens to get it down to 80mm...
I have read some feedback that some DFA aren't as fast on the k-3/II. Also, I would like something a little lighter. I hope it would be a little bigger than the 55-300. Like I said I'm dreaming out loud.

I don't find it surprising. The new lens only works with a small subset of Pentax cameras for now.
I think I read that the new one would replace the old one. Good to see that's probably not the case.

The optical quality and f/stop range are more important to lens size than the sensor size for the same focal length. I would not expect that size and weight in a lens with more than 2x longer optical reach and a zoom range of 10x rather than 6x. Look to the 50-500 for an idea of what to expect from a 10x zoom and compare to say the 150-500 for size and f/stop. Note that these start at f/4.5 not f/3.5...

Pentax now really does have a lot of lenses, don't they? I'm counting 40. Although this is cheating a bit, with the rebadged Tamrons and 40Ltd/40XS, it's still good to see.

as the one OP posted as well... second page at least

and sorry not to pay attention that only the first page was June 2016. I thought it is the same road map.

As far as the DA* lenses being updated I would think Pentax would be looking for synergy across the DA and DFA formats.

What I mean is that Pentax has limited resources so IMO it would make sense for them to design * lenses that work well on both DA and DFA where possible, particularly primes. For example, if the DA* 300 is updated I would expect it to be as an official DFA optic (yes, it's listed as FF compatible anyway). Similarly something like the 55mm I would think would become a DFA officially.

The DA* 50-135 is a lens I wouldn't want replaced with a full frame version. The purpose of that lens is to be a 70-200 equivalent. The DA* 300 on the other hand makes sense to be updated as a DFA.

One lens on the road all other others already in stores. This is the most pointless roadmap ever.
OK, it could be worse, they could drop one more lens.

Also, they update fluently, which is rather a good sign.

I would like to see an update of it though.. with the HD coatings and a faster motor. If they can somehow make it sharper at f/2.8 that'd be super too

OTOH the 50-135 f/2.8 on FF is equiv to around 70-200 f/4 right? A FF 70-200 f/4 WOULD be nice imo.
