So the D FA 70-210 (with hood) passes? ;)
Also, you do realize that the K-1 with 50-135 is heavier than a KP or K-3/5/7 with the 70-210 right? In fact, by about as much as the weight difference in the lenses. Or you can just use the 50-135 on a KP and save yourself a whopping 300 g.
Point is, why complain about the lens weight (which isn't *that* bad) when the main culprit is using a FF heavy beast for an APS-C zoom.

Sure, but it's an implicit admission of the possibility that it doesn't work 100% right. The dock just adds more tools to address it.

Don't we have AF fine adjustment precisely because of that?

The non-IS version is from 1999 and massively popular so the R&D cost has been paid for a long time ago (presumably, at least). Around $1000-1100 seems about right for MSRP.

Since those lenses all have stabilization, is it reasonable to assume the Pentax would be ~50 g lighter? Then again, the 70-200/2.8 is heavier than anyone else's...

The Canon is stabilized at 780 g as well.

Don't be silly, they said APS-C. 7000€ is enough!

Considering the size and price of similar offerings from other OEMs, less than ~3000€ for such a lens might be wishful thinking, if it's a no-holds-barred star lens with amazing performance.

The Canon 70-200/4L is 705g (and is great from wide open, with a great construction). My Tokina 70-210/4.5 is also pretty good optically, weighs 640 g and has 55 mm filter threads*. I assume Pentax can manage a sub-700 g lens with great performance.
*And similar to your F lens, focuses fast, loud and proud. The other day I hit minimum distance (worst part of the lens by far at 1.5 m) and the THUNK was so loud I thought I would *literally* shoot the subject in the head... Oops.

For all the yadda yadda about Pentax AF being slow and unreliable, AF-S with my Tamron 90/2.5 is pretty darn fast for a macro lens with a 200º focus throw. It's also very accurate unless shooting wide open with the subject further than... let's say ~10 m away in low light (it was a concert); I assume the difference between "5 meters" and "infinity" is too small to allow for accurate focusing. Can't comment on AF-C, I never use it :o

If the DC motor on the D FA 28-105 is the same as in the 18-135, then it's certainly "fast" and silent, but it doesn't come near the speed that the PLM shows on the videos.

The point of a 70-200/4 is not to outperform a 2.8 version (although it will probably be about as good for any reasonable metric), it's to be less than half the weight. If you think 1.4 kg is light then I envy your fitness :lol:

But those statements aren't mutually exclusive. They should, certainly. But very often, they are clearly not.

Well, in the case of Canon their slower L lenses certainly have the quality down pat. The 24-70/4 is still pretty chunky (600 g vs the 800 of the 2.8 cousin), but on the other hand it doubles as a macro lens.

Hmmm. 70-300 is roughly 4.3x. Maybe the entry-level tele?

To be fair, if you shoot at f/4, DOF is deep enough to get the subject nicely "there" without the AF struggling a lot. Also, lots of birders get perfectly sharp images with glass that is close to the limit of the AF sensor.
EDIT: just saw the addition (great picture! Was it a medieval reenactment?). I think we were talking about decent light settings here: I and some others have been expressed desire for the 70-200/4 precisely for outdoors photography, where weight is very much important and you have more than enough light for the viewfinder.

Why would you say this? I had already convinced myself that my Tamron 90/2.5 was enough for those situations! I don't want my LBA to come back :lol::lol::lol:

Of course; I think the change happened around the late 80s or more likely early 90s... AutoCAD appeared in 1989 (I still have AutoCAD 14 ingrained in my muscle memory, whenever I get a fresh install of a new version, the first thing I do is go back to the oldest interface possible, away with those useless "ribbons"!). From the samples I've seen, the FA* lenses should definitely be more than "good enough" for most people.

Zoom lenses have improved dramatically since the advent of digital cameras. CAD tools for lens designing make the complexity of designing a good zoom less much easier to handle without severe compromises. Heck, I upgraded my old, manual Tokina RMC II 80-200/4 (late 70s) to the Tokina 70-210/4.5 AF (early 90s) and it's already night and day. The AF one is sharper, has slightly better contrast and actually works wide open without blooming lights all over the frame :D. Stop them down to f/8 and there's not *that* much difference, but I still prefer the AF...
Primes, however? Hah, the Pentax-M 135/3.5 doesn't falter, and neither does the M50/1.7. Those simpler formulas might not correct everything and have incredible corner sharpness wide open, but they pack a punch in center-to-near-edges sharpness, have great contrast and lovely rendering. Not to mention having a pocket-fitting, 270g, relatively fast 135mm tele for when you need that bit of extra reach and speed beyond the DFA 28-105...

Knowing about the general state of any field (photography, in this case) is kind of a basic prerequisite to understand pricing and market trends. What other brands do gives an important comparison point.
Anyway, talking about the system at hand: in the case of Pentax, it's very simple and Ricoh's logic is sound in case you want a K-1: if you are willing to pay $2000 for a camera body, chances are you fit in one of two different sectors:
A) The Vintage Enthusiast. Someone who got the K-1 for their older lenses in order to give them a properly-sized sensor. This person does not care so much about FPS, top level glass or, more importantly, "beginner level" FF lenses because they already have their good quality vintage glass.
B) The Most Seriousest Pro-tographer (I kid, I kid. Those go for the 645Z. Seriously, I'm joking.): the type of person who wants ultimate IQ and performance. The type of person who gets the holy trinity of f/2.8 zooms ASAP, plus longs for the D FA* 85/1.4 for those buttery-smooth, short-tele portrait blurs. This person does not care about "beginner level" FF glass because it's not good enough for their needs.
While there are some of us who would prefer mid-range, modern D FA lenses with newer coatings, WR and budget-friendly price, we are most probably in the minority. Maybe we should have stayed with APS-C cameras? Maybe. But I'm very happy with the images my K-1 gets with the DFA 28-105 or my lovely Pentax-M primes. My Tokina 70-210/4.5 might be screwdrive AF and clearly outta the early 90s, but it's fast (both AF and aperture, hah), sharp, contrasty, and weighs barely over 600 g, so I can not only survive, but enjoy photography.

I sure would like it if the 15 and 70mm Limited covered the 35mm image circle, I'd have great small options for a very reasonable price :D

So, you want modern-design lenses that are well built, WR, have fast & quiet AF and don't cost a lot.
Mind giving some examples of such offerings from other companies? Asking for a friend :D;). As other people mentioned, the HD D FA 28-105 mm f/3.5-5.6 DC WR is your best shot. Works wonders, I think.

That's why I'm saying that I have no clue whether the new SDM ring-type is better than the DC motor in the 70-200/2.8 and 150-450 long teles. The teles have a "worse", in principle, motor, but they seem to perform decently well.
About the PLM, I'm afraid that the focus-by-wire is more or less a necessity of a linear motor. The 55-300 WR is still in production however, so hopefully Pentax takes a long time to phase the alternatives out.

I know, this is what I said. My point is that the name does not necessarily mean anything substantial. And yes, obviously everything in the camera is DC, that's why calling a motor "Direct Current Motor" means between zero and nothing by itself.

The thing is that "DC" and "SDM" are basically marketing names mixed with technobabble. Both are "direct current" motors, by definition.
