This chart showed me a difference between the 40Ltd & 40XS that I was unaware of previously. The XS has SP coating while the Ltd does not.

Alternate interpretation: FA Ltds are discontinued???

I have no idea if this is or not true. But the three amigos (FA31, FA43, F77) will become even more "most wanted" if they become discontinued, because these 3 lenses are legacy lenses.

Some great reads on these FA Ltd lenses include:

All the cheap primes, 40xs, 35 and 50mm are tagged as having quick shift.
I wonder if this is a real Pentax document...

- So FA Limited are officially removed now?
- No more DA14/2.8?
- No point including any accessories that cannot be purchased outside Japan.

Hopefully they are distributing printed versions that don't look blurry and pixellated at the same time ! (like the PDF)

DA* 50-135: “An additional plus: the inner focusing design maintains the focusing point through the full zoom range.” (page 17)

Does this suggest that a single AF Fine Adjust setting, zero or otherwise, should suffice across the full zoom range? e.g., no need for different Fine Adjustment settings at the long and wide ends?

Craig, it's kind of a weird statement; all 'zoom' lenses by their very name name maintain the same focusing point throughout the zoom (i.e. if you are focused on a tree at 135mm and zoom out to 50mm the tree will still be what is in focus). Lenses that do not do this, in other words where the point of focus changes as they change FOV, are called 'varifocal' lenses. (What causes the need for AF adjustment is more complex and so simply being a zoom lens does not imply the latter, that a single AF adujst setting will work). Well, as is usual for such brochures, there is marketing speak like this (and the SDM being 'extremely fast and silent'; in fact nothing can be 'extremely silent', since silence implies no sound and you cannot have degrees of what is not).

No FA Ltd lenses. But a nice book.

the brochure isn't new in fact. it was made for the "Salon de la Photo" 2012, october, in Paris, France.

DA 15mm: No mention of mind control.

No. Wrong interpretation.

No.

Yeah, that is either a big mistake or not officially a Pentax brochure.

Basically, the brochure means nothing.

No.

Why? Because you say so without any presentation of facts or semi-intelligent thought? That's real convincing. Anyway, look up the meaning of "alternate" and "interpretation" and then learn what "wrong" means too.

Sadly, this useful verbal distinction seems to have become lost,
at least in general photographic language,
so now "zoom" in the strict sense you mention
has become "parfocal zoom."

With a classic still photography "zoom" lens, on film,
you used to be able to change the focal length during exposure,
creating a "zoom" effect.
Can this be done (without causing damage)
with the DA* 50 -135 on a modern DSLR?

I said so in a post before you posted yours. Its based on the only thing that one can base their predictions on - events that happened so far. Also, Im not saying alternatives are all wrong, but they certainly can be. I just didn't want this thread to spiral into another "Pentax is doomed" thread

It's in the photo on page 2, just not anywhere else.

Hmm, but on the "official" pentax webpage for the 40Ltd, the spec sheet (the "notes" line) says: "SP (Super Protect) coating"

PENTAX - smc PENTAX DA 40mm F2.8 Limited

Must be an oversight in this brochure, just as the brochure is wrong about QS for the 40xs, 35 and 50mm
