Why do people voicing such strong opinions know so little? The DA15 and DA21 have always had 7 aperture blades, and the new versions still do, as they should. The 14 point starbursts they produce are fabulous and stand them apart from the overly-busy 9 blade ho-humness of just about every other premium lens.

All the other haters can go jump. This is great news; Ricoh/Pentax are committed to continuing the DA limited legacy and these announcements (along with the *awesome* news about two new WR flashes) is no doubt the tip of the iceberg.
but sandy it clearly states that the 15mm will be upgraded to 9 blades. hmmmm I don't know where to check.

About the designation... Since years the term "HD" has stood for 720p, and "Full HD" has stood for 1024p. I have no idea what its doing in a lens coating designation. A bit like saying the tires of my car have 120 horsepower. The horsepowers is not an attribute of my tires.

Even a term like Ultra Multi Coated, would have sounded less cheesy.
I fully agree with this.

Calling a coating "HD" is almost as annoying as when someone talks about how many Mbit/s the "bandwidth" of his Internet connection is .....

I smell replacement on the way then. It makes sense to me. Upgrade the current lenses to handle higher resolution sensors, then release new ones along with new cameras. If the LX-D is in fact true, it might be using the 36 MP FF sensor as that sensor has shown that it could out resolve the current generation of Nikon lenses and coating. And what did Pentax just do? Update lenses with "HD" coating.

P.s. I think the FA limiteds will be getting the HD and WR treatment. Why not the DA's? Well size is a big factor. Adding weather seals to tight tolerance lenses is not an issue, but it would require more space, thus breaking with the DA limited design philosophy. The FA limiteds are lenses that are designed to be the pinnacle of resolution and light handling/gathering with emphasis on IQ. Size is not a constraint with FA's so I think we can expect them to have WR sealing. Just my .02.
Seems like the DFA 100 WR isn't any bigger due to the seals. Not sure what exactly it entails -- a gasket at the base and some seal internally, but I wouldn't think it would be that hard to do.

Not a suppository in sight either ;-)

May I suggest you go back a few posts and read the table in the press release from Ricoh Japan (in English):

I fully disagree with this. HD is an acronym which can mean anything (Horse Dung, anyone?), while horsepower is quite specific.

Very large and heavy for a pancake. For AF on a screw drive it would be S...L...O...W

The OOF isolation difference aesthetically is mere inches.

If they already have an awesome product and want to make small worthy updates to it, that is all good I think.

My my, this place is so negative.

Yesterday I was telling a friend of mine (a longtime Canon user) about all the primes that Pentax has available, and other lens in general, and he was pretty impressed. Even though Canon has twice as many lens available, primes is what he likes and he didn't know Pentax has all that good stuff for very reasonable prices (compared to Canikon especially).

Also, people are forgetting that it's not just the HD coating (if they have that coating process, why not upgrade the Limiteds to it?), but also the rounded blades. That should help the bokeh of every lens, perhaps even sharpness. This is not a minor thing.

But I understand this place is more concerned about novelty and being sometimes more excited about new gear rather than taking pictures in the real world, so the negativity is kind of expected. I understand that people that do demanding photo work will appreciate what Pentax is doing. As we say in Brazil, 'if the team is winning you don't mess with its game'. Pentax primes are awesome and if this is a sign that Ricoh is committed to them in the longer term, then I'm very happy about these news.
+1 Already had my dummy spit along the same lines earlier today commenting on Adam's announcement of these lenses. A

What really irks me is the marketing for "High Definition" audio, when the term specifically refers to video applications. The correct term for audio is "High Fidelity," although I guess the marketing droids thought that would sound too old-fashioned.

Sure. Just like MPH, which really is an acronym which can mean "My Pretty Horse", cm is an acronym which really can mean "can meet", RADAR really is an acronym which can mean "Rapidly Approaching Date Assault-Rape" (and not "Radio Assisted Detection And Ranging"), and XRAY really is an acronym which can mean "Xenophobic, Racially Androgynous Youth"....

Yeah, you can redefine anything to mean anything. But that doesn't make any sense.
If you redefine a term that already has a well-established semantics, then that just creates confusion and imprecision.

So, Sandy Hancock, I respectfully suggest that you're right - where, of course, I redefine "right" as an acronym to really mean "really incorrect, genuinely, honestly, truly"

I'm not saying new coatings won't lead to better overall images, simpy that resolution is a specific technical term, and coatings won't magically help an optical design that can't resolve at a single photosite level on a given sensor to do so.

As an opposite example, I recently picked up a Spiratone 185mm f/1.8 it is a 40 year old Sigma design with correspondingly primitive multicoating. When used correctly, it EASILY outresolves my K-5 sensor. However, compared to modern lenses, the contrast isn't as good, and it is prone to flare when shooting toward bright light. A newer coating would improve those aspects, but would not do anything to improve the overall sharpness of the lens (i.e. the resolution).


QuoteOriginally posted by theperception2008 Quote
But doesn't the improvements to flare, reflectivity and increased contrast lead to improvements in resolution as well as optical design? Weren't the Mark I DA limiteds fine with the 16 MP Exmor processor? Why change the coating if the sensors are't going to benefit from it?

Proper naming of stuff is gone I am afraid. Long gone. Years ago I drove the sister-in-law's Toyota Corolla with an SR 'Super Responsive' motor. Had to overtake multiple large trucks in the dark on an unfamiliar narrow and winding road. The total absence of any responsiveness was frightening. I still remember that drive nearly 30 years later.

And I'm old enough to remember all that peak music power crap that was used to flog ghetto blasters in the 80's.

The real problem for manufacturers now is to find a term or abbreviation that hasn't already been trademarked and usurped by someone else.

Actually, MPH and cm are not acronyms - they're abbreviations. RADAR on the other hand IS an acronym! (just trying to lighten things up)

Let's not confuse this discussion with actual facts of things, and let's focus on the important issues here; the lenses tap the 'Pentax' red color scheme - how were they ever green in the first place? Heads need to roll. And the lighting setup on the new product shots seem to have reflectors set up to the family of angles to produce direct reflection. What's the significance of that to the overall approachibility of the item in question; top-heavy old green versus top light pentax red. How is this newfound consistency and/or intelligence being trumped by semantics of HD in this thread.

Oh dear...

Let's see hat Merriam-Webster has to say.

acronym: "a word (as NATO, radar, or snafu) formed from the initial letter or letters of each of the successive parts or major parts of a compound term"

abbreviation: "a shortened form of a written word or phrase used in place of the whole <amt is an abbreviation for amount>"

MPH == Miles Per Hour
CM = Centimeter

I might concede that CM could be an abbreviation (although, I'd be ready to debate that......), but MPH most certainly is an acronym
