Hi Jim,
Any detail about the new Limited lens FA23/F1.9?
Thanks a lot.

Really? I thought the next Limited was an 18/2.8. Hmm..this is going to be expensive.

Interesting, the same magnification factor between 23 mm and
28 mm, as 31 & 35, 43 & 50, and 77 & 90.  Four lenses?  You

Shel, find yourself an FA* 24mm f2.0 and give it a whirl.  It'll most
certainly change your mind.

The other reason I have to doubt the rumor is that the FA* 24mm f2.0 is
a really freakin' huge chunk of glass...a 23mm f1.8 would have to be
even bigger, and that seems to me to go against the Limited grain.

I don't buy it.  First, I don't think Pentax has ever made a 90mm lens for
35mm, and secondly 23mm F1.9 is way too close to the FA* 24mm F2, both in
focal length and maximum aperture.  I'm guessing the next one will probably
be a mid-tele, something 120-150mm.

Hi Tom,

The FA 43mm LTD was released in Japan with Leica screw mount and a 
flash shoe mounted finder. Since the mounting flange to film plane is 
distance on the Leica (range-finders) is much less than the Pentax SLR 
there is no need for optical convertors, the lens simply has to be placed a 
little further forward of the Leica mount. I don't know if the Pentax lens in 
Leica screw mount provided for range-finder coupling either, this would 
significantly reduce its appeal to all but die-hard fans as scale focus would 
be the only option. I haven't heard any news of the other Ltd lenses being 
available in screw.

Cool. How many mm?

If it helps, don't think of it as "a spider". Think of it as "a fabulously
engineered, autonomous, self-replicating, AI, bio-tech pest control
device". So expensive even Bill Gates couldn't have one built for himself
even if he blew his entire wad--and yet, you get 'em free.

The only bad thing about the spiders in our house is they don't sweep up
their "empties" (rollypolies making a wrong turn at the screen door,
mostly, occassionally each other). 

They come in the standard black and grey Pentax colors, too. Gotta have 'em.

Re: Clue re next limited lens

2001-05-22 Thread Grigolia

 If we're going to bet on the new Limited wide-angle lens I'd bet on 22mm.
 If Pentax is consistent, the 43mm lens was midway between 50mm & 35mm.  
The 31mm was midway between 35mm & 28mm.  A 22mm lens would fall midway 
between 24mm & 20mm lens offerings.
 For a medium telephoto I'd predict a 110mm lens.  Which would probably 
be followed by 175mm & 250mm telephoto lenses.
 And I still think if there is a 18mm lens in the near future it will be 
an FA* lens.  An 18mm f/2.8 is a pretty standard ultra-wide-angle lens 
offering!

I don't see Pentax trying to compete with Lieca with the limined lenses, it
seems more like they are building lenses for a niche market other SLRs
makers are mostly ignoring.  And if they wanted to compete with Lieca why
not release 50mm, 90mm, instead of focal lengths 1.2x off?  

And are you talking about Leica SLRs or rangefinders for this adaptor?  I
would think an adaptor to the rangefinders would be nearly useless, as
there would be no linkages to the focus aids in the viewfinder, leaving
just the distance scale to focus with.  Plus a large SLR lens would
probably block the viewfinder.  So that leaves Leica SLRs.  Anyway such an
adaptor would take away part of the uniqueness of these lenses - the odd
focal lengths.

I meant 120-150mm, as in a range of focal lengths.  There were even rumors
of something like a 124mm Macro a while back.

Better built, definently.  But a 23mm Limited lens can not be much smaller
than the FA 24mm unless they choose something slower than a F1.8 or F1.9
opening.  Fast lenses need big glass, and you aren't going to be able to
cram a 23mm F1.9 lens into a small package.  On the other hand I called
Pentax nuts for making the 43mm F1.9 limited, as it would compete too
closely with the cheaper and faster 50mm lenses, but I was wrong.

Well Bill, 
Since someone here on the list said he actually knows
someone who got to use the 23mm for a week, I would guess
there is at least a prototype in existance. Me? At this
point I would be suprised to see a limited that did not
maintain that 1.2x ratio. But, of course, my actual
knowledge of what Pentax is doing is about the same as most
other members on the list, pure speculation, so you have as
much of a chance as I do of being right.

31mm = 1.107x (from 28mm)
43mm = 1.229x (from 35mm)
77mm = 0.906x (from 85mm)

A 1.2x ratio taken from 28mm, 35mm and 85mm lenses would give focal
lengths of 34mm, 42mm and 102mm respectively (or would be taken from
lenses with focal lengths of 26mm, 36mm and 64mm respectively), so I'm not
sure where you took that number from, unless it's derived from the 43mm
Limited ratio.
