Athough better late than never, I just got my first SMC PENTAX-A*
lens today, the A* 300mm F4.0. I cant believe the small size in
length,
If it's half as good as the F* 300/4.5 it's an awesome lens.
Congratulations.

I collect and use, first it was the complete set of smc takumars, now
I am working on a complete set of the first K series, plus
assorted good M A series lenses but not the whole set of M A,
the K are nicer in many instances.

Hi,
For the first time ever, I would like to get
a 24x36 color enlargement made from an
assembly of 6 Mp digital images into one large
digital image file. Anybody have any
recommendations for a mail order/online
lab for this service??? What are the options
in terms of archival quality usually?
hi yall,
I have been very interested for a long time but not finding any NEW price
information
on all NEW Pentax lenses made since the spotmatic (1964) era. I have
found a few NEW list prices for a few years here and there but no
NEW street prices for the older lenses. I would be very interested
what that means is you dont have a true zoom lens most likely,
something must be changing that shouldnt.

the A24-50 is a steal for $80 in good condtion, if Pentax
ever goes FF you will have a really valuable lens on your
hand, even now, its a nice range on digital SLR.

I really like the Pentax Straps made of nylon that are about 3/4 wide at the
shoulder
and are black with PENTAX in red leather. They are soft and comfortable but
not too
bulky. I have been using them for about 20 years...

Correction, black with red L E T T E R I N G, not leather.

Did
that the mechanics of the
A24-50 is very good and that it is smaller than DA*16-50.

that's good to know but are you talking much sharper
at F11-F22? I cant see how there would be a big
difference in that range, the A24-50 is really good
I would get a good 28mm prime. The sma-A F2.8 is
nice if you like manual focus, the later F and FA
versions would do if you want AF. But in any case
a 28mm prime is very useful/high quality on DSLR.

this summer. I´ve had it since the mid
80s and it has been great with film, but compared to my primes in that
range it wasn´t not sharp enough for my use on K10D. My DA*16-50 is
much better.

Did you have the A version or the F
of the sensor/lens
combo and giving up quality. Unless DoF is an issue, there's no good reason
to stop down past f11 on 1.5x crop digital. The 16-50 will outperform the
24-50 at apertures where diffraction limits are not an issue.

that's good
yep, great lens. I cherish mine along with all the other K series lenses
I have luckily managed to acquire so far. The K85/1.8 and the K200/2.5 are
two of my fav telephotos in K mount. The K105/2.8 K120/2.8 and K135/2.5
ain't too shabby either. The original SMC K Lens series definitely RULES!
