FWIW, I just posted a webpage showing some sample photos I took
yesterday in Boca Raton using several older Pentax manual focus
telephoto lenses:
SMCA70-210/4
SMCA*300/4
SMCK85-210/3.5
SMCK200/2.5
If interested, you can take a peek at:

Took this one today as a candid but it
ended up looking posed:

image has lots of cropping and processing,
not really a photograph anymore with all
the stuff I did to it.

wouldnt an EVF camera eat batteries even worse than flash?
I dont like the fact that it consumes energy while an optical finder
doesnt.
Battery life wasn't a problem with my Olympus C-2100 UZ. The low
resolution screen in the EVF wasn't stellar
If you took any pix of exact same subject and lighting and aperture and
focal length
with both we would love to see them.

ideally, really good zoom lenses dont change focus when zoomed in or
out. I guess this
is a separate issue from AF focus errors vs focal length. I still dont
understand
why these pentax cameras dont auto focus all the lenses the same when
the
af sensing is in the body. The AF bodies need
why not make up some simple stick on address type labels and put them on
the back of
the photos :

these labels are cheap and may save some headaches in some cases.
I can see using f32 for macro dof issues, but the lens is
sharper in the f8-f11 range

would be even happier if DA*60-250/4 would
be less pricey (it's 1550 USD in here and our salaries are not
comparable to US or Western European ones), but I still feel that
money well spent..

are intended for digital APS use. See Ned
Brunell's recent column ad the listing for the DA* 60-250 on the
Pentax USA website. The fact that you can use a lens as a hammer
doesn't make it a good hammer.

thats interesting, isnt DA for aps
Um no, there are lots of lenses without any visibly noticable light
falloff
on the edges of the intended format, mostly long ones.
I would not agree with the statement that all lenses could be considered
optimized for APS-C just because they dont have as much light falloff
or corner sharpness
If I get the time and remember, I will take my A70-210 out
to Boca Inlet and get some seascapes with it and some similar
primes and zooms for comparison. I aint be able to shoot
the DA60-250 because theres no way Im buying that at $1350
now. From what I recall my Tamron SP 80-200/2.8 is at the
top
well, pentax has been doing med format since
1970, and ultra high quality FF digital would be nearly he same thing
as med format in todays PS marketplace.

the untold problem with doing hd video with still camera lenses
is that the zoom lenses you can get are not well suited for video
use, no power zoom, no proportional power zoom. It might be fun
once in a while to do HD but it wouldnt be fun full time with
typcial SLR camera lens zooms.

I got curious and went out in the parking lot
and snapped this one today handheld with the A70-210mm/4 on digital
(istDS).
I think I was around 180mm and F8 on this.

Not a critial test but based on this and some others I shot, I can see
no flaring
