Leon, I know that. But such a thing would defeat the purpose of Live 
View which IMO is to show me the subject on the camera screen all the 
time. Anyway, I don't think that I will be using the Live View all too 
often, and my remark was more of an observation.


In fact, I reckon that the 3rd (and hopefully final) part of the review 
will have positive summary, as I seem to have worked through most of my 
learning curve now.

It removes the live view image for a split second, but it's a lot

When I got the K10D, I read those warnings, and I went out and did some 
tests.  SR helped even with the panning shots, and even with panning 
shots done from the monopod, so I leave it on all the time.  I may cause 
issues in some situations, but not in the ones for which I use the 
camera.  Since I mostly shoot race cars on track, something above 50% of 
my photos are panned.

Read carefully Peter. The note on page 308 is a troubleshooting guide  
that tells you what to do if shake reduction doesn't work. It says  
that when panning or shooting at night with slow shutter speeds, it  
may not work. In other words, SR won't eliminate shake in a slow  
shutter pan. I already know that. But there's no need to turn it off  
when shooting a slow shutter pan. I know that, because I do it. And

Re: Boris reviews Pentax K-7 (part 2)

2009-08-27 Thread P. J. Alling
To everyone who thinks the Pentax has decided that SR can be left on 
while panning, perhaps they should update their documentation.


Page two on this PDF hosted at the Pentaximaging.com site

http://www.pentaximaging.com/pdf/All_Bodies_Shake_Reduction_012208.pdf

or the K-7 manual on page 310 of the K-7 manual

http://www.pentaximaging.com/pdf/K-7_e_web.pdf

or the K20D manual on page 267

http://www.pentaximaging.com/files/scms_docs//K20D_Manual.pdf

I'll leave it as an exercise for the student to check out the manuals 
for the K10D, K100D, K200D and K2000/K-m.  But I'll wager they all say 
it's best to turn off SR while panning, as well as while using a tripod, 
taking macros, etc. 

I think I'll take the word of the Pentax engineers and marketing folks 
that SR should be turned off, I tried a couple of panned shots of flying 
birds and they came out looking double exposed.  I deleted them but I'm 
sure I'll forget to turn SR off again, and I'll post some samples.

weren't complaining, they relegated the switch function to a less

I shot from a 30-foot high scissors lift with the K7 and a modest  
tripod (a Slik carbon fiber). The lift wasn't perfectly still, but I  
would wait to release the shutter until I couldn't sense any movement.  
Shake reduction was on, and I experienced no problems.

I've never needed to turn the shake reduction off in the K20D.  If I
have the camera on a tripod on a really solid substrate -- bedrock,
concrete footings -- I don't get any benefit from it, but I haven't seen
any harm from it, either.  Never tried to shoot fast motorsports, but
panning to follow flying ducks (~60 mph) doesn't seem to trouble the shake
reduction algorithm any.

On the other hand, I've had it turn off by accident and regretted that.

I suspect deleting the SR switch in the K-7 is an acknowledgement that
it's not something you need to turn off very often, and that those
occasions where you do turn it off are also those where you're just not
in a hurry; the substantial tripod and the really solid substrate don't
admit of being in a hurry.

Re: Boris reviews Pentax K-7 (part 2)

2009-08-27 Thread John Francis

When I got my K10D I conducted a few experiments, and found that
leaving SR enabled while panning was at the worst harmless, and
in fact probably helped to smooth out irregularities in the pan.
Since then the only time I've turned SR off is when shooting on
a tripod (and then only if I remember :-)

The physics of the system supports that position, too. The SR
system is based on accelerometers.  On a smooth hand-held pan
(rotating the entire photographer+camera system round a fixed
point behind the plane of the sensor, but on the lens axis)
there is no acceleration in the plane of the sensor, and so SR
will do nothing except smooth out the panning motion.

The only inconvenience I've noticed abut the new strap is that it tends
to get a lot more often into the way if the camera is on a tripod,
especially in portrait orientation, than it did with the sideways
attachments of the earlier models.

Other than that no probs with it. As far as the vulnerability of the
powder coating on the camera body goes, I'm keeping my fingers crossed
that there was something wrong with the coating on my first K-7.

In shooting mode, push the INFO button and you have several controls 
available there, including SR on/off. Not as direct as a hardware switch, 
but not far from it. Much better than navigating the ever-increasing 
menus.


I forgot to mention that I've disabled the status screen, in order to 
prevent it from drying the battery for the sake of tanning my face and 
dazzling my eyes. Another side advantage is that the status screen never 
comes in between, and pushing INFO goes straight to that useful setting 
palette (instead of repeating info I alkeady know by the viewfinder and top 
panel).

The SR switch is a shooting control. Maybe not as important as manual 
control of the focus point, but until Pentax comes up with an SR system 
that's smart enough to know when the photographer is panning, turning it 
off at a moments notice will be a necessity .
Removing the switch and making it a small production to turn SR on and off 
shows what I think is a "Point and Shoot" design mentality the same thing 
that resulted in the focus control debacle, This type of mentality doesn't 
belong in the design of a relatively high end camera, hell, it doesn't 
belong in the design of Point an Shoot camera.


Unlike the focus point issue it looks like it's not an easy a fix, what 
with the hardware switch being gone and all...

Unfortunately, the K20D is even more crippled in long-time exposure than
the K-7 with firmware 1.01.

This is why I've sold my K20D and kept the K10D. 

BTW, I'm looking for a used *istDS. Mine is developing some sort of
galloping dementia and I still want to keep one for infrared.

I second that. Pentax have made a terrible mess of their formerly
excellent customer service, so a second body to keep you going while
your main camera is away for repair much longer than what we all were
used to seems like a good idea.

Besides, the K10D is Pentax' last camera that's fully usable for
photographing lightining, fireworks, astro or other long-time  
exposures
without having the camera blocked half of the time while it's doing  
its

dark frame.

I've kept mine. Not lastly because there's a marked increase of used
K20D on the market now and prices for the K10D are so low that it
doesn't make sense to sell them.

I had a problem with this when the "viral tour" came through

If I end up getting the K7, I'd probably best sell the K10D.  I'm not 
sure I'd ever be able to train my brain to flip back and forth between 
the two cameras and get all the buttons right!
