More on FF'ing

Hmm, not sure I can confirm the reflection theory - it is doing it in other scenes too - in fact I just tried a shot from my balcony and focused on another balcony at f2 and yes - its soft and FF is visible so this isnt necessarrily only in indoor low-lighting either - its almost in all low-light situations as it just happened outdoors too. I am 99% certain it will be fine tomorrow during the day at f2 with the FA50mm - I will test that tomorrow too and see if there is any FF visible - but Im seriously doubting there is - will update on that issue tomorrow during the day.

Bill - exactly what happened to me yesterday - it was utterly
useless with the battery being close to depleted - which I didnt
know about since the battery indicator is terrible and was still
showing a full charge when I started testing but then shortly after
went down very quick and hence the completely unacceptable results.
But unfortunately - I am sure mine is still FF'ing in some cases at
fast apertures (ie. f2) even with the battery fully charged. I have
a theory that maybe if you notice all the scenes with FF have some
sort of glass that is reflecting light a little and the 2 examples
that I posted that dont have FF dont have any glass that is
reflecting anything! I wonder if the bottle or the, metal shiny
base plate of the lamp, the slihgt reflection off my photo frame
on the wall etc. are putting the AF off. Because with non
reflecting subjects in low-light it did do better - I will keep
testing this actually - maybe the Pentax AF is just more easily
fooled by such things? But I just noticed it and maybe it has
something to do with it? I will post back if this theory holds any

The LTD 77 is indeed the only lens I use in incandescent light.
However, I had completely forgotten that I did encounter severe SR
and focusing problems when the battery went way down. The battery
lasted so long that I simply forgot that it hadn't been charged,
and it actually stopped working altogether shortly after I was
puzzling over the SR problems focusing problems.

I concluded that this was normal when the battery was low and
resolved to get a second battery and simply not ever work with the
battery below about 250 shots.

I put this out of my mind after making this decision, and didn't
think about it when I made my earlier post about no focusing
problems and in incandescent light.

I certainly have had none since resolving not to work with a low

This is a minor nuisance but I'm afraid that if one is going to use
the K10D with all the other great features plus the inexpensive
stabilized lenses there are just some feature peculiarities that
one is going to have to accept as the price of saving money.

I love the K10D BUT if I had $1 million to spend on my photographic
equipment I would have no hesitation about switching to Canon --
the sensors are the best in the world and their lens selection is,
I feel, the best. The one exception is that of course they have no
stabilized fast primes.
