I don't think you need to switch SR of in those situations.
TC makes SR less effective, but it still does a rather good job.
I haven't tested it out really, but this is what my instincts tells me.

With the M2004 and the A2X-S converter you can dial in 400mm shake
reduction when you turn the camera on. I have dialed in 800mm (the
max) when using the A400/5.6 with the A2X-S
Hi
I've had less than favourable results myself, I found it better to switch off
and find some way of steadying the lens.

For Pentax autofocus to work the TC's have to have to transmit the FL.
The TC's in fact simply pass data on the digital pin straight from the
camera to the lens and vice versa. To do other wise would require the
TC to make changes to the data stream, and frankly I don't think they're

Hi Patrick
Yes it's a great lens by all accounts, I was considering A Sigma 400/5.6 APO
Tele Macro (s/h) and 1.4x 2x EX converters but I'm back to my SR problems
with converters. I'm thinking of forgetting the SR problem and getting myself
a lighter tripod to carry, then whenever I need to use
One other combo you might want to look at is the 100-300 f/4 + 1.4x tc
That gets you to 420mm at 5.6 and the 100-300 is very highly
regarded.. The only downside of that is that the K10D does not seem
to be aware that a TC is in use and hence the SR system's performance
is not as good as it should
I have the bigma and ...
1. Does SR work effectively?
Yes but not as effectively as at the short end.. I estimate the
effectiveness at the long end (above 300mm) to be around 1 - 1 1/2
stops.
2. Is the lens type displayed correctly in the EXIF i.e. Sigma 50-500 EX?
No ACR just says sigma
Hi Patrick
Thanks for the reply, very much appreciated. I think the only thing putting
me off is the lens extending when zoomed, it's the main reason why I sold
the 135-400 I had. Having said that it does keep the size down when
transporting the lens in a camera bag.
One last question, if I

They aren't binding at all. I expect they're just put on for
intimidation factor (though I don't know who'd be intimidated).
