I've always assumed that the "L" stood for "long" TC and the "S" for
"short" TC, rather than referring to the focal lengths of the lenses
to be attached. (How

Me thinks you`re not using the right stuff. Last weekend I used my
1000/8 SMCT with a full set of Asahi extension tubes, a Vivitar 2X
Macro Teleconverter and an LX on a Bogen 3051 with a 501 video
head and got a close up of an owls face, you can see every feather

Pentax made a 2X-L converter dedicated to the longer A* series ED lenses.
It works OK with these lenses. Otherwise, no non-dedicated 2X converter
gives great results

The best Pentax TC's for long lenses (but only for lenses that can
fit their "snouts" into the K-mount end of the lens) are the "L"
models (A 1.4X-L and A 2X-L). I don't know

Absolutely. Such a setup has really limited uses, I'd imagine. Filling the

Jan,
You've answered a question of mine before I've even asked it-
I was always wondering what the differences were between the -S
and the -L convertors. Thanks.
The "snout" to which you refer- is that cause for incompatibility
with certain lenses of a more conventional focal length, like a 80-20

I just dug out the Pentax user manual for the Rear Converter A's,
JCO, and it seems that:
1. The A 2X-S should work OK on the K 1000/8.
2. The A 1.4X-S will show some corne

I think the 'best' one quality wise would be the "rear converter-A 2X-L"
This is a large (over 2 inches l
Yes, it will be a 2000mm F16!

That raises a quick question...
Is there a limit to the usage of a teleconvertor? Wouldn't putting a 2x tc
on a 1000mm making it very slow?

I read somewhere (dont remember where) that 7 element converters are
much better than 4 element ones (or was it the other way round ? :))
I guess thats not much of a help :D
