Kevin,
>From an 8.5x11 inch Pentax Lens catalogue, page 26 covers SMC-A Rear
Converters. The table Usable Lenses with Rear Converter-A says the A*300/2.8
can use all 4 converters (1.4 or 2.0, S or L), but it indicated Better
performance can be achieved with the L versions on the A*300/2.8.
If I look at the table, the L versions are for BIG glass. They indicate
better performance with the A*300/2.8, A*400/2.8, F*600/4, A*600/5.6, and are
the only ones recommended for the A*1200/8, F*250-600/5.6, and
FA*250-600/5.6. The only exceptions I can see are the A200/4 Macro and
85/2.2 Soft Focus, where the L converters are marked as usable, but not
marked as Better performance...
That's as close to an official word as I have seen published.

I was wanting to put a 2x-L on my A*300/2.8 until I checked Boz's site which
says the L converters are for focal lengths greater than 300 mm. Can I or
can I not use the 1.4x-L and 2.0x-L on my A*300/2.8?
