Brilliant idea Stefan, but you missed CF which is a bit strange because you remembered to include SD

And yes, CF is related to Pentax as it was used in the istD.

My Names Alan, and I'm a lensaholic.

Thank you all and I'll include them.
The wiki links need to wait though, don't think I can find time today, sorry.

I also forgot RTFM, any good ways to write that in a propper manner, the F word is a bit of a problem. Wel not a problem for me, if it was my choise I would write full out (it's just a word afterall) but don't want to offend anyone.
Problem solved

Um, a four letter acronym. Perhaps, but it's acronym would have to be FLA, which of course is a TLA and would conflict with the TLA for a five letter acronym.

I already had Read The F*** Manual - There are different version of this with various F-words but they all mean that you should read the manual.

I dleted it since it was an internet slang but it's photographic enough to be in the list though so will throw it back in.

Still need those of the Pentax point and shoot cams but I'm new and not from the film age so do someone know one I've missed from that age?

Now going to finish the list so far.

Would you believe the correct name for a four letter acronym is:
"An Extended Three Letter Acronym"...... True
