The Pro version is supposed to work with all RAW files.
With the standard version if you save RAW+JPG it just
uploads the JPG and you can copy the RAW files from the
card later via a USB Reader. It doesn't have to be the
Reader supplied with the card.

Mines just the basic 4GB Jpeg only one, but it's still great

There's no problem using more than one PC either. I just put the
card and SD reader on a 2nd PC and installed the latest software
from the Eye_Fi site. It found the card (probably didn't need to
put it on the PC) and asked me which of the two PC's I wanted to
upload to I assume that I will be able to chose which one
if I go into manager.

Pity I can't upload to two PC's at once? Does anyone know of any
software that will watch a folder and then automatically send any
files to another PC over the WiFi? I suppose backup programs will
do it? At present I just drag the files across in Explorer.

I've been using it this afternoon with a laptop in the kitchen
trying to sort out the focusing on the K-5 with MF lenses and
it was great seeing each shot on the screen as it was taken
Still didn't sort it out even Live View isn't accurate enough
I'll have to try again tomorrow and see what focus aids work
in LV.

Much safer than tethering as well I have a USB mouse radio dongle on
a short lead and when I finished I closed and moved the laptop
without unplugging it If that had been connected to the
camera.... the camera and tripod would have gone over

There's a list somewhere of what lenses work with Canon's.
Ricehigh also has some Pentax/Canon info.

If he asked me could he have a chip..... I'd give him
my FISH as well!

Great shot Don.... looks like it's only just caught it

£210 for a 180mm f/2.8 sounds like a bargain as long as it
will produce good results. It should do because they had a
cheaper f/5.6 version.

For many years Sony DV cameras have had a Touch Screen Point to set
focus to that point and the points aren't fixed they can be anywhere
on the screen

Canon were supposed to have a system where the focus point moved to where your eye was looking.

I've never used anything other than centre focus and doubt if I ever will use anything else..... it's not that accurate anyway

My K-5 and Sigma 10-20mm seem to have been devalued

That's correct about 1:1. It can be confusing, because if you
were photographing a 36mm long bug on 35mm you would not need
1:1 on the APS-C to fill the frame with it.

Some info on IF lens FL's here link

This suggests that the FL of a 180mm IF lens at 1:1 is 107mm
So the 180mm isn't such a big advantage.
