Since the OP is talking about "Professional Photographers", I don't
think "comparing 'standard' cheapies to standard cheapies" is
appropriate.
Actually, jvora said:
"Are SD Cards being catered more to Professional Photographers than
CF Cards - Is this a new trend ?"
-----------
To which I would say YES.
That says nothing about buying higher-grade flash memory,
specifically, but format type. More and more cameras are offering SD
(and CF is made in standard grades, too, just like SD). It may be a
bit faster with write speeds than SD Standard Grades, though...or it
may not, since some manufacturers don't list the speeds of their
cheaper product (Kingston, for example). Probably 'cause it looks
less-than-nice in advertising.
jvora also said:
"Upto now, I felt that SD Cards were more for consumers - is that
true or have "things" changed."
----------
I would say things are changing, but not totally there yet.
"Will we see more amd more pro-consumer and professional cameras with
SC slots instead of CF ??"
----------
I would guess it's inevitable.
Pricing:
-----------
A quick price check on B&H with search terms for Sandisk's cheapie
range: "Ultra II 4GB" and "Ultra II 8GB" and then sorted by price
resulted in SD being cheaper, both times. A search for "Ultra II
16GB" resulted in no matches for CF, so no comparison there with
Sandisk. If we try a search for "CF 16GB" and compare "SD 16GB" then
sort by price, SD wins again, with both cheapest items coming from
Kingston. So my statement holds true.
Same probably applies at Newegg, Adorama, etc. Don't know, haven't
checked, but SD is usually far cheaper in the shops here; computer
stores sell it (they sell almost no CF, assuming they stock it to
start with). The point is the volumes selling and the competition are
more active with SD.
For comparison, a similar search for higher-speed models from
Sandisk: "Extreme III 4GB" and "Extreme III 8GB" and "Extreme III
16GB" sorted by price, low to high, resulted in CF being cheaper by
varying degrees, biggest difference coming at the higher capacity.
That's just comparing Sandisk's Extreme III range, though. CF
probably still has its niche here, so less competition from SD, but I
reckon that will change as manufacturers increasingly look to
accommodate for a smaller slot and memory that people can find
anywhere. Plus I never claimed CF was cheaper in higher-speed grades,
but it was a nice exercise, because I expected CF to be overpriced
here too (it is quite overpriced locally).
I reckon 90%+ of people buying flash memory buy the cheapies (a
statistic pulled from thin air but probably not far from the truth),
whether that be CF or SD, but would love to be proved wrong. On this
site there would likely be a larger proportion-than-average of
enthusiasts buying the higher-speeds, though.
