Re: 7hi is actually SLOWER than 7i

Bill,

Have you tried how long it took you between shots to shoot in Extra Fine mode? Thanks.

I just tested how long it took my new 7hi to save a RAW file, using
the procedure spelled out in Bryan Biggers's site:

http://webpages.charter.net/bbiggers/DCExperiments/html/dimage_flash_card_speeds.html

With the Ridata 512MB card ("20x"), it took about 16 seconds.
According to Bryan's list, the same kind of card in a 7i performs
the save operation in only about 10 seconds.

I also tested a Delkin 256MB, which also took 16s compared to 11s
with the 7i on the list.

My guess for why the 7hi is slower is that it allows you to start
taking additional pictures immediately after you snap the RAW shot.
So the processor is partially occupied with running the LCD and
being ready to record. Therefore, it gives fewer cycles to the
transfer process. If anyone has any other possible explanations,
I'd be interested!

This is not a complaint about the 7hi. In terms of functionality,
the slow saving by the 7hi is really preferable to the faster save
by the 7i, because you can be taking pictures while the save is in
progress.
