My 8spd is a HG50 from Shimano.

Since this thread has already gone well beyond answering the original question, I'll add to the confusion.
It is possible to shift a Shimano 8-speed cassette with a Shimano 9-speed shifter if you use an 8-speed Dura-Ace rear derailleur. As it turns out, the Dura Ace 8-speed shifter cable pull is the same as the cable pull of all Shimano 9-speed shifters. The reason this works is that the 8-speed D-A rear derailleur actuation ratio is different and when combined with a 9-speed shifter the travel for each click matches the 8-speed cog spacing "perfectly".
Take a look at this chart, scroll down to Shimano mech:

I have a DA7800.
yes it worked flawlessly with my 8speed components.
I have an Ultegra FD too. My bike is a smorgasbord of Shimano parts. All I need is to throw in some 105 brakes and it will be a rolling parts bin for Shimano. Maybe get Yumeya Ti-Nitride chain too?
