Dewman,
Your photographic skills will transfer and probably put you ahead of many. One area that you might want to study up on though is what is often called the "digital workflow". With film you put slides and prints in boxes or trays and had some system of organizing and finding images. IMHO this is the biggest change in going digital. And I see it all the time, even with younger folks that supposedly are computer savvy. They take pictures, but fail to keyword and organize them properly and therefore lose track of them. They have images scattered across 2 or 3 computers, a cell phone and tablet and maybe an external drive or two, and no idea what is where. Part of the problem is that it is too easy to take pictures, with film you watched every shot, because it cost money, with digital it is too easy to just bang away.
Digital workflow is what happens after you take the shot. How does that image get uploaded to the computer, post processed, key worded, titled and captioned, stored on the computer and backups made. What software is used to do that? What system are you using to organize things on the computer? How and when are backups made? This isn't the fun part, that's why they call it 'workflow' but it is vital to being able to enjoy your images a year from now.
Anyway, I hope you give that some thought while you are learning about the fun stuff like camera bodies and lenses.
What lenses do you have with that ME Super? You do know they can still be used on modern Pentax cameras right?
Just noticed where you are from, I drive through there on business several times a year. As things go out here we are practically neighbors.
Best,
John
