It's a personal thing. Depends on how and what you shoot. I've used my flash maybe a half dozen times in almost forty years. Others use flash all the time and couldn't get by without it.Flash, Should I get one?
BTW, the Minolta SRTs are great cameras. I still shoot the first one I bought in 1968!
Also, a fellow named John Titterington (email: JTCamera@aol.com) is a great repair tech -- in case your meter gets stuck or the shutter bearings dry out. He's a whiz with SRTs! Very reasonable prices, too.
