Dear list members, I would like to leverage your expertise to help me to make a jump to flash photography. The camera I'm using is the FM2n, which provides no TTL flash metering. I am mostly interested in using flash as a fill, and maybe sometimes as the only light source. With this in mind, I have three questions to the list: 1. How do you use non-TTL flash as a fill? 2. As the only light source? 3. Which flash would be most suitable for the FM2n? I realize that something like SB28 can do the job, but isn't it a bit of overkill? Most of my photography is cityscapes, travel, and people. About 3/4 of all my pictures are taken by two prime lenses: 105/2.5 AI and 28/2.8 AIS. The rest is taken with the 75-150/3.5 zoom lens, with occasional use of the 50/1.8 AFD and the 28-70/2.8 Tokina. Any help you can provide will be greatly appreciated.
