I'm on the market for a separate flash unit. This is my first flash and I'm on a very tight budget so the SB-600, 700, 800 and 900 are sadly out of the question. Also, the SB-400 (which looks like a nice first flash) is not compatible with the D100.
I'm now looking to get an older flash (from the D100's time) on eBay, at a fraction of the price. I am looking at an SB-25DX. I know, it's not a great flash, but all the other flash units from that 'era' are still quite expensive given their age.
I have read that it has inbuilt remote capabilities derived from it's sensor, and triggered from pre-flashes from a commander unit. My question is this: can I use the Nikon D100 and it's inbuilt flash as a commander for this purpose, or is it too old to support such features?
