Hi, I'm just about to purchase a Nikon SB-23 flash gun for my F70. I already have a SB-28 but I need one which is smaller for general purpose stuff. I will also be using the SB-23 mounted on the camera as a fill in flash in conjunction with the SB-28 on the Su-4. I'd appreciate peoples comments on the SB-23 and this combination as I havent played around with the SB-23 at all. thanks Lal D. Lal C. Dissanayake Jnr [EMAIL PROTECTED]
