I am in need for a very compact flash to use on a variety of cameras (not nikon) with xsync hotshoe. Of course, the flash will not TTL and be used in manual mode only. The goal here is compactness (usually used for fill and easy to fit in a pocket) and usability in full manual. As such, someone recommended that I check out the Nikon SB-27 shown here: http://www.mir.com.my/rb/photography/hardwares/classics/nikonf4/flash/SB27/index.htm Looks great and the trigger voltages seem to be low enough and it seems like a very small sized flash. So questions for Nikonians out there with this flash: - In manual mode, is it easy to adjust power to the flash? Ideally just an up and down button to control the power. 1/2, 1/4, 1/8 power.. - Can I manually control the zoom head? - Does it have an auto mode similar to the auto-thrystor flashes from Sunpack or Vivitar? - The photos make the flash seem very compact.... is it really? - Any opinions on the SB-27.. remember I'm using this flash in full manual mode only. for reference.. My current flash unit for walk around is an old Sunpack Auto 422 D thrystor and for bigger flash jobs I use a Canon 550EX with high voltage battery pack (modified for D cells for fast recycle and batt life). Both are rather too large for my tastes... The other consideration is the Leica SF24D which will work in manual with all and TTL meter with some (a big plus). The problem as with many Leica products is the price tag... and I don't use flash enough to justify it. It also uses a camera battery of sorts rather than regular AAs which I can for see as inconvenient. Size wise, I'm hoping for something the size of the Nikon SB-400 (even has a bounce head.. neat) but alas the SB-400 is not really compatible with anything but Nikon cameras. Thanks ahead for your opinions... any other very compact, full manual flash I should consider.
