Hello,
Well, I shoot mainly Fujichrome Provia and some Velvia with my F5, usually with a 50mm 1.8 G lens. With the narrow latitude transparency film has, and the extra cost both in terms of the film itself and E-6 developing (even if I do do it myself, which I just started doing), when compared to B&W, I like to make sure if I need a flash that it will produce the best results possible given the non-studio settings in which I operate. With the G lens, it should take advantage of the flash's monitor pre flashing, just wondering if it really makes a consistent difference when compared to the sb-24 which is still TTL, but not using monitor pre flashing. If the SB-28 will give me more consistently accurate exposures (esp with bounce flashing, which I almost always use) then I would like to switch to it. Just wondering if anyone has had any actual hands on time with both on an F5 and if they noticed any difference in consistency (esp with bounce flashing).
go for the SB-28, the Metz 54 MZ-4i with the dedicated SCA adaptor or the SB-800. With all three you will get significantly better results as with the SB-24.
The SB-800 has also the advantage of the current improved i-TTL system: So if you may upgrade to an F6 in the future (which I can highly recommend from my experience with both the F5 and F6) you already have the perfect fit with the SB-800 (which is also downward compatible to all former Nikons).
I am using the Metz but mostly two SB-800 on my Nikons. Excellent flashes. And in combination with the F6 the SB-800 is a dream combination for flash photography.
But especially for normal photography where a fill-in flash is helpful to manage high contrast scenes:
You get perfectly exposed pictures whith detail both in highlights and shadows. With manual override you can illuminate the scene perfectly. So perfect, that mostly no one is realising that a fill-in flash was used, because the pictures are looking so natural.
As you I am also often using reversal film. High contrast scenes? No problem at all for fill-in flash with the F6 / SB-800 (or F5), it works perfectly.
So you can enjoy all the advantages of reversal / slide film, and you don't have to make a compromise concerning dynamic range. Win-win situation, outstanding results.
Best regards,
Henning
