For about thirty dollars you can pick up a used Pentax AF280T somewhere. For about thirty minutes of your time you can learn all you need to know to use it. And there isn't a soul on earth who can tell the difference between a photo shot with that and one shot with a brand-new $500 flash.
Just recently I shot
every single one of these with a $30 AF280T left over from the 1980s and
all of these with a $10 AF200T from the same era.
Another flash picked up for $10, an early-1980s National PE-3057 provided the light for these
For the first one, twenty bucks supplied the lens.
My point for the original poster is that just because taking pictures is a hobby that
can require a lot of money doesn't mean that it is a hobby that
must require a lot of money. In the final rubber-meets-the-road analysis of flash photography all
ANY flash unit does is provide a measured output of light. Some offer more automation or bells-n-whistles than others which are intended to make your life a little easier and some are capable of providing a bigger dose of light than others...but when all is said and done they all do the exact same thing. That being the case....combined with the simple fact that I am poor....I have never seen the
need to buy brand-new top-dollar flash equipment. This is one area where a little time and effort spent learning what are truly the very simple basics of using a flash can save you hundreds upon hundreds of dollars with no deleterious effect on your photography whatsoever. If you have to scrimp in some area of photography, this is
the area to do it in.
I'm not telling you
not to get the 540 or one of the units from Metz; I am sure they are fine products and would serve you well. I simply wish to point out that you can dip your toes into the flash photography pool for very little investment and see how you like the water if you like instead of having your wallet do a cannonball off the high dive first.
(If you get really bored, I have a couple thousand photos in a Flickr set titled
Low-Budget Flash, thrown together just to illustrate the point I have tried to make here)
