Originally posted by julbelle I've been researching about external flashes online but feel a little confused. I would like to get a flash for my pentax k5 in simple terms can someone pls explain the differences in the flash systems.
Im mainly looking for some bounce when I shoot outdoors in the shade and probably inside a some. I know it sound stupid to use outdoors but I used one withy old camera and it did help a bunch outside.
Here's the Readers Digest version:
1. I think you mean fill instead of bounce for shooting outdoors. Bounce you can do indoors, when you have a wall or ceiling the light can be reflected or bounced back from. Flash is often used outdoors for fill ( especially on sunny days) or even as main or key light.
2. You can get along with $50 to $60 manual flash, like a
Yongnou 560, which has an adjustable output and can tilt, swivel and zoom. You will be balancing flash and ambient light. With a little practice and study, it will do most of what you need. Add an umbrella, stand and some inexpensive wireless triggers and you can do quite a lot.
Study and practice is more important than gear. The main idea when using flash is to understand you are making two exposures, one for ambient and one for what the flash will light.
Here's a great free site with everything you need to know :
Neil van Niekirk Tangents Indoors, I always use the black foamy thing indoors.
3. The Pentax 540 model flashes and a few others ( Sigma & Metz) are a lot more expensive but can work automatically using P-TTL exposure. They can also be used on camera in HSS (High Speed Sync) useful on bright sunny days with high shutter speeds. The trade off is limited distance.
I always use manual exposure on my cameras but will often use my flash in P-TTL mode, usually adjusted with some -EV dialed in on the flash. More and more, I just use manual. mode on the flash.
4. I recommend you buy a $60 Chinese knockoff Yongnuo 560II and learn. Even if you later buy a Pentax 540 ( check shareasale.com/r.cfm?b=889257&u=523490&m=66875&urllink=keh.com for used), you'll still use the Yongnuo, its about the same power output. If you drop it or break it, no big deal. BTW, both will work just fine with these
triggers for off camera use. I carry my tripod with a small softbox & flash around on portrait shoots.
Some examples:
On camera, Pentax 540 flash, HSS
Off camera, manual flash as main light through umbrella, under tent in street.
Off camera, bare manual flash, outdoors in afternoon
Off camera, bare manual flash.
