Can I use an electronic flash in poor lighting conditions and what kind is the best to buy, I have a Canon EOS REBEL T3
Given the following facts:
* The EOS Rebel T3 is an entry-level (but decent) DSLR: APS-C format, 12.2 MP
* Therefore it has an EF-S lens mount and takes EF-S lenses
* Production was discontinued by Canon in 2012
* The camera is way out of warranty
It's reasonable to conclude:
* You'll probably be replacing this camera in the next few years
Some additional facts about your camera:
* It uses Canon's E-TTL II wireless flash system--still Canon's latest but now 15 years old
* It has a Canon proprietary hotshoe (with ISO-standad center terminal)
At the time when you replace your camera, it's possible that:
* Canon may have moved on to another iteration of its flash system, say E-TTL III, or
* You may decided to upgrade to a FF DSLR, which means you'll be tossing your lenses, or
* You might decide to buy a mirrorless camera (EF-M mount), or
* You might decide to buy a different brand of camera.
If you buy a different brand of camera, a dedicated Canon speedlite won't work with it,
Therefore, I agree with previous posters: don't buy an expensive Canon speedlite.
That leaves you with four choices:
* Buy a used Canon E-TTL II Speedlite
* Aftermarket E-TTL II compatible speedlite -- cheaper than Canon, but still won't work another brand
of camera.
* Smartflash (also called "thyristor controlled" or "auto thyristor") -- compatible with any camera with a
hotshoe, but doesn't meter through the cameras lens (not "TTL" metering)
* Dumb flash -- compatible with any camera with a hotshoe, , but doesn't meter at all. .
Let's rule out dumb flash. You have to guesstimate the proper exposure by dividing the flashes
"Guide Number" by the distance to the subject. Doesn't take the reflectivity of the room into
account. With experience it can be done, but it's not easy.
You take a risk buying a used speedlite. I just bought a 40 year-old studio flash system and
four heas, and it turned out they all worked perfectly. I got luckly. Also, the manufacturer
is still in business and parts are still available. And I'm retired from the electronics industry
and do all my own repairs. Old speedlites are hard to work on and are rarely worth fixing if
you get charged for the labor. If you find one at at thrift store for $10, buy it!
A brand new ETT-L II aftermarket flash can be alot cheaper than Canon, but it's hard to know
what you're getting in terms of compatibility and quality. Most of them are made in China by
China-based companies. You'd hae to read the reviews carefully.
I would buy a smartflash:
* Works with any camera having a hot shoe
* Does meter reflected light--using a photocell on the flash itself
* Not exccessively expensive
Many older smartf lashes used high voltage that would fry your Canon camera (Nikons can
tolerate higher voltage and old mechanical camers don't care.) That's why I didn't put used
this option on the list. There is an adapter--the Wein Safe-Sync--that allows high voltage
flashes to be used with digital cameras (including Canon), but it's not cheap and getting
hard to find, it's another thing to worry about.
Here are the features to look for in a smat flash (most important first):
1. Manufactuer that has been making strobes for a while. The old standby was Vivitar,
but they are gone. The Vivitar brand is now owned by Sakar International. The new
"Vivitar" 285HV -- introduced by Sakar in 2007--differs in many details from the original.
I don't own the original (and an original 283) so I can't vouch for the copy.
2. "Sufficient light" indicator lamp -- if you take a "test" flash, it tells you if you need to
stand closer to the subject
3. Brightness (in true Watt-seconds)
4. Tiltable head
5. Zoom-able head (to match the angle-of-view of your lens, so you don't waste light)
6. Removable light sensor. If the flash is mounted on a tripod, the sensor can still
be mounted on the camers's hotshoe (using an extension cable that has to
be purchased separately). So far as I know, only the Vivitar 283, 283H, 285, and
285H and the Sakar "Vivitar" 285HV have this feature.
7. Fast recycle time -- not very important for most amateur photography
You may be wondering why it's all so complicated.
Primarily, it's because:
* There is no industry standard for TTL-metered flash
* There is no industry standard for hotshoes except the ancient ISO 1-connector
hotshoe (thank heaven we at least have that!)
* Camera buyers tolerate lack of standardization (which car buyers don't tolerate:
Ford cars do not require Ford motor oil or Ford gasoline or Ford tires or Ford
spark plugs or Ford headlights, etc.
* Makers of digital cameras with built-in flash use the flash use the flash for
multiple purposes. Many flash
three times per exposure: once to
measure the reflectivity of the room, once to eliminate red-eye, and once
to take the picture!
* Buyers want wireless triggering--which adds a whole new level of complexity
Maybe somebody here has experience with the Sakar "Vivitar" 285HV?
Also, does anybody know if it's still in production?
