This is a very nice feature. More physical changes Every time I change batteries in the EX above left , I have this little fear that I am going to break the battery door off while trying to get it open.

Fear no more - the EX II has a new door above right. Slide the round button sideways and then down - the battery door springs up for clear access to the 2x2 square not staggered oriented AA batteries. This is the way it should have been in the first place. While on the battery topic The EX II is rated for approximately to shots from new AA-size alkaline batteries which deliver a fast recycling time of approximately 0.

For quick flash firing a not-completely-charged flash , recycle times range from. Canon's manual states "Using size-AA batteries other than the alkaline type may cause improper battery contact due to the irregular shape of the battery contacts.

Don't use alkalines - NiMH batteries will save you lots of money and will work better. NiMH batteries also give more consistent full power until they are discharged while alkalines will recycle the flash more and more slowly as they expend their life. Adding environmental concerns and cost to this equation should make the decision to use NiMH batteries a no-brainer. Buy lots of them and use them in everything you own that accepts them get a smart charger such as is made by Powerex.

Eneloop AA batteries come highly recommended. Auto Power-Off on the Speedlite EX II normally kicks in after 90 seconds of inactivity when the flash is not set up as a slave unit. However, there is a thermistor inside the Speedlite that prevents the flash from firing when internal temperature exceeds a certain unspecified level.

If the thermal cutoff kicks in, the flash cannot be fired until it cools down sufficiently. This usually takes about 15 minutes. Fn 14 disables Auto Power Off, but it does not disable the thermal cutoff. Fn Modeling Flash C. Fn FEB sequence C. Fn Flash Metering Mode C. Fn Quickflash with continuous shot C.

At certain shutter speeds, the second curtain starts to close before the first curtain is completely open - standard flash mode needs a wide open aperture for the instant it flashes light.

In HS mode, the faster the shutter speed, the shorter the effective flash range will become. Use second curtain flash synch when taking an exposure with subject motion blur - the motion will flow to the end of the exposure which will be accented by the flash. FEC overrides the camera setting while other settings are determined by the location of the last adjustment.

The zoom setting can be set manually for creativity or automatically by the camera communicating with the flash.

The zoom setting is optimized for the camera and lens being used - Less light is wasted, battery life is maximized. A lens wider than 24mm or equivalent framing requires the pull-out and flip-down diffuser panel to be used for complete frame flash coverage. Rotating the flash head to bounce position results in a 50mm zoom position. Using one button , the EX II head rotates degrees to both sides as well as 90 degrees upward and 7 degrees downward. When using bounce flash, consider also using the retractable catch light panel.

This is a white, semi-rigid plastic-like panel meant to create a bright reflection in the subject's eyes. The catchlight panel is only useful to a certain distance as the reflection size becomes too small to be useful at some point.

Canon's better Speedlite flashes include an AF-Assist Beam to enhance autofocus performance in low light conditions see the red window on the front of the flash?

AF assist projects a red pattern of light that creates enough contrast for the camera to autofocus on even a solid-colored wall. The AF assist beam is functional within its range: 2' This is a powerful feature that I use a lot. Note: Even when disabled, the master flash will fire a preflash - making it appear to be enabled.

Canon Speedlites use light not RF from the flash head for simple wireless flash communications. This is basically a line-of sight system though indoor use can include non-line-of-site remotes if the light bounces off objects in the room sufficiently to communicate with the remote flash es.

The transmission range for wireless communication are periphery-center Four slave channel IDs are available to avoid conflicts with other photographers. Why use an external flash? The answer may be obvious to owners of camera bodies without a built-in flash, but not so clear to those using bodies with a built-in flash.

The built-in flash is great for fill flash to light the shaded areas such as people's eyes in a pictures. The built-in flash is also useful for adding catchlights sparkle in a subject's eyes. The next most-obvious answer is to raise the flash high enough from the camera that the lens and lens hood do not block the light - creating shot-ruining dark half moons in pictures. Because the light source is very small and is located very close to the imaging axis, using the built-in flash as a main light often results in a harshly-lit picture often with red-eyed subjects.

To some degree but the key to using Speedlight's on location is to make every attempt to NOT shoot in midday Sun and choose location and time of day more carefully. If you have any control over those things then you can do brilliant work with Speedlight's and you won't have to push them as hard. You'll also have the ability to dial things in more the way you want rather than what you're forced to do because of a strong Sun or too much ambient contribution.

Find some shade or a tree with dappled light. Shoot in the early morning or late afternoon. There ARE solutions. I shoot predominantly with speed lights and handle flashes.

I've gotten my hands on some studio equipment but it doesn't always suit my needs as well. That said I'll take a pair of Einstein s and matching Lithium batteries at any time. Just sayin'. Back to the speedlights. You hit on one "problem" which is: for as powerful as they are, you are making things harder on yourself if you want to soften the light too. For a rule of thumb, say that a powerful speed light is about Ws. Some smaller, older, more delicate flashes put out a lot less.

So, you can see, you don't have quite the flexibility to "eat light" by adding modifiers as compared to say, an Einstein at Ws. In midday sun, I use gels and bare flash. It works even in sunny 16 territory or even a bit brighter from reflections. I "cheat" with a faster sync speed. The umbrella may come out closer to dusk. Then there is the whole ganging of speedlights trend that some of the better sponsored guys are doing.

Cool, but expensive and pretty cumbersome. I use a Speedlight kit with a Softlighter and 24" x 32" softbox with no problem at all. I just choose location and time of day accordingly. Then I can create whatever light or flash to ambient relationship I want rather than being bullied by the ambient light. Totally agreed. The other small point is that flash durations start to come into play at full power in some speedlights and for some targets.

Would you like to buy a vowel? Go ahead, spin the wheel. As Robert points out, time of day is a big factor. You just can't backup the light and do an entire adult or a big group. Approve the Cookies This website uses cookies to improve your user experience.
